Timer
Description
Pre-heat
Give a ‘pre start’ time during which the
Preheat
output
and
Starting alarm
will become
active (if configured)
Pre-heat bypass
Should the set be stopped, the
Pre-heat
by
pass
timer begins.
Should
the set be called to
start again, before the timer expires, the pre-heat sequence is bypassed as heating is not
required since the set is still warm after the last run.
Cranking time
The length of each crank attempt
Crank rest time
The time between multiple crank attempts.
Engage Attempt time
(Only available if using Magnetic pick-up and multiple engage attempts)
This timer dictates the duration that the module will attempt to engage the starter motor
during each engage attempt. If the Magnetic Pick-up is not detecting movement of the
flywheel when this timer expires, the engage attempt will terminate. Once all engage
attempts have been made, the next start attempt begins.
Engage Rest Time
(Only available if using Magnetic pick-up and multiple engage attempts)
This timer dictates the duration that the module will wait between attempts to engage to
starter.
Delay Crank
(Only available if using Magnetic pick-up and multiple engage attempts)
This is the difference in time when the fuel relay energises and the crank relay energises.
Smoke limit
The amount of time that the engine will be requested to run at
idle
speed upon starting.
This is typically used to limit emissions at start up.
Smoke limit off
This should be set to a little longer than the amount of time that the set takes to run up to
rated speed after removal of the command to run at idle speed. If this time is too short, the
set could be stopped due to under speed failure. If the time is too long, under speed
protection is disabled until the Smoke limit time off time has expired.
Safety on delay
The amount of time at start up that the controller will ignore oil pressure, engine speed,
alternator voltage and other delayed alarms. This is used to allow the engine to run up to
speed before protections are activated.
Warming up time
The amount of time that the set will run BEFORE being allowed to take load. This is used
to warm the engine to prevent excessive wear.
Sensor fail delay
(Only available if using Magnetic pick-up)
This is only used if magnetic pick speed sensing is selected. Once cranking has
commenced the module must receive a speed signal within this time. If no signal is
present, the generator will be shutdown and a Loss of Speed Sensing alarm given.
