6.6.3 Cycling Shutdowns
If the chiller shuts down on a CYCLING shutdown,
the chiller will automatically restart when the cycling
condition is removed. These shutdowns do not require
the operator to manually reset the control centre prior
to restarting the chiller.
Common Shutdowns
Multi-unit Cycling – Contacts Open
System Cycling – Contacts Open
Oil – Low Temperature Differential
Oil – Low Temperature
Control Panel – Power Failure
Leaving Chilled Liquid – Low Temperature
Leaving Chilled Liquid – Flow Switch Open
Condenser - Flow Switch Open
Motor Controller – Contacts Open
Motor Controller – Loss of Current
Power Fault
Control Panel – Schedule
Proximity Probe – Low Supply Voltage
Oil – Variable Speed Pump – Drive Contacts
Open
