Example for NT compressor:
If the compressor control is parametrised as combined control and the fan control as speed control, the NT /
MP motor cutout 1 / FC Fault input (digital input 4) monitors the fault signal output of the frequency converter for
the compressor control and must be wired accordingly. As a result, the fault signal output of the FC / speed
controller for the fans cannot be monitored.
B. Fan combined control
An additional digital input is always required for the monitoring of the FC / speed controller for fan combined
control. The digital input "Motor protection fan" is used which always follows the last used motor protection
input. For this type of control, the message text for this input is automatically set to
Speed controller HP .
Example: number of fans n = 3
Number (n) of the digital inputs for motor protection fan = 3: M1 ... M3
Digital input for monitoring the FC / speed controller (n+1): 4th input (M4)
This fault signal is active when there is no voltage at the NT / MP motor cutout 1 / FC Fault input, i.e.
the frequency converter must be parametrised and connected so that 230 V AC is present at the digital
input 4 of the pack controller in the good state.

The fault signal is active when there is no voltage at the "Motor protection fan" (n+1) input, i.e. the FC /
speed controller must be parametrised and connected so that 230 V AC is applied to this pack
controller input in the good state. 
