I/O Configuration
Most connections have been given in advance and cannot be changed. See the connection diagram.
For digital outputs
, define whether the function will be active for an activated or deactivated relay.
For digital inputs
, define whether the function/alarm will be active for an interrupted or shut-off switch.
For analogue outputs
, define whether the output signal should be 0-5 V or 0-10 V
For analogue inputs, define:
Temperature sensors:
Normally, the sensor type is a Pt1000 model.Calibration value (+/- 10°C)
Pressure sensors::
Signal type: 4-20mA, 1-5V or 10-90% ratiometric of 5 V supply voltage.
Minimum and maximum pressure range
Calibration value (+/- 5.0 bar)
Please note:
If a function has been connected to an input or output and is subsequently deselected in the configuration, the function
in question will be marked with an exclamation mark (!). In this case, you must either activate the function in the configu-
ration, or deselect the function on the input or output in question.
