Start-up test
After pressing the reset button or after interrupting the power supply for a few seconds, a
start-up test takes place, which should be monitored visually if possible.
It can be verified using the LEDs as follows:
– the fault indication contact (SM 1) closes at ESR32 (or opens at ESR31C)
– the “SYSTEM ERROR” red LED lights up for one second
– then for one second the “SENSOR ERROR” red LED lights up
– then for one second the two “SAFETY STOP” yellow LEDs light up
– then both “SAFETY STOP yellow LEDs light up for one second and the “POWER” green LED
flashes
– afterwards the “POWER” green LED lights up and indicates the operational state and the
safety output relays (SR 1, SR 2) pick up.

Maintenance and troubleshooting
After the device has been correctly mounted and installed and if the technical data are ob-
served, it will operate without any maintenance being required. The safety system must nev-
ertheless be checked at regular intervals for correct functioning (every month or in accord-
ance with higher level regulations). The sensors and feed lines must also be checked for
mechanical damage.
If functionality is not provided after wiring according to the circuit diagram and if
both yellow or red LEDs light up, proceed as follows:
1. ESR31C:
Press the reset button (min. 1 sec.) or restart ESR31C, ESR32 device.
2.
Check all sensors for actuation or damage.
3.
Check sensor resistances (typically 8.2 kΩ); for this measurement the sensor must not be
connected to terminals 22/32 (5/8) and 24/34 (7/9).
4.
For commissioning again, see chapter 7.
There is a unit fault if both red LEDs continue to light up afterwards.
Return the device for checking.
If yellow or red LEDs light up in addition to the green LED
Return the device for checking.

Commissioning
a) Check wiring. Are F1 and F2 present with max. 2 A slow blow?
b) In order to determine the resistance values of the sensors, the switching device must not
be plugged into the socket. Measure the resistance values at the socket (sensor 1:
terminal 22/32 (5/8), sensor 2: terminal 24/34 (7/9). The resistance values must each be
between 7.5 kΩ and 9 kΩ (typically 8.2 kΩ).
c) Check the voltage data on the switching device’s type plate.
d) Switch on the switching device.
The start-up test is started, see chapter 8. After a successful test, the “POWER” LED
lights up green. The safety outputs (SR1, SR2) are closed. The fault indication contact
(SM 1) is open at the ESR31C switching device and closed at the ESR32 switching device.
e) Operate sensor 1.
Both “SAFETY STOP” yellow LEDs light up, both safety output relays (SR1, SR2) open.
The fault indication contact (SM1) remains unchanged. The ESR31C switching device
locks and must be restarted with the “RESET” button. If the sensor is not actuated, the
“SAFETY STOP” LEDs for the ESR32 switching devices switch off again and the safety
outputs (SR1, SR2) close. The fault indication contact (SM1) remains unchanged.
f) Operate the sensor 1 at various points.
The ESR3 switching device must behave as described under e).
g) Interrupt the connection between the ESR3 switching device and sensor 1.
The “SENSOR ERROR” and “SYSTEM ERROR” red LEDs light up, the safety output
relays (SR 1, SR 2) open. The fault indication contact (SM 1) closes at the ESR31C
switching device and opens at the ESR32 switching device.
h) Close the connection between the ESR3 switching device and sensor 1.
The ESR3 switching devices remain locked, the “SENSOR ERROR” and
“SYSTEM ERROR” red LEDs light up.
i) ESR31C switching device: Press the “RESET” button or switch off the switching device
and switch it on again after a few seconds.
ESR32 switching device: Switch off the switching device and switch it on again after a
few seconds.
The start-up test d) is started again.
j) Repeat points e) to i) for sensor 2.
