15 CARE AND MAINTENANCE
The following care and maintenance activities should be conducted to ensure the reliable
and safe operation of the CAS-CAM/RF
®
equipment. Note that there are no serviceable
parts located inside the equipment enclosures. Refer servicing to an AMT Service Agent.
15.1 Heavy Vehicle (HV) System
15.1.1 Operational Care
• To prevent fire or shock hazard, do not expose the Heavy Vehicle Display Unit to
rain or moisture.
• To avoid electrical shock, do not open the electrical equipment enclosures. There
are no user serviceable parts located inside the equipment items.
• Ensure that the Heavy Vehicle Display Unit rear panel ventilation holes are not
obstructed for efficient natural convection cooling.
• The audible alarm contained within the Heavy Vehicle Display Unit must not be
blocked with foreign objects in order to reduce alarm sound levels as this is the
primary means of notifying drivers of potential collisions. Consult the AMT Service
Agent if you wish to adjust the alarm sound levels to suit the ambient noise levels of
the particular installation.
• The visual alarms contained on the Heavy Vehicle Display Unit Screen should not
be covered over with foreign objects in order to reduce night vision glare as this is
the secondary means of notifying drivers of potential collisions (the primary means
being the audible alarms). The brightness level can be switched to the lowest
setting on the Heavy Vehicle Display Unit Screen by using the DIM function (refer to
section 10.1.8 for details). The intensity of the LED power indicators on both
equipment items and the Light Vehicle alarm LED indicator have been set at low
intensity levels suited for both day and night visibility.
15.1.2 Pre-Operation Inspection
External Checks
• Visually check that all cameras are clean and are orientated correctly. Clean and
adjust if necessary.
• Visually check that all equipment items and wiring harnesses are secure.
15.1.3 Startup Inspection
• Check the clarity of the Display Unit screen and where visibility is affected, clean
with a window cleaning spray and soft cloth. Ensure that the cleaning process
doesn’t scratch the screen cover or result in cleaning fluid entering the rear
ventilation holes.
• Inspect the clarity of vision from each camera on the Heavy Vehicle Display Unit
and where affected by the build up of foreign material, clean the camera unit
window with a window cleaning spray and cloth. Approved access methods must
only be used when cleaning cameras located at heights.
• Scroll thru all active camera channels to check operation
• Check that no error messages are displayed (refer to section 16.2 ‘System Error
Messages’ for details).
• When operating at daytime, check that DIM function has been set for maximum
brightness (refer to section 10.1.8 for details).
