FAULT
Machine does not start, Electric 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 machine does not Electric 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
- Plug not inserted correctly in socket
- Remote control connected?
- Spray jet nozzle dirty or clogged
- Supply voltage too high (over 250 volt)
The machine starts but Material
stops immediately - Material binding properties low
ERR00 (mortar pump seized?)
ERR04 - Material too dry
Material flow to the gun Clogging
stops. -Material hose clogged
A red light illuminates on - Spray jet clogged
the electrical panel - Low level of binder in mix
ERR00 - Sand not suitable for mix
ERR04
The machine stops during The following texts appear on display
operation
- ERR00 : Material pressure or friction on screw too high
- ERR01 :Inverter temperature too high
- ERR02 : Motor temperature too high
- ERR03 :Inverter module current too high
- ERR04 :System overload
- ERR05 :supply voltage too low

CORRECTIVE ACTION
- Check points listed alongside
- Check points listed alongside
- Start unit up from remote control
- Clean nozzle with special cleaner
--Empty 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:
- Bring the density of the material equal to that of a
plastering mortar by adding water
- Work with lower flow rates
- Remove obstruction
- Connection to compressor detached
- Bodies 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
- Sand not perfectly suitable for pumping; correct
- Pipeline length excessive; reduce
- Wait for the motor to cool sufficiently before
restarting
- Check the power line.
- Wait for the motor to cool sufficiently before
restarting
- Probable external short circuit
- as per ERR00
- Pump seized -
- Check 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
