voltage
Integrated pull-up 820 Ohm to +V of the sensor supply (with Jumper J1)
Trigger level adaptive Trigger level.
Configurable with Jumper J2:
• 250mV … 6.5V (>500mVpp) [Factory configuration]
• 28mV … 6.5V (>20mV

Screen A terminal is provided for the sensor cable screen. This terminal is connected to
the sensor supply 0V. (0VS)
Sensor monitoring 1 of 3 settings may be configured via software:
• No Sensor Monitoring
• Monitoring of powered sensors
[
Also for 2 wire sensors supplied via the Pull-up resistor (Jumper J1) ].
Æ The sensor is considered to be defective if the sensor current
consumption falls outside of I

For 2 wire sensors such as electromagnetic sensors.]
Æ The sensor is considered to be defective if the circuit is disconnected.
