Repeated discharge resets.

The rack's discharge protection auto-resets repeatedly, or trips recur after the configured auto-reset — a rack running on the edge of its protection band that masks a developing fault behind automatic recovery.

Trigger, action plan, and escalation criteria.

optimization_metric refrigeration high managed tier AI: hybrid

Related metric: refrigeration_rack_discharge_pressure
Trigger: repeated auto-resets or recurring trips after Disch Auto Rst within the commissioned observation window
Value drivers: Operational continuity Asset lifespan Energy savings
Preconditions: Rack controller exposes trip/reset events and Disch Auto Rst; feed health confirmed; observation window commissioned per rack.
Human role: Primary when a dispatch is required; AI detects the reset pattern and correlates.
Action plan: (1) Confirm the repeated-reset pattern from trip/reset events over the commissioned observation window. (2) Do not treat a successful auto-reset as resolution — a repeating cycle is a developing fault. (3) Correlate with discharge-pressure trend and condenser state for the underlying cause. (4) Dispatch the refrigeration vendor with the reset history before a reset fails to recover.
Escalation: (1) Reset frequency rising, or a reset that fails to recover → urgent dispatch and store/customer-ops alert. (2) Repeated resets on the same rack across periods → hardware/controls review candidate.
Prevention: (1) Alert on the reset pattern rather than the individual trip so a masked developing fault is surfaced. (2) Calibrate Disch Auto Rst and the observation window per rack; review recurring-reset racks at the MBR.
