VB 230/400-25

The closing of the mains contactor starts the following sequence:

1. The potential-free contact X11, X12 will be closed (control of the star contactor).
2. After a period of 6s X11, X12 will be opened.
3. After a delay of 60ms the potential-free contact X12, X13 will be closed (control of the delta 

contactor).

The opening of the mains contactor starts the following sequence:

1. The contact X12, X13 will be opened (delta contactor will be switched off).
2. After  the  drop  of  the  remanent  voltage,  X11,  X12  will  be  closed  (control  of  the  star 

contactor).

3. When the contact bounce time is over, the braking current will flow for approx. 1.5s after 

the motor standstill.

In  the  case  of  star-delta  starting,  even  if  not  implemented  via  the  VersiBrake  device,  the  star 
contactor should be controlled via the contact on the terminals 11 and 12 (option „D“) to initiate 
braking.  Thus,  the  motor  windings  are  interconnnected  in  time  before  the  actual  braking 
operation.

Note:

To ensure that, in the case of external star-delta control, the starting 
operation is not influenced by the VersiBrake, a break contact of the motor 
contactor K1 has to be connected in series before the terminals 11 and 12.

10.4 Option „S“ – Standstill signaling relay

This option makes the motor standstill signal available on a potential-free contact (X16, X17).
Possible states on X16, X17:

Warning note:

Prior to using the standstill signaling contact for safety-directed purposes, it 
is necessary to subject the application to a risk assessment according to 

 

EN 1050 (ISO 14121).
