6.6.
Diagnostics monitoring output/bit OI
The diagnostic output is switched on in the event of a fault (switch-on condition as for DIA LED).
6.7.
Guard lock monitoring output/bit OL
The guard lock monitoring output is switched on when guard locking is active.
6.8.
Safety output status output/bit OM
Evaluation via the BR evaluation unit.
This status output is switched on if the safety outputs of all preceding devices in the series connection are switched on.
6.9.
Locking element status output/bit OLS
Evaluation via the BR evaluation unit.
This status output is switched on if the locking element is stuck and guard locking therefore cannot be activated/deactivated.
6.10. Guard locking on version CTM-CBI
(guard locking by spring force and released by power-ON)
Activating guard locking:
close guard; no voltage at control input IMP or data bit switched off.
Releasing guard locking:
apply voltage to control input IMP or switch on data bit.
The spring-operated guard locking functions in accordance with the closed-circuit current principle. If the voltage is interrupted
at the solenoid, the guard locking remains active and the guard cannot be opened directly.
If the guard is open when the power supply is interrupted and is then closed, guard locking remains released. This prevents
people from being locked in unintentionally.
Important!
Malfunctions due to incorrect use.
Ì
The actuator must not be under tensile stress during release.
Ì
Very strong jolts or vibration can cause the guard locking state to change unintentionally. This gen-
erally applies when the switch is electrically isolated.
-The switch must not be used as a mechanical end stop.
-In case of heavy doors, ensure that the impact energy is cushioned on closing.
