Routine Troubleshooting

Use this procedure if:

· Dome does not respond to commands

· Dome does not produce video

· Quality of the video is poor

· Dome has no lens control.

CAUTION:

· DO NOT use this procedure if the dome

functions but does not pan or tilt (see step 2 on

page 22).

· If an I/O board is used, use a ground strap

when handling the board. When shipping a

base having an I/O board, place the dust cover

over the spring finger connector to protect it.

· DO NOT over tighten connector screws on the

I/O board; they are delicate. Use a 2.5mm (0.1")

slotted screwdriver. Wider blade widths can

damage connectors.

Procedure

Follow steps until the problem is corrected.

1. Check video on monitor (a, b, or c).

a. No video? Go to step 2.

b. Contrast or color off?

YES Contact your sales representative for

repair instructions.

NO Go to step 2.

c. Video rolls when switching between

monitors?

YES Use the video controller or switcher to

synchronize video vertical sync phases

of all domes to ac line. For specific

instructions, see installation and

service manual for the controller or

switcher.

NO Go to step 2.

2. Check ac power and video connections at J-

box. Are 24Vac and/or video signal absent?

YES Correct problem at J-box.

NO Go to step 3.

3. Detach dome from base and examine address

switches. Are they set correctly?

YES If dome still doesn't respond, contact your

sales representative for repair

instructions. If you must repair the dome,

see "Detailed Troubleshooting", next.

NO Set correct address and reattach housing

and eyeball assembly.

Steps 4-9 are only for bases with I/O boards!

If the mounting base DOES NOT contain an I/O

board, stop here and contact your sales

representative for repair instructions.
