The unit frstly checks if SW1 is ON. If it is then the unit activates the preheat output for 4
secs. This happens before every start attempt. This enables the connection of preheat relays for
engines that use them.
It makes up to fve start attempts. If the engine didn't start after the last attempt, the unit
locks with the message
'ERROR: START FAILURE'
. At the same time the display blinks and the
siren output is activated and deactivated intermittently.
In any case of error lock, the mode switch must go to OFF-RESET for a short time and then
back to AUTO for the unit to be in normal automatic operation again.
With every start attempt a message:
'STARTING 1' 2,3
,
etc. Is displayed, and in between
start attempts
'WAIT...'
is displayed. As soon as the engine starts
'ENGINE RUNNING'
is
displayed temporarily, and then the display shows the hours counter on the top line, and rolling
bars below signifying error-less operation.
The total time the engine has operated, is measured and recorded with 1 minute resolution.
This can be reset to zero by setting temporarily Dip Switch 2 to ON, when the unit is in AUTO and
is operating normally -e.g. not locked by an error. This can be used to indicate time from last
service.
Error monitoring starts 15secs after the engine has started, so it is possible to protect the
equipment from great damage. In any error case, the engine stops, the unit locks so the user will
see witch error took place, indication
'ERROR:'
is displayed, followed by the corresponding
message:
OIL PRESSURE – HIGH TEMPERATURE – BELT BREAK – FUEL LEVEL
When engine is running and the contact in terminals [10] and [11] opens again, the engine is
stopped and everything returns to idle state.
TEST Mode
: In this mode the user can check the condition of the batteries as follows: With
the mode switch in AUTO and while in idle state, TEST button is pressed for 4 secs. The message
'TEST START / MANUAL OFF'
is displayed on screen and then the units makes start attempt after
start attempt but without letting the engine to start. The battery is good if fve start attempts are
made with no hesitation. Test mode is exited by switching the mode switch to OFF.
Preheat
: When the engine requires DC preheat, terminal 14 is used. Injector preheat resistors
are connected there through a suitable dc relay. The dip switch SW1 must also be set to ON
position. Now before each start attempt, the message "Preheat" will be displayed and the resistors
will be powered for a short while. The start attempt will begin as soon as preheat operation ends.
Adjustments
: If the engine switches of by pulling an electromagnet, we need to adjust the
small trimmer located below the terminals. This controls the switch of time. This time should be
enough for the engine to stop but not too much, because solenoids of this type are usually
designed to operate for short times.
