14 Diagnostics
The following section describes the LED indicators for gen-
eral states and error messages as well as possible causes
and remedies.
Function test/proof test
14.1 General states
14.2 Error Messages
Use the function test to check the safety func-
tion. To do this, request the safety function
once by pressing the emergency stop button,
for example. Check whether the safety func-
tion is running correctly by switching the de-
vice on again via the sensor circuits.

State Possible cause Remedy
ON OFF OFF The sensor circuit is actively
controlled, but no input LEDs
are lit up.
Interrupt in the sensor circuit
or faulty signal generator.
Check the sensor circuit/signal
generator. Then perform a
function test.
ON ON OFF The sensor circuit is active.
The safety circuit (K1 and K2)
is not picking up.
Internal error:
1. The diagnostic contact is
not working correctly.
2. An N/O contact is welded.
Internal error: perform a power
down reset with subsequent
function test. If the error oc-
curs again after the function
test, replace the device.
ON ON OFF The sensor circuit is active.
The safety circuit (K1 and K2)
is not picking up.
Error in the sensor circuit. Check the sensor circuit. Then
perform a function test. If the
error occurs again after the
function test, replace the
device.
OFF OFF OFF The sensor circuit is active. 1. No supply voltage at A1/A
2. Over- or undervoltage at
A1
Check the supply voltage.
