CAUSE AND CORRECTIVE ACTION MONOPHASE
FA U LT
Machine does not start, E lectric current
compressor does not start - No current delivered to connector of site panel (fuses)?
and the blue light is OFF - No power delivered to machine
(defective connector connection? loose cable?)
- Main swiitch not turned on
- The supply voltage is too high
The machine does not E lectric current
start but the compressor (blu lamp on= main switch in correct position?)
starts no signal on display - Operating selector not in start position
- Hopper grid missing
- P lug not inserted correctly in socket
- Remote control connected?
- Spray jet nozzle dirty or clogged
- S upply voltage too high (over 250 volt)
- The red light is on
The machine starts but Material
stops im mediately - Material binding properties low
E R R 00
(mortar pump seized?)
E R R 04
- Material too dry
- The supply of voltage during work is too high
Material flow to the gun C logging
stops. -Material hose clogged
A red light illuminates on - Spray jet clogged
the electrical panel - Low level of binder in mix
E R R 00 - S and not suitable for mix
E R R 04 The machine stops during The follow ing texts appear on display
operation
- E RR00 : Material pressure or friction on screw too high
- E RR01 :Inverter temperature too high
- E RR02 : Motor temperature too high
- E RR04 :S ystem overload
The com pressor starts up
repeatedly although the
air tap put on the spray jet
-P erforated tube
is closed
-C oupling leakage
The machine is turned on, - The air spray outlet is obstructed
the compressor starts, but - A ir hose bended
the screw doesn't turn

- C heck points listed alongside
- To check that the supply voltage does not exceed
250v
- C heck points listed alongside
- Start unit up from remote control
- C lean nozzle with special cleaner
- The vibro- screen is assembled correctly
--E mpty the hopper, ensure that the screw is not
blocked. when the machine is clean, restart with liquid
cement taking care to mix the solution with at least
400/500 kg of binder per cubic metre:
- B ring the density of the material equal to that of a
plastering mortar by adding water
- W ork with lower flow rates
- To reduce the speed and restart
- Remove obstruction
- C onnection to compressor detached
- B odies in mix with too large section
- Use sand with constantly optimal particle size curve.
- Reduce flow rate before restarting
- Low level of binder in mix, add cement or lime
- S and not perfectly suitable for pumping; correct
- P ipeline length excessive; reduce
- C heck that the power voltage is between 210 and
230 Volt with the machine running and that the cables
are correctly sized, and that there is no other
equipment (cranes, hoists, saws, cement mixers etc.)
connected to the same power line
- Wait for the motor to cool sufficiently before
restarting
- C heck the power line.
- Wait for the motor to cool sufficiently before
