Filling Control – between Min.
and Max. levels.
Under normal operation the liquid
level can be expected to cycle
between the Minimum and the
Maximum electrodes, B2 and B1
(plus a degree of over and
under-shoot).
Switch On:
• On “power-up”, if the liquid is
below B1 the output relay will
operate after time T has expired.
• On the liquid level falling below
B2, the output relay will operate
after time T has expired.
Switch Off:
• On the liquid level reaching
electrode B1, the output relay will
de-energise after time T has
expired.
• On “power-off”, the output relay
will immediately de-energise.
Filling Control – about a single
level, B1.
Under normal operation the liquid
evel can be expected to cycle about
the level set by electrode B1 with a
degree of over and under-shoot.
Switch On:
• On “power-up”, if the liquid is
below B1 the output relay will
operate after time T has expired.
• On the liquid level falling below
B1, the output relay will operate
after time T has expired.
Switch Off:
• On the liquid level reaching
electrode B1, the output relay will
de-energise after time T has expired.
• On “power-off”, the output relay
will immediately de-energise.
