If the pump is completely stopped and an intervention on this one is necessary, cut the supply ; await2 minutes the discharge of the capacitors ;
correct the failure, switch on the supply again. If the defect is major, the action of an after-sales technician is required.

a) The variator supply is
in over-voltage.
b) Load of the pump is excessive.
c) The motor is in short-circuit.
d) La pompe est en surcharge.
e) The sensor cable (4-20mA) is cut
(MODE 2 only).
- Check voltage at the variator terminals.
- Check voltage at the variator terminals.
- Dismantle the motor-variator of the pump,
check it or replace it.
- Density and/or viscosity of the conveyed fluid
are too big.
- Check the correct supply and the cable
connection of the sensor.

If the liquid is toxic, corrosive or dangerous for human being,
SALMSON or the qualified person in charge of the repairing
must be informed. In this case, clean the pump to ensure a
complete safety to the repairing man.
Other defects, not detected by the speed converter, due to the pump.
INCIDENTS
8.1 THE PUMP
IS RUNNING
BUT NO DELIVERY
8.2 THE PUMP
IS VIBRATING
8.3 NO SUFFICIENT
PRESSURE
FOR THE PUMP
8.4 THE FLOW
IS IRREGULAR
CAUSES
a) The pump does not run quickly
enough. :
b) The internal parts are obstructed
by particles :
c) Suction pipes are obstructed :
d) Air in suction pipes :
e) Pump is no more primed :
f) Suction pressure is too low, it
causes generally cavitation noise :
a) Loose on its foundation :
b) Particles obstructing the pump :
c) Difficult rotation of the pump :
a) The motor speed is not
high enough :
b) The motor is defective :
c) Bad filling of the pump :
d) The draining plug is not fully
tightened :
a) The suction head (Ha) is
not respected :
b) The suction pipe has a
lower diameter than the one
of the pump :
c) The strainer and the suction
pipe are partially obstructed :
REMEDIES
a) Check the adequate adjustment of the requirement (conformity to the required
points).
b) Dismantle the pump, replace the defective components or clean.
c) Clean all the pipes.
d) Check tightness of the whole pipe up to the pump and seal it.
e) Fill the pump to prime again. Check foot valve is tight.
f) Too high losses of load on suction or suction head is too high (check the
NPSH of the pump installed and of the installation).
a) Check and tighten completely the nuts of the stud bolts.
b) Have the pump dismantled and clean it.
c) Check the pump turns freely without abnormal sticking.
a) Check the reference is correctly adjusted (conformity of the reference points).
b) Replace it motor/converter.
c) Open the venting device and vent until there are no more air bubbles at all.
d) Check it and screw it again.
a) Study again the installation conditions and the recommendations
described in this instruction.
b) The suction pipe must have at least the same diameter as the suction
pump port.
c) Remove and clean.
