Comments:
The Top Landing Gate is closed
by spring loaded hinges which are
field adjustable to increase or
decrease closing force. If the Top
Landing Gate is not fully closed
the Top Landing Gate monitor
switch will stop the VPL operation
and the Top Landing Gate
indicator light will illuminate.
Comments:
This situation indicates the upper
limit is set a considerable distance
above its correct position. In order
to correct this adjustment the Top Landing Gate Bypass Jumper will
need to be temporarily plugged
into the Top Landing Gate
connector so the Top Landing
Gate latch will not stop the travel
of VPL platform during adjustment.
If the jumper is not available, the
roller on the Top Landing Gate
latch can be removed temporarily
during adjustment so the latch is
not actuated.
Comments:
The EMERGENCY STOP
BUTTON disconnects power to
the motor and the VPL will not
operate when the button pushed
in.
WARNING: Pressing the
Emergency Stop Button/Button
DOES NOT disconnect power to
the battery charger. The only way
to disconnect power to the battery
charger is to unplug the VPL from
the AC outlet.
Solution:
Check for free swing operation of
the Top Landing Gate. Also check
that the spring tension on the
hinges is sufficient to fully close Top
Landing Gate. Adjust hinge spring
tension as needed. Check that the
Top Landing Gate latching
mechanism is in the correct position
so that the latch can fully close
around the catch rod. Refer to the
VPL Installation Manual Top
Landing Gate Placement and
Installation section for adjusting the
height of the latching mechanism
and Top Landing Gate.
Solution:
Unplug the Top Landing Gate from
the VPL and plug the Top Landing
Gate Bypass Jumper back into the
plug. Adjust the upper limit trigger
ramp as described in the installation
manual.
WARNING: This type of adjustment
must be done by a qualified
technician. Consult your dealer for
additional information.
Solution:
Pull the EMERGENCY STOP
BUTTON out to deactivate.
WARNING: Pressing the
Emergency Stop Button/Button
DOES NOT disconnect power to
the battery charger. The only way to
disconnect power to the battery
charger is to unplug the VPL from
the AC outlet.
