If starting fails after these 5 attempts (minimum 4) the batteries are to be replaced.
3.7 SWITCHING SCALING TEST
If the utility system is modified, check the scaling of the mains/generator line switching. The maximum load current must not exceed the
switching limit values indicated on the internal nameplate.
3.8 TROUBLE SHOOTING
All control panels are marked with a work order number written on the test nameplate inside the panel. All the technical and constructional
data of the control panel are associated with the work order number therefore you must refer to this when requesting technical assistance or
spare parts.
The following details must be indicated in any event:
1. type of electronic board (indicate on front panel);
2. battery voltage (12 or 24V);
3. mains voltage (230 or 400V);
4. generator capacity (KVA);
5. frequency (50-60 Hz);
6. indications displayed on GCM02 module when the problem occurs;
7. operational mode (AUT. or MAN);
