Project: DEIMOS
Stage: Entrance Hatch
ID #: KDWN-001A
Engineer: J. Osborne

Mechanical Description of Stage: An air cylinder opens a hinged aluminun cover in front of the entrance window.  There are covers for side "A" and side "B".

Electronic Description of Stage: Pneumatic solenoid that is controlled by a Galil/Opt0-22 I/O bit.

Required setting accuracy:

1. Speed, temperature, accuracies, electrical power, pressurized air, lubricant, coolant, N2 purge, ...
2. Primary (inner) and secondary (outer) limits. These can be magnetic, optical, or physical contact

1. Uphill defined as motor (or driven end of shaft) in lowest position

1. "Coarse" if from optical interupter, "Fine" if from an encoder index pulse. Home is defined as zero counts.
2. Primary limits signal the controller to stop motion. Secondary limits cut motor power and require intervention to move out of them.

Sign conventions are such that a positive motion of the motor turns the motor in a CW direction as viewed from the drive shaft looking back into the motor, and will drive the stage towards the forward limit.
