6. Function
The safety switch monitors the position of movable safety guards. The safety outputs are switched on/off when the actuator
moves into/out of the operating distance.
The system consists of the following components: coded actuator (transponder) and switch.
Whether the complete actuator code of the device is taught in (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 tam-
pering. The system thereby possesses a high coding level.
Ì
Devices with multicode evaluation
: Unlike systems with unique code detection, on multicode devices a specific code
is not polled 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 (unique
code detection). The system possesses a low coding level.
When the safety guard is closed, the actuator is moved towards the safety switch. When the switch-on distance is reached,
power is supplied to the actuator via the switch and data transfer takes place.
If a permissible code is detected, the safety outputs are switched on.
The safety outputs are switched off when the safety 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 failures 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 operating distance.
6.2. Diagnostics output
The diagnostics output is switched on in the event of a fault (switch-on condition as for DIA LED).
6.3. Limit-range monitoring
If the safety door with the actuator should settle over time, the actuator can drift out of the read head operating distance.
The device recognizes this situation and indicates that the actuator is in the limit range by flashing the STATE LED. This
allows the safety door to be readjusted in time. Also see chapter
5. System status table on page 18

6.4. Switching states
The detailed switching states for your switch can be found in the system status table. All safety outputs, monitoring outputs
and indicating LEDs are described there.
