Operating Instructions
Transponder-Coded Safety Switch CTM-C2-BP/BR-FLX

(translation of the original operating instructions) MAN20001574-01-09/22
6.2.3. Guard locking signal OL
The guard locking signal is present if the guard locking is active.
6.2.4. Status signal OM
The status signal is present if the device’s safety outputs are switched.
6.2.5. Locking element signal OLS
The locking element signal is present if the locking element is stuck and it is therefore not possible to activate/deactivate
guard locking. The signal is reset as soon as the actuator is no longer under tensile stress or the locking element is no
longer jammed.
6.2.6. Communication connection C
A monitoring output with the suffix C has the additional function of providing a communication connection to a BR/IO-Link
Gateway. The switch delivers cyclical and acyclical data. You will find an overview of the communication data in chapter
Using communication data on page 24
.
If no BR/IO-Link Gateway is connected, this output behaves like a monitoring output.
6.3.
Guard locking
Important!
Malfunctions due to incorrect use.
Ì
The actuator must not be under tensile stress during release.
The magnetically actuated guard locking operates according to the open-circuit current principle. If the voltage is interrupted
at the solenoid, the guard locking is released and the guard can be opened directly.
The guard can be opened as long as no voltage is applied to the guard locking solenoid.
If a voltage is applied to the guard locking solenoid, the guard locking pin is held in the extended position and the guard is
locked.
Important!
Use as guard locking for personnel protection is possible only in special cases, after strict assessment
of the accident risk (see EN ISO 14119:2013, section 5.7.1).
6.3.1. Guard locking on version CTM-C2 and control via control input IMP
(guard locking actuated by power-ON and released by spring force)
Activating guard locking:
close guard, apply voltage to control input IMP.
Releasing guard locking:
interrupt voltage at control input IMP.
6.3.2. Guard locking on version CTM-C2 and control via IO-Link communication
Activating guard locking:
guard locking powered by the device’s operating voltage and controlled by bit
CL
(bit
CL
= 1).
Releasing guard locking:
guard locking released by spring force and deactivated by bit
CL
(bit
CL
= 0).
