We reserve the right to make changes without prior notice. Installation and maintenance Control equipment External placement of control unit When cables are routed from an external control unit, terminal blocks 15–34 should be routed in screened multiconductor cable of their own, which should be kept separate from other signals. The screen should only be earthed in the external cabinet, and should be left unconnected in the junction box to prevent earth currents in the screen. Signals 1–14 and 35–44 can be placed together in a multiconductor cable. Minimum cross section of the multiconductor cable to the external control unit: 0.75 mm2. The control unit must be located at a maximum distance of 100 m. The plint interface solution is designed so that the control unit can be installed either in the control panel or in an external cabinet. When the control unit is installed and powered externally, the jumper between PE and G0 must be removed on the connection board, see page 6 pos 13. In the external cabinet, G0 must be connected to earth to prevent G0 from floating relative to earth. In addition, the jumpers between terminal blocks INPUT and LOCAL, page 6 pos. 12 and 20, should be disconnected and replaced with signals G and G0 from the external cabinet to the INPUT terminal block. Extended multicable When Twin Wheel and preheater are ordered for eQ, these functions should be connected to the connection board indicated above. See table on pages 10–11.

Installation and maintenance StyrControl och equipment reglerutrustning (only for Norway) Electrical connections for Norway without transformer, (3x230 VAC) The power unit for air handling units intended for a 3x230 VAC power supply is different in a number of ways to that for a 3x400 VAC power supply. They must not be mixed up. The unit is connected in the same way as on page 6, except the terminal block 3b on page 6 is internally protected by a 10A fuse. Phases L1-L2 supply the control panel through control switches. In this case the blue conductor in the system is not the neutral conductor but phase L2. NOTE!

Installation and maintenance Control equipment Connecting sensors and accessories The cellular plastic, which is semi-elastic, will slowly adapt to the shape of the cables thus sealing the lead-in. The electrician in charge must ensure that the installation has been done correctly. The following paragraphs provide information about how to install and connect the various sensors and accessories. External components can be easily connected to the eQ unit through a quick connector or wires to a screw terminal block in the control cabinet. Then the cable is routed through the cellular plastic strip on the air handling unit and secured to the adjacent mounting rail. Remember to place the cables with a suitable diameter. When all cables have been connected to the terminal block, fit the control panel cover and secure it using the screws supplied. Fig. 4 Tip: The frame of the control panel can be turned so that the mounting rail faces downwards on outdoor units and upwards on indoor units where the incoming supply comes via a ceiling mounted cable ladder. Connecting the lighting The light fittings are connected in the air handling unit at the factory, and cable is ready routed through the panels to the outside. The power supply and connection of the lighting for the air handling unit must be carried out by a qualified electrician. The power supply for the lighting comes from a lighting switch/junction box for the air han- Fläkt Woods 9028 GB 2013.05 dling unit which is either factory fitted or supplied separately with the unit. The lighting circuit must be supplied with overcurrent protection in accordance with SS-EN 60204-1.

To obtain the correct measured values, the heat-conducting paste supplied must be applied to the return line when the contact sensor is secured onto the return line using cable ties. The supply air temperature sensor (GT1) should be fitted in the supply air duct, approximately 1.5 m from any duct heaters, to give stable measurement values. The outdoor temperature sensor (GT3) for installation on the facade, is installed centrally on an outside wall, at least 2.5 m from the ground, on the building in which the temperature is to be controlled. The sensor should not be exposed to morning sun or installed above a window, door or other heat sources. Install the sensor on a wall that faces north if possible. The room temperature sensor (GT2) is intended for placement on an interior wall in the room where the temperature is to be controlled.

Installation and maintenance Control equipment Questions and answers Pressure/Flow The display shows that the flow/pressure is not zero, despite the unit being switched off. Are the sensors faulty? • The sensors must be zero calibrated on delivery as well as annually. You can read how this is done on the sensor data sheet as well as in this document in the section Pressure/Flow Sensor DPT1000/3000. • Is the damper closed? There might be an air flow through the air handling unit. Temperature The controller cannot maintain the set temperature. What can be wrong? • Is the heating coil/cooling coil dimensioned for the prevailing outdoor temperature? • Investigate whether the water temperature to the heaters is sufficiently high/low? • Investigate whether there is a power supply to the electric heater. • Ensure that there are no windows or doors open. The desired pressure setpoint/flow setpoint cannot be achieved. Why? • External pressure drop too high. • A pressure hose may have become disconnected. Stop the unit, open the hatches, look and rectify if necessary. • The cap on an unused red measurement nipple (located on the door pillar of the air handling unit) may have come off. Reinstall the cap. • Badly configured sensor. Open the cover of the dif ferential pressure sensors. Different measurement ranges can be set using the jumpers. When differential pressure sensors are factory fitted, the sensors are con figured at the factory. If the differential pressure sen sors are enclosed separately with the unit (pressure control) they are set to 500 Pa and may need to be adjusted to improve performance. Remember that the measurement range you set on the differential pres sure sensors must also be entered on the controller. • The sensors have not been calibrated during the last year. Zero calibrate them! You can read how this is done on the sensor data sheet as well as in this docu ment in the section Pressure Sensor/Flow Transmitter, page 12. • The sensor measurement range has not been entered on the controller. Compare the jumper settings on the differential pres sure sensors with the set measurement range on the controller. The electric heater is tripped by the automatic thermal overload protection. How do I rectify the fault? • Air supply temperature is too high. Reduce the set point or increase the flow. After the cover has been fitted on the control panel several gaps are visible in the cellular plastic strip. Is the lead-in really sealed? • If the gaps still remain after a few days, the cables should be moved sideways slightly. Why is there no main circuit breaker? • The unit must be equipped with an external load inter rupter on the incoming supply. Diagnostic testing of the flow indicates that the flow displayed has not been achieved. • See the point above. Why does the current flow setpoint/pressure setpoint deviate from the setpoint values entered under “Flow controller” and “Pressure controller” respectively? • The set point values entered can deviate from the current values if fan compensation is activated.
