on the top left corner of the screen. When pressed, a popup confirming that the
screenshot has been saved on the SD card appears. These screenshots can then
be retrieved from the SD card for record keeping purposes.
10.0 MANUAL MODE
10.1 To manually start the engine, press the RESET button. The TIMERS ACTIVE
message will be displayed and remains until all Class B and Class C inputs have
been armed. During the time that the Class B and Class C timers are still active,
manually purge and crank the engine.
11.0 AUTO START
11.1 To automatically start the engine, AUTO START must be selected during pro-
gramming and the starting procedure sequence must be defined.
11.2 STATE 0: SHUTDOWN
The AUTO START sequence must begin from an engine stopped condition, this
means that the measured RPM has been at zero for at least 5 seconds. This is
the system STATE 0 on the sequence chart.
11.3 STATE 1: BEGIN AUTO START SEQUENCE TIMED DELAY PERIOD
When the auto start command is received, the first action taken is to create
an internal system reset which clears the previously set fault flags and resets
the PRE-LUBE (Timer 1) and DELAY BEFORE CRANKING (Timer 2) timers to
a count of zero. This is system STATE 1. The PRE-LUBE and DELAY BEFORE
CRANKING timers will both begin counting at this time, but they each have an
independently set value so that the PRE-LUBE pump can be set to run prior to
the cranking only or thru the cranking cycle or until some point in time after the
engine starts. If an optional pressure setpoint is going to be used to terminate
the PRE-LUBE operation, this can be done by using a secondary control setpoint
on oil pressure assigned to one of the discrete control outputs. In system STATE
1, while these timers are running, all class A setpoints are being monitored and
if any of these monitored points fault, the auto start sequence will be termi-
nated and the cause of the fault displayed, returning the unit to system STATE
0 on the sequence chart. If no faults are present during system STATE 1, the
DELAY BEFORE CRANKING timer continues to count until the selected value
is reached. In system STATE 1 of the sequence the system turns on the power
NOTE: AUTO START IS INHIBITED BY
SENSING ANY RPM ABOVE 0 RPM.
AUTO START IS ABORTED BY THE
DETECTION OF ANY MONITORED FAULT.
CLASS B AND CLASS C TIMERS BEGIN
AT CRANKING. A LOCAL WARNING
SIGNAL AT THE ENGINE SITE PRIOR TO
CRANKING SHOULD BE PROVIDED.
NOTE: IF A CLASS A SETPOINT SHOULD
FAULT AT ANY TIME DURING AN AUTO
START SEQUENCE, THE SYSTEM WILL
TERMINATE THE SEQUENCE AND
DISPLAY THE APPROPRIATE FAULT
MESSAGE RETURNING THE SYSTEM TO
STATE 0.
