Cart Operation Plan

• People authorized to perform the following procedures.

Eric Scott

• Moving the cart from one position to another (Alcove / Platform) requires two people.

1. Carriage must be moved to the marked transport position and secured in place with at least 2 screw-in stops and the outrigger wheel must be moved to its marked transport position and secured in place.
2. Outrigger caster locks need to be released so that the wheels are free to swivel.
3. The cart foot lock (found under the left side of the cart) must be released.
4. The cart stabilization legs need to be screwed up so they clear the floor by about 1/2".
5. Two people are necessary to push the cart and watch for obstructions while moving it and align it in its new position.
6. Location specific instructions must be followed (found below).

• Cart in the platform position

1. Must have at least 2 people on the platform to move the carriage on top of the cart.
2. Ensure that the cart is secured:
   1. The stabilization legs need to be extended and rotated 1/4 turn with a wrench after hand tightening into the floor.
   2. The foot lock (found under the left side of the cart) must be set.
   3. The large wheels need to have the wooden wedges placed on either side of them.
3. The cart motion system will remain in the power off condition.
4. When moving the carriage in relation to the cart release the screw-in stops and slide the carriage to the next position then re-secure with at least one stop. To reach the ends of the module it may be necessary to reposition the cart following the above procedure.
5. Ensure the outrigger is in its "normal" position (second bolt location on the right).

• Cart in alcove position

1. Ensure that the cart is secured:
   1. Bolted the cart to the alignment angles on the floor.
   2. The stabilization legs need to be extended and rotated 1/4 turn with a wrench after hand tightening into the floor.
   3. The foot lock (found under the left side of the cart) must be set.
   4. The large wheels need to have the wooden wedges placed on either side of them.
2. Turn on motion system:
   1. Make sure cart computer is on (Blue light on left of cart).
   2. Turn on CAMAC Crate.
   3. Turn on motor AC interlock (Button on right side, when engaged a light below the button comes on and motor hums.)
3. Slide carriage (This portion must be repeated for each new carriage position):
   1. Loosen Locks on carriage.
   2. Loosen locks on outrigger casters.
   3. Pull or push carriage to desired location.
   4. Tighten at least 2 locks on the carriage.
   5. Use a small jack to just lift casters off the floor so that they can be spun 90 degrees. Leave the locks loose.
   6. Engage drive system and rotate the carriage in the direction you set the casters.
   7. Lock the casters at the appropriate angle.
4. Check for clearance through the entire angular travel before turning system over to remote control.
   1. Either move the system with the controls on the front of the SMC24B motor control module or log into the computer using the screen and keyboard plugged into the cart computer.
   2. Ensure that the stops are set to prevent any collision.

• Operating cart under remote control

1. Ensure that cameras are working and a clear view of the cart is possible.
2. Log into the cart computer, using the software tell it the angle you want to move to and watch the encoder value and camera views for anything out of the ordinary. If a problem arises: press Ctrl-C this halts the drive system.
