2. Menu level 3 - enter on «GasSettings» or «OilSettings»
Note: The settings below have to be adjusted for all fuels which are actually used
3. Menu level 4 - enter on «Special Positions»
4. Menu level 4 - enter on:
* Home pos. (set - «HomePosVSD» = 0 %)
* Prepurge pos. (set - «PrepurgePosVSD» = 100 %)
* Ignition pos. (set - «IgnitionPosVSD» = 50 %)

VSD module
1. Menu level 1 - enter on «Params & Display»
2. Menu level 2 - enter on «VSD Module»
3. Menu level 3 - enter on «Configuration»
4. Menu level 4 - enter on «Speed»
5. Menu level 5 - enter on:
* Num pulse per R = 3 - default
* Setpoint output = 4…20 mA - default (must match analog input setting in VSD)
* Standardization = activated
Note: During «Standardization», the LMV5… will first drive the air damper fully open and then drive
the VSD to full frequency to obtain maximum motor SPEED, which is stored under parameter
«Standardized Speed».
Note: During «Standardization», the LMV5… you can check the correct mounting of the feedback sen-
sor.
1. Back to menu level 4 – ESC
2. Back to menu level 3 – ESC
3. Menu level 3 - enter to «Process Data»
4. Menu level 4 - enter to «Absolute Speed»
5. The maximum speed should not vary more than 5 rpm during 10 seconds
Note: It is important to set the MM440 «ramp-up & ramp-down» times less than the times set in
the LMV5… parameters «OperatRampMod» & «TimeNoFlam».
(i.e. LMV5… times = 50 seconds - VSD ramp times = 40 seconds)
