Phase Loss Trip
Configure Phase Loss Trip in HPzenAi Smart. Trips a three-phase motor when any phase is missing.
What it does
Trip immediately if any phase is missing.
Trips a three-phase motor when any phase is missing. Use this automation when the selected field devices should work together without repeated manual setup.
Automation Logic
Trigger
A phase-loss condition is detected.
A phase is missing
Example: choose "A phase is missing" for the default when behavior.
Condition
The motor is running or allowed to start and phase monitoring is active.
No condition
Example: leave No condition selected when the trigger alone should run the workflow.
Action
Stop or block the motor and send a phase-loss alert.
Stop motor and alert me
Example: choose "Stop motor and alert me" for the default then behavior.
Allowed Time
Use All day for three-phase motor protection.
All day
Example: keep All day for protection workflows, or choose Day or Night when operation should stay inside site hours.
Automation Details
Recommended use
Three-phase pumps, starters, and panels with phase monitoring.
Motor Controllers, Energy Meters, Level Sensors
Stop or block the motor and send a phase-loss alert.
Do not restart until the electrical supply issue is corrected.
Verify phase readings during commissioning; do not intentionally remove a live phase for testing.
Before You Start
Device Readiness
Link every device used by this workflow and confirm each one is online.
Device Selection
Choose the exact tank, pump, valve, relay, or meter that should be controlled.
Safe Test
Test with safe thresholds or manual observation before leaving the workflow enabled.
Guided Setup
Set Up Phase Loss Trip
Open the HPzenAi app.
Commissioning Checks
- Confirm the motor action or alert follows the selected protection condition.
- Verify phase readings during commissioning; do not intentionally remove a live phase for testing.
- Confirm the saved card shows the correct workflow, devices, schedule, and enabled state.
- Review the event history after testing so the action is recorded as expected.
- Keep safety-critical workflows active all day unless the site needs a specific time window.
Troubleshooting
- If the Save button is disabled, complete every required trigger, condition, action, and timing field.
- If the workflow does not run, confirm the devices are online and the active time allows it to run now.
- If the action does not complete, check whether the target device is already in that state or cannot accept commands.
- If notification behavior is missing, confirm phone notification permission and recent device data.
