14 INPUT/OUTPUT MENU
This menu is used to display the state of the inputs and outputs, both digital as well
as analogue.
The rst mask, which is present only in the master card parameters, summarises
the machine status with a graphic indication of the compressor power (no. capacity
controls), input temperature, master water output and circuit operating status.

This mask displays:
1. In: water inlet temperature (master)
2. Out: water outlet temperature (master)
3. Cooling capacity of the compressors present from 1 to 4, expressed as a
percentage
4. Status indication of circuits from 1 to 4:
— ok: operative
— al: stopped due to alarm
— ---: No present
— sp: safety reducer
— WW: wait for safety dierential
