Indicating and adjustment elements
Potentiometer
The switch point or the adaption to the
product conductivity can be adjusted via a
potentiometer.
Use a small screwdriver to carry out
adjustments on the potentiometer.
Control lamps
LED in the front plate indicate
operation, switching condition of the relay
output and fault signal.
One yellow LED (3) for status indication of
the relay or transistor output (LED lights =
relay energized, transistor conductive,
LED extinguished = relay deenergized,
transistor blocks)
One red LED (1) for failure indication (LED
lights = fault signal).
One green LED (4) for indication operating
voltage "on".
