Auto Return To Dock (ARTD)
EH levelers can be equipped with optional Auto
Return To Dock (ARTD) if leveler is not interlocked
with a transport vehicle restraint.
The ARTD uses a proximity switch (
B
) located under
the platform and a piece of angled steel called the
target (
E
) that is attached to the lip hinge tube (
F
).
See Figure 28.
The proximity switch provides a six-second delay
after the platform has lowered to the full below-dock
position, after which the platform will return to the
cross-traffic position. The switch also contains an
indicator light (
H
) that can be used for diagnosing
and adjusting the switch.
Note:
Some proximity switches have an indicator light
at the back of the housing and some have the light at
the side of the housing.
