Input voltage
Sensor supply +14 V, max. 35 mA short circuit proof.
If the current limit activates, the sensor supply must be disconnected to reset the
protection.
Integrated pull-up 820 Ohm to +14V (configurable for 2 wire sensors with Jumper J1)
Trigger level Adaptive trigger level.
Configurable with Jumper J2:
• 250mV … 6.5V (>500mVpp) [Factory configuration]
• 28mV … 6.5V (>20mV
rms
)
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
