pending).The alarm relay (Mode 5 only) is automatically reset when the alarm disappears;
it can need a manual reset only for special value of P27 (Er4 & Er5) and of C29 (Er3) (see
the technical manual for details). In case of alarm type Er0, Er1, Er2 the normal function
of the unit restarts automatically when the alarm disappears; after a Er3 alarm the unit
restarts automatically or manually according to C29; Er4 & Er5 alarms do not affect the
normal function of the unit.
