Warning alarms

[whrdnsx]

I have set all my sensors with Alarms like Oil pressure, temps ect.
But for some reason while the engine is off & i'm just in Adjust. I have a Water pressure sensor
configured in User channels & it sets of the alarm every ten or so seconds. (which it should if under the lo value)
Yet none of the other sensors will set an alarm like Oil pressure with the engine not running?

Everything is working fine. & settings are correct.
It's just a pain having to clear the warning while i'm making adjustments.
Am i missing something. is there a rpm threshold in Engine sensors & not in User sensors?

Thanks.
