Other information
The probe cable (maximum length 100 metres) does not have to be screened, but avoid mounting it in parallel with the power supply cables. A screened
cable can be used with the screening connected to the common terminal.

Monitoring a level, filling function, deactivation time
Sensitivity : 5 kW to 100 kW) or Up HS (High Sensitivity : 50 kW to 1 MW).
When the liquid level drops below the probe the relay energises immediately and remains on until
the level of liquid reaches the probe again and remains above it for a period exceeding time delay T
set on the front panel.
If the level of liquid drops back below the level set before the time delay elapses, the relay remains
on.
Note
When the power returns after a power break, the output relay energises immediately if the liquid
level is below the threshold.
Monitoring a level, emptying function, deactivation time
Sensitivity : 5 kW to 100 kW) or Dwn HS (High Sensitivity : 50 kW to 1 MW).
When the level of liquid rises above the probe the relay energises immediately and remains on until
the level of liquid drops back below the probe for a period exceeding the value of time delay T set
on the front panel.
If the level of liquid returns above the level set before the time delay elapses the relay remains on.
Note
When the power returns after a power break, the output relay energises immediately if the level of
liquid is above the threshold.

to 100 kW) , Dwn HS (High Sensitivity : 50 kW to 1 MW).
The output relay remains open as long as the level of liquid has not reached the maximum probe.
Once the maximum level is reached the contact closes and the tank can then be emptied (valve
opened, pump started, etc). When the level drops below the minimum level the contact opens and
interrupts the emptying process.
Note : when monitoring two levels the time delay preventing the wave effect is not in operation.

100 kW) or Up HS (High Sensitivity : 50 kW to 1 MW).
The output relay remains on as long as the level of liquid has not reached the maximum probe. As
soon as the maximum level is reached the contact opens and pumping stops. When the level drops
below the minimum level the contact closes again and pumping restarts to bring the level of liquid
back up.
Note : When monitoring the two levels the time delay preventing the wave effect is not in operation.
Note
When the power returns after a power break, the output relay energises immediately if the level of
liquid is below the threshold.
