A chiller status alarm can be a chiller on-alarm or a chiller off-alarm.
A chiller on alarm is generated when the chiller is commanded off and the status is on after the time delay defined by ALM-05. The chiller on alarm is automatically reset. The chiller module is able to start up if a chiller on-alarm is active.
A chiller off alarm is generated when the chiller is commanded on and the status is off after the time delay defined by ALM-05. The chiller off alarm must be reset (manually or automatically)
The chiller on alarm is displayed by DISP-10.
The chiller off alarm is displayed by DISP-09.
The chiller status alarm is displayed by DISP-05.
