All Relays Not Closing:
Check voltage between Relay Board CN5 pins 1
and 3.
If 120 VAC is not present, the wire between Relay
Board CN5 pin 3 and neutral output of Noise Filter 1
is open.
If 120 VAC is present, continue to next check.
Check voltage between Relay Board CN01 pins 2
and 4.
• If 12 VDC is present, replace the Smart Board.
• If 12 VDC is not present, Smart Board is not
supplying relay operating voltage. (See
troubleshooting section.)
Board
Single Relay Not Closing
Locate the inoperative relay in the Relay Chart in
next column.
Check voltage between the selected relay pin and
Relay Board CN01 pin 4.
• If 5 VDC is present, replace Relay Board.
• If 5 VDC is not present, replace Smart Board.
Note: For situations where the above mentioned 5
VDC is not present, some relays operate loads that
can be controlled by the consumer from the Glass
Touch Assembly. If the in-operative relay is such,
make sure the option is selected at the key panel. If
it is, and the relay is still inoperative, check harness
between Glass Touch Assembly and Smart Board.
If harness is OK, replace Glass Touch Assembly and
Smart Board.
