8.18 Alarm history
All recipes
On the SMART-MT, in addition to displaying the active alarms (AL menu),
you can view the history of the last 10 alarms (000 menu).
The instant an alarm appears, the following is saved:
- the alarm code (Par LAL0),
- the date (Par LAL1),
- the hour (LAL2 pair)
- external air temperature (LAL3)
- the temperature of the water entering the PdC (LAL4)
- the temperature of the water leaving the PdC (LAL5)
- the electrical power absorbed by the PdC, if available, otherwise Com-
pressor operation step (LAL6).
On the CAL0 Parameter, select the chronological position (from 0 to 9)
that you want to consult, then view the saved data (LAL0 ÷ LAL6).
