TROUBLESHOOTING
Use this procedure if:
•
The dome functions but does not pan
•
The dome functions but does not tilt
•
The 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).
To perform this procedure, you must open the
housing and eyeball assembly. The electrical con-
nection between the dome assembly and the
mounting base is made via a special 32-pin spring
finger connector. All other dome connections are
via cable connectors and snap-fit parts.
Fragile parts!
Once disassembled, parts of
the dome housing and eyeball assembly are
“extremely fragile” and may break. Proceed
using extreme care!
Dust cover.
Place this part over the spring
fingers on the I/O board when shipping the
base back to the manufacturer.
Connectors on the I/O board are very
delicate!
DO NOT overtighten these
connectors. Use the a 0.4 x 2.5mm slotted
screwdriver. Larger screwdrivers can
damage the connector.
CAUTION—ELECTROSTATIC SENSITIVE
DEVICE!
Use a grounding strap when
handling PC boards.
Dome Functions but Does Not Pan
If the dome functions but does not pan, you need
to access the CPU board (see page 4-6) and/or
pan motor (see page 4-7).
On the CPU board, is the pan motor ribbon cable
attached to connector P4 and is the metal side of
its fingers towards the contacts of the connector?
•
YES: Replace the CPU board. And if this
doesn’t work, replace the pan motor.
•
NO: Connect cable(s).
Dome Functions but Does Not Tilt
If the dome functions but does not tilt,
you need to
access the camera/lens board (see page 4-9)
and/or tilt motor (see page 4-10).
On the camera/lens board, is the tilt motor’s cable
attached to connector J3? Is the slip ring’s cable
attached to connector J2?
•
YES: Replace the camera/lens board. And if
this doesn’t work, replace the tilt motor.
•
NO: Connect cable(s).
Dome Does Not “Home” or Respond
to Commands (Dead Dome)
If the dome does not respond, you need to access
the CPU board and/or power supply board. For
steps on how to do this, see page 4-6.
On the CPU board, is the power supply cable
attached to connector P3? Is the slip ring cable
attached to connector P2?
•
YES: Replace the CPU board. And if this
doesn’t work, replace the power supply board.
•
NO: Connect cable(s).
