2.3 Destination and use
The AZ 200 with non-contact electronic safety sensors is designed for
application in safety circuits and is used for monitoring the position of
movable safety guards. The integrated door detection sensor monitors
monitors the actuator position. The safety function consists of safely
switching off the safety outputs when the safety guard is opened and
maintaining the safe switched off condition of the safety outputs for as
long as the safety guard is open. The opening of the safety guard is
detected by the safety sensors.
LED functions
The safety switchgear signals the operational state as well as errors
through three coloured LED’s installed on the front side of the device.

4.1 General information for electrical connection
The electrical connection may only be carried out by autho-
rised personnel in a de-energised condition.
The power supply for the safety switch must provide protection against
must be used. The safety outputs can be directly integrated in the
safety circuit of the control system. For applications up to PL e / control
monitoring module of the same control category (refer to wiring examp-
with suitable interference suppression circuitry.
Requirements for the connected safety-monitoring module:
Dual-channel safety input
suitable for 2 p-type semi-conductor outputs
Test function
The safety-monitoring module must tolerate internal functional tests of
the sensors with cyclic switch-off of the sensor outputs for max. 2 ms
reduced by an active ohmic discharge of the cable. The safety-mo-
nitoring module does not need to have a cross-wire short monitoring
be disabled.
Cable
The cable entry is realised by a metric M20 x 1.5 gland. This gland
must be dimensioned by the user so that it is suitable for the cable
must be used.

The maximum cable length is 200 m (for ST2 M12 connectors approx.
20 m depending on the cable section used for an operating current of
2-

5 Operating principle and diagnostic functions
5.1 Safety switch with conventional diagnostic output
Mode of operation of the safety outputs
The opening of the safety guard causes the safety outputs to be disab-
led within the risk time.
Recommended suitable safety-monitoring modules
Operating principle of the electronic diagnostic output
The short-circuit proof diagnostic output can be used for central visua-
safety guard and the inserted condition of the actuator is indicated by
means of a 24V signal.
The diagnostic output is not a safety-related output!
Diagnostic outputs

5.2 Safety switch with serial diagnostic function
Safety switches with serial diagnostic cable have a serial input and
the series-wiring of the inputs and outputs.
Max. 31 safety switches can be wired in series. For the evaluation of the
-
nostic signals can be evaluated by means of a PLC.
The response data and the diagnostic data are automatically and
permanently written in an input byte of the PLC for each safety switch
