The UV Hood Wiring Board is an integral part of the UV interlock
system. All interlock activations are indicated by the LED’s next to
each component wire attachment. The Magnetic Switches used
to determine if the filters are in place are broken down into groups
of four switches, shown below. If any switch fails the group of four
switches will turn off the LED at the point of connection to the UV
Hood Wiring Board. To determine the bad switch or magnet you will
need to use a voltmeter with continuity detection. You will then need
to check the continuity across each switch on that circuit. Ex: To do
so for Extractor #9 check for continuity across F9 & F9. To check
Filter 10, check for continuity between F9 & F10.

Once repaired or replaced the LED should again light up
when all XG Extractors are in place.
