Electrical connection
The devices are tested according to the require-
ments of UL508.
Tests regarding EMC and FMEA or tests for use in
safety circuits are performed by TÜV Süd.
This device is intended to be used and applied with
a Class 2 power source.
Alternative solutions must comply with the follow-
ing requirements:
This device shall be used with a suitable isolating
source in conjunction with a fuse in accordance

Addressing
The device can be addressed via the AS-Interface
safety bus.
Configuration in the AS-Interface
safety monitor
(see operating instructions for the AS-Interface
safety monitor)
The safety switch is configured in the AS-Interface
safety monitor with the AS-Interface address set as
follows, for example:
Dual-channel dependent
f
With start-up test
f
Synchronization time = 3 seconds
f
In this operating mode, the guard must be opened
each time prior to restarting in order to perform
the start-up test.
AS-Interface status messages
(only for CMS-R-AZA...AS1)
A dual LED (red/green) displays the colors red, green
and yellow. The following table provides assistance
with troubleshooting.
State of ASI LED
Explanation
Green
Normal operation
No data exchange between
master and slave
Cause:
Red
- Master in STOP mode
- Slave not in LPS
- Slave with wrong IO/ID
- Reset on slave active
No data exchange between
red/yellow alternately flashing
master and slave
Cause: slave address=0
red/green alternately flashing Device fault in the slave.
Contact EUCHNER.
Red flashing
An additional function LED can be connected via the
AS-Interface bus, e.g. to indicate the door state. The
LED is connected as an output to the AS-Interface
bus via bit D1.
Function test
WARNING
Fatal injury due to faults during the function test.
Before carrying out the function test, make sure
that there are no persons in the danger zone.
Observe the valid accident prevention regula-
f
tions.
Check the device for correct function after
f
installation and after every fault.
Proceed as follows:
Electrical function test
1. Switch on operating voltage.
2. Close all guards.
The machine must not start automatically.
¨
3. Start the machine function.
4. Open the guard.
The machine must switch off and it must not be
¨
3
possible to start it as long as the guard is open.
Repeat steps 2 - 4 for each guard.

Service and inspection
Remove iron swarf from the read head and actuator
at regular intervals.
Use only solvent-free cleaning agents for cleaning
the read heads and actuators.
Regular inspection of the following is necessary
to ensure trouble-free long-term operation:
Correct switching function
f
Secure mounting of components
f
loose connections.
f
In the event of damage or wear, the damaged
system component must be replaced.
Exclusion of liability under the
following circumstances:
Incorrect use
f
Non-compliance with safety regulations
f
Installation and electrical connection not per-
f
formed by authorized personnel
failure to perform functional checks.
