Siemens LMO 39.100 C2

Siemens LMO39 automatic burner controls are used to commission and monitor 1-stage or 2-stage forced draught oil burners in intermittent operation. Flame monitoring takes place with a yellow burning flame with photo resistance sensor QRB1 / QRB3 or yellow flame sensor QRB4, with a blue burning flame with blue flame sensor QRC1.

Applications according to EN 267: Gas burners for liquid fuels
• Type-tested and approved according to DIN EN 298
• Undervoltage detection
• Electrical remote release
• Bypass contact for oil preheater
• Precise and reproducible program times thanks to digital signal processing
• Controlled intermittent operation after 24 hours of uninterrupted operation
• Restart limitation
• Multicolored display of fault messages and operating messages
• BCI interface
• For stationary hot air heaters
• Time monitoring for oil preheaters

Default setting:
tw max = 2.5 s
TSA(P267) max. 5 s
t1(P265) min. 0 s
t3 (P266) min. 30 s
t3n(P295) approx. 4.5 s
t4(P270) approx. 5 s
t8(P274) min. 0 s
tow(P296) approx. 600 s

Note on parameterization:
The AZL2 or ACS410 is always used to set the exact value of the desired time (a multiple of the increment of 0.147 seconds, 0.294 seconds or 4.851 seconds). When parameterizing minimum or maximum times, a possible tolerance of ±7% must be taken into account.
The following applies to a minimum value: A value that is at least 7% greater must be parameterized. The following applies to a maximum value: A value that is at least 7% lower must be parameterized.

Scope of delivery:
Only the automatic burner control unit is supplied! The ACS410 software or the AZL2 display and control unit must be ordered separately if required.
