5. Lower the mast to the stowed position by holding the "Mast Down" button until the mast is
stowed. Immediately release the "Mast Down" button when the mast is stowed. If you drive
the mast too far into the saddle, you may receive a "1,04" error (excessive amp draw during
actuator decline). Do not use the Auto Stow® feature to stow the mast.
6. Check that the mast is properly stowed. This will be indicated by the diagnostic LEDs on the
Base Board. As the mast comes down D11 and D13 will be green, and D7 will be yellow.
Once stowed, D7 will also turn green (see Figure 7-1).
7. Raise the mast to gain access to the Mast Stowed Switch.
8. Secure the switch in position by tightening the lock nuts.
9. Raise and lower the mast several times, checking that the mast stows each time, and adjust
the switch if necessary. There should be no mechanical play between the RCP and the sad -
dle when properly stowed.
10. Replace the base covers.
7.5.4 Adjusting the Mast Magnetic Down Switch
The Mast Magnetic Down Switch tells the control system the mast is fully retracted and allows
the mast to tilt back to the stowed position. The Magnetic Down Switch is band-clamped to the
base tube. This switch senses a magnet in the top tube when the mast is at 90°, or stowed, but
not extended. The magnet is located in a recess at the bottom of the top tube and is not visible
from outside the tube. If the Magnetic Down Switch is mis-adjusted, the mast may give an error
code upon power up, or may not stow from 90°. When adjusting the Magnetic Down Switch,
ensure that the mast is at 90° or stowed with all collars stacked and no gap between them.
Before delivery of a new system, all switches are properly set and tested and normally no switch
adjustment is necessary. However, if an adjustment is required, adjust as follows:
1. Deploy the mast to some point between 0° and 90°.
2. Loosen the band-clamp that holds the Magnetic Down Switch and lower the clamp to the bot -
tom of the mast.
3. Remove the left base cover to expose the base PC Board diagnostic LEDs (see Figure 7-1).
4. Ensure the mast is fully nested (no gaps between collars). While observing the Base Board
diagnostic "Mast Down" LED, slowly move the band-clamp up until the "Mast Down" LED
turns green.
5. To test:
a. Initiate the mast.
b. Press the "Mast Down" button on the controller until the mast stows. If the mast does not
stow, repeat steps one and two several more times or until the mast stows.
