CONTROLS AND OPERATING PROCEDURES OPERATOR MANUAL NTC55
3-8 Published 9-26-2018 Control # 646-02
Pre-selection of a button or a combination of buttons (one or
more beams or one or more jacks) may be selected within 5
seconds before pressing the enable switch to activate all
selected functions. A blue LED will illuminate for 5 seconds
indicating the button has been selected. A red LED will
illuminate if a selection is unavailable.
Press the extend or retract button while holding the enable
switch to complete the operation.
NOTE: Extension beam and jack cannot be operated
simultaneously.
Extend Button
The extend button is located on the outrigger control panel
(Figure 3-2) and is used in conjunction with the enable
buttons to control both the outrigger beams or the jacks
functions.
Retract Button
The retract button is located on the outrigger control panel
(Figure 3-2) and is used in conjunction with the enable
buttons to control both the outrigger beams or the jacks
functions.
LED Indicators
LED indicators display the status of the control button being
selected (Figure 3-2) on the cab outrigger control panel. A
LED will illuminate for 5 seconds after a button has been
selected.
• Blue indicates active selection
• Green indicates pre-selection is enabled
• Red indicates inactive selection (For example: trying to
pre-select and enable an outrigger beam and jack to
operate at the same time)
Module Power
The module power indicator is located on cab outrigger
control panel and indicates the outrigger control station
(Figure 3-2) is activated when a green LED illuminates. The
control station cannot be activated if the crane is performing
another function. (For example: operating the boom.)
Outrigger Beam Selector Button
The outrigger beam selector buttons (Figure 3-2 and
Figure 3-3) are used to operate the front or rear outrigger
beams. Both sides can be operated from the cab outrigger
control panel.
NOTE: The following details apply to both ground station
control panels as indicated.
The ground control outrigger beam selector switches
(Figure 3-1 and Figure 3-3) are used to operate the front or
rear outrigger beam only on the side of the crane the ground
control is located.
• The panel on the right side operates the outrigger
beams for right side only.
• The panel on the left side operates the outrigger
beams for left side only.
Outrigger Jack Selector Button
Use the outrigger jack selector buttons (Figure 3-2) to indi-
cate which jack you desire to operate.
Single Front Outrigger Button (SFO) - if equipped
The single front outrigger (SFO) switch (Figure 3-2 and
Figure 3-3) is located on the outrigger control panel (if
equipped) for both cab outrigger controls and ground
outrigger controls. The SFO is used to lower and raise the
optional single front outrigger. To operate the SFO, press the
SFO button to activate and then press extend/retract button.
The SFO automatically retracts if any of the other jacks are
adjusted and must be reset if lifting is to be continued.
Outrigger Selector Valve
After pushing the desired selector buttons, the enable button
and either the extend or retract button energizes the control
solenoid to allow hydraulic fluid to flow through the control
solenoid valve and the individual solenoid valves and moves
the selected component in the desired direction. In addition,
when the buttons are pushed, a signal is sent to the engine
ECM to increase the engine speed above idle for operation
of the outriggers.
Emergency Stop Switch
There is an emergency stop switch (Figure 3-2 and
Figure 3-3) located at each outrigger control on each side of
the carrier and inside the cab on the front console
(Figure 3-1 and Figure 3-2). Pressing an emergency stop
switch shuts down the engine.
NOTE: Only use the emergency stop switch in the case of
an emergency to shut down the engine; do not use
the emergency stop switch regularly as a means of
turning off the crane.
Crane Level Indicators
A bubble level indicator is located inside the cab near the
right side armrest. This indicator provides the operator with a
visual indication for determining how level the crane is when
operating the outriggers. There are two additional level
bubbles located at each ground level control station.
NOTE: To ensure a true reading always make sure the cab
tilt is completely lowered.
Ground Station Outrigger Control Panel
The following paragraphs describe the outrigger controls and
indicators (Figure 3-3) found on the ground station outrigger
control panels.
