flashes, follow this troubleshooting se-
quence:
1) Investigate the alarm (Sections 3.8, 3.9).
2) Do a self test with the load(s) connected.
3) If it passes the self test, see that the
load(s) are operating normally.
4) See the troubleshooting chart in Section
5.2.
5) Contact Alpha Technologies’ technical
support department
If the unit is overloaded, recalculate the
size of the load (Section 2.1).

Turn on the upstream circuit breaker.
Within 30 seconds the ATS switches back
to line power.
The Output LED is on and the display
shows “LINE.”
