SIEMENS OIL BURNERS AUTOMATIC CONTROLLER LMO24 -
LMO44
The LMO... burner controls are des igned for the start-up and supervision
of single- or 2-stage forced draught oil burners in intermittent operation.
Yellow-burning f lames are supervise d with p hotoresistive detectors
QRB..., blue-burning flames with blue-flame detectors QRC...
In terms of ho
using dimensions , elect rical co nnections and flame
detectors, the LMO... are identical to the LOA... oil burner controls.
Preconditions for startup
z
Burner control is reset
z
All contacts in the line are closed
z
No undervoltage
z
Flame detector is darkened, no extraneous light
Undervoltage
z
Safety shut-down in the operating position takes place sho uld the
mains voltage drop below about AC 165 V
z
Restart is initiated when the mains voltage exceeds about
AC 175 V
Time supervision oil pre-heater
If th e oil pre-heate r’s release contac t does not close within 10 minutes,
the burner control will initiate lock-out.
Controlled intermittent operation
After no more than 24 hours of cont inuous operation, the burner control
will initiate an automatic safety shut-down followed by a restart.
Control sequence in the event of fault
If lock-out occurs, th e outpu ts for the fuel va lves and the ignition will
immediately be deactivated (< 1 second).
Lock-out
In the event of lock-out, the LMO... remains locked (lock-out cannot be
changed), and the red signal lamp will light up. This status is also maintai-
ned in the case of a mains failure.
Resetting the burner
Whenever lock-out occurs, the burner control can immediately be reset.
To do this, keep control the lock-out reset button depressed for about 1
second (< 3 seconds).
Ignition program with LMO24.113A2
If the flame is lost during «TSA», the burner will be reignited, but not later
than at the end of «TSAmax.». This means that several ignition attempts
can be made during TSA (refer to «Program sequence»).
Limitation of repetitions
If the flame is lost during operation, a maximum of 3 repet itions can be
made. If the flame is lost for the 4th time during operation, the burner will
initiate lo ck-out. T he rep etition count is re started each time controlled
switching on by «R-W-SB» takes place.
Operation
Lock-out reset button «EK...» is the key operatin g element for
resetting the burn er control and fo r activating / deactivating t he
diagnostic functions.
The multicolour «LED» is the key indicating element for bo th
visual diagnosis and interface diagnosis.

Diagnosis of cause of fault
After lock-out, the red fault signal lamp remains steady on.
In that condition, the visual diagnosis of the cause of fault according to the
error code table can be activated by pressing the lock-out reset button for
more than 3 seconds.
Cause Response
After a mains failure Restart
After voltage has fallen below the
undervoltage threshold
Restart
In the event of a premature, faulty
flame signal during «t1»
Lock-out at the end of «t1»
In the event of a premature, faulty
flame signal during «tw»
Prevention of start-up, lock-
out after no more than 40
seconds
If the burner does not ignite during
«TSA»
Lock-out at the end of TSA
In the event the flame is lost during
operation Max. 3 repetitions, followed
by lock-out
Oil pre-heater’s release contact does
not close within 10 min.
Lock-out
