3.1.3 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).
3.1.4 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).
This fuse will not remove the + battery input
power from the PCB when it opens. This means
the exercise timer will not be reset.
3.1.5 SET EXERCISE TIME SWITCH
This switch allows programming the generator to
start and exercise automatically. "See Weekly

3.1.6 SYSTEM READY LED
The System Ready LED (green) has two main pro-
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.
This secondary function is only available with dip
switch two in the OFF position (ATS - automatic
transfer switch application).
