REMOTE ASSISTANCE
The group normally operates on automatic running and is remote-controlled.
USER SAFETY PROCEDURE
ELECTRICAL MAINTENANCE
All interventions must be carried out by skilled personnel.
By means of the control unit, all control, check and reset functions are possible from the external .
Proceed as follows to enter the equipment inner to the control panel:
1. Set the programming switch on LOCKED mode.
2. Check the total stop of the unit .
3. Disconnect the mains line that powers the control panel and switch the main ON/OFF switch of the mains on.
4. Check if the mains has been effectively disconnected. It can be seen by the mains OK LED switched off and by the
display switched to the mains that must indicate zero.
5. Open the control panel and check for possible anomalies to:
• fuses;
• automatic switches;
• thermal relays.
Once maintenance has been completed repeat the procedure in reverse order to reset the unit.
MECHANICAL MAINTENANCE
If the generator should fail to start due to a fuel circuit anomaly, and in an emergency status, here are some suggestions.
How to restore the fuel circuit:
1. Set the programming switch on Manual Start mode without starting the generator. In this way the 15/54, that
powers the fuel interception solenoid valve, is activated.
2. Once filled up with fuel, enable the hand pump situated on the motor until the circuit restoration. The restoration is
reached when the pump becomes harder and harder to move.
3. Start in manual mode ( We suggest to restrict the starting attempts to 10 seconds each with a pause of 15 seconds
in-between to allow the battery to recover efficiently). Once the unit has started and is regularly running, reset the
automatic functions.
PERIODIC CHECKS
To keep the unit in working order, some periodic checks must be made together with those scheduled by the motor
manufacturer and by the installation engineer:
1. check the electrolytic level of the battery every 15 days after the installation and request the assistance of an engineer
if an excessive consumption is noticed. After the initial period, check every 30 - 60 days;
2. generators equipped with pre-heating system motor, check if the motor is hot each time a check is made otherwise
request technical assistance. (WARNING: a cold motor at low temperatures could have difficulty in starting or outputting
once started);
3. If the generator is rarely triggered due to the lack of mains power supply execute an automatic test for at least 2
minutes.
4. if new electrical machines are installed in the system powered by the generator, request technical assistance to check
the suitability of the CG/CG mains/generator switching to the new load.
SUMMARY: On a periodic basis, check the electrolytic level of the clear batteries. Touch the motor to realize if it is
hot (if equipped with pre-heating system) and execute an automatic test.
