4.2 Actuator doors configuration
After the adressing of the actuators, it is necessary to activate and to configure the operation way for each servomotor.
ATTENTION: Activate only the actuators that are really present, otherwise an error will occur.

VSD = VSD only
AUX3 = FGR only, without temperature compensation
VSD+AUX3 = VSD and FGR
LMV 51.300 has the possibility to operate with VGD+FGR without temperature compensation
4.3 Setting the actuator speed
LMV sees VSD as an actuator, that’s why the speed ramp up and the stop times must not be higher than the actuator stroke time. If it is necessary to
increase the VSD times, change the actuator stroke time also, according to the next procedure. By following the next table, set both parameter
“OperatRampMod” and “TimeNoFlame” to set the ramp up/stop times for the VSD and the actuator opening speed (from 0° to 90°).

Times
OperatRampMod Service 40 s Operating ramp modulating is the
maximum speed of the actuators during
operation (phase 60 ÷ 62).
A setting of 30 seconds generates a
maximum speed of 90° in 30 seconds
(3°/s).
The LMV5 calculates an individual
speed for each actuator, so that all
actuators reach their target positions at
the same time.
Range 10..60s
TimeNo- Flame Service 40 s Drive ramp is the speed of the actuators
when traveling to the home, prepurge,
ignition, and postpurge positions.
A setting of 10 seconds generates a
maximum speed of 90° in 10 seconds
(9°/s).
Range 10..120s
ATTENTION: It is suggested to set the ramp up and stop time to a value about 35% lower then the slowest actuator.
