TROUBLESHOOTING GUIDES
The troubleshooting guide includes WDRR indications and symptoms as it is being used in conjunction with the
Limitless™
input
series. Refer to Section 4 for layout of LEDs, terminals, connections, etc.
SYMPTOM
CAUSE
RESOLUTION
Green power LED is not ON
10 Vdc to 28 Vdc is not applied
to "+" & "-" terminals
Check for proper connection and 10 Vdc to 28
Vdc to "+" and "-" terminals per Section 6.3
Power leads connected in
reverse
Check for proper connection of power: "+" and
"-" terminals per Section 6.3
Green, yellow and/or red configuration
LEDs do not blink ON at start-up
WDRR internal electronics
damaged
Replace WDRR
LED(s) burnt out
Check LED operation per Section 6.2 and replace
WDRR if necessary
Tri-color output LEDs are momentarily
OFF then ON with possible NPN/PNP
output change during normal
operation. Resulting in only green
Power LED on and possibly incorrect
yellow and red LED indication/output
for up to 30 seconds.
ESD/EMI exposure beyond
published specifications or
device performing self check
Determine source for ESD/EMI emissions in
application and take action to remove
Yellow tri-color output LED is flashing
Low battery in Limitless™
input
•
Determine which Limitless™ input has a low
battery using the procedure in Section 6.5
•
Replace Limitless™ switch battery per
Limitless™ input Installation guide
Incorrect battery installed in
Limitless™ input
•
Determine which Limitless™ input has a low
battery using the procedure in Section 6.5
•
Replace Limitless™ switch battery per
Limitless™ input Installation guide
Yellow tri-color output LED is
constantly ON
Dead or low battery in
Limitless™ input
•
Determine which Limitless™ input has a low
battery using the procedure in Section 6.5
•
Limitless™ input status will in this case be
reported as lost RF
•
Replace Limitless™ input battery per
Limitless™ input installation guide
Incorrect battery installed in
Limitless™ input
•
Determine which Limitless™ input has a low
battery using the procedure in Section 6.5
•
Limitless™ input status will in this case be
reported as lost RF
•
Replace Limitless™ input battery per
Limitless™ input installation guide
RF range/distance between
WDRR and Limitless™ input is
beyond capability
Reposition Limitless™ input closer to the WDRR
until yellow LED is no longer ON
Exposure to adjacent
materials/objects and/or
materials/objects
Reposition Limitless™ input away from objects
until yellow LED is no longer ON
Damage or missing antenna
from WDRR and/or Limitless™
input
Replace antenna per Section 8.3
Antenna alignment is not
acceptable
Reposition antenna per Section 8.3
Damage to antenna cable
Replace antenna cable per Section 8.3
Loose antenna or cable
connections
Check connections and tighten as necessary per
Section 8.3
