8.5 Connecting the control circuits

The connection for the control circuits is permitted only for switching low voltages. The control
circuits are dependent on the rated current to protect with an appropriate fuse or the rated current
to the control circuits must be limited by other measures to the maximum value.

9. Commissioning and functional test

The plant / machine must be tested for proper function after all of the electrical connections have been
established and the supply voltage has been turned on:
• Actuate the sensors in sequence
• Check the switching units for proper reaction
The safety system must be professionally inspected at appropriate intervals. The inspection must be docu-
mented in such a way as to be comprehensible at all times.
The requirements of the plant/machine manufacturer are to be taken into account and followed.

10. Error diagnosis

Only the green LED may illuminate if the supply voltage has been correctly connected . If one of the red LEDs
illuminate, there is an error in the system which can be pinpointed with the aid of the LED.
LED
LED's are not The supply voltage is missing, too low
illuminated or has been connected incorrectly
Green LED flashes Internal error is indicated by the
cyclically number of pulses
A single red LED Contact edge(s) not connected,
is illuminated connected incorrectly or faulty
One of the contact edge connections
is not being used
* If the error is not in the wiring, the function of the electronics can be tested by connecting an 8.2 kΩ
resistor to the respective SCE input on the switching unit.
If the electronics work perfectly after performing the test, the sensor must be checked using an ohmmeter.
To do this, the connection of the sensor to the switching unit must be disconnected and connected to
an ohmmeter. The resistance must be 8.2 kΩ ±500 Ω when the sensor is inactive and must not exceed
500 Ω when the sensor is active.

The control circuit to be monitored for the opening movement (channel 1, stop-
opening movement) is to be connected to the STOP Opening terminal pair; for the
closing movement (channel 2, stop closing movement), the appropriate control
circuit is to be connected to the STOP Closing terminal pair .
Error

Error correction

Check connections and supply voltage.
According to the error indicator, switch off
the output, switch off the device or check the
supply voltage .
- Check the connections of the corresponding
sensors (squeezed or brittle supply lines, etc.)
- Check sensors *
- Check safety contact edge(s)*
Any contact edge connections that are not
being used must be permanently bridged
using one of the supplied 8.2 kΩ resistors
