Adjust Auto Return To Dock (ARTD)
1. Raise platform fully and engage the maintenance
prop in the service position. Allow platform to rest on
the prop so the lip will fully fold until it contacts the lip
stops.
2. Turn OFF all electrical power to the leveler and
lock out/tag out the electrical power supply.
3. Loosen lock nuts (
D
). Adjust proximity switch (
E
)
to obtain distance (
A
). Tighten lock nuts.
4. Bend target (
B
) as needed to obtain distance (
C
).
Recheck distance (
A
) and readjust if necessary.
Note:
At least two people may be required to
manually move the lip.
5. After adjusting proximity switch and target, slowly
move the lip up by hand while observing the target
and proximity switch. The target MUST NOT contact
the switch, otherwise, damage to switch will occur.
Readjust switch and/or target if necessary, then
recheck for interference.
6. Remove lock out/tag out and turn ON electrical
power to the leveler.
7. Disengage the maintenance prop.
8. Turn the ARTD switch (on control panel) to the
ON position.
9. Raise the platform until the lip is fully extended,
then allow the platform to drift to the below-dock
position. After approximately 6 seconds, the platform
should return to the cross-traffic position.
10. Adjust the proximity switch and target as
necessary. Make small adjustments, then operate
the dock leveler to check results. Do this until
satisfied with the ARTD operation.
Note:
Use the illustrations on page 40 to assist in
fine tuning and/or diagnosing the ARTD operation.
A— 1/4 in. (6.4 mm)
Approximate
B— Target
C— 1 in. (25.4 mm)
Approximate
D— Lock Nuts
E— Proximity Switch
Note:
Distances (
A
and
C
) in Figure 29 are typical
factory settings. Use these dimensions only as a
starting point when adjusting the proximity switch and
target, especially if switch and/or target have been
replaced.
When dimensions (
A
and
C
) are obtained, the
proximity switch and target may need finer
adjustments to get the ARTD to operate as desired.
Whenever proximity switch and target are adjusted,
check for interference between target and switch
before operating the leveler. Damage to switch will
occur if the target contacts the switch.
The maximum torque for proximity switch lock nuts
is 27 N
•
m (29 lb-ft). Damage to switch will occur if
maximum torque is exceeded.
