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 dierential
— PD: wait for PullDown
