6. Function
The safety switch monitors the position of movable guards. The safety outputs are switched on/off when the actuator is
moved to/removed from the actuating range.
The system consists of the following components: coded actuator (transponder with high coding level) and switch.
Whether the device learns the complete actuator code (unicode) or not (multicode) depends on the respective version.
Ì Devices with unicode evaluation: The actuator must be assigned to the safety switch by a teach-in operation so that it
is detected by the system. This unambiguous assignment ensures a particularly high level of protection against tampering.
The system thus possesses a high coding level.
Ì Devices with multicode evaluation: Unlike systems with unicode evaluation, on multicode devices a specic code is
not requested but instead it is only checked whether the actuator is of a type that can be detected by the system (multi-
code detection). There is no exact comparison of the actuator code with the taught-in code in the safety switch (unicode
evaluation). The system possesses a low coding level.
When the guard is closed, the actuator is moved towards the safety switch. When the operating distance is reached, power
is supplied to the actuator by the switch and data are transferred.
If a permissible code is detected, the safety outputs are switched on.
The safety outputs are switched off when the guard is opened.
In the event of a fault in the safety switch, the safety outputs are switched off and the DIA LED illuminates red. The occurrence
of faults is detected at the latest on the next demand to close the safety outputs (e.g. on starting).
6.1. Door monitoring output
The door monitoring output is switched on as soon as a valid actuator is detected in the actuating range.
6.2. Switching states
The detailed switching states for your switch can be found in the system status table. All safety outputs, monitoring outputs
and display LEDs are described there.
Guard closed
(actuator in the actuating range and permissible
code detected)
Guard open
(actuator not in the actuating range)
Safety outputs LA and LB on off
Monitoring output OUT on off
