6- Assignment of alarm output terminals
Once an alarm is detected, the alarm output contact changes over.
By setting the alarm output terminals, monitoring of many different operations is enabled. Each setting functions by
changing the parameters AS and Ao
Before supplying power to COOLCABI, both of terminals - and -3 are open. The time lag between power input
and the changeover of the terminals is .8 seconds.
Monitoring of alarm occurrence [AS： ]
The state of alarm output terminals changes by alarm occurrence regardless of whether cooling operation is
performed or not.
Monitoring of cooling operation and alarm occurrence [AS： ]
The state of alarm output terminals changes responding to the state of cooling operation and alarm occurrence.
3 Identifying alarms that require power input and alarms that do not [AS： ]
The state of alarm output terminals changes responding to the alarms E , E3, E4, E6, E7 S , S , S3 and S4
that are restored automatically or manually and the alarms E5, E8, S5, tE and SE that require power
reconnection.
4
Identifying alarms that continue cooling operation and alarms that do not
The state of alarm output terminals changes responding to the alarms E , E4, S , S , S3 and S4 that continue
cooling operation and the alarms E3, E5, E6, E7, E8, S5, tE and SE that do not.
*Cooling operation means the state that the compressor is working and cool air is being output from the discharge port.
