LMV51 Software Update: Version 0250 to 0510 (continued)
2. The flue gas recirculation (FGR) pressure switch input X4-01.3 can be parameterized to not
care in standby mode.
3. New configuration of load controller inputs X5-03.2 and X5-03.3 to act like an LMV3 via
parameter
Config X5-03 .
4. Connection of a pressure switch for valve proving (PS-VP) or POC.
5. Configuration of input X9-03.4 via parameter GasPressureMin can be set to “deact xOGP” to
deactivate the input when firing oil.
6. Heavy oil direct start input X6-01.3 with more minimum temperature supervision options
(phases 21-62, phases 38-62).
7. Air pressure supervision can be deactivated in standby mode by setting parameter
AirPressureTest to “ deactInStby ”.
8. Option to adjust the reaction time for loss of flame and the safety time in operation via
parameter
ReacTmeLossFlame .
9. Configuration of input X5-03.3 via parameter Config X5-03 to stop the startup sequence in
phase 36 (driving to ignition position).
10. Using an air actuator and gas control valve, all modulating gas fuel trains can now also be
used for burners with pneumatic or mechanical fuel air ratio control.
11. Parameter StartPoint Op available for setting which curve point the LMV5 drives to after
lighting off.
12. Using parameter
DriveLowfire Gas(Oil),
drive to low fire may now start in phase 50.
13. Phases 50 and 52 are skipped if a non-pilot fuel train has been selected.
14. Manual output is unaffected by the load setting when programming the curve parameters,
both via the AZL5 and Modbus.
15. With an external load controller at input X5-03, the integration time of the input signals is
now established as a function of the ramp time.
Examples:
•
For a 30-second ramp time, there will be a load increase of approx. 0.6% per cycle
•
For a 60-second ramp time, there will be a load increase of approx. 0.3% per cycle
16. The minimum actuator step also applies when operating via Modbus or eBus remotely in
order to protect the actuators.
17. Quick shutdown in multistage operation with a variable speed drive (VSD) is only
performed if speed deviations are present that are above the parameterized threshold
TolQuickShutdown .
