5.10.6 Wiring Optional Enable Circuit
Some safety standards require 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, which
inhibits operation of the mast and prevents 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.
5.10.7 Power-up and Magnetic Switch Adjustment
Note: When applying power to the mast for the first time, it is possible the light fixtures will rotate
(tilt) to the stowed position. Stay clear from the light fixtures during power-up.
Once all wiring connections have been made, apply DC power to the mast control system. Press
the start button to power up the mast system.
With the mast fully nested (no gaps between any of the collars and the RCP is touching the
saddle brackets) and the lower magnetic switch is toward the bottom of the mast base tube,
loosen and slowly move the lower magnetic switch up on the mast. Continue to raise the bracket
location while observing the base board LED labeled “Mast Down”. When the LED turns green,
you have reached the location of the magnet inside the mast. Move the magnetic switch up 6 mm
(1/4 inch) from this activation point (this accounts for temperature variations in magnetic field and
magnet physical position) and tighten the band clamp. Be sure the magnetic switch bracket is still
oriented properly and the LED light is still green after the band is tightened.
The upper magnetic switch does not need to be adjusted from the initial position just below the
mast base tube collar. If desired, the upper switch can be lowered to cause the RCP to become
active at a lower height. The installer must ensure that the RCP is free to pan and rotate 360°
without hitting any obstructions on the vehicle at any lowered height.
5.10.8 Secure Wiring and Attach Control Box Lid.
1. Secure all loose wires with wire ties.
2. Tighten all cable grips. If multiple cables are routed through the same cable grip on the
control box, apply sealant to help keep water from entering the control box.
3. Close the control box lid and secure the lid screws to complete the installation.
