Figure 5-8 Example Vehicle Safety Interconnect Circuit
The contact output is set at the factory to be OPEN when the mast is active (not stowed) by set -
ting the S2-1 dip switch to the OFF (OPEN) position. To change the contact output to be
CLOSED when the mast is active, set the S2-1 dip switch to the ON (CLOSED) position. Mast
power needs to be cycled for this change to take effect.
5.6.5 Wiring Optional Enable Circuit
Some safety standards requires preventing operation of the mast unless other conditions are first
met. An example might be having the parking brake set. This can be accomplished by inserting
an isolated contact in series with the stop circuit of the "E-Stop" button. Inserting these contacts
in line with the wire connected to pin J4-7 on the base circuit board breaks continuity and will
inhibit operation of the mast and prevent operation until the parking brake is set. After use, and
properly stowing the mast, when the parking brake is released, the mast is again prohibited from
energizing until the parking brake is set.
Note: Using this parking brake feature is the same as pushing the E-stop button. Power to the
control is opened, the mast immediately exhausts air, and the mast comes down without regard
to the proper RCP alignment (stowing to the home position). The parking brake should not be
released until the mast is safely (and automatically) stowed by the controls.
5.6.6 Secure Wiring and Attach Cover
6. Secure all loose wires with wire ties.
7. Attach the 0.709 inch (18 mm) inside diameter ferrite (shipped loose with the mast) around
the Control/DC cable as it enters the base. This ferrite provides EMI (electromagnetic inter -
ference) filtering.
8. Once all wiring connections are complete, replace the base cover and tighten the three
mounting screws.
