Stainless steel process connection (integral cable)

Symptom
Green LED off
Green LED off, with proper sup-
ply
Green LED on and Yellow LED on
while not responding to product
and/or adjustment.
Hysteresis region too great.
Unequal current in red and black
wire.
Yellow LED won't come on or
off.
Too much current in loop
Red LED lights opposite to the
Yellow LED when this is not
meant to happen.
Red and Yellow LEDs are blink-
ing fast.
Red and Yellow LEDs are blink-
ing while switching.
Solid state contact does not
follow status Red LED.
Yellow LED is lit while probe is
not covered.

33 V DC at all times (10 to 30 V
DC for IS versions).
Defective component in device.
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).
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).
Loop circuitry is DC biased w.r.t.
ground.
Black wire exceeds + 36 V DC
against Ground.
Defective component in device.
Supply voltage too high
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).
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).
Defective component in device.
Probable cause: wrong wiring in
this circuit.
May indicate significant product
