illuminate. Attention to the diesel and its
associated equipment is required immediately.
7.6 Fuel Spill
Indicates that the relief valve has been manually
opened. This will cause a start of the engine once
the pressure drops below the set value.
7.7 High Engine Temperature
Indicates that the coolant temperature in the water
jackets is extremely hot. The over temperature
switch on the engine signals the controller. The
engine continues to run in the AUTO and
MANUAL modes. In the “TEST” mode and during
the weekly test cycle the engine will shutdown.
7.8 Low / High Fuel
(When Fuel Level Switch Wired)
Indicates that the engine fuel supply is low / high.
The engine continues to run.
7.9 Low Oil Pressure
The controller has an inherent delay to bypass the
low oil pressure alarm during engine start up. After
the delay, should the engine receive a ‘Low Oil
Pressure’ signal, the controller will initiate an
alarm. The engine will continue to run in the
‘AUTO’ and ‘MANUAL’ mode. In the ‘TEST’
mode and during the weekly test cycle this alarm
will automatically shutdown the engine. This
situation will result in serious engine damage if
kept running.
7.10 Low / High Reservoir
Indicates that the water reservoir level is low /
high. (Signal supplied by others)
7.11 Low Room Temperature
(When Thermostat Installed)
Should a “Low Room Temperature” alarm occur
the engine will continue to run.
1 Software versions before V2.91 have a Relief
Valve Discharge alarm instead of the Fuel spill
alarm.
2 Software versions prior to V2.91 have an audible
alarm for Low / High Fuel which followed the
input signal from the fuel tank.

Battery Chargers
Battery chargers are independent chargers
producing a maximum of 10 amps each at full rate.
Each battery charger is fully electronic and will
protect itself by shutting down during a continued
short circuit.
The maximum current draw that the chargers will
draw when operating at 100% charging rate is:
12 Volt System
24 Volt System
1.6 amps - 120V
3.2 amps - 120V
0.8 amps - 240V
1.6 amps - 240V
Three Step Charge
The three steps are referred to as Bulk mode,
Overcharge Mode and Float mode.
Bulk
In Bulk mode, a current of 10 Amps is delivered
into the battery until the voltage reaches 2.4 Volts
per cell for Lead Acid Batteries. (14.4 Volts for a
12 Volt battery). At this point, the battery has
recovered approximately 90% of its capacity.
When the charger senses this state, it switches to
the Overcharge mode.
The battery charger LCD display will indicate
“BULK” while in this mode.
The bulk mode charging may take up to 24 hours
depending on the battery capacity and the level to
which it was discharged.
Overcharge
In the Overcharge mode, the voltage on the battery
is held at 14.4 Volts and the current into the battery
declines. This mode is maintained until the current
into the battery declines to 1.5 Amps. At this
moment, the battery is approximately 99% charged
and the charger will change to Float Mode.
The battery charger LCD display will indicate
“OVER” as well as the battery voltage and the
delivered current.
The overcharge mode charging may take up to 12
hours depending on the battery capacity and the
level to which it was discharged.
Float
In Float Mode, the charger maintains the battery
voltage at 2.23 Volts per cell for a lead acid battery
(13.4 Volts for a 12 Volt battery). Once Bulk and
Overcharge modes are completed, the charger will
maintain the battery charge in Float mode by
regulating to 13.3V. If the charger cannot maintain
the battery capacity while in Float mode, the
charger will begin a new charging sequence by
entering Bulk mode.
The battery chargers incorporate a three step
charge to guarantee the fastest charge times while
optimizing battery life.
