12 4.6 TEMPERATURE SENSOR INSTALLATION AND ELECTRICAL CONNECTIONS When installing the temperature sensing option, run the thermocouple extension cable in a separate conduit and isolated from AC wiring. Make certain that the dielectric bushing is installed through the clean air plenum before installing the thermocouple sensor. The dielectric bushing allows the thermocouple sensor to float and reduces the risk of induced noise on to the extension cable. Figure 5 shows wiring to the Diagnostics Panel when using the temperature sensor FIGURE 5 Temperature Sensor Option 8 United Air Specialists, Inc.

13 4.7 BLOWER CURRENT SENSOR INSTALLATION AND ELECTRICAL CONNECTIONS When installing the blower current sensing option, run the extension cable (twisted pair, shielded) in a separate conduit and isolated from AC wiring. Figure 6A shows blower current sensor wiring to the Diagnostics Panel. Upon completion of the interconnection wiring, follow steps 1 and 2 to complete installation. Step 1 Refer to Figure 6B to determine proper dip switch settings for the motor/blower used. Range in amps indicates the motor FLA. Dipswitch indicates the four ON or OFF positions of the DIP switch labeled BANK 0 located near the bottom center of the main printed circuitboard (part no ) inside the Diagnostics Panel enclosure. Example If the motor nameplate FLA is 22 amps, the BANK 0 DIP switch settings should be on, on, on, on. Step 2 Refer to Figure 6C to determine the proper number of passes through the current transformer. CT means the type of current transformer used for a specific motor FLA range. A pass is the number of times a wire will go through the hole of the current transformer. Example If the motor nameplates FLA is 22 amps, the base mount CT installed in the blower combination starter is part no One conductor of the motor wiring must loop through the opening in the current transformer one time before going on to the motor/ blower FIGURE 6A Blower Current Sensor Option United Air Specialists, Inc. 9

17 5. OPERATION 5.1 SYSTEM FUNCTION The Diagnostics Panel provides a state-ofthe-art cartridge cleaning and monitoring system. The system collects data from several input devices and continuously records the information. The panel then calculates the average of each variable to provide the most accurate measurements possible. The Diagnostics Panel displays a wide range of diagnostic information. The Diagnostics Panel also records operational data for approximately one year. This information is transferable to a computer or portable laptop for future review. The following information describes the function of each feature on the Diagnostics Panel. 5.2 DUST-HOG STATE DISPLAY The DUST-HOG status display is a 16 character, two line, 32 segment LCD display. The display offers two lines of information 16 characters long. Each alphanumeric character is approximately 1/2" high for viewing ease. Any time an operator activates a key (except for the Blower Start or Stop key), the screen will light for viewing ease. If a key is not pressed within 90 seconds, the backlighting shuts off. The 90-second delay acts as a screen saver to preserve the life of the display and keep the operating temperature of the controls as low as possible. The status display gives a wide variety of diagnostic information. Some of the important features are listed below: Acceptable Air Volume Indication (high, low) Cartridge Filter Pressure Drop Plenum Pressures Compressed Air Manifold Pressure Minimum Pulse Delay (in increments of 0.1" w.g.) (in increments of 0.1" w.g.) ( PSI in increments of 0.1 PSI, PSI in increments of 1.0 PSI) (in seconds) Continuous Pulse Delay (in seconds) Time Between Pulses (in seconds) Cleaning Mode Indication (auto-tune, setpoint, continuous, downtime) Downtime Cleaning Cycles (0-10 cycles) Last Valve Pulsed (0-16) Time Since Last Valve (minutes) Pulsed Blower On Timer (hours, decrements of 0.1 hours) Lube Fan Timer (hours, decrements of 0.1 hours) Time, Day, Date (Tue 9/14/99 2:32 PM) Airflow (CFM) Target P, Auto-tune mode High P Setpoint, Setpoint mode Low P Setpoint, Setpoint mode (increments of 0.1" w.g.)

18 5.2.A NEXT AND PREV KEYS The NEXT key allows you to scroll to the next message that will be displayed on the screen. The PREV key allows you to scroll to the previous message. 5.2.B POWER ON Color of light: GREEN The POWER ON light will illuminate when service voltage (115VAC or 230VAC) is applied to the panel. 5.2.C ACTIVE ALARM Color of light: RED The ACTIVE ALARM light will illuminate when an alarm condition is identified. When the alarm condition is no longer active, the ACTIVE ALARM light will turn off. 5.2.D VIEW ALARM When an alarm condition exists (as indicated by the red ACTIVE ALARM light), press the VIEW ALARM key. The first active alarm detected will be displayed on the screen. Press the NEXT key to view any additional alarms. 5.2.E BLOWER OPERATIONAL Color of light: GREEN The BLOWER OPERATIONAL light indicates the motor/ blower starter is energized. The system has a sensor that determines if voltage is applied to the starter coil. When voltage is applied, the system seals the coil and recognizes that the blower is operational. 5.2.F BLOWER START AND STOP KEYS When the blower START key is pressed, the motor/ blower starter, if wired for standard operation, will activate (refer to Figure 3). When the Diagnostics Panel senses that the starter coil is energized, the starter coil seals until the operator presses the blower STOP. However, the blower starter will shut down due to a motor overload or motor over temperature condition. The Diagnostics Panel will indicate if starter circuit is broken by some remote condition. 5.2.G MAINTENANCE ALERT DISPLAY Color of light: YELLOW The MAINTENANCE ALERT display is a group of lights that indicate a potential problem or fault condition. These lights indicate an alarm condition that may occur in the near future. When the alert condition goes away, the light will automatically turn off. Refer to Table 2 for factory default conditions. The alert conditions provided and description are as follows: 5.2.H CHECK COMPRESSED AIR Color of light: YELLOW This light illuminates when the compressed air level falls outside the normal operating range. The compressed air should remain within an acceptable range for optimum cleaning to occur. 5.2.I CHECK PULSE VALVE Color of light: YELLOW The system monitors compressed air pressure during cartridge cleaning (pulsing the valves). The system expects a sudden drop and then a recovery in air pressure from the compressed air line before the next cleaning pulse. If the system does not sense the required pressure drop, this indicates a possible bad or jammed valve may be the problem. The Diagnostics Panel waits for a full pressure recovery after a valve is pulsed. If full pressure recovery does not happen before the next required pulse in a cycle, a check pulse valve condition is eminent. If the condition persists five times in a row, a pulse valve condition is indicated. 5.2.J CARTRIDGE RUPTURE Color of light: YELLOW If the Diagnostics Panel measures either a sudden drop in P across the filters, a rapid decrease in airflow or an unacceptable continuous low P, a cartridge rupture alert is generated. 5.2.K REPLACE CARTRIDGES Color of light: YELLOW If the Diagnostics Panel senses that the P has risen above the acceptable operating range and the cleaning system cannot reduce the P, the cartridges are plugged beyond cleaning and should be replaced. 14 United Air Specialists, Inc.

19 5.2.L REPLACE AFTERFILTERS Color of light: YELLOW If the Diagnostics Panel senses that the afterfilter static pressure has risen above the acceptable operating range, the afterfilters should be replaced. 5.2.M LOW AIRFLOW Color of light: YELLOW When the Diagnostics Panel detects that airflow through the system falls from 40% of the rated airflow to 21% (adjustable), the LOW AIRFLOW light will illuminate. 5.2.N HIGH AIRFLOW Color of light: YELLOW When the Diagnostics Panel detects that airflow rises to 120% of the rated airflow, the HIGH AIRFLOW light will illuminate. 5.2.O 14 KEY MATRIX The 14 key matrix allows you to enter data, when prompted, for input information. The keys are well spaced with large numeric indications for easy use. Each embossed snap-action key provides tactile feedback that a key has been pressed. 5.3 CLEANING MODES The FILTER CLEANING MODE lights indicate what cleaning mode is active. During blower operation, the system can be in only one cleaning mode. Upon starting the blower, the selected cleaning mode will become active following a 45 second start-up delay. The selected cleaning mode will stay active until the blower shuts down. Upon shutdown, the cleaning system will immediately go into downtime cleaning (if the option has been enabled). Possible cleaning modes include autotune, setpoint, continuous and downtime pulse modes. 5.3.A FILTER CLEANING MODE ACTIVATED Color of light: GREEN The FILTER CLEANING MODE ACTIVATED light will illuminate whenever the current cleaning mode is actively pulsing the solenoid valves. When solenoid activity stops, the FILTER CLEANING MODE ACTIVATED light will turn off. 5.3.B AUTO-TUNE PULSE MODE Color of light: YELLOW In this mode, the AUTO-TUNE PULSE light continuously illuminates. The FILTER CLEANING MODE ACTIVATED light also illuminates while pulsing is active. When the blower is running, the auto-tune mode keeps the lowest practical P across the filters while using the least amount of compressed air possible. Auto-tune is sensitive to the needs of the filter P. Once an initial pulse delay is entered, the auto-tune logic adjusts the delay depending on the system loading. As loading increases, auto-tune determines when to pulse, the delay between pulses and an optimum deferential reference setpoint. If loading decreases, auto-tune reduces the P to the lowest possible level. 5.3.C SETPOINT PULSE MODE Color of light: YELLOW In this mode, the SETPOINT PULSE light continuously illuminates. The FILTER CLEANING MODE ACTIVATED light also illuminates while pulsing is active. This mode emulates Photohelic control. If the filter P rises above a present upper setpoint, pulsing of the valves will continue until P falls below the present low setpoint. 5.3.D CONTINUOUS PULSE MODE Color of light: YELLOW In this mode the CONTINUOUS PULSE light continuously illuminates. The FILTER CLEANING MODE ACTIVATED light also continuously illuminates. While in this mode, the system will constantly pulse valves as long as the blower is running. When the blower stops, the pulsing stops. 5.3.E DOWNTIME PULSE MODE Color of light: YELLOW If this mode is selected, the DOWNTIME PULSE light will illuminate once the blower shuts off. The light will remain illuminated until downtime cleaning is complete. The FILTER CLEANING MODE ACTIVATED light continuously illuminates during downtime cleaning. Downtime cleaning is designed to aid in dust removal from the cartridges with no airflow to work against. It serves as a final cleaning after process shutdown. Downtime cleaning will continue for a present number of cycles. Photohelic is a registered trademark of Dwyer Instruments, Inc. United Air Specialists, Inc. 15

47 8. ALARM CONDITIONS AND TROUBLESHOOTING The Diagnostics Panel has a built-in diagnostics system that indicates when an active alarm condition occurs. When an active alarm is present, the red light on the face of the Diagnostics Panel labeled ACTIVE ALARM will illuminate. The alarm light stays on only as long as the alarm condition exists. If the alarm condition is corrected, the active alarm light will turn off. If an alarm condition has occurred, regardless if the problem is present, the system data log will record the event, day and time it occurred and store it for approximately one year in the system memory. If more than one alarm is active, the system will maintain the alarms in the priority they occur. Alarms can be viewed at any time. Possible alarm conditions are: Low airflow Low supply pressure High supply pressure Internal failure Over temperature (optional) Afterfilter high pressure Blower overcurrent Cartridge filter high P Filter rupture Cleaning failure Blower failure Service timer (time expired) Lube fan timer (time expired) If an alarm occurs, the Diagnostics Panel allows you to view possible causes and recommended remedies.
