Operating instructions
5. Start-Up
During the examination, you must work on live equipment. The
inspections must only be performed by professionals while observing
the specified safety measures.
Caution!
Due to automatic restart after a power failure, the speed dial switch
should be in the “0” position before reconnecting to the mains!
The following examinations must be performed prior to start-up:
G
Have all of the equipment components been connected properly in
accordance with the valid connection diagrams?
G
Has the earth wire (PE) been connected properly for all equipment com-
ponents?
G
Have all of the thermal contacts for the fan motors been connected
properly? (All of the thermal contacts for a fan group been switched in
series). If a malfunction occurs and it cannot be eliminated, the input
voltage, the fan motor and the thermal contacts must be checked!
G
Has the supply voltage (400V) been provided between terminals L1, L2
and L3?
G
Has the room sensor been connected properly? If the operating mode
selector switch is not in the "Manual" position, then the room sensor
cable is interrupted or reverse poled meaning that the equipment is not
working. If the sensor cable short circuits, the equipment is in
continuous mode. No fan stage can be selected with voltage reversal in
automatic mode. The room sensor has been calibrated by the
manufacturer. However, if necessary, an offset value can be entered. The
potentiometer (sensor offset) required for this can be found behind the
front panel under the LED.
Caution! The equipment may only be started up once all of the line
components have been installed properly and all connections have been
checked for correctness!
