2. Visually inspect that the mast is properly stowed and powered down. Ensure that the payload
will not bounce as the vehicle drives down the road. Once stowed, the Mast Stowed Safety
Interlock Contact signals it is safe to move the vehicle.
3. Store Remote Controls if used so they will not be damaged during transportation.
6.9.3
Emergency Stow with Power
If the mast cannot be stowed using the Auto Stow® feature or "Mast Down" button, the emer
-
gency stow button (S4) on the Base Board can be used to stow the mast if the following are both
true:
• Power is still applied to the system.
• The actuator is still functional.
Using the emergency stow button causes the actuator to lower the mast without regard to any
faults, switches, or system interlocks. It is totally up to the operator to ensure safe operation
during an emergency stow attempt. Also, the current limiting feature is not used so it is possible
to over-drive the actuator. Release the S4 button once the saddle is reached. Pressing the emer
-
gency stow button causes the system to generate an "ERR 1,20" error. Errors cause the mast to
automatically:
• Move the RCP to the home position (provided there are no electrical or mechanical issues
with the RCP).
• Exhaust all air from the mast, which lowers the mast to its nested position.
Once the mast has lowered to its nested position, pressing and holding S4 will drive the tilt actu
-
ator to stow the mast. The mast will continue to tilt and drive in the saddle until S4 is released. Do
not over-drive the actuator into the saddle.
To stow the mast using the emergency stow button:
1. Remove the left side cover (as viewed from the back of the mast).
2. Tap S4 on the Base Board. Do not hold down S4; just press, then immediately release S4
once. This will cause the controller to show an "ERR 1,20". The error will cause the RCP to
go to its home position and exhaust all air from the mast.
3. Wait until all air has exhausted from the mast. The mast should now be retracted and in the
90° position.
4. Ensure the RCP and lights are in the home position. If the RCP and lights are not in the home
position, manually adjust the pan or tilt of the RCP. Before adjusting the RCP or lights, make
sure that the lights have cooled completely. To adjust the pan, grasp the horizontal light shafts
and rotate to perpendicular to the base. To adjust the tilt, grasp the top and bottom of the
light, and slowly rotate the lights so they are face down.
5. Ensure there are no obstructions in the path of the mast.
