Code B Failure Conditions
•
Blinking 2 times/second -
The battery on this board
that backs up the CUB configuration during power
failures has failed. If you see this light flashing, the
battery will need to be replaced to avoid loss of con-
figuration.
Also, check the position of the Enable Battery jump-
er, located at the bottom right of the board just un-
derneath the output plug-in board. If this jumper is
set to the DOWN position, move it to the UP posi-
tion. This will enable the battery and should cause
the Code B light to stop flashing.
5.4. Relay Output LEDs
Each relay output point on a MultiFlex has
an indicator LED that shows the status of the
output. This LED is lit to show the output is ON,
and unlit to show the output is OFF.
The definition of ON and OFF in this case is
determined by the position of the fail-safe dip
switch (see
Table 4-2
). Therefore, if the output’s
switch is UP, a lit LED means the path is
CLOSED for N.C. contacts and OPEN for N.O.
contacts.
