CONTROL PROGRAM IN THE EVENT OF FAULT
If a fault occurs, all outputs will immediately be deactivated (in less
than 1s).
After an interruption of power, a restart will be made with the full pro-
gram sequence.
If the operating voltage drops below the undervoltage thresold, a
safety shutdown is performed.
If the operating voltage exceeds the undervoltage thresold, a restart
will be performed.
In case of extraneous light during "t1", a lockout occurs.
In case of extraneous light during "tw", there is a prevention of startup
and a lockout after 30 seconds.
In case of no flame at the end of TSA, there will be max. 3 repetitions
of the startup cycle, followed by a lockout at the end of TSA, for mod.
LME11..; directly a lockout at the end of TSA for LME21-22 models.
For LME11 model: if a loss of flame occurs during operation, in case of
an establishment of flame at the end of TSA, there will be max. 3 repeti-
tions, otherwise a lockout will occur.
For LME21-22 models: if a loss of flame occurs during operation, there
will be a lockout.
If the contact of air pressure monitor LP is in working position, a pre-
vention of startup and lockout after 65 seconds will occur.
IIf the contact of air pressure monitor LP is in normal position, a
lockout occurs at the end of t10.
If no air pressure signal is present after completion of t1, a lockout will
occur.

RESETTING THE BURNER CONTROL
When lockout occurs, the burner control can immediately be reset, by
pressing the lockout reset button for about 1..3 seconds. The LME.. can
only be reset when all contacts in the line are closed and when there is no
undervoltage.
LIMITATION OF REPETITIONS (only for LME11.. model)
If no flame is established at the end of TSA, or if the flame is lost during
operation, a maximum of 3 repetitions per controller startup can be perfor-
med via "R", otherwise lockout will be initiated. Counting of repetitions is
restarted each time a controlled startup via "R" takes place.
Condensation, formation of ice and ingress of water are not
permitted!
CIB UNIGAS
CONTROL BOX LOCKED
In the event of lockout, the LME.. remains locked and the red signal lamp
(LED) will light up.The burner control can immediately be reset. This state
is also mantained in the case fo mains failure.
DIAGNOSITICS OF THE CASUE OF FAULT
Press the lockout reset button for more than 3 seconds to activate the
visual diagnostics.
Count the number of blinks of the red signsl lamp and check the fault
condition on the "Error code table" (the device repeats the blinks for
regular intervals).
During diagnostics, the control outputs are deactivated:
- the burner remains shut down;
- external fault indication is deactivated;
- fault status is showed by the red LED, inside the LME's lockout reset
buttonaccording to the "Error code table":
