Operating Instructions

Transponder-Coded Safety Switch CTM-LBI-BP/BR

(translation of the original operating instructions) 2525462-03-06/21

6.3.5. 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.

6.3.6. 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

10.

Using communication data on page 26

If no BR/IO-Link Gateway is connected, this output behaves like a monitoring output.

6.4.

Guard locking

Important!

Malfunctions due to incorrect use.

The actuator must not be under tensile stress during release.

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.

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 remains

released. This prevents people from being locked in unintentionally.

6.4.1. Guard locking on version CTM-LBI and control via control input IMP

(guard locking actuated by spring force and released by power-ON)

Activating guard locking:

close guard; no voltage at control input IMP.

Releasing guard locking:

apply voltage to control input IMP.

6.4.2. Guard locking on version CTM-LBI and control via IO-Link communication

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)!

Activating guard locking:

guard locking actuated by spring force and controlled by bit

(bit

= 0).

Releasing guard locking:

guard locking released by the device’s operating voltage and deactivated by bit

(bit

= 1).
