6.8.3 Emergency Stow with Power
If the mast cannot be stowed using the Auto Stow® feature or "Mast Down" button, the
emergency 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.
• Applicable system components are still functional.
Using the emergency stow button causes the mast to lower 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. Release the S4 button once the saddle is reached. Pressing the
emergency 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.
To stow the mast using the emergency stow button:
1. Open the control box lid to expose the base board.
2. Tap S4 on the base board. Do not hold down S4; just press, then immediately release S4
once. This causes the controller to show an "ERR 1,20". The error causes the RCP to go to
its home position and exhausts all air from the mast.
3. Wait until all air has exhausted from the mast. The mast should now be retracted.
4. Visually check that the mast is properly stowed. Ensure that the lights do not bounce as the
vehicle drives on the road.
5. Close the lid on the control box.
6.8.4 Emergency Stow without Power
Since the pneumatic system operates with the mast pressure chamber normally open without
power, it is likely the mast will retract automatically without power. If it does not retract, turn the
drain cock at the base of the mast to exhaust air and lower the mast.
Note: This method will leave the RCP and lights in whatever orientation they were left in. Ensure
they do not contact vehicle structures.
