PUMP_VIB_TEMP_MON
Bearing vibration and temperature supervision on two stages each, with start blanking, release hysteresis and a rate-of-rise alarm that sees a seizure before the absolute limit does.
When to use it
Use PUMP_VIB_TEMP_MON when a pump carries bearing vibration and temperature instrumentation and the station wants a warning early enough to plan a bearing change, plus a trip late enough to be believed.

Supervised control write
PUMP_VIB_TEMP_MON commands a real actuator. It is written to sit underneath your own interlock, permissive and protection logic — not to replace it. Commission it as you would any control block you wrote yourself.
