WARNING!
Danger of electric shock
– For safety reasons, the low voltage pumps must be
operated using only protective low voltage (SELV in
accordance with EN 60335-1).
CAUTION!
Supply voltages that are too high destroy the pump.
– Do not connect the low voltage pump to voltages of
> 30 V.
– The pump will generate a fault ("switch-off threshold
for supply") in the event that the supply voltage to
the pump is insufficient to ensure reliable function.
The pump will recommence operation as soon as
the supply voltage is restored.
The fault indicator flashes additionally if the supply
–
voltage is interrupted during a stroke, ("threshold for
stroke abort"). Aborted strokes are not counted by
the stroke counter. In doing so, the pump's elec‐
tronic controller periodically checks the supply
voltage ("wait time after stroke abort": 10 min). The
pump will recommence operation if the supply
voltage is sufficient.
The pump's electrical system will shut down com‐
–
pletely in the event that the supply voltage under‐
shoots another threshold. The pump will come out of
standby mode and recommence operation as soon
as sufficient supply voltage is restored.
The programmed thresholds apply to standard lead-
–
acid batteries. ProMinent can adapt them to cus‐
tomer requirements.
Use short large-diameter power leads to minimise
–
faults. Use batteries with low internal resistance.
– If the pump is connected with incorrect polarity, it will
not run because the polarity protection does not
allow any current to flow.
The "external control" socket is a five-pin panel socket. It is compatible
with two- and four-pole cables.
The "Auxiliary rate" function can only be used with a five conductor cable.
