Maximum monitoring (Pump down)
Connection of probe rods E2 and E3 (Bridge E1-E3). Alternatively the
electrically conducting container can be connected in lieu of the test
probe E3.
When the probe E2 gets moistened the set interval of the tripping delay
(DELAY ON) begins. After the expiration of the interval the output relays
switch into on-position (yellow LED illuminated). When the air-fluid level
sinks below the probe E2, the set interval of the turn-off delay (DELAY
OFF) begins. After the expiration of the interval the output relays switch
into off-position (yellow LED not illuminated).

Note
Use cables with low capacity for wiring the probes especially with
extended wiring length.
Following processes are suggested for the adjustment:
- The existent time delay should be to minimum (0,5s).
- The function selector switch must be in position pump down.
- Turn the sensitivity controller slowly clockwise from min to max until
the relais switch into on-position. (probes must be in dipped state)
- The moistened probes should be taken out of the liquid to control
if the relais switch into off-position. If the relais doesn‘t switch into
off-position, turn the sensitivity controller slightly back to min. (coun
ter clockwise)
- Set the existent time delay to desired value to fade out a short term
moisten the probes by waves in the liquid.
- Set the function selector switch to desired position. (either pump up
or pump down)
Functions
Pump up
Connection of the probe rods E1, E2 and E3. Alternatively the electrically
conducting container can be connected in lieu of the test probe E3.
When the air-fluid level falls below the minimum probe E2 the set interval
of the tripping delay (DELAY ON) begins. After the expiration of the
interval the output relays switch into on-position (yellow LED illuminated).
When the air-fluid level again rises above the maximum probe E1, the
set interval of the turn-off delay (DELAY OFF) begins. After the expiration
of the interval the output relays switch into off-position (yellow LED not
illuminated).
