Switching on
❚
K2/K4 must be switched on
before or at the same time
as K1/K3!
Switching off
❚
Normal - AC switching
-
K2/K4 remain closed
-
K1/K3 open
❚
Emergency stop - DC switching
-
K1/K3 and K2/K4 are opened at the same time

Bridge/half-wave rectifier (optional)
BEG-561-
-
The bridge/half-wave rectifiers are used to supply electromagnetic DC spring-applied brakes which are ap-
proved for the use with such rectifiers. Other use is only permitted with the approval of INTORQ.
Once a set over-excitation time has elapsed, the bridge/half-wave rectifiers switch over from bridge rectifi-
cation to half-wave rectification.
NOTICE
