Relay Status LEDs
ControlKeeper® TouchScreen Logic Board
are communications going back and forth between the
ControlKeeper
T, the RSC and the relays. If the LED is ON or
OFF all the time, check that the Power LED is lit, then use
the reset button on the ControlKeeper
T and see if the LED
resumes the blinking state. If the RSC Status LED does not
resume its normal flashing state after the ControlKeeper
T is reset, contact technical support. If the LED flashes
continuously without stopping, this indicates that the relay
card is not able to establish communications with the
RSC. Please contact technical support for assistance in
troubleshooting this issue.
Power LED:
The Power LED indicates that the RSC is
getting the proper expected voltage from the transformer.
If this LED is not lit, there is a problem with power to the
RSC board. Check that the power connection is made from
the transformer. Please contact technical support for further
details on troubleshooting.
Relay Status LEDs
There are two LED indicators of importance on the relay
cards. The first is a status LED on each relay. The other is
a relay card status LED. Refer to Figure 16 on page 11 for
location of these LEDs.
Status LED:
The Status LED will flash ON and OFF
continuously under normal operation. The normal pattern
of flashing is ON for approximately 4 seconds then OFF
for approximately 1 second then back ON again. In addition
to this blink pattern, the LED will blink erratically when
there are communications going back and forth between
the ControlKeeper
T, the RSC, and the relays. If the LED is
ON or OFF all the time, check that the Power LED on the
RSC is lit, then use the reset button on the ControlKeeper
T and see if the LED resumes the blinking state. If the
Relay Status LED does not resume its normal flashing
state after the ControlKeeper
T is reset, contact technical
support. If the LED flashes continuously without stopping,
this indicates that the relay card is not able to establish
communications with the RSC. Please contact technical
support for assistance in troubleshooting this issue.
Relay Indicator LED:
The Relay Indicator LED indicates
that the relay is energized or de-energized. If the relay has
been energized, the LED will be ON. If the relay has been
de-energized, the LED will be OFF.
