Operating Instructions SWT-2000 DYNALCO

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 (1kΩ)

Æ Sensors drawing current outside of I

min

or I

max

are considered to be faulty.

min

= 0.5…35mA

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 kΩ = OK

Z > 125 kΩ = NOT OK
