When the unit has faults caused by conditions affecting its correct operation, an audible alarm
will sound and a fault number will show on the COUNTER display. The system does not allow
an alarm to be reset until the fault causing the alarm has been corrected. After resetting, the
MODE key must be pressed.
The procedures recommended to determine the possible causes activating the alarms are
indicated in the following:
1. Maneuvering Voltage under 170 V

Check the electrical supply connections.

Check the transformer thermal limit switch.
2. Maneuvering Voltage over 270 V

Check the electrical supply connections.
3. Excessive ISO Pressure (deactivates the directional valve and the heating system)

Check the product pressure.

Check the number 10 led of the printed circuit: it must be lit.

Check the over pressure safety switch.
4. Excessive POL Pressure (deactivates the directional valve and the heating system)

Check the product pressure.

Check the number 11 led of the printed circuit: it must be lit.

Check the over pressure safety switch.
5. Excessive ISO temperature (deactivates the POWER CONTROL)

Check the heater heating system.

Check the connections of the safety thermostat and allow it to cool so that it makes an
automatic reset.

Check the number 12 led of the printed circuit: it must be lit.
6. Excessive POL temperature (deactivates the POWER CONTROL)

Check the heater heating system.

Check the connections of the safety thermostat and allow it to cool so that it makes an
automatic reset.

Check the number 13 led of the printed circuit: it must be lit.
7. Fault key (it only turns on when the machine is connected to the mains)

Check the keyboard.
8. Motor fault (the motor stops)

Check the amperage draw on the hydraulic motor.

Check the electrical connection of the hydraulic motor.

Check the number 15 led of the printed circuit: it must be turned off.
9. Fault in Hose Heating System (deactivates the POWER CONTROL)

