Faults - Probable causes - Solutions
The LFL1.333RL control box is equipped with a lockout indicator
(Fig. 38) that turns during the start-up programme, and is visible
from the small lockout window.
When the burner does not start or stops, due to a failure, the sym-
bol that appears on the indicator indicates the type of interruption.
The positions of the lockout indicator are shown in Fig. 39.
Fuse replacement
The fuse 2)(Fig. 40) is in the rear part of the control box. A spare
fuse 1) is also available: it can be extracted after breaking the
panel tab A) that houses it. In the event that fuse 2) has been
tripped, replace it as shown in Fig. 40.
Find a list of faults, causes and possible solutions for a set of fail-
ures that may occur and result in irregular burner operation or no
functioning at all.
If a burner malfunction is detected, first of all:
–
check that the electrical wiring is adequately connected;
–
check whether fuel is delivered;
–
check that every adjustment parameter is adequately set.
