Detailed Troubleshooting
Use this procedure to determine if the problem is a
simple cable connection or a major component.
To perform this procedure, you must open the
housing and eyeball assembly. Refer to
"Disassembling the Dome" on page 27.
CAUTION:
•
DO NOT use this procedure if the dome
functions but does not pan or tilt (see page 22).
•
If routine troubleshooting did not solve the
problem, the manufacturer strongly
recommends you ship the entire dome
(including base, if an I/O board is used) to the
National Service Center (NSC) for service. If
you must perform detailed troubleshooting, use
extreme care when disassembling parts!
•
When shipping a base with I/O board back to
the NSC, place the dust cover over the spring
fingers to protect them.
•
Delicate connector screws on I/O board. DO
NOT over tighten them! Use a 2.5mm (0.1")
slotted screwdriver. Wider blade widths can
damage connectors.
•
Dome contains electrostatic-sensitive PC
boards. Use a ground strap when handling
boards.
Procedure
1. Match symptom to one of the following criteria:
−
Dome functions but does not pan
−
Dome functions but does not tilt
−
Dome does not "home" or respond to
commands even when attached to another
dome's base and its address switches are
set correctly (dead dome).
2. Choose a, b, or c to determine if problem is a
cable connection or major component.
a. Dome functions but does not pan.
On CPU board, is pan motor ribbon cable
attached to connector P4 and is metal side of
its fingers towards contacts of connector?
YES Replace CPU board. If this doesn't
work, replace pan motor.
NO
Connect cable(s).
b. Dome functions but does not tilt.
On camera/lens board, is tilt motor cable
attached to connector J3? Is slip ring cable
attached to connector J2?
YES Replace camera/lens board. If this
doesn't work, replace tilt motor.
NO
Connect cable(s).
c. Dome does not "home" or respond to
commands (dead dome).
On CPU board, is power supply cable
attached to connector P3? Is slip ring cable
attached to connector P2?
YES Replace CPU board. If this doesn't
work, replace power supply board.
NO
Connect cable(s).
