- If the safety input remains free:
Ensure that the contact makers of this safety input are bridged.
10 Electrical connection
- Electrical connection is only permitted in a voltage-free state.
- Make sure that the details described in the technical specifications are al-
ways complied with.
- Measures to improve the equipment’s immunity to interference from line-
conducted and radiated high frequency interference are to be taken
(DIN EN 60204-1:2007-06, para 4.4.2).
When connecting the sensor, the sensor power supply voltage (+) and (-)
terminals identified in the technical specifications are to be used.
Terminal connections
11 Commissioning
In random order:
- Damp safety sensors.
- Apply operating voltage.
- Then actuate the start button if necessary.
The LEDs of the inputs and outputs used and the "Ready" LED light up.
The safety control unit is ready. The safety control unit switches through the
safety output.

Danger
Danger of electrocution!
Ensure that the safety control unit is installed and put into
operation only by specially trained, authorized personnel.
NOTE
Make sure that no external voltage is applied to the safety
inputs when the operating voltage is applied (e.g. by devic-
es with OSSD outputs).
12 Maintenance
Each safety circuit must be checked by specially trained, authorised personnel
in accordance with national regulations within the time-limits specified therein.
(Recommendation: in accordance with application as per EN ISO 14119)
13 Troubleshooting
- If the ready LED and the LEDs of the applied inputs light up, the outputs flash
and the error LED is off, then the safety control unit is waiting for the start
signal at input "ext. contactor /start" (
see also item 13 "Troubleshooting"
).
NOTE
Upon initial commissioning of a safety control unit with a
new configuration, complete validation according to the rel-
evant standards must be carried out.
