***!! FLASHING !!***
ASSIGN LED
If the Assign Button LED is flashing it means
that one of the relay drivers has gone into pro-
tect mode. There may be a short on the driver
or it might have been a spike that caused it to
trigger.
Press the "ASSIGN" button and it should
clear. If it does not clear observe which relay
does not operate and may be causing a prob-
lem. If it does not clear by unplugging the
relay transfer the load to a spare.
In some cases when the board has been dam-
aged it is not possible to clear the problem
and the board must be replaced.
FLASHING
Relay or Zone LEDs
If the Relay or Zone LEDs Blink this
is not a problem.
A slow blink means that the relay is in
“Timer” Mode. The relay will perform
an automatic shut off usually within
the next 2 hours.
If the Blinking is rapid it means that
the shut off is about to happen and
that if an override button is not pushed
soon the relay or zone will in fact turn
OFF.
To prevent the relay or zone from turn-
ing off one may press the associated
override switch. (Pressing the relay
button or zone button will not extend
the time, it will just turn off the relay.
One can then turn it back on again to
restart the timer.
Flashing ON LINE LED
This LED is supposed to Flash slowly when the
clock is on the bus. In this case the LED will be
mostly OFF with a Flash ON at about 1 time per
second.
If it is flashing rapidly at about 10 times per sec-
ond this means that everything is fine but it is
storing data to non volatile memory so do not
de-power the board.
If it is flashing slowly but is Mostly ON with a
flash OFF this means that the board cannot see
the clock (because it is disconnected) and that
this board is “Mastering the Bus” (acting as the
traffic cop for messages.) If the clock is connect-
ed then there is a problem. Either the clock is
bad or the board has a bad comm chip.
