22.2.1.10 Basic unit LMV51.0 and LMV51.1, Software from V02.50 to V05.10

With the 2012/2013 release upgrade for the LMV5, the microcomputer PCB in the
variants named above will be converted to the same microcomputer PCB as in the
LMV51.3 and LMV52 (known as platform conversion).
This means that from the date of the switchover, these variants will also have the
additional hardware input X7-03 pin 2 (start release gas or CPI), which was previously
only available for the LMV51.3 and LMV52.
Additionally, the assignment of the software functions to the LMV5 variants has also
been rearranged, meaning that the release upgrade includes functions from higher
LMV5 variants as well as completely new functions:
1. Configuration of new input X7-03 pin 2 for start release gas or for various valve
closure contact via parameter StartReleaseGas, refer to chapter Start release - gas
/ CPI
2. Flue gas recirculation pressure switch (X4-01 pin 3) can be parameterized to don´t
care in standby mode.
Configuration of input X4-01 pin 3 via parameter FGR-PS/FCC, refer to chapter Fan
contactor contact / flue gas recirculation pressure switch
3. Configuration of load controller inputs X5-03 pin 2 and X5-03 pin 2 via parameter
Config X5-03.
This enables the same input function as in the LMV2/LMV3 to be achieved, refer to
chapter External boiler controller OPEN/CLOSED or STAGE2 / STAGE3
4. Connection of a pressure switch for valve proving (PS-VP) or valve closure contacts
(CPI). Configuration of input X9-03 pin 2 via parameter PS-VP/CPI, refer to chapter
Gas pressure switch - valve proving or valve closure contacts (X9-03 pin 2)
5. Configuration of input X9-03 pin 4 via parameter GasPressureMin.
deact xOGP setting available (for deactivating LOgp and HOgp), refer to chapter
Gas pressure switch-min (X9-03 pin 4)
6. Heavy oil direct start X6-01 pin 3 with minimum temperature supervision in phases
21...61 and 38...62, refer to chapter Heavy oil - direct start (X6-01 pin 3)
7. Air pressure supervision can be deactivated in standby mode, refer to chapter Air
pressure switch (X3-02 pin 1)
8. Option to adjust the reaction time for loss of flame and also the safety time in
operation via parameter ReacTmeLossFlame, refer to chapter Reaction time for
loss of flame / safety time in operation
9. Startup stop (start/stop in phase 36).
Configuration of input X5-03 pin 3 via parameter Config X5-03, refer to chapter
Startup sequence stop in phase 36
10. In connection with an air actuator and gas control valve, all gas fuel trains
(modulating) can now also be used for burners with pneumatic or mechanical fuel-
air ratio control ⇓ actuators can be deactivated, refer to chapter Activating /
deactivating the actuators
11. Parameter StartPoint Op available, refer to chapter Startpoint operation
12. Approaching low-fire starting in phase 50, refer to chapter Approaching low fire in
phase 50 / 54
13. Skipping phases 50 and 52 if a non-pilot fuel train has been selected, refer to
chapter Sequence diagrams
14. Manual output should be unaffected by the load for setting the curve parameter,
block the impact of the value when setting curve parameters via Modbus.
15. With an external load controller at input X5, the integration time of the input signals
is now established as a function of the ramp time.
Examples:
- For 30-second ramp time,  load increase of approx. 0.6% per cycle
- For 60-second ramp time  load increase of approx. 0.3% per cycle
16. The minimum actuator step should also apply when operating the Modbus and
eBus remotely in order to protect the actuators, refer to chapter Settling of the
manipulated variable
