Non-Contact Safety Switches CES/CEM
Function test CES-A-AEA... (self-test)
On electromechanical safety switches or magnetic switches, the function test can be performed by cyclically opening the safety guard.
From safety category 2, according to IEC/EN 60204-1 : 1997 (sec. 9.4.2.4), a function test must be performed on the entire safety
system on start-up or after defined intervals.
The testing of the internal function of the safety switch CES is not necessary because the device monitors itself in real time. Wear on
an output contact (relay output) is detected by the device at the latest the next time the safety guard is opened. A short circuit in the
output cable is not detected by the device.
In addition, the entire safety circuit can be tested without opening the safety guard. For this purpose the opening of the safety guard
can be simulated by applying DC 24 V to the test input.
The safety outputs are switched off, enabling testing of the complete safety circuit. The diagnostic output DIA of the evaluation unit is
also set HIGH as a monitoring function.
When the test input is reset, the evaluation unit resets the diagnostic output DIA to LOW, the red LED switches off and normal operation
continues. This permits self-testing of the safety system without opening the safety guard.

Function test active (TST input = 24 V)
Component failure inside the device or actuator in
the operating distance for less than 0.5 s or
actuator CES-A-BMB in the inadmissible range
Configuration fault:
Teach-in operation must be performed again
Possible causes:
- State change during the teach-in operation
- None of the DIP switches in ON position
- DIP switch setting and
- DIP switch setting has been changed without
- The teach-in jumper (J1, J2) was fitted with power
- Connected feedback loop (Y1,Y2) present,
- 24 V signal present at the start button input (S)
