Parameter
Parameter 255
Min.speed for
ignit. 000 rpm
This screen is only visible if the
parameter "Pickup" is set "ON".
Gas engine; minimum start speed 0 to 999 rpm
L The minimum starter speed can only be detected if the magnetic pick-up
has been enabled (Parameter 280).
Once the ignition delay (Parameter 256) has expired, the engine m
ust exceed the
speed configured with this parameter in order to enable the ignition relay (relay
manager function 84).
Parameter 256
Ignition delay
00s
Gas engine; ignition delay 0 to 99 s
In gas engine applications a purging operation is frequently desired prior to start-
ing. The ignition delay is initiated when the starter is engaged. If this time has ex-
pired and the "Minimum speed for ignition" (Parameter 255) has been exceeded,
th
e ignition is enabled.
Parameter 257
Gasvalve delay
00s
Gas engine; gas valve delay 0 to 99 s
This timer is initiated once the ignition is enabled. Once this timer has expired and
the engine speed is at least 150 rpm, the gas valve is opened. Upon reaching the fir-
ing speed (Parameter 272) the relay remains energized until the engine stops.
Parameter 258
Max. attempts to
start 0
Gas engine; maximum number of start attempts 1 to 6
The control will initiate up to this number of start attempts. If the engine cannot be
started within this number of start attempts, an alarm message is issued.
Parameter 259
Starter time
00s
Gas engine; engagement time of the starter 2 to 99 s
The maximum amount of time the starter will crank the engine during a start se-
quence.
Parameter 260
Start pause time
00s
Gas engine; time between two start attempts 1 to 99 s
The delay time between the individual start attempts.
Parameter 261
f lower before
start ON
with three-step controllers only
only accessible via LeoPC1
Gas engine; frequency lower prior to start ON/OFF
If this function is enabled and the control is equipped with a three-step frequency
controller, the command "lower engine speed" is issued for the time configured in
Parameter 262 before the starter is engaged. The low-idle position m
ust either be
equipped with a limit switch or the engine potentiometer must be equipped with a
slipping clutch to protect the device once the lowest possible setting has been
achieved. A message is displayed while this function is active.
CAUTION
The engine starting is delay by means of the low-idle position in the event of emer-
gency power operation.
Parameter 262
time f lower
bef.start 000s
with three-step controllers only
only accessible via LeoPC1
Gas engine; frequency lower prior to start (time) 0 to 999 s
The duration that the "lower engine speed" signal (Parameter 261) is output.
