Troubleshooting

Cable and/or IS (non-plastic)
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 fol-
low status Red LED
Yellow LED is lit while probe is
not covered
