If there is no communication between the
pCO board and the GR3 boards, the GR3
boards will stop the compressors in 120".
No alarm will be shown, but on the UART
the number of data exchange will falls to
0 (to access the menu, on the GR3 board
menu press the screwdriver key for 5").

8.2 Guasto sonde di regolazione
Se le sonde (SAC della master se regolazi-
one in uscita o SIW della master se rego-
lazione in ingresso) assumono un valore
fuori dal range –32°C + 90°C il termostato
automaticamente viene forzato a 0 e tutti i
compressori vengono spenti. Solo in caso di
guasto alla sonda SIW (indipendentemente
dalla regolazione ) viene visualizzato a dis-
play della scheda master l'allarme e di con-

8.2 Riassunto allarmi globale
Sulla scheda pCO è presente un relè per il ri-
assunto allarmi globale (RA) delle macchine.
Se interviene uno dei due RA delle schede
GR3 allora anche quello della scheda pCO
interviene. L'uscita della scheda è NO8.
