Lmv52 Version 0510 To 1020; Lmv52 Version 1020 To 1030; Load Controller Version Updates - Siemens LMV5 Series Technical Instructions

LMV Series
The following updates were made with LMV52 software version 1020:
1. New function: Temperature-compensated flue gas recirculation (FGR).
2. Driving to the low fire position from phase 50 is adjustable (DriveLowfire Gas, DriveLowfire
Oil).
3. Extended monitoring of the air pressure switch with new mode "deactInStby". When using
this setting, the signal of the air pressure switch in standby is not evaluated. In case of
continuous purging, only a start prevention is triggered and a message appears in place of a
shutdown.
4. Extended monitoring of the air pressure switch for flue gas recirculation (FGR) with two new
modes:
deactInStby - When using this setting, the signal of the air pressure switch for flue gas
recirculation (FGR) in standby is not evaluated. In case of continuous purging, only a start
prevention is triggered and a message appears in place of a shutdown.
PS VSD - When using this setting, the pressure switch for flue gas recirculation (FGR) must
deliver an ON signal if the VSD speed lies above the speed set via parameter SP VSD PS on.
If the VSD speed lies below the speed set via parameter SP VSD PS off, the pressure switch for
flue gas recirculation (FGR) must deliver an OFF signal.
1. Specially designed for fiber mesh burners, various new start options have now been included
for O control and can be set via the Startmode parameter.

2. Long postpurge time (tn3) can be set up to 65,535 minutes via parameter PostpurgeT3Long.
The following update was made with LMV52 software version 1030:
1. Expansion for SQM45 / SQM48 actuators with new parameter Pos. tolerance for changing
the tolerance of the actuator position and VSD speed.
All load controller version updates to the LMV52 were the same as the updates for the LMV51.
See pages 6-8 in this section for details on the load controller software updates.
