INSTALLATION GUIDE - CONTINUATION 11 of 12
Ice Forms On Bubble
Follow steps until the problem is corrected. See
page 5 to order parts.
1. Are blower/heater fans in the housing working?
If not, see “Fans Do Not Turn” opposite.
2. Is the camera dome receiving power? Look for
evidence such as a picture on the video monitor
or dome movement.
3. Detach the dome to access the environmental
PC board.
Note: Power to the heater comes from the
dome. The heater will not function with the
dome removed.
CAUTION: Touch the metal housing
before handling the PC board.
4. Verify power is reaching the housing. Press and
hold switch SW2 and observe the green (ac
power) LED; it should glow steadily. If not,
check power at the J-box and if the ac cable is
plugged into connector P7 on other side of
environmental PC board.
5. Check the heater connector on other side of the
environmental PC board. Is it plugged into
connector P2?
- YES: Unplug the heater cable and check
heater resistance across pins of plug. Is the
resistance approximately 16 ohms?
If yes, replace environmental PC board
0312-2124-03. If not, replace fan/heater
assembly 0400-0935-01 by removing the two
screws.
- NO: Plug the connector in, reinstall the
environmental PC board, and reattach the
dome. If the fans still do not work, replace
the fan/heater assembly.
