Control of two levels, emptying function
(Level : 2, LS 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.
NB
: In two-level control mode the time delay for preventing wave effect is not active.
Control of two levels, filling function
(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.
NB
: In two-level control mode the time delay for preventing wave effect is not active.
One-level control (min. probe), filling function, on-delay
(Level : 1 - on-delay, 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
).
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.
