2 2 Installation and Operation 1. Introduction This frequency controller is used with permanent magnet synchronous motors (PM) or asynchronous motors (AC). Speed can be controlled with a 0-10 V DC signal, potentiometer, Modbus RTU or hand terminal. The hand terminal (PAN-08-0) is not automatically included in the delivery but can be ordered as an accessory. Main voltage requirement is 3-phase 400 VAC. Frequency controller is equipped with an EMC filter. Built-on means that the frequency controller is mounted at the side of the fan. If the fan service side is on the other side, the drive can easily be moved there by opening four screws. Cabling between motor and drive is already done. Built-on version is ready to be used and needs only power from mains and control signals. They can be easily connected to the terminals under the drive s plastic cover. 3. Installation 3.1. Mechanical installation The built-on frequency converter is factory mounted to left side of the fan (when looking from behind of the fan). If needed, the frequency converter can be removed to the right hand side of the fan according to the following instructions. Otherwise please use the cable tie (delivered with the fan) to attach the motor cable to the motor bracket/mounting plate, see point Frequency controller cooling ribs are in the air flow. Surplus heat is removed by active ventilation. 2. Features As standard, frequency controller has the following built-in features Modbus RTU 0-10 V analogue input for controlling speed Control via external hand terminal Indication relays for alarm and running Flying start Alarms for overload, over-voltage and under-voltage Motor and cable protector with built-in current limiter Short-circuit protection against phase to phase short circuiting on motor output terminals Digital input for Start/stop Digital input for Alarm reset or Fire mode Built-in EMC filter Automatic speed reduction in the event of over temperature inside the drive or lacking phase on the supply input Loosen the upper bolts and remove lower fixing bolts (M6) of the frequency converter mounting plate. You might need a 10 mm wrench with the upper front bolt. Upper bolt Lower bolt

3 Installation and Operation Slide off the mounting plate Put the upper bolts (removed from the left hand side) on their places on the right hand side of the motor bracket. Bolts shall be loose enough to get the mounting plate slided to its place. After that, attach lower bolts (also removed from the left hand side) and tighten all bolts Attach the cable tie to motor bracket / mounting plate Electrical installation Frequency converter must only be installed and commissioned by trained and qualified personnel. Incorrect electrical installation may cause risk of severe or fatal personal injury. If natural draught through the duct system causes the fan to rotate even when it has not received an operating signal, there is a risk that the motor will induce voltage on the frequency converter motor terminals, making them dangerous to touch Short circuit protection Correct short-circuit protection must always be used with the frequency converter in accordance with local and international regulations. Short-circuit protection is supplied by the installer Supplementary protection Direct earthing or TN or TT system earthing can be used for supplementary protection Frequency converter must always be supplementary protected with an earthing wire connected to the protective earth terminal (PE). If an RCD/HPFI (TT system) is used, it must be specifically intended for use with motor controllers Potential equalisation There is a risk of electrical interference if the ground potential between the frequency converter and the air handling unit or duct differ from each other. In the event of potential differences between system components, an equalisation conductor must always be fitted. Recommended cable cross section is 10 mm 2. Lugs should be used, and the equalisation conductor should be attached to the frequency converter enclosure via one of the screws used to mechanically install the unit Earth connection (PE) Frequency converter must be earthed in accordance with applicable local and international standards and directives. In power cable, please use an earthing lead which is suitable for the purpose. Frequency converter must be earthed singly and must therefore never be earthed in series. Keep earth connection wires as short as possible.

4 4 Installation and Operation Cable requirements All cables and leads used in connection with the frequency converter must comply with local and national rules and regulations. Shielded cable is not necessary for I/O and Modbus communication. Generally, cable types with copper wires are recommended. For recommended cable dimensions, see table 3.1 below Opening the frequency converter Check that the voltage supply to the frequency converter has been disconnected before opening the cover. Wait approx. 3 minutes after disconnecting mains voltage before removing the cover. Frequency converter is opened by loosening the six Torx20 screws holding the plastic cover in place. Carefully remove the loosened cover. Power Cable gland Cable diameter Cable size, min. Cable size, max. Core sleeve/stripped min.

5 Installation and Operation Mains voltage connection 3~400V, 50Hz Connect power cable to terminals L1, L2, L3 and PE It is recommended that the PE wire is 20 mm longer than the other wires in the cable Remember to re-tighten the cable glands to ensure ingress protection and strain relief mm MAINS L1 L2 L3 PE Modbus connection Frequency converter is equipped with four connectors for Modbus connection. It also features 3 x RJ12 connectors and one strip of spring terminals. On the terminal strip with spring terminals for control signals (A/D I/O), the terminals for connecting Modbus are marked Bus A, Bus B and GND. If wanted, a round cable can be used for Modbus communication, connected to terminals marked Bus A and Bus B on the frequency converter terminal strip. The Modbus terminals are internally connected in parallel to the Modbus pins in the RJ12 connectors marked A and B. The three 3 RJ12 connectors are marked A, B and C. A : Modbus connection, slave, +24V voltage supply in connector. B : Modbus connection, slave, no voltage supply in connector. C : Modbus connection, master, external equipment, e.g. PTH/ VOC. A 6-core, unshielded, 30 AWG/0.066 mm² telecommunications cable or similar type of ribbon cable can also be used for Modbus communication. Attach RJ12 connectors to both ends by using a special-purpose tool. Bus A Bus B GND +10V DC Same colour sequence

7 Installation and Operation 7 Relay outputs Relay output 1: Alarm Relay 1 (terminals 11, 12, 13) can be used to send an alarm signal to an external device. The signal output is a changeover relay which is closed between terminals 11 and 12 in idle position and otherwise closes between terminals 12 and 13. If the frequency converter has stopped due to a critical alarm, the relay will switch position and close between terminals 12 and 13. The relay is simultaneously opened between terminals 11 and 12. When the alarm is reset / acknowledged, the relay returns to its original position, closing between terminals 11 and 12. Max. 30VAC/24VDC/1A Alarm Relay 1 NC C NO NC Running Relay 2 C NO Relay output 2: Running indication Relay 2 (terminals 14, 15, 16) can be used to send an operating signal to an external device. The signal output is a changeover relay which is closed between terminals 14 and 15 in idle position and otherwise closes between terminals 15 and 16. When the frequency converter receives a start signal, the relay changes position, closing between terminals 15 and 16. The relay is simultaneously opened between terminals 14 and 15. When the start signal to frequency convert is removed, the relay returns to its starting position, closing between terminals 14 and Hand terminal (PAN-08) connection and functions The FWD-02 frequency converter can be connected to a PAN-08 hand terminal via Modbus RJ12 connector A. If a PAN-08 is connected, the hand terminal will act as master and the frequency converter as slave. Only one master at a time can be connected to the RJ12 connectors marked A and B. It is thus not possible to connect both a hand terminal to connector A and an active Modbus communication cable to connector B at the same time. PAN-08 has the following menu options: Status: Control and operating parameters for connected frequency converter Setup: Setting application parameters Alarm: Read-out of alarm log for connected frequency converter Modbus: Changing Modbus settings for frequency converter About: Read-out of software version no. and type for connected frequency converter Config: Changing frequency converter / motor settings

8 8 Installation and Operation 4. Functions Frequency controller can be controlled via: Analogue/digital (A/D) inputs Modbus RTU Local hand terminal PAN-08-0 Potentiometer The factory setting is Analogue/digital (A/D) control 4.1.

Speed 0% 100% 0V 9.5V Speed out Setpoint 100% 0% Up ramp Down ramp Setpoint Frequency controller can be controlled by external input signals. Before the frequency controller can be started, it must be given a start/stop signal. It is given by short-circuiting terminals GND and Din1. Speed is controlled by connecting the control signal (0-10V DC) to terminals 0-10V In and GND. Relation between control signal (0-10 V In) and speed see fig. The control signal regulates motor speed between the set minimum and maximum speeds (AC motor = Hz; PM motor = rpm) Time Time 4.2. Modbus control Frequency converter can be controlled via Modbus commands according to the Modbus protocol. Control of motor speed via Modbus communication is factory disabled. If the ffrequency converter is to be controlled via Modbus, Coil Stat Bit register 8 must be set to 0 = Modbus control. Other functions, such as alarm read-out and acknowledgement, are still possible via Modbus even though Modbus control is not activated. See more detailed description of Modbus in chapter 7. Modbus Switching frequency Switching frequency is crucial in determining the amount of audible acoustic noise emitted by the frequency converter. The higher the switching frequency, the less audible noise will be emitted by the frequency converter. At the same time, however, internal losses will be increased, reducing efficiency. The frequency converter can be set to operate constantly with a switching frequency of either 4 khz or 8 khz, or it can be set to change switching frequency automatically depending on motor speed (AUTO setting). Switching frequency (switching mode) is set via Modbus: Setting 4kHz = Constant 4kHz switching frequency Setting 8kHz = Constant 8kHz switching frequency Setting AUTO = Switching frequency is changed automatically: At motor speeds higher than 70% of rated speed, switching frequency is changed to 4 khz At motor speeds lower than 60% of rated speed, switching frequency is changed to 8 khz 4.4. Fire mode Fire mode designates a function in which the frequency converter is kept operating by an emergency program which disables the alarm monitor. Among other things, the function can be used in connection with smoke extraction from a burning property. When fire mode is activated, an extraction fan will continue to remove smoke from the property for as long as possible. In fire mode, the frequency converter is able to maintain operation for at least an hour even when the frequency converter and the fan motor are overheated (max. 70 C). In fire mode, the overheating protection built into the frequency converter is disabled and the motor is not stopped if communication is lost. In fire mode, the fan is not stopped in case of faults or other alarms from either the fan or the frequency converter. Speed is controlled to the actual setting, determined by an external 0-10V signal, a potentiometer or via Modbus from a Modbus master controller. Fire mode can be activated via Modbus.

9 Installation and Operation 9 5. Built-in protection If the temperature inside frequency converter exceeds +95 C, the frequency converter will attempt to reduce its internal heat generation by reducing motor speed (rpm). Frequency converter has built-in current limitation for the protection of motor and cables and cannot therefore supply more current than it is set to. In the event of lacking phase on the supply input, the frequency converter will reduce speed and activate a non-critical alarm. The frequency converter motor output terminals are short circuit protected against phase-to-phase short circuiting. 6. Alarms Frequency converter has a built-in alarm monitor, which monitors optimal fault-free operation and triggers an alarm if operating or performance problems are observed. Alarms are either Critical alarms or Non-critical alarms. Critical alarms stop the motor. Non-critical alarms reduce motor performance. The built-in alarm monitor stops the frequency converter. If the alarm situation passes, the alarm is automatically reset and frequency converter restarted. If the maximum number of restarts (5 times/60 min) is exceeded, the alarm must be reset manually. The alarm can be reset by means of a Modbus command. The alarm is automatically reset if the power is disconnected for longer than 60 seconds. Alarms can be read via Modbus, see Modbus protocol.

The LED is located on the underside of the frequency converter beside the entry for the mains cable. LED lights constantly green when mains voltage is connected. LED flashes green when Modbus communication is active. LED lights constantly red when at least one critical alarm is active- LED flashes red when at least one non-critical alarm is active. 7. Modbus 7.1. Introduction This protocol contains the Modbus addresses and registers which are available in the frequency converter. Modbus can access single addresses or several addresses simultaneously, either by reading or writing 1-bit or 16-bit values. A Modbus address contains either a 1-bit value or a 16-bit integer. Values in this protocol are to be changed at your own risk. It is your own responsibility that changing of values and settings does not cause any overload or damage to the product, motor or fan Modbus register types: Modbus Type Description Reference Coil Status (R/W) Discrete Output 0x Input Status (R) Discrete Input 1x Input Register (R) 16-bit Input Register 3x Holding Register (R/W) 16-bit Output Register 4x R=Read only, R/W = Read/Write LED

Modbus addressing Modbus addressing of frequency converter can be accomplished in three different ways. Via PC Tool by writing to Modbus Holding Register 4x0017 Via Hand Terminal, where frequency converter can be set to other Modbus addresses. Via the addressing pins of the A or B connectors see figure in chapter The addressing pins can be used to assign the frequency converter controls the address range: 0x36 (dec.54), 0x37 (dec.55), 0x38 (dec.56) and 0x39 (dec.57), see table below.

Maintenance Frequency converter is maintenance free under normal operating conditions and load profiles. The cooling fins must be kept free of dust, dirt and other foreign matter so that air can pass freely over them. Deposits of dust, dirt or other foreign matter on and between the cooling fins will prevent cooling of the frequency converter and thus impair performance. The cooling fins may become very hot. (Max. +95 C under normal operating conditions) Frequency converter cannot be repaired on site. Never attempt to repair a defective unit. Contact your supplier to obtain a replacement. Additional technical data are available on request from Fläkt Woods Oy.

14 14 Installation and Operation 9. Troubleshooting Before opening the frequency converter, the mains voltage must be disconnected for at least 3 minutes to ensure there is no risk of dangerous residual currents in electronic circuits or capacitors. If natural draught through the duct system cause the fan to rotate even though it has received no operating signal, there is a risk that the motor will induce voltage on the frequency converter motor terminals, making them dangerous to touch. Troubleshooting when frequency converter is controlled via A/D signals: Symptom Cause Action Lacking supply voltage Check voltage 400V in frequency controller terminals L1, L2 and L3 Check whether short-circuit protection has been activated. Check that the voltage supply to frequency converter has not been cut off by other components. Poor electrical connections Check electrical connections Wrong motor for frequency converter setup Check that the correct motor settings have been read into and stored in the frequency converter setup. Lacking operating signal A/D control: Short-circuit frequency controller terminals Din 1 (START) and GND Motor inoperative No 0-10 V DC control signal Check that 0-10 VDC signal is connected correctly to frequency controller terminals 0-10Vin and GND With potentiometer control : Check that the potentiometer is connected correctly to frequency controller terminals +10V dc, 0-10V In and GND. Active alarm Read out active alarms and remedy their cause. The motor has been stopped by the built-in motor protector 5 times because of overload or other alarm. Reset the alarm by short-circuiting frequency controller terminals DIn 2 and GND. The alarm can also be reset by disconnecting the power supply to the frequency controller and reconnecting it after approx. 60 seconds Defective frequency controller Replace frequency controller. Never attempt to repair a defective frequency controller. Contact your supplier for replacement/repair. Defective motor Replace motor Motor running in wrong direction Wrong phase sequence in motor cable Interchange two phase wires on the motor or the frequency converter terminal strip. Motor is noisier than acceptable Switching frequency too low Increase switching frequency 0 = Auto (factory setting), 1 = Low = 4 khz, 2 = High = 8 khz Raising the switching frequency increases energy losses in frequency controller. Switching frequency can be changed using the Hand Terminal. Frequency controller cuts out due to an alarm. At least one alarm active The alarm is re-activated after reset Use Hand Terminal to view the alarm and determine which alarm has stopped the controller/motor. Reset the alarm by short-circuiting frequency controller terminals DIn 2 and GND. The alarm can also be reset by disconnecting the power supply to the frequency controller and reconnecting it after approx. 60 seconds. Use Hand Terminal or PC Tool to view the alarm and determine which alarm has stopped the controller/motor. Remedy the cause of repeated alarm activation.
