Unequal current in red and
black wire
Yellow LED won't come on
or off
Too much current in loop Supply voltage too high Ensure power range equals 12 to
Red LED lights opposite to
the Yellow LED when this
is not meant to happen
Red and Yellow LEDs are
blinking fast
Red and Yellow LEDs are
blinking while switching
Relay contact does not
follow status Red LED
Yellow LED is lit while
probe is not covered

Loop circuitry is DC
biased w.r.t. ground
Black wire exceeds + 36
V DC against Ground
Defective component in
device
Incorrect polarity on red
and black loop terminals
Proper power not
applied to device
Power range must equal
12 to 33 V DC at all times
(10 to 30 V DC for IS
versions)

May indicate significant
product buildup.
Correct loop circuitry
Remove cause of voltage on the
red wire and/or bias
Contact distributor
33 V DC at all times (10 to 30 V DC

Reverse polarity on loop terminals
Check power source
Minimum 12 V DC on the terminals
when the signal current is 20 mA
(minimum 10 V DC for IS versions)
