The product OM 1 is shipped with a permanently connected photoelectric
probe.
OM 5 and OM 5+1:
Use a cable with 3 x 1 mm² to extend the probe cable. Use shielded
cables for lengths of more than 15 m. The maximum length of the probe
cables is 50 m. Use underground cables such as NYY 3 x 1.5 mm² for
underground cable installation.
Verify that the probe cable is not routed immediately next to or together
with cables carrying mains voltage.
Connecting the photoelectric probes
1. Route the probe cable through the cable gland at the right.
2. Route the probe cable of the photoelectric probes to the appropriate
terminal block "Sonde 1" to "Sonde 5".
3. Connect the wires of the probe cable as follows:
- Brown to terminal GND
- Green to terminal OUT
- White to terminal IN
4. If a photoelectric probe is not connected:
Jumper the terminals "IN" and "GND" of this terminal block.
Connecting the floating probe (OM 5+1)
1. Route the probe cable through the cable gland at the right.
2. Route the probe cable of the floating probe to the terminals designated
"Min/Max". Connect the two wires to the terminals "IN" and "GND". Any
polarity is permissible.
3. If the floating probe is not connected:
- If the coding plug J1 is plugged in, leave the terminals "IN" and "GND"
