Check correct operation of the:
a) motor (thermal protection N7);
b) top limit switch (S5 and S5’).

The hood is open but the bottom limit switch
(FC_DW) has cut in.
Appears with hood fully open, if:
- the limit switch (S5) returns to the rest posi-
tion;
- the bottom limit switch (S3) cuts in;
- S3’’ cuts in
.

Appears if with hood fully open the "door closed"
microswitch cuts in.
Appears if with hood fully open the "door

During lowering, the top limit switch (FC_UP) has
not returned to the rest position.
The limit switch must return to the rest position
within a time given by parameter
:
a) check that the motor works;
b) (Polarity/motor rotation direction inverted?!)..

During the initial lowering phase the top limit
switch (S5) must return to the rest position
within a time given by the parameter
 oth-
erwise the alarm
 appears.
- S5 could be stuck.
- S3’ could be disconnected.
On installation, this alarm can occur due to
incorrect sequence of the phases: invert the two
phases on the power supply terminal board.
