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
min
and I
max
.
I
min.
= 0.5…25 mA
I
max.
= 0.5…25 mA
• Monitoring of non powered sensors
[For 2 wire sensors such as electromagnetic sensors.]
Æ The sensor is considered to be defective if the circuit is disconnected.
