Fig. 13: Fault message adjustment - Soldering bridges
1 Soldering bridge for fault message adjustment of channel 1 (BR1)
2 Soldering bridge for fault message adjustment of channel 2 (BR2)
Note:
The line monitoring and the fault signal are inactive with this bridge.
If a measuring system is used as part of an overfill protection system,
the bridge on the signal conditioning instrument must not be closed.
With Ex probes, the resistor in the probe housing is already present.
6 .3 Switching point adjustment
The setup refers to channel 1. The procedure is the same for channel
2.
Prerequirements
l Set the selection switch (channel 1) to mode A
l Connect the signal conditioning instrument to power supply
l Turn the potentiometer (channel 1) to position 0
l Fill the vessel until the max. electrode is covered approx. 1 cm by
the product
l Turn the potentiometer slowly clockwise until the yellow LED
extinguishes
The max. electrode is now adapted to the conductivity of the medium,
i.e. the relay (channel 1) deenergises at max. level and the transistor
blocks (channel 1).
Prerequirements
l Set the selection switch to mode B
l Connect the signal conditioning instrument to power supply
l Turn the potentiometer to position 10
