START and STOP keys – These work in MAN operating
mode only, used to start and stop the engine. By quickly
pressing the START key, one start attempt takes place; by
keeping the START key pressed, the duration of the start
attempts can be extended. The flashing LED of the engine
symbol denotes engine started, with alarms inhibited; and is
constantly on at the end of the alarms inhibition time. The
engine can be stopped using the OFF/RESET key.
MAINS and GEN keys – They work in MAN operating mode
only, used to switch the load from mains to generator and vice
versa. The illuminated LEDs of the mains and generator
symbols indicate the respective voltages are within preset
limits. The illuminated LEDs of the changeover symbols indicate
the actual closing of switching devices; when flashing, there is
a incorrect feed-back signal for the actual closing or opening
of the switching devices.
OPERATING MODE
OFF/RESET mode – The engine can not operate. If the mains
is present, the load is switched to the mains. Changing from
TEST, AUT or MAN to the OFF/RESET mode and if the engine
is running, the engine is immediately stopped and eventual
alarms are reset. If the cause of the alarm is still present, it can
not be reset.
MAN mode – The engine can be manually started or stopped
using the START and STOP keys only in addition to load
switching from mains to generator and vice versa, by means of
the MAINS and GEN keys. Always in MAN mode, at the start
command and by keeping the key pressed, the preset starting
time can be prolonged while at the stop command and by
keeping the key pressed for more than 6 seconds, the fuel
valve is discharged for 4 minutes.
AUT mode – In case of mains not present (out of the preset
limits), the engine automatically starts or stops when the
mains returns.
TEST mode – The engine immediately starts even if the
mains is present. In case the mains is not present, the load is
switched to the generator. Changing to the AUT mode and if
the mains is present, the engine will stop.
Alarms
When an alarm arises, the lower section of the display is used
to view it. In case of two alarms or more, they are individually
shown in sequence. A help message is available for every
alarm, in order to locate the possible alarm source. Alarm
conditions can be reset by means of the OFF/RESET key, that
prevent any unintentional engine starting at the alarm reset
operation. If the alarm does not reset, this means the cause of
the alarm is still present. During event-log sessions and set-up
operations, no alarms are viewed.
