3. If the floating probe is not connected:
- If the coding plug J1 is plugged in, leave the terminals "IN" and "GND"
open.
- If the coding plug J1 is not plugged in, jumper the terminals "IN" and
"GND".
5.5.3 Adjusting the alarm of the floating probe
The alarm of the floating probe is adjusted by means of the coding plug
J1 (see wiring diagram Page 24).
Setting the floating probe to minimum alarm: 
Mount the probe in such a way that the float is not in contact with in the
liquid.
- Remove the coding plug J1. The two contact pins are visible.
Setting the floating probe to maximum alarm: 
Mount the probe in such a way that the float is in the liquid.
- Plug the coding plug J1 onto the contact pins.
5.5.4 Output
The output signal of the control unit is made available via a voltage-free
relay contact (changeover contact). If no alarm is present, the relay is
de-energised; in case of an alarm, the relay is energised. The alarm signal
can be transmitted to a connected additional alarm unit (for example,
ZAG 01).
VOLTAGE PEAKS WHEN INDUCTIVE CONSUMERS ARE SWITCHED OFF
When inductive consumers are switched off, this can cause voltage peaks and
can lead to adverse effects on electrical systems and may destroy the switching
contact.
• Use commercially available standard RC combinations such as
0.1 µF/100 Ohm for inductive consumers.
Failure to follow these instructions can result in equipment damage.
