Indicating and adjustment elements
Potentiometer
The switch point or the adaption to the
product conductivity can be adjusted via
potentiometer separately for each channel.
Use a small screwdriver to carry out the
adjustments on the potentiometer.
Control lamps
LED in the front plate indicate
operation, switching condition of the relay
outputs and fault signals.
Two yellow LED (6 and 9) for status
indication of the relay or transistor outputs
1 and 2 (LED lights = relay energizes,
transistor conductive, LED extinguished =
relay deenergizes, transistor blocked)
Two red LED (7 and 10) for failure
indication of channel 1 and 2 (LED lights =
channel interferred).
One green LED (11) for indication
operating voltage "on".
