IMER INTERNATIONAL S.p.A.
IMER MORTAR MIXERS
FAULT
CAUSE
CORRECTIVE ACTION
Machine does not start,
compressor does not start
and the blue light is OFF
Electric current
- No current delivered to connector of site panel (fuses)?
- No power delivered to machine
(defective connector connection? loose cable?)
- Main swiitch not turned on
- Check points listed alongside
The machine does not
start but the compressor
starts no signal on display
Electric current
(blu lamp on= main switch in correct position?)
- 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)
- Check points listed alongside
- Start unit up from remote control
- Clean nozzle with special cleaner
The machine starts but
stops immediately
ERR00
ERR04
Material
- Material binding properties low
(mortar pump seized?)
- Material too dry
--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
Material flow to the gun
stops.
A red light illuminates on
the electrical panel
ERR00
ERR04
Clogging
-Material hose clogged
- Spray jet clogged
- Low level of binder in mix
- Sand not suitable for mix
- Remove obstruction
- Connection to compressor detached
- Bodies in mix with too large section
- Use sand with constantly optimal particle size curve.
The machine stops during
operation
The follow ing texts appear on display
- 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
- 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
