FAULT
- ERR00 : Hopper grille open or incorrectly located.
- Connection plug not inserted
- System malfunction.
- ERR01 : High circuit board temperature (Inverter).
- ERR02 : High screw pump motor temperature.
- The motor has been subjected to overloading for a long
time.
- ERR03 : Too much power required from screw pump
motor (motor jammed).
- ERR04 : Screw pump motor overload warning.
- ERR05 : The compressor turns on and off too frequently
(<5 start/min)
- High leakage from the piping
The machine stops
during operation
- ERR06 : Compressor blocked at the start
- ERR07 : Current loss to ground or system malfunction.
- ERR 08 : Power voltage too low:
- Lower than 180V for versions 220V
- Lower than 85V for versions 115V
- ERR09 : Overload current on motor vibrating screen
------------ : Voltage input >265V
- BLOC : Motor screw pump jammed
- STOP : Inlet air on compressor is closed
- Jet nozzle closed
- Nozzle clogging
- Pipe clogging from machine
The compressor starts -Perforated tube
up repeatedly althou- -Coupling leakage
gh the air tap put on
the spray jet is closed
The machine is turned -The air spray outlet is obstructed
on, the compressor -Air hose bended
starts but the screw
doesn't turn

CORRECTIVE ACTION
- Ensure the grille is properly located
- Insert connection plug
- Contact Assistance Service
- Wait for it cool down
- Wait for it cool down
- Check the mixture
- Resize the lenght of the piping
- Check the mixture
- Decrease the speed of the screw pump
motor
- Ensure that the power voltage is > 205V
-Replace the gaskets
- Switch off and switch on the compressor
- Contact Assistance Service.
- Check for water in system.
- Check power supply connection
- Check the motor vibrating screen
- Disconnect any electrical device on the
power grid
- Check power supply connection
- Check whether the stator and rotor are
jammed together
- The warning automatically disappears if
the machine starts normally after the halt.
- Clean the air nozzle and unblock the air
hose.
-Replace the gaskets
-Seal the couplings
-Replace the air tap of the spray jet
-Lean nozzle with special cleaner
