transmit pulses to the magnet
Display switched off, no LEDs
switched on
Display switched on, the pump
is not running.
The pump runs irregularly
If there is no additive the pump
does not go into alarm
conditions
The pump does not run in the
functions: 1xN, 1xN(M), 1:N,
ppm, mL/imp. , L/imp. , mL/m
(with meter)
The pump does not run in the
mA function
The pump goes into alarm
conditions when operating with
the flow switch
As soon as the pump is
switched on it beats two or
three times and then blocks
The probe (pH, Rx, Cl) reading
does not correspond to the
value detected with other
measuring instruments
There is an infiltration
The pump runs but does not
draw the liquid
Factory parameter reset
Warranty
2 years (excluding parts subject to normal wear i.e.: valves, fittings, tube fixing clamps, tubes, seals, filter and
injection valve). Improper use of the equipment invalidates the warranty. The warranty is intended to be Ex Works or
authorized distributors.
Check that the pump is powered correctly (socket and plug): if the pump remains inactive, please
contact our Service Centres.
Check that the programming is correct, or press the START/STOP button; if the problem persists,
check that the external stop is not activated or if the pump is in stand-by due to the intervention of
the level probe.
Check that the value of the power supply voltage is within the specified limits.
Check the connection between the level probe and the relative connector
Check the connection between the meter output and the corresponding connector on the pump,
check that the display receives the pulse from the meter (indicated with a dot lighting up on the
3
left side of the display)
Check the connection between the output of the instrument with the mA output and the pump
input. Check that the polarity is correct.
Check the connection between the output of the flow switch and the corresponding
•
connector on the pump;
Make sure that the pump is actually injecting liquid and not air.
•
Check the settings of the Level and Flow Sensor menu (if featured in the pump menu)
Clean the probes. Check the state of ageing of the probe. Try and recalibrate the probe.
Through the head gasket
Undo the four head screws and make sure that the o-ring of the pump body is in good condition
and that the diaphragm is screwed on correctly, otherwise replace them. Also make sure that the
infiltration did not damage the board or the magnet.
Through the control panel
Observe the board and check the state of preservation of the electrical components and printed
circuit tracks. Check the electrical resistance of the electromagnet.
In the event that one of the two components is damaged, replace it. Make sure that all the
components that secure the flow pipe are mounted properly and that they are not damaged.
Replace also serigraphy which enabled the infiltration.
Remove the suction and discharge valves, clean them and replace them in the same position.
Check the state of clogging of the filter and the injection valve
If certain issues cannot be solved, try to reset the pump, to restore all the factory settings (see
RESET chapter)
