7.12.7 Display in programming mode of polarity of digital inputs / outputs
The parameters enable the configuration of:
1. Digital inputs
2. Digital outputs (relays)
3. Proportional outputs configured as ON/OFF outputs
4. Analogue inputs configured as digital inputs
to enable assignment of a function and control of polarity.
Example of display in programming mode:
The lower display shows the parameter label (CF37) for configuration of the digital input ID8. The upper display shows label
“c” or “o” and the relative configuration number.

7.12.10 Alarm relay / open - collector / buzzer notes
The unit features a general alarm relay that combines all alarms on a single output contact.
The relay is active with the following logic:
In the example, digital input ID8 is configured as a high pressure switch
on circuit 1, label “o”, active with contact OPEN.
In the example, digital input ID8 is configured as a high pressure switch
on circuit 1, label “c”, active with contact CLOSED.
Display labels meaning noL (no link signalling)
Cause of trip Incorrect connection between remote terminal and controller or two remote
terminals configured as present and both with same HW address (see position of
keypads address assignment switch)
Reset Correct connection - two different HW addresses
Reset Automatic
