10-2: LMV51 Software Version Updates
This section covers all of the revisions t
hat were made to the LMV51 controller with each new
software release. The software version of any LMV51 controller can be found using the
following menu path:
Params & Display > BurnerControl > SW Version
The LMV51.1 also has a load controller with its own unique software version. The software
version for the load controller can be found using the following menu path:
Params & Display > LoadController > SW Version
LMV51 Software Update: Version 0210 to 0220
The following updates were made with L
MV51 software version 0220:
1. When the unit reaches the Program stop position, the AZL5 displays “Programstop active”.
2. Alarm output X3-02.1 can be deactivated via parameter Alarm act/deact. The current fault
or lockout is still maintained on the AZL, but the 120V output is de-energized. Deactivation of
the output remains active until a reset is made, another fault occurs, or a startup occurs.
3. A low oil pressure switch can now be activated when firing oil.
4. When firing oil, the oil safety valve output X6-03.3 de-energizes on completion of the
afterburn time (end of phase 70). The fan output de-energizes after phase 79. Using
parameter OilPumpCoupling, it is now possible to choose between the described above (when
using the magnetic clutch) or direct coupling of the oil pump. In the case of direct coupling, the
oil safety valve must be connected to the output for the oil pump (X6-02.3). The oil safety is
will always be controlled when the fan runs, plus another 15 seconds.
5. The evaluation of input DWminOil when using oil train “Heavy oil with gas pilot” has been
moved from phase 38 to phase 44. DWminOil is only valued during the safety time after a delay
time has elapsed.
6. The output signal to the air pressure switch test valve can be inverted using parameter
Start/PS-Valve. This output is only active when the fan operates.
7. If the burner operation is set to “Manually on”, the burner on / off contact (X5-03.1) acts as
a shutoff device should an over-temperature situation occur. With the exception of operating
mode 1 (ExtLC X5-03), the burner on / off contact can be deactivated if not being used as a
shutoff device.
