Datasheet

If the switch is set to a non-conforming position on energisation, the product goes into fault mode, the output relay stays open and the LEDs flash to signal the position error.
If the switch position changes while the unit is operating, all the LEDs flash but the product continues to work normally with the function selected on energisation prior to the change of position.
The LEDs return to their normal state if the switch is reset to its initial position defined before the last energisation.
(Level: 2LS emptying function (Low sensitivity: 250 Ω to 5 k Ω ), St emptying (Standard sensitivity: 5 k Ω to 100 k Ω ), HS emptying (High sensitivity: 50 k Ω to 1 M Ω ).
As long as the liquid level has not reached the probe maximum, the output relay stays open. Once the max. level is reached, the contact closes, thus allowing the tank to empty (valve opens, pump
starts, etc). When the level drops below the min. level, the contact opens to interrupt the emptying process.
: In two-level control mode the time delay for preventing wave effect is not active.
(Level: 2, LS filling function (Low sensitivity: 250 Ω to 5 k Ω ), St filling (Standard sensitivity: 5 k Ω to 100 k Ω ), HS filling (High sensitivity: 50 k Ω to 1 M Ω ).
As long as the liquid level has not reached the probe maximum, the output relay stays closed. Once the max. level is reached, the contact opens and pumping stops. When the level drops below the
min. level, the contact closes again and pumping restarts so as to make the liquid level rise again.
: In two-level control mode the time delay for preventing wave effect is not active.
(Level: 1LS filling function (Low sensitivity: 250 Ω to 5 k Ω ), St filling (Standard sensitivity: 5 k Ω to 100 k Ω ), HS filling (High sensitivity: 50 k Ω to 1 M Ω ).
When the liquid level drops below the probe for a duration longer than the value of time delay Tt set on the front face, the relay closes and stays closed until the liquid level reaches the probe again.
If the liquid level rises back above the level set before the end of the time delay, the relay does not close.
(Level: 1 - off-delay, LS filling function (Low sensitivity: 250 Ω to 5 k Ω ) or St filling (Standard sensitivity: 5 k Ω to 100 k Ω ) or HS filling (High sensitivity: 50 k Ω to 1 M Ω ).
When the liquid level drops below the probe for a duration longer than the value of time delay Tt set on the front face, the relay closes instantly and stays closed until the liquid level reaches the
probe again and stays above it for a duration longer than time delay Tt set on the front face.
If the liquid level drops back below the level set before the end of the time delay, the relay stays closed.
(Level: 1 - on-delay, LS emptying function (Low sensitivity: 250 Ω to 5 kW Ω ), St emptying (Standard sensitivity: 5 k Ω to 100 k Ω ), HS emptying (High sensitivity: 50 k Ω to 1 M Ω ).
When the liquid level rises above the probe for a duration longer than the value of time delay Tt set on the front face, the relay closes and stays closed until the liquid level drops back below the
probe.
If the liquid level drops back below the level set before the end of the time delay, the relay does not close.
