Trouble Shooting
What do Flashing LEDs Mean?
1
The online LED flashes "on" once per second
when the panel can see the clock.
1
If flashing about 10 times per second, the card is
storing data to memory, so do not de-power the
board.
1
If it is flashing slowly, but is mostly on with a
flash off, the card cannot see the clock. If this is
the Master Panel (with the DTC) the control card
needs to be replaced. If it is a slave panel, it is
disconnected from the DTC Clock. Check that the
Cat. 5 is plugged in and that your crimping is OK.
2
If the Assign LED is flashing, one of the relay driv-
ers has gone into Protect mode. There may be
a short on the driver or a power spike may have
caused it to trigger.
2
Press the ASSIGN button and it should clear. If it
does not clear, toggle each relay with the manual
override and observe which relay does not oper-
ate. If it does not clear by unplugging the relay,
transfer the load to a spare.
2
If the control card has been damaged, and it is not
possible to clear the problem, the card may need
to be replaced.
3
A blinking Relay LED means the relay is in Timer
mode and will perform an automatic shut-off within
several hours. Timer mode is initiated when a
clock schedule sweeps off relays in a group which
is programmed as Maintain+Timer or Maintain+Off
Sweep (see page 10 of the Basic Programming
Guide).
3
If it is blinking rap-
idly, shut-off is immi-
nent (usually within 5
minutes) and unless an
override switch is acti-
vated the relay will turn
off.

To initiate an override (re-start the timer) from the
control card, press the relay button once. Or use
an override switch.
Lights Won't Turn Off
1.
Is the panel on and receiving power? Check
that the breaker feeding the panel electronics
is on; check the input voltage with a meter.
2.
Check that the Hand-Auto switch is set to
"Auto."
3.
Check that the jumpers from the control cards
to the relays are properly seated and plugged
in.
4.
Press the Toggle buttons for each relay and
listen for a clicking sound. If the relays sound
like they are responding then check the relay
contacts. Check for continuity when the relay
is "on" and then "off". If the relay continuity is
correct, the problem lies with the wiring (no
neutrals, wrong circuits, etc).
Lights Won't Turn On
1.
Check that the breakers feeding the relays
are powered up. Check the Line side of each
relay with a volt meter for proper voltage.
2.
Press the Toggle buttons for each relay
and listen for a clicking sound. If the relays
sound like they are responding, then check
continuity with a meter (ensure that breaker is
de-powered) when the relay is "on" and "off".
If the relay is responding and the lights are
not turning on or off, the problem lies within
the wiring (no neutrals, wrong circuits, etc).
Can't See the Clock Display
1.
Adjust the contrast level on the top of the
DTC Clock.
