The switching behaviour of the relays can be determined with DIP switches 5 and 6:
max max: The relay is activated when the input signal is equal or above the limit
min min: The relay is activated when the input signal is equal or below the limt
For applications with functional safety (SIL2), the device must be configured that
the relay is deactivated in the event of an error!
With use of the analog output for SIL2, the evaluation unit must be configured that
values > 21 mA and values < 1 mA are recognized as errors.
Sensor break and sensor short-circuit
In the measuring ranges with Pt100 sensors, breaks and short-circuits are moni-
tored.
In this case, the relays are deactivated and the scale lighting blinks red.
The analog output drops to approx. 0mA.
