Power Circuit
Unswitched power is available from the starting motor
battery terminal to 50 amp thermal circuit breaker battery
terminal. Unswitched power is available from 50 amp
thermal circuit breaker battery terminal to key switch
terminal A and control module terminal J3-6.
When the key switch is turned to the run position, voltage
is provided from key switch terminal B to control module
switch power input terminal J3-2, powering up the control
module. Voltage is also provided from key switch terminal
B to control module select 2 input terminal J4-2,
activating the input. With the select 2 input activated, the
control module selects the software program for this
machine. This allows the control module to be used in
more than one machine.
With the internal switched power relay energized,
switched power is available from switched power relay
terminal 87 to control module terminal J3-5. Switched
power is available from control module terminal J3-5 to
splice 100. From splice 100, switched power is available
to the park brake proximity switch.
With the internal switched power relay energized,
switched power is available from switched power relay
terminal 87 to control module terminal J3-3. Switched
power is available from control module terminal J3-3 to
splice 90. From splice 90, switched power is available to
the cruise control switch.
Cruise Control Circuit
When the cruise control switch is placed in the on
position, voltage is provided to the cruise control module,
powering up the module. With the module powered up,
current flows to the cruise control magnet, energizing the
magnet. With the magnet energized, the traction pedal
linkage is held in the current position.
When the park brake pedal is de-pressed, voltage is
provided from the switch to cruise control module cancel
input terminal J8-1, activating the input. With the input
activated, the cruise control module de-energizes the
cruise control magnet, releasing the traction pedal
linkage. To re-enable the cruise control circuit, the cruise
control switch must be placed in the off and then in the on
position.
