6. Function
The safety switch monitors the position of movable guards. The safety outputs are switched on/off when the actuator is
moved into/out of the actuating range.
The system consists of the following components: coded actuator (transponder) 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 tam-
pering. The system thus possesses a high coding level.
Ì
Devices with multicode evaluation
: Unlike systems with unicode evaluation, on multicode devices a specific code
is not requested but instead it is only checked whether the actuator is of a type that can be detected by the system
(multicode evaluation). 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 distances are reached,
power is supplied to the actuator by the switch and data are transferred.
When a permissible code is detected, the safety outputs FO1A and FO1B 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. Limit-range monitoring
The device detects if the actuator drifts out of the actuating range of the switch over time. The STATE LED or the limit range
signal OW indicates that the actuator is in the limit range (see chapter
14.2. Status messages on page 24
). Readjusting
the door can prevent the actuator from drifting further out of the actuating range.
6.2. Door position monitoring output OD
The device features a monitoring output for the door position signal OD. Depending on the application, the signal is available
at the monitoring output or as a status bit. The status bit is evaluated via the BR/IO-Link Gateway. If no BR/IO-Link Gateway
is connected, this output behaves like a monitoring output.
The door position signal OD is present when a valid actuator is detected in the actuating range and the guard is closed.
6.3. Communication connection C
When the device is connected to a BR/IO-Link Gateway, the monitoring output functions as a communication connection.
The switch delivers cyclical and acyclical data. You will find an overview of the communication data in the chapter
Overview of the communication data on page 20
.
6.4. Switching states
The detailed switching states for your switch can be found in the chapter
14. Status and error messages on page 24.
All safety outputs, signals and display LEDs are described there.
