3.5 Display Console Overview
The OPERATOR’S DISPLAY CONSOLE allows the user to see the crane values (angle, radius, load,
etc.) and crane configuration selection. The display also provides calibration functions used for testing
and fault diagnosis.
When operated for extended periods, under extreme conditions, the console can become damaged.
The damage is not always apparent. To help identify subtle faults that are sometimes difficult to find,
please review the following comments.
3.5.1 Unresponsive Buttons
Please note that all button options are not available for use at all times. It is important to verify that the
non-responsive button is programmed to respond during the operation of the System. Press the button
in the center. Pressing th
e printed symbol ‘at one end’ may not activate the switch underneath. Buttons
that are damaged or have a surface that is worn may cause the switch underneath to operate
improperly. In this case, refer to SECTION 3.6.5 REPLACING THE DISPLAY CONSOLE.
3.5.2 Connectors
A single circular connector, common to all display models, is positioned on the rear of the display
console. For bracket-mounted applications, it is clearly visible on the rear of the housing. On flush-
mounted versions, it is “hidden” behind the panel, within the dash assembly. This connector carries
power and signals from the computer unit to the display console. Examine this connector carefully, it is
possible for the pins and sockets within the connector halves to bend, break, or “be pushed back”
inside the housing.
On flush-mounted display consoles (vertical model), one additional connection, besides the circular
connector is required: The horn drive wire is a single black lead that should be attached to the black
terminal on the rear of the display console housing.
3.5.3 Horn
On vertical FLUSH-MOUNTED CONSOLES, the HORN is outside the housing. If there is a problem
with the horn, ensure the HORN DRIVE WIRE is connected correctly to the black terminal on the rear
of the display console housing. Release the display console from its connections and pull it gently
forward. If the wire is intact, connected correctly, and the horn is still not operating properly, the horn
may need to be replaced.
3.5.4 Moisture
The DISPLAY CONSOLE offers protection against dust and water, when correctly installed.
