VC II 230/400-3...15

Check of the start key

A defective or charred key causes a fault. 

 

The motor cannot be started anymore. 

 

Reset after fault recovery and mains reset.

Exceeding the permissible max. braking time

If, after the max. braking time is over, no motor standstill is detected, this leads to a fault (red 
„fault“-LED is illuminated).

When restarting the motor, this fault will be reset.

If this fault occurs 3 times in succession during an operation phase, the motor cannot be started 
anymore. 

 

Reset after fault recovery and mains reset.

Possible fault causes:

the adjusted braking current is too small

despite the fact that the maximum braking current is adjusted, the motor or the centrifugal 
mass on the motor is too large

In the latter case, an incorrect device rating was chosen. A device with a higher braking current or 
a device featuring a longer braking time has to be used, in so far as this is permissible for safety 
and functional reasons. 

7.4

Option „B“ – Wide-voltage-range

With this option, it is possible to use VersiComb II-devices within a mains voltage range from 
200...480V.

This requires a device supply voltage of 24V AC or 230V AC which has to be connected to the 
terminals 3, 4.

If VersiComb II is used as a wide-voltage-range device, the control voltage has to be in the same 
range as the supply voltage.

Note:

In the case of standard devices this option is not available, even if the 
terminals are present.

The requested option and the device supply voltage to be used have to be 
expressly indicated when placing the order.

Device supply voltage

 - 24V AC

 - 230V AC

Control voltage

 - 24V DC

 In the case of a control voltage of 24VAC, 

a special device will be required.

 - 230V AC
