Inclinometer
Safety Devices
1-
When the motorized unit is moving, if the inclinometer detects a slope of ± 2 degrees,
a signal is automatically sent to the control panel and the ± 2-degree alert is displayed.
2- On an F300 unit model
,
during ascent at second (high) speed
, the screen on the
control panel of the motorized unit that is at the highest level in the confi guration will
display an alert (
>2DEG NEG
) and automatically shift the unit to fi rst (low) speed while
the lowest side (
>2DEG POS
displayed on the screen of that unit) will continue to rise
at second (high) speed until the structure is brought back to level. If the structure is
rising at fi rst (low) speed, the highest motorized unit will stop completely until the
structure is back to level.
During ascent
, if the highest motorized unit is a
model F200
, the screen on the control
panel will display an alert and automatically
stop
the unit.
The unit will resume ascent
only when the structure is brought back to level.
3- On an F300 unit model
,
during descent at second (high) speed
, the screen on
the control panel of the motorized unit that is at the lowest level in the confi guration
will display an alert (
>2DEG POS
) and automatically shift the unit to fi rst (low) speed
while the highest side (
>2DEG NEG
displayed on the screen of that unit) will continue to
descend at second (high) speed until the structure is brought back to level. If the structure
is descending at fi rst (low) speed, the lowest motorized unit in the confi guration will stop
completely until the structure is back to level.
During descent
, if the lowest motorized unit is a
model F200
, the screen on the control
panel will display an alert and automatically
stop
the unit.
The unit will resume descent
only when the structure is brought back to level.
Detection of a ± 2-degree slope
1-
When the motorized unit is moving, if the inclinometer detects a slope of ± 5 degrees,
a signal is automatically sent to the control panel and the ± 5-degree alert is displayed.
2- During ascent
, the motorized unit that is at the highest level in the confi guration (
>5DEG NEG
displayed on the screen of the control panel) will automatically
stop
and
resume ascent
only when the structure is brought back to level.
3- During descent
, the motorized unit that is at the lowest level in the confi guration
(
>5DEG POS
displayed on the screen of the control panel) will automatically
stop
and
resume descent
only when the structure is brought back to level.
4-
If the inclinometer or its connection is defective, the motorized unit will not operate.
In that case, call a qualifi ed person. For the defi nition of a qualifi ed person, refer to
p. 7 of the
Performance and Safety Rules
section.
Detection of a ± 5-degree slope
1-
Make sure the bearing bridge structure is level.
2-
Activate the display screen of the control panel and select the
inputs/outputs section (
F3
) on the main menu screen.
3-
Navigate to the page where the inclinometer level readings are
displayed (fi g. 2.7).
4-
Loosen the adjustment bolt on the inclinometer sensor located
on the left-hand side of the bearing bridge (“L” in fi g. 2.8).
Adjustment of the 0° level position
5-
Move the sensor until a 0.00 reading is displayed in the
inclinometer input fi eld on the screen. Tighten the bolt to secure
the sensor in place.
6-
Repeat steps 2 through 5 to adjust the inclinometer sensor located at the right-hand
side of the bearing bridge (“R” in fi g. 2.8).
