Operating Instructions SWT-2000 DYNALCO
5
Sensor monitoring 3 sensor monitoring settings are available in the configuration software:
• No Sensor Monitoring
• Monitoring of supplied sensors (active Sensor Types)
[Also for 2 wire sensors that are supplied via the internal Pull-up resistor (1k Ω)
Æ Sensors drawing current outside of I
min
or I
max
are considered to be faulty.
I
min
= 0.5…35mA
I
max
= 0.5…35mA
• Monitoring of non powered sensors (passive Sensor Types)
[For 2 wire sensors such as electromagnetic sensors.]
Æ
The sensor is considered to be faulty if the line is broken.
Here the sensor impedance is dynamically measured.
Z < 60 k
Ω = OK
Z > 125 k Ω = NOT OK
