Electrical connection
For use and operation as per the requirements of
(UL), an isolating transformer or a power supply
with secondary overcurrent protection (3 A) must be
used.
The safety switch is connected to the bus system
with a 4-core connecting cable with M12 plug
connector via a passive AS-Interface distribution box
with yellow and black AS-Interface cable.

Setup
f Setting the AS-Interface address
The address can be set prior to or after assembly.
The AS-Interface address of the safety switch is set
using an AS-Interface programming device. Addresses
1 to 31 are valid.
The unit is programmed by connecting the program-
ming device to the M12 plug connector on the safety
switch with an AS-Interface programming device.
Address 0 is the default setting on delivery (the AS-
Interface LED
Fault! is lit during operation).
f Configuration in the AS-Interface safety monitor
(see operating instructions for the AS-Interface safety
monitor and status table)
The safety switch is configured in the AS-Interface
safety monitor with the AS-Interface address set as
follows, for example:
f Two-channel dependent
f With start-up test
f Synchronization time = typ. 3 s
In this operating mode, the safety guard must be
opened each time prior to restarting in order to per-
form the start-up test.
It is possible to skip the start-up test.
f It is not possible to switch off the guard locking
solenoid by means of the monitor alone.
The control system (PLC) must therefore switch off
the guard locking solenoid in locked position via
AS-Interface output D0 = 0 in order to re-establish
the switch-on conditions for the first OSSD.
f Status signals (not relevant to safety)
The state of the door monitoring contacts SK can
also be polled by the control system (PLC) (refer to
the operating instructions for the AS-Interface safety
monitor).
f LED indicators
The AS-Interface bus status is indicated by two LEDs
(Power, Fault).
Two additional LEDs can be connected via the AS-
Interface bus, e.g. to indicate the status signals (see
Status signals and Technical data).
Functional check
Warning! Danger of fatal injury as a result of faults
in installation and functional check.
Before carrying out the functional check, make
sure that there are no persons in the danger
area. Observe the valid accident prevention
regulations.
After installation and any fault, the safety function must
be fully checked. Proceed as follows:
f Mechanical function test
The actuator must slide easily into the actuating head.
Close the safety guard several times to check the
function.
f Electrical function test
1. Switch on operating voltage.
2. Close all safety guards.
Guard locking by solenoid force ¨ Activate
guard locking.
f The machine must not start automatically.
f It must not be possible to open the safety guard.
3. Enable operation in the control system.
f It must not be possible to deactivate the guard
locking as long as operation is enabled.
4. Disable operation in the control system and
deactivate guard locking.
f The safety guard must remain locked until there is
no longer any risk of injury.
f It must not be possible to start the machine as long
as the guard locking is deactivated.
Repeat steps 2 - 4 for each safety guard.
Inspection and service
If damage or wear is found, the complete switch
and actuator assembly must be replaced.
Replacement of individual parts or assemblies,
especially of the actuating head, is not permitted!
Note: The year of manufacture can be seen in the
bottom, right corner of the rating plate.
No servicing is required, but regular inspection of
the following is necessary to ensure trouble-free long-
term operation:
f correct switching function
f secure mounting of components
f dirt and wear
f loose plug connectors.
Exclusion of liability under the following
circumstances
f incorrect use
f non-compliance with safety regulations
f installation and electrical connection not performed
by authorized personnel
f failure to perform functional checks.
