Message Status
Overload Detected
An overload is present.
▪
When the PX3TS device detects an overload
condition on the outlet, it shuts down the outlet
completely to protect the inlets.
▪
The state of the switch remains off as long as the
overload alarm is present.
▪
The load will restore power after performing both
actions below:
▪
Resolve the overload problem.
▪
Manually clear the overload alarm by
performing a manual transfer. To clear the
alarm, see
Manual Transfer When an Alarm
is Present (on page 114).
Internal Fault
A switch open or switch short fault is detected on the
Inlet 1/2 switch.
Note: In the "off" state, neither inlet on the Transfer Switch page shows the
icon.
Inlet Phase:
Field Description
Inlet Phase Sync
Indicates whether the phase angles of both inlets
are in synchronization or not.
•
in sync : The inlets are in synchronization
when their phase angle difference does NOT
exceed 15 degrees.
•
out of sync : The inlets are out of
synchronization when their phase angle
difference is over 15 degrees.
The 15-degree threshold is not
user-configurable, and it is not related to the
warning/critical thresholds of the 'Inlet Phase
Angle' sensor.
Inlet Phase Angle
Indicates the value of phase angle difference,
which is the phase shift between the two inlets'
voltage signals.
