Auto Restart
The line voltage is outside the tolerance band at
the moment (e.g. power outage). The firing pulses
are therefore inhibited. On power recovery,
however, the WEA option (P366) implements an
auto restart.
Important
An auto restart may constitute a danger for persons and
property. Make sure you really want to have auto restart
(WEA).
If necessary, change
P366 WEA.
