74 GC250 Technical Manual
EAAM057608EN
Starting battery voltage, engine rotation speed, coolant temperature, oil pressure and
engine fuel level.
Each record is associated with its date/time. The measurements that are not acquired
(because the controller is configured not to acquire them) are replaced by some display
hyphens.
To display all records, the controller uses four pages of the display. The main page has the
following format:
The second line of each page shows what record is currently displayed (29) and any partial
record stored (40). Once the total number of records available is reached, the partial value will
remain fixed at the limit value up to a possible log resetting. The example in the previous figure
shows record 29 of 40 stored (out of 42 available).
The fourth line of each page displays the date/time of the record; on the right it also displays
two arrows indicating the availability of further pages to the right or to the left of the current
page for the current record.
The lines from the fifth to the eighth show different information, depending on the selected
page.
The first page displays all the values of the mains/bars, at the time of recording:
frequency and voltage
The second page displays all the values of the generator, at the time of recording:
frequency and voltages
The third page displays all the values of the load, currents and powers, at the time of
recording: currents, apparent power, active and reactive power, power factor.
The fourth page displays all the values of the engine, at the time of recording: battery
voltage, Engine speed oil pressure, Oil pressure, Coolant temperature, Fuel level
The more recent record is the one associated to the highest number. Using the ▲ and
▼ push-buttons it is possible to scan all the records
.
Keeping button ▼ pressed, the navigation through the pages linked to the single record
activates (the number that identifies the event e the number of the recorded records
begin to flash). At this point, using the ▲ and ▼ push-buttons it is possible to cyclically
scan all the pages. To
select another record keep ▲ pressed.

Fast analogues logs(
)
The fast analogues are recorded at a pace configurable by means of parameter
P.0442
(interval in seconds) and the default interval is 60 seconds. This archive have can store up to
42
42 records. Every following record overwrites the older one. The controller records the
analogue values described in par. 0.
7.4.9.5
Slow analogues logs(
)
The slow analogues are recorded at a pace configurable by means of the parameter
P.0443
(interval in minutes) and the default interval is 30 minutes. This archive have can store up to
H.15 OFF .
