Activate Emergency power-off module
Before the Compax3 can be placed in operation, the Emergency Power-off module
must be activated by a pulse to Input S33/S34.
Prerequisite:

Safety door closed: only in this case the safety door monitor enables the emer-
gency power off module via two channels
K1 energized via PLC (feedback channel 1: motor not energized)
The feedback contact of all Compax3 devices must be closed (channel 2).
If S33 & S34 of the Emergency power-off module are briefly connected (pulse) the
contacts will be closed (between 13 & 14 and between 57 & 58).
Energize Compax3 (Motor and power output stage)
The PLC enables the Compax3 devices by means of the control word and the
Emergency power-off module enables the Compax3 devices by means of the

acknowledged/reset)
The motors are energized with current.

functioning via two channels.
