If any of the following statements does not comply with the applicable legislation, the stricter of the two shall apply. 4. Installation, operation, maintenance and repair work must only be performed by authorized, trained, specialized personnel. 5. The dryer is not considered capable of producing air of breathing quality. For air of breathing quality, the compressed air must be adequately purified according to the applicable legislation and standards. 6. Before any maintenance, repair work, adjustment or any other non-routine checks, stop the dryer, press the emergency stop button, switch off the voltage and depressurize the dryer. In addition, the power isolating switch must be opened and locked. 7. Never play with compressed air. Do not apply the air to your skin or direct an air stream at people. Never use the air to clean dirt from your clothes. When using the air to clean equipment, do so with extreme caution and wear eye protection. 8. The owner is responsible for maintaining the unit in safe operating condition. Parts and accessories shall be replaced if unsuitable for safe operation. 9. It is not allowed to walk or stand on the dryer components

7 1.3 Safety Precautions during Installation All responsibility for any damage or injury resulting from neglecting these precautions, or non-observence of the normal cautio and care required for installation, operation, maintenance and repair, even if not expressly stated, will be disclaimed by manufacturer. Precautions during installation 1. The machine must only be lifted using suitable equipment in accordance with the applicable safety regulations. Loose or pivoting parts must be securely fastened before lifting. It is strictly forbidden to dwell or stay in the risk zone under a lifted load. Lifting acceleration and deceleration must be kept within safe limits. Wear a safety helmet when working in the area of overhead or lifting equipment. 2. Install the dryer as level as possible and fix it firmly to the floor. 3. Place the machine where the ambient air is as cool and clean as possible. If necessary, install a suction duct. Never obstruct the air inlet. Care must be taken to minimize the entry of moisture at the inlet air. 4. Any blanking flanges, plugs, caps and desiccant bags must be removed before connecting the pipes. 5. Air hoses must be of correct size and suitable for the working pressure. Never use frayed, damaged or worn hoses. Distribution pipes and connections must be of the correct size and suitable for the working pressure. 6. The aspirated air must be free of flammable fumes, vapors and particles, e.g. paint solvents, that can lead to internal fire or explosion. 7. Arrange the air intake so that loose clothing worn by people cannot be sucked in. 8. No external force may be exerted on the air outlet valve; the connected pipe must be free of strain. 9. If remote control is installed, the machine must bear a clear sign stating: DANGER: This machine is remotely controlled and may start without warning. The operator has to make sure that the machine is stopped and that the isolating switch is open and locked before any maintenance or repair. As a further safeguard, persons switching on remotely controlled machines shall take adequate precautions to ensure that there is no one checking or working on the machine. To this end, a suitable notice shall be affixed to the start equipment. 10. Air-cooled machines must be installed in such a way that an adequate flow of cooling air is available and that the exhausted air does not recirculate to the compressor air inlet or cooling air inlet. 11. The electrical connections must correspond to the applicable codes. The machines must be earthed and protected against short circuits by fuses in all phases. A lockable power isolating switch must be installed near the compressor. 12. On machines with automatic start/stop system or if the automatic restart function after voltage failure is activated, a sign stating "This machine may start without warning" must be affixed near the instrument panel. 13. Never remove or tamper with the safety devices, guards or insulation fitted on the machine. Every pressure vessel or auxiliary installed outside the machine to contain air above atmospheric pressure must be protected by a pressure-relieving device or devices as required. 14. Piping or other parts with a temperature in excess of 176 F (80 C) and which may be accidentally touched by personnel in normal operation must be guarded or insulated. Other high-temperature piping must be clearly marked

8 15. For water-cooled machines, the cooling water system installed outside the machine has to be protected by a safety device with set pressure according to the maximum cooling water inlet pressure. 16. If the ground is not level or can be subject to variable inclination, consult the manufacturer. 17. Make sure that all piping is installed stress-free. If the maximum pressure of the compressor is higher than the design pressure of the dryer, a full flow safety valve must be installed between the compressor and the dryer in order to blow-off the excessive pressure in case the safety valve of the dryer should be out of order or blocked Also consult following safety precautions: Safety precautions during operation and Safety precautions during maintenance. These precautions apply to machinery processing or consuming air or inert gas. Processing of any other gas requires additional safety precautions typical to the application which are not included herein. Some precautions are general and cover several machine types and equipment; hence some statements may not apply to your machine 1.4 Safety Precautions During Operation All responsibility for any damage or injury resulting from neglecting these precautions, or nonobservance of the normal caution and care required for installation, operation, maintenance and repair, even if not expressly stated, will be disclaimed by the manufacturer. Precautions during operation 1. Never touch any piping or components of the compressor during operation. 2. Use only the correct type and size of hose end fittings and connections. When blowing through a hose or air line, ensure that the open end is held securely. A free end will whip and may cause injury. Make sure that a hose is fully depressurized before disconnecting it. 3. Persons switching on remotely controlled machines shall take adequate precautions to ensure that there is no one checking or working on the machine. To this end, a suitable notice shall be affixed to the remote start equipment. 4. Never operate the machine when there is a possibility of taking in flammable or toxic fumes, vapors or particles as indicated on the principal data sheet. 5. Never operate the machine below or in excess of its limit ratings. 6. Keep all bodywork doors shut during operation. The doors may be opened for short periods only, e.g. to carry out routine checks. Wear ear protectors when opening a door. 7. People staying in environments or rooms where the sound pressure level reaches or exceeds 90 db(a) shall wear hearing protection. 8. Periodically check that: All guards are in place and securely fastened All hoses and/or pipes inside the machine are in good condition, secure and not rubbing There are no leaks All fasteners are tight All electrical leads are secure and in good order

9 Safety valves and other pressure-relief devices are not obstructed by dirt or paint Air outlet valve and air net, i.e. pipes, couplings, manifolds, valves, hoses, etc. are in good repair, free of wear or abuse 9. If warm cooling air from compressors is used in air heating systems, e.g. to warm up a workroom, take precautions against air pollution and possible contamination of the breathing air. 10. Never operate the machine when there is a risk of taking inflammable or toxic fumes, vapors or particles. 11. Do not remove any of, or tamper with, the sound-damping material. 12. Never remove or tamper with the safety devices, guards or insulations fitted on the machine. Every pressure vessel or auxiliary installed outside the machine to contain air above atmospheric pressure shall be protected by a pressure-relieving device or devices as required. Also consult following safety precautions: Safety precautions during operation and Safety precautions during maintenance. These precautions apply to machinery processing or consuming air or inert gas. Processing of any other gas requires additional safety precautions typical to the application which are not included herein. Some precautions are general and cover several machine types and equipment; hence some statements may not apply to your machine All responsibility for any damage or injury resulting from neglecting these precautions, or nonobservance of the normal caution and care required for installation, operation, maintenance and repair, even if not expressly stated, will be disclaimed by the manufacturer

10 1.5 Safety Precautions During Maintenance or Repair Precautions during maintenance or repair 1. Always use the correct safety equipment (such as safety glasses, gloves, safety shoes, etc.). 2. Use only the correct tools for maintenance and repair work. 3. Use only genuine spare parts. 4. All maintenance work shall only be undertaken when the machine has cooled down. 5. A warning sign bearing a legend such as "work in progress; do not start" shall be attached to the starting equipment. 6. Persons switching on remotely controlled machines shall take adequate precautions to ensure that there is no one checking or working on the machine. To this end, a suitable notice shall be affixed to the remote start equipment. 7. Before removing any pressurized component, effectively isolate the machine from all sources of pressure and relieve the entire system of pressure. 8. Never use flammable solvents or carbon tetrachloride for cleaning parts. Take safety precautions against toxic vapors of cleaning liquids. 9. Scrupulously observe cleanliness during maintenance and repair. Keep dirt away by covering the parts and exposed openings with a clean cloth, paper or tape. 10. Never weld on, or in any way modify, pressure vessels. 11. Whenever there is an indication or any suspicion that an internal part of a machine is overheated, the machine shall be stopped but no inspection covers shall be opened before sufficient cooling time has elapsed; this to avoid the risk of spontaneous ignition of the oil vapor when air is admitted. 12. Never use a light source with open flame for inspecting the interior of a machine, pressure vessel, etc. 13. Make sure that no tools, loose parts or rags are left in or on the machine. 14. All regulating and safety devices shall be maintained with due care to ensure that they function properly. They may not be put out of action. 15. Before clearing the machine for use after maintenance or overhaul, check that operating pressures, temperatures and time settings are correct. Check that all control and shutdown devices are fitted and that they function correctly. If removed, check that the coupling guard of the compressor drive shaft has been reinstalled. 16. Never use caustic solvents which can damage materials of the air net, e.g. polycarbonate bowls. 17. The following safety precautions are stressed when handling desiccant: Take precautions not to inhale desiccant dust. Check that the working area is adequately ventilated; if required, use breathing protection. Do not overfill the dryer when replacing desiccant

11 Also consult following safety precautions: Safety precautions during installation and Safety precautions during operation. These precautions apply to machinery processing or consuming air or inert gas. Processing of any other gas requires additional safety precautions typical to the application which are not included herein. Some precautions are general and cover several machine types and equipment; hence some statements may not apply to your machine. After maintenance or repair, a functional test with depressurized vessels must be performed to check the correct operation of the dryer

16 Automatic control of the dryer The controller maintains the pressure dewpoint between programmable limits automatically by defining the switching time. A number of time-based automatic start/stop commands may be programmed (see section Programming clock functions). Take into account that a start command will be executed (if programmed and activated), even after manually stopping the dryer. Protecting the dryer Service warning A number of service operations are grouped in plans (called Service plans A, B and C). Each Service plan has a programmed time interval. If a time interval is exceeded, a message will appear on the display to warn the operator to carry out the service actions belonging to that plan. Warning A warning message also appears if: The pressure dewpoint exceeds a programmed value. Automatic restart after voltage failure For dryers leaving the factory, this function is made inactive. If desired, the function can be activated. Consult Quincy Compressors

19 Description Wet compressed air enters the system and flows to the bottom of one of the towers (A or B) via valve (V1) or (V2). After passing through the desiccant, which adsorbs the moisture contained in the inlet air, the dry compressed air leaves the dryer via outlet valve (V11 or V12). The moisture in the drying tower is removed during regeneration Regeneration Circuit Flow Diagram Please refer the Flow diagram from Air circuit section 2.3 Description The wet desiccant beads are dried in the regeneration stage. The tower is depressurized via blow- off valve (V3orV4). A small portion of the dried air flows via nozzle (114) to the tower to be regenerated. The air is expanded to atmospheric pressure and flows downwards through the desiccant beads. The regenerating air is released via the exhaust valve (V3 or V4) and the silencers (109). 2.4 Shifting Towers Flow diagram Please refer the Flow diagram from Air circuit section Description The operation cycle of the dryers is repetitive and is controlled by the controller. While the desiccant in the first tower dries the compressed air, the desiccant in the second tower is being regenerated and vice versa. Regeneration of the desiccant is achieved by means of purge air from the dryer outlet. A small portion of the dried air flows via the control air valve to the solenoid valves which are controlled by the controller. The air leaving the solenoid valves (when energized) is used to control the pneumatic actuator and the pneumatic valves. After a certain period, the cycle will restart. The fully regenerated tower will be pressurized. Later, the inlet air switches tower and the wet tower is depressurized via the silencers. Then regeneration starts and the purge air flows through the vessel and a silencer. Then the regenerated tower will start drying the compressed air and the other tower will be regenerated

The dryer has two towers, containing the adsorbing material or desiccant. The desiccant is a very porous grain material which can adsorb large amounts of water vapor. The operation cycle of the dryer is repetitive and is controlled by a factory-set timer, located inside the cubicle (3)

21 The compressed air entering the dryer is led to one of the towers by means of the inlet valves (IV), which are controlled by a pneumatic actuator (PA). As the air flows upwards through the tower, the desiccant adsorbs the water vapor and the compressed air is dried. The dry air leaves the dryer via the outlet, connected to the top of the tower. While the desiccant in the first tower dries the compressed air, the desiccant in the second tower is being regenerated. Regeneration of the desiccant is achieved by means of purge air from the drying tower: a small portion of the dried air passes a nozzle (N), expands to atmospheric pressure and flows downwards through the other tower, regenerating the desiccant. The regenerating air is released via the corresponding exhaust valve (PV) and the silencer (S). A second small portion of the dried air flows via the control air valve (CA), a small air filter (AF) and the pressure regulator (PR - only used on 232 psi (16bar) versions) to the solenoid valves (SV). The air leaving the solenoid valves (when energized) is used to control the pneumatic actuator (PA) and the pneumatic valves (PV). The solenoid valves are controlled by the timer. After a pre-set time period, the cycle will restart. The fully regenerated tower will now dry the air while the desiccant in the other tower will be regenerated. Freeze mode By default, the regeneration timer will be reset in case of a power failure during operation or in case the on/ off switch was put in position 0. However, in case the input of remote control connector X3 (also referred to as P4 - freeze contact, see section Electric diagram) was short-circuited, the dryer will switch to <freeze> mode: purge air flow stops, both solenoid valves are closed. When the contact, connected to connector X3 is opened again, the dryer will resume its cycle from where it was stopped and will continue the drying cycle. This feature can prevent loss of compressed air (purge air) when the compressor is not continuously running loaded. On compressors with load/unload regulation, X3 can be connected to a voltage free contact of the compressor (contact closed when the compressor runs unloaded). If no free contact is available, an additional voltage free contact should be installed on the load/unload contactor of the compressor to use this feature. See Electrical connections for more details. Operating principle: during unload operation of the compressor, the regeneration valve of the regenerating tower is closed. That way, the pressure in this tower will increase up to net pressure. From that moment on, purge air is no longer consumed. During load, the regeneration valve is opened and both towers resume their cycle

22 Do not connect X3 when an air receiver is installed before the dryer. X3 should only be connected when the air receiver is installed after the dryer Flow diagram Please refer the Flow diagram from Air circuit section

33 5.2 Installation proposal Piping Make sure that all pipes, filters, valves, etc. are clean and that they are installed correctly with or without bypass system. Make sure that the piping is installed stress-free. For more information concerning air nets, cooling systems etc. refer to the compressor installation manual. To ensure correct operation of the dryer, it has to be fitted properly into the compressed air circuit, consisting of the compressor, the dryer and the application. Depending from the fact if the remote control connector X3 is used or not (see also section Operation), there are two possibilities: Installation in case X3 is not used If the freeze contact X3 is not used, the correct order of installation is compressor air receiver dryer. For information on the <freeze> contact, consult section Electrical connections. Installation proposal if the freeze contact (X3) is not used

34 COMP AR D Compressor Air receiver Dryer EIV External inlet valve (not shown) To cut off the air supply towards the dryer EOV External outlet valve (not shown) To cut off the air supply towards the air consumer BV Bypass valves (not shown on the drawings) Together with the external inlet valve and the external outlet valve, the bypass valves allow the dryer and the filters to be serviced while nondried air flows through the bypass system. Moisture Separator Moisture separator (optional) To prevent free water from entering the dryer. 1 The drain pipes to the drain collector must not dip into the water. For draining of pure condensate water, install an oil/water separator. 2 Minimum free area to be reserved for the dryer installation 3 Compressed air prefilter for general purpose filtration, particle removal down to 1 micron, maximum oil carry-over 0.5 ppm This filter provides extra protection of the dryer and extends the lifetime of the high efficiency filter cartridge (4). 4 High efficiency filter, particle removal down to 0.01 micron, maximum oil carry-over 0.01 ppm To remove remaining impurities. 5 Dust filter, particle removal down to 1 micron To remove dust particles originating from the desiccant. Positioning in case X3 is used If X3 connection is used, the correct order of installation is compressor dryer-air receiver

35 Installation with use of the X3 connection with the compressor General recommendations Keep the following in mind when installing the dryer: Place the dryer at a location where the temperature never exceeds the limits, see Technical Data. The dryer does not require extra ventilation. Fix the dryer as level as possible to the floor. Make sure the fixating bolts are tightened firmly and that the floor is suitable for taking the weight of the dryer. Provide enough space around the unit to install and service the filter elements. A minimum free space of 800 to 1000 mm (approx. 2.6 to 3.2 ft) is recommended - see the installation proposal drawings. Provide sufficient space under the filter elements in order to be able to replace the filter cartridges without the need having to disassemble the piping. Always install a high efficiency filter (4) at the inlet of the dryer. A prefilter (3) is recommended to extend the lifetime of the high efficiency filter. The drain pipes (1) of the water separator and the filters must not dip into the water. Use a dust filter (5) at the outlet of the dryer. Should oil vapour and odours be undesirable, a carbon filter can be installed downstream the dust filter. If the compressor has no built-in water separator, a moisture separator has to be installed before the dryer in order to prevent free water from entering the dryer, as free water can damage the desiccant. If the condensate contains oil, install an oil/water separator for draining of pure condensate water

36 It is recommended to install bypass pipes with ball valves over the filters in order to isolate the filters during service operations without disturbing the compressed air delivery. It is required to install pressure relief valves on each vessel of the dryer when ball valves are installed at the inlet and the outlet of the dryer to isolate the dryer from the air net Never overload the dryer as a too high air speed will damage the desiccant. It may be recommended to install the air dryer upstream of the air receiver to prevent overload (e.g. after extending the dry air circuit). Consult your supplier if in doubt. See also section Operating instructions for the correct operation procedure. 5.3 Electrical connections The electrical wiring must comply with the local regulations. The air dryer must be earthed and protected by fuses against short-circuiting Electrical wiring Below image shows the connection terminals of the timer card: Timer card

37 Supply connection (X9) Connect the supply voltage to terminals 1X0 (L1 - L2) and 1X3 (earth). Install a power switch and fuses in the supply line. See also section Electric diagram. X3 (freeze contact - P4) If you want to use the feature to freeze the regeneration cycle when the compressor runs unloaded, connect pin 1 and 2 of connector X3 with the potential free contact of the compressor (contact closed = freeze). CAN-Bus connection The timer card can be interconnected in a Local Area Network (LAN) with AirConnect (e.g.combox-e). Application: data communication between timer card and AirConnect (e.g. Combox-E). Addressing and CAN protocols used are the same as for the Advanced controllers.

41 6 Operating instructions In your own safety interest, always observe all relevant safety instructions. Initial start-up To start up the dryer for the first time or after a long period of standstill, proceed as follows: 1. If installed, open the bypass valves of the dryer. 2. Close off the air supply from the compressor towards the dryer by closing the external inlet valve (if installed). 3. If installed, close the external outlet valve. 4. Remove the silencers to prevent the silencers from getting clogged by the desiccant and wear a dust mask, safety glasses and ear protection. (This is only required at initial start-up or after the desiccant was replaced). 5. Start the compressor and wait for pressure. 6. Slowly open the external inlet valve. 7. Check the connections of the dryer for air leaks and remedy if necessary. 8. Switch the dryer on by putting main switch S1 in position I. 9. Let the dryer operate for several hours with the external outlet valve closed. 10. In case the silencers were removed, refit the silencers. 11. Gradually open the external outlet valve. 12. If applicable, close the bypass valves of the dryer Normal start If the application allows air that is not completely dry, the valve towards the dry air consumer may be opened even before the optimal PDP is reached. In this case however it will take more time for the desiccant to dry completely. At initial start-up, and specially when the dryer is loaded from the beginning, it can take a long time before the dewpoint is reached. For a dewpoint of -70 C (-94 F), it can take up to more than 10 days before this value is reached If the dryer has not been used for more than 3 months, refer to section Initial start-up. In all other cases proceed as follows: 1. Cut off the air supply from the compressor towards the dryer by closing the external inlet valve. 2. If installed, close the external outlet valve between the dryer and the dry air consumer. 3. Start compressor and slowly open the external inlet valve. 4. Switch the dryer on by putting main switch S1 in position I. 5. Gradually open the air outlet valve. 6. If applicable, close the bypass valves of the dryer

42 Close the external inlet valve in case the compressor needs to be restarted. The high air speed in the start-up phase of the compressor may damage the desiccant. To prevent this, a sonic nozzle (Please consult Quincy Compressors distributor for the sonic nozzles) can be installed During operation At regular intervals, check the status of the LED s on the control panel. Refer to section Problem solving. Stopping To stop the dryer, proceed as follows: 1. If installed and if necessary, open the bypass valves of the dryer so that the application will still receive compressed air. 2. Close the external inlet valve between the compressor and the dryer and the external outlet valve between the dryer and the dry air consumer. 3. Let the dryer operate for a period without consumption, to depressurize the vessels. 4. Switch off the dryer by putting main switch S1 to position 0. If the dryer is stopped for a longer period, keep the external inlet and outlet valve closed to avoid moisture from entering the dryer. Under no circumstances must compressed air be allowed to flow through the dryer when the electrical power is switched off. This will result in terminal failure of the desiccant material, causing regeneration will no longer be possible

43 7 Maintenance 7.1 Maintenance General recommendations and precautions The dryer does not need any specific maintenance. Nevertheless, before carrying out any maintenance or corrective activity read the following recommendations and safety precautions and act accordingly: Switch off the dryer by putting main switch S1 to position 0. Disconnect all pressure sources and vent the internal pressure of the system before dismantling any pressurized component. Use genuine Quincy Compressors spare parts only. Consult the Spare Parts List for part numbers. For preventive maintenance, dedicated Service kits are available. Check for correct operation after maintenance Filters and valves installed between the compressor, the dryer and the air consumer may need other maintenance activities than those mentioned below (e.g. draining the filters and replacing the filter elements). Refer to the appropriate manual for more information. Preventive maintenance schedule Frequency Service plan Activity Daily Every 6 months or every 4000 hours of operation (1) Every year or every 8000 hours of operation (1) A B Check the display panel for information and service messages. Check for damaged wiring or loose connections. Check for air leaks. Replace the in- and outlet filter cartridges. Replace the silencers. Clean or replace the silencer If a PDP sensor is installed, replace its filter cartridge and have sensor re-calibrated. Measure the dewpoint Have the condition of the desiccant checked Inspect the seats of check valve; replace it if necessary

44 Frequency Service plan Activity Every 3 years or C Service plan C every Replace desiccant hours (1) Revision of inlet valves and actuator Replace the check valves Always replace all o-rings, seals and nylon washers that come free when executing the scheduled maintenance. (1) Whichever comes first In normal working conditions, the lifetime of the desiccant is approximately three years. It is recommended to have the desiccant replaced by a qualified Quincy Compressors service technician. After each 8000 hours service interval, the timer card needs to be reset with a magnetic key, see section Resetting the service counter or the instruction, delivered with the service kits. Reset the service timer after a maintenance intervention. See section Resetting the service counter. All spare parts required for scheduled maintenance are included in specific service kits. Consult the spare parts list for part number information. 7.2 Resetting the service counter Timer card resetting procedure To reset the timer card, continue as follows:

45 Close off the dryer as describe in the stopping procedure, see section Operating instructions. Switch off the dryer by putting switch to Off position. LED (2) (dryer operating) will extinguish. Perform the service plan as scheduled. If the service warning LED (9) is already alight, go directly to the next step. If maintenance is being carried out before the service alarm appears (every 8000 hours), the reset procedure needs to be activated before the service counter can be reset to 0. This can be done by placing the service magnet during 3 seconds over the indicated area (A) of the control panel, in the middle of the left tower. As an indication that the reset procedure is activated, the service warning LED (9) will light up. Reset the timer card by putting the service magnet over the indicated area (A) of the control panel during 5 s. The service alarm LED extinguishes. The service counter has now been reset to 0. Also the counter to switch towers will be reset to 0 (only visible in case of timer control). Restart the dryer by switching switch to On. The service counter will restart, the dryer operating LED (2) is alight, and the drying and regeneration LED s indicate the status of the dryer operating cycle. The timer card is now reset and normal operation continues. The service counter has been reset to 0 and will appear again after 8000 hours 7.3 Disposal of used material Used filters or any other used material (e.g. desiccant, lubricants, cleaning rags, machine parts, etc.) must be disposed of in an environmentally friendly and safe manner, and in line with the local recommendations and environmental legislation

46 8 AIRLOGIC2 Graphic controller 8.1 AIRLOGIC2 Graphic controller Control panel General description The AIRLOGIC2 controller automatically controls and protects the dryer, i.e.: keeping the pressure dew-point stable monitoring pressures, temperatures and digital switches to ensure safe operation, and stopping the dryer whenever necessary restarting the dryer when required In order to control the dryer and to read and modify programmable parameters, the controller has a control panel provided with: LEDs indicating the status of the dryer a display indicating the operating conditions or a fault keys to control the dryer and to access the data collected by the controller buttons to manually start and stop the dryer Automatic restart after voltage failure The controller has a built-in function to automatically restart the dryer if the voltage is restored after voltage failure. For dryers leaving the factory, this function is not activated. If desired, the function can be activated. Consult the Quincy Compressors Customer Care

47 Provided the controller was in the automatic operation mode, the dryer will automatically restart if the supply voltage to the module is restored within a programmed time period. The power recovery time (the period within which the voltage must be restored to have an automatic restart) can be set between 15 and 3600 seconds or to Infinite. If the power recovery time is set to Infinite, the dryer will always restart after a voltage failure, no matter how long it takes to restore the voltage. A restart delay can also be programmed, allowing for example the dryer and the compressors to be restarted one after the other. 8.2 Control Panel Advanced controller Parts and functions Reference Designation Function 1 Display Shows the dryer operating condition and a number of icons to navigate through the 2 Pictograph Automatic operation 3 Pictograph General alarm 4 General alarm LED Flashes if a shut-down warning condition 5 Pictograph Service 6 Service LED Lights up if service is needed
