6.2.3. Door position2 signal OT
The door position2 signal is present if the actuator is completely inserted in the switch head and the guard locking can be
activated. In normal ambient conditions, the signal OT is sent after the signal OD as an additional door monitoring contact.
The signal is also present if the guard locking is active (see chapter 6.4. Switching states on page 12).
6.2.4. Diagnostic signal OI
The diagnostic signal is present if there is an error (switch-on condition as for DIA LED).
6.2.5. Escape release signal OER
The escape release signal is present if the device has been released manually or if manual release prevents activation
of guard locking (see chapter 7. Manual release on page 13). The signal is reset when the guard locking control state
matches the guard locking state.
6.2.6. Status signal OM
The status signal is present if the device’s safety outputs are switched.
6.2.7. Locking element signal OLS
The locking element signal is present if the locking element is stuck and guard locking cannot be released. The signal is
reset as soon as the actuator is no longer under tensile stress or the locking element is no longer jammed.
6.2.8. Communication connection C
A monitoring output with the sufx 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 nd an overview of the communication data in chapter12.
Using communication data on page 29.
If no BR/IO-Link Gateway is connected, this output behaves like a monitoring output.
6.3. Guard locking
(guard locking actuated by spring force and released by power-ON)
Important!
Malfunctions due to incorrect use.
Ì The actuator must not be under tensile stress during release.
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.
Important!
If the guard is open when the power supply is interrupted and is then closed, guard locking is activated.
This can lead to persons being locked in unintentionally.
The actuator cannot be pulled out of the switch and the guard is locked as long as the guard locking pin is extended.
Guard locking cannot be released as long as no electronics operating voltage is present at the device. When electronics
operating voltage is applied to the device and voltage is applied to the guard locking solenoid, the locking pin is retracted
and the actuator is released. The guard can be opened.
Activating guard locking: close guard; no voltage at the solenoid.
Releasing guard locking: apply electronics operating voltage and voltage to the solenoid.
