(Polarity/motor rotation direction inverted?!).
Appears if the bottom limit switch (S3) cuts in during
lifting.
On installation this alarm can occur due to incorrect
sequence of the phases: invert the two phases on the
power supply terminal board.
AL_5
TIMEOUT-
The time taken for hood lifting was
more than the time fixed by parameter
t_2
:
a) check that the motor works.
TIMEOUT-
The time taken for lifting was more than the
time fixed by parameter
t 2
.
Check correct operation of the:
a) motor (thermal protection N7);
b) top limit switch (S5 and S5’).
AL_6
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 position;
- the bottom limit switch (S3) cuts in;
- S3’’ cuts in.
AL_7
Appears if with hood fully open the "door
closed" microswitch cuts in.
Appears if with hood fully open the "door closed"
microswitch cuts in.
- S5 could be disconnected.
AL_8
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
t_6
:
a) check that the motor works;
b) (Polarity/motor rotation direction inverted?!).
b 3
During the initial lowering phase the top limit switch
(S5) must return to the rest position within a time given
by the parameter
t_6
otherwise the alarm
b 3
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.
AL_9
-
Appears if the bottom limit switch S3 cuts in before S3"
during lowering.
AL_10
Appears if the top limit switch (FC_UP) cuts in
during lowering.
(Polarity/motor rotation direction inverted?!).
b 3
Appears if the top limit switch (S5) cuts in during
lowering.
On installation, this alarm can occur due to incorrect
sequence of the phases: invert the two phases on the
power supply terminal board.
AL_11
TIMEOUT-
The time taken for hood closing
was more than the time fixed by parameter
t_2
:
a) check that the motor works.
TIMEOUT-
The time taken for lowering was more than
the time fixed by parameter
t_2
.
- S3’ could be disconnected.
AL_12
-
Appears during hood lowering if, after S3’’ cuts in, the
bottom limit switch S3 does not cut in within the time
fixed by parameter
t 3
.
AL_13
-
The two hand safety contacts K and K'
must be both closed or both open. If this
does not occur the alarm appears.
- One of the two relays (K or K’) could be stuck or
