‹3.2.3 15 AMP FUSE

This fuse protects the control console’s DC control circuit against electrical overload and is located inside the control panel. If the fuse has melted open because of an overload, engine cranking and startup cannot occur. If the fuse needs to be replaced, use only an identical 15-amp replacement fuse (type ATO).

‹3.2.4 5 AMP FUSE

This fuse protects the battery charger against electri- cal overload and is located inside the control panel. If the fuse needs to be replaced, use only an identical 5-amp replacement fuse (type ATO).

NOTE:

This fuse will not remove the + battery input power from the PCB when it opens. This means the exercise timer will not be reset.

‹3.2.5 SET EXERCISE TIME SWITCH

This switch allows programming the generator to start and exercise automatically. “See Weekly Exercise Cycle” (see Figure 3.3 and Section 3.7).

‹3.2.6 SYSTEM READY LED

The System Ready LED (green) has two main pur- poses. First, the LED will be ON when the AUTO/ OFF/MANUAL switch is in the AUTO position, utility is present, and there are no system alarms. This ON state indicates the system is fully ready for automatic operation.

The system ready LED will be OFF when the switch is in the MANUAL or OFF positions.

The system ready LED is also used to indicate the presence of utility sensing at the PCB when the switch is either in the AUTO or MANUAL modes. The LED will flash at the rate of 1/2 second on, 1/2 second off if the utility sensing level is below the transfer back threshold.
