LMV51 Software Update: Version 0250 to 0510 (continued)
18. When using gas with the flue
gas recirculation function (FGR) and oil without the FGR
function, switchover to oil will not occur until the FGR actuator is closed.
19. When the air rate is adjusted, the message Ramp time too fast "actuator name" now
appears.
20. The setting range for the valve proving test times (phases 81 and 83) were increased from
63 seconds to 63 minutes.
21. Only on LMV51.1 – Other values other than the load are now available from analog output
X63.
LMV51 Software Update: Version 0510 to 0520
The following update was made with LMV5
2 software version 0520:
1. Expansion for SQM45 / SQM48 actuators with new parameter Pos. tolerance for changing
the tolerance of the actuator position and VSD speed.
Load Controller Software Update: Version 0140 to 0150
The following updates were made with L
MV5 load controller software version 0150:
1. An auxiliary sensor can be added for cold start thermal shock protection.
2. Straightforward changeover of operation to internal load controller mode (IntLC). Using a
potential-free contact at terminals X62.1 and X62.2, it is now possible to switch from other load
controller modes to the internal load controller mode. The following operating modes can be
switched over:
• IntLC X62 (mode 4) → IntLC (mode 2)
• ExtLC X62 (mode 5) → IntLC (mode 2)
• IntLC Bus (mode 3) → IntLC (mode 2)
• ExtLC Bus (mode 6) → IntLC (mode 2)
• ExtLC X5-03 (mode 1) → IntLC (mode 2)
3. Pt100 sensors in operating mode ExtLC Bus (mode 6) are now permitted.
4. New load controller functions for analog input and load output:
Manipulated variable input, modulating
• < 3 mA: Line interruption
• 4 mA / 2 Vdc: Low fire (minimum load)
• 20 mA / 10 Vdc: Nominal load (maximum load)
