These units are the most advanced, rugged and compact engine control modules
we have ever built. They are simple to use but this manual will assist both
engineer and mechanic alike in the installation and operation of these controls.
The
following pages have in order: wiring and operation, expansion, adjustment,
specifications,
physical drawing, drilling guide and warranty information.

In the Standby mode the Engine Control Switch is in the Auto position as the module monitors the Remote
Start Contacts. All that is required for cranking to begin is the closure of the Remote Start Contacts shown
connected across terminals 13 and 14.

Closure of the Remote Start Contacts while in AUTO initiates the Crank mode.The Fuel Relay and Starter Relay
are energized causing
the engine to begin cranking. The Crank mode will continue for the duration of the
settings
of the Crank Cycle Adjust and the Dip Switch, unless Overcrank occurs first. During the Engine Crank
Cycle
the Low Oil Pressure Switch is ignored. To set Cycle Time and Crank Attempts see adjustments page.

The REST cycle is a pause in the cranking sequence and only applies if Dip Switch 4 on the module is in the
Off position. In this mode Fuel is still applied to the engine but the Starter Relay signal is turned off. The cycle
continues for the duration of the Cycle time Adjustment Setting. The Low Oil Pressure fault signal input is
ignored. To set Cycle Time and Crank Attempts see adjustments page.

If the internal speed switch detects a speed equal or above the Crank Disconnect Adjustment Setting the
starter relay signal
turns off, the Low Oil Pressure delay timer is initiated and the appropriate signals indicate as
shown. The LED versions indicate via an LED also. This is a latched condition and must be reset by placing the
Engine Control
Switch in the Off position. The internal speed switch uses the Magnetic Pickup for speed
detection.

If the engine does not start in the allotted time, as determined by the Crank Cycle Adjust and the Dip Switch
settings, the Overcrank Fault occurs. The Fuel and Start relays are turned off and the appropriate signals
indicate as shown. The LED versions indicate via an LED also. The Overcrank condition is a latched condition
and
must be reset via the Engine Control Switch. See Adjustments page for proper settings of adjustments.

The Overspeed fault is armed at engine cranking. If the internal speed switch detects a speed equal or above
the Overspeed
Adjustment Setting the engine is shutdown immediately. The internal speed switch uses the
Magnetic Pickup for speed detection. The Fuel Relay is turned off, the Low Oil Pressure switch is locked out
and the appropriate signals indicate as shown. The LED versions indicate via an LED also. The Engine Switch
must be placed in OFF for reset. See Adjustments page for speed adjustments.

Upon crank termination the Low Oil Pressure time delay begins. After this delay period if the Low Oil Pressure
switch closes the engine will shutdown immediately. The Fuel Relay is turned off and the appropriate signals

To stop engine place switch in the OFF position and engine will shut down immediately. The Fuel Relay is
turned off and the unit draws no power. If the unit is an LED version lamp test may be applied as shown and
all LEDS will light. Since the output system is totally independent of the signal system Lamp Test can be
actuated at any time with no possibility of backfeed.

The FEX3 is shown expanding the control to 6 total engine faults. The FEX3 provides both the fault combining
signal
circuits and the latch circuits. Placing voltage on terminal 7 will place unit in shutdown but it will not
latch. See FEX3 literature for more information.
