Switches and buttons:
1 N/C (S4, S5) per
device:
Guide Device to a currentless state
S6:
closed when the safety door is closed
S2:
Activate safety switching device
Module UET410-MU3T5 modulates regularly test switching signals (OSSD) on
outputs Q3 and Q4.
We recommend to use a filter > 3 ms for signal Q3 in the PLC.

Safe torque off basic function
Compax3 devices disabled by:
Channel 1: Energize input to “0” by safety switching device output Q3
Channel 2: Enable input ENAin to “0” by safety switching device output Q4
Activate safety switching device
Before the Compax3 can be placed into operation, the safety switching device
must be activated by a pulse to Input S2.
Prerequisite:
S2 closed
Safety door closed
K1 and K2 energized
K1: receives current if Compax3 Device 1 is currentless (output = "1" in
currentless state) = Channel 1 feedback
K2: receives current if Compax3 device 2 is currentless (output = “1” in the
currentless state) = channel 1 feedback
The feedback contact of all Compax3 devices must be closed (channel 2).
Energize Compax3 (Motor and power output stage)
With the safety switching device, the Compax3 devices are enabled via the
energize input and the Enable input ENAin. (If an error is still present in the
Compax3, it must be acknowledged - the ackn function depends on the Compax3
device type)
The motors are energized with current.
Summary: Compax3 is only energized if the feedback functions are capable of
functioning via two channels.
Caution!
