Engine Coolant Temperature Indicator
The engine coolant temperature indicator (25) is located at
the top left side of the front console. It illuminates amber to
indicate high engine coolant temperature.
Tachometer
The tachometer (2) is located on the right side of the front
console. The tachometer is calibrated in RPM x 100 with a
range of zero (0) to 35. It is controlled by the crane's
electronic operating system based on a J1939 message
received from the engine ECM.
Engine Brake On/Off Switch
The engine brake on/off switch is located on the left center
side of the front console. The two position (ON/OFF) switch
(22) energizes the engine brake. When the top of the switch
is pushed, the switch is in the ON position.
Engine Brake High/Low Switch
The two position engine brake high/low switch (20) controls
the amount of engine braking.
When the top of the switch is pushed, the switch is in the
HIGH position.
Ignition Switch
The ignition switch (14) is located on the right side of the
front console. The switch is key operated with four positions:
ACCESSORY (left position), OFF (vertical position), RUN
(position between vertical and right), and START (right
position).
With the ignition switches in both cabs in the OFF position,
all electrical functions are disabled except for dome lights,
work lights, headlights, tail/parking lights, brake lights, turn/
hazard lights, gauge lights, 12V accessory outlets, and
CraneStar, if equipped.
The ACCESSORY position allows functionality to all
electrical components except for the engine ECM and cab
buzzers.
The RUN position is the same for the ACCESSORY position
except the engine ECM and cab buzzers are now functional.
The START position will energize the starter relay which in
turn energizes the starter motor solenoid and cranking will
begin (provided all necessary conditions are met to allow
starting).
Throttle Pedal
The throttle pedal (38) is the right most pedal on the cab floor
and is angled for increased operator comfort. It is used to
control engine speed. The throttle pedal sends a PWM
(pulse width modulated) signal, based on the pressure
applied, to the crane's electronic operating system which in
turn sends a J1939 percent accelerator position message to
the engine ECM.
NOTE:
If crane is equipped with a hydraulic pump engage
clutch and the hydraulic pump engage switch is in
the “engaged” position throttle will be limited to idle.
Regen Initiate/Inhibit Switch
The switch (60) is a three position switch located on the left
side of the carrier cab front console and is used to initiate or
inhibit an active exhaust regeneration. The top portion of the
switch is momentary. Pushing and releasing the top, will
send a signal to the crane's electronic operating system
which in turn sends a J1939 message to the engine ECM
requesting to initiate the active regeneration. The bottom
portion of the switch is maintained. Pushing the bottom, will
send a signal to the crane's electronic operating system
which in turn sends a J1939 message to the engine ECM
requesting both active and passive regeneration be
inhibited. When the switch is in the center position, the
engine will perform passive regeneration as required.
To begin regeneration, the clutch, brake and throttle pedals
must be released. If the crane is currently in the regeneration
state, depressing the clutch, brake, or throttle pedal(s) will
stop regeneration.
If all the conditions have been met to successfully initiate
regeneration, the engine will automatically change speed as
needed. The regeneration cycle may take approximately 20
minutes.
Engine Diagnostic/Idle Switch
The Engine Diagnostic/Idle Control Switch (36) is a two
position maintained rocker switch used to access the engine
fault codes or enable the control of the engine low idle
function.
Diagnostic function - With the Ignition Switch in the RUN
position and the engine off, press the top of the Engine
Diagnostic/Idle Control Switch to view the active engine fault
codes flashing out on the Engine Stop lamp (23) and the
Engine Warning Lamp (24). If there is more than one active
engine fault code, use the Increment/Decrement Switch (35)
to toggle forward and backward through the fault codes. If
there are no active engine fault codes the engine stop and
warning lamps will be on solid simultaneously.
Engine low idle function - With the engine running and the
bottom of the Engine Diagnostic/Idle Control Switch pressed,
the engine low idle may be adjusted using the Increment/
Decrement Switch (35).
Engine Increment/Decrement Switch
The Increment/Decrement Switch (35) is a three position
rocker switch with two momentary positions and a center off
maintained position. Use this switch in conjunction with the
Engine Diagnostic/Idle switch (36) to toggle forward and
