Discharge protection trip.

The rack's discharge protection has tripped after its configured trip setpoint and delay — a protective shutdown that takes the whole rack offline and puts every case it feeds at risk simultaneously. The highest-urgency rack event.

01 Detail

Trigger, action plan, and escalation criteria.

Related metric: refrigeration_rack_discharge_pressure
Trigger: discharge protection trip after Disch Trip Stpt / Disch Trip Dly (trip state confirmed)
Value drivers: Operational continuity Product loss prevention Asset lifespan
Preconditions: Rack controller exposes the trip state and Disch Trip Stpt / Disch Trip Dly; feed health confirmed.
Human role: Primary — immediate dispatch and store/customer-ops communication; AI confirms the trip and assembles evidence.
Action plan: (1) Confirm the trip state and time from the controller and whether the rack is down or in an auto-reset attempt. (2) Raise the rack-loss product-risk path immediately — every case on the rack is now at risk. (3) Assemble the pre-trip discharge trend and any correlated cause for the vendor. (4) Dispatch the refrigeration vendor immediately with the evidence; recommend a product check per category as warranted.
Escalation: (1) Trip with no successful auto-reset → immediate emergency dispatch and store/customer-ops alert. (2) Trip recurs after reset → do not rely on auto-reset; escalate as a hardware/controls failure.
Prevention: (1) Act on the discharge high-pressure and trip-approach alarms upstream so a trip is the exception, not the first signal. (2) Calibrate Disch Trip Stpt / Disch Trip Dly per rack and review recurring trips as replacement candidates.
