6.4. Over-ride Key-Switch (If fitted)
Should crane overload be reached (or other limitations exceeded, such as maximum radius, minimum
angle, winch line-pull etc), the system will activate the motion cut relay, if installed. This will then stop
further over-loading of the crane. To bypass or temporarily override motion cut, the operator can use
the over-ride key which should be held by the site-supervisor. When the key is inserted and turned on,
the O/RIDE indicator is illuminated as a reminder.
The Mast er Over-ride key-sw itch is located on
the Control Box Unit.
Turn on to deactivate motion lock-outs.
6.5. Disable Key Switch (If Fitted)
The purpose of the disable switch input is to bypass the RCI-1550 should a hardware fault develop.
The override input simply signals to the software that if an overload is present to ignore it, hence is
software controlled. The disable input is a hardware bypass, and in fact no software need to be
running at all. Hence should the main processor fail, the disable input can be used to allow operation
of the crane until the unit can be serviced.
Like the override key, this key should be held by the site supervisor.
6.6. Turning on the RCI-1550
Generally by the ignition key-switch OR as installed.
Power to the RCI-1550 can be derived from the automotive alternator DC supply, nominally 12V or
24V DC namely;
 The crane electrical ignition circuit.
 The crane electrical accessory circuit.
For either DC suppl y, absolut e voltage range is
10 - 40V DC.
As soon as power is applied to the RCI-1550, its display and other indicators should light up and the
RCI-1550 should go through its self-test operation.
6.6.1.
On Power Up
Upon power being supplied, a test pattern is written to the LCD that completely blackens it and all
LEDs will be active. After approx. 5 seconds the test pattern will be replaced by Robway
information for approx. 3 seconds on the graphical LCD. The message “Please Wait” will then be
displayed until communication has been established with the control unit.
The LCD will then display the build information. The operator is required to press the OK button for
the display to proceed to the normal operating mode.
The active “Crane Configuration” is then displayed, the operator is required to press the OK
button if the crane configuration is correct or the Cancel button if incorrect.
Pressing cancel will allow the operator to change the duty and/or falls ( a ‘PIN’ number may be
required to be entered by the operator in order to effect changes). After the crane configuration has
been be confirmed the display will proceed to the normal operating mode.
