  5. Dual Actuator

  6. Actuator cylinder

  7. Hard Point Actuator

  8. Problems and Failures Enclosures • Shutter structure Clay • Enclosure jib cranes • UPS batteries • Louver seals • Wind Screen & Moon Roof drives • Rotating interface seal

  9. Work in Progress • Enclosures • Louver seals • Rotating interface seals • Windscreen & Moon roof drives • Rotating seal (Baade) • Louver position encoders limits • Power line slip ring modems

  10. Work In Progress • Software • M3 Tip-Tilt automation • Code normalization, ini files • Translate Fortran to C++ (enclosure) • Windscreen & Moon roof automation • EDS query tools • PWM Amps, Rotator guiding, servos • M1 thermo control servo

  11. Work completed • Iodine cell actuator (Clay), ADC (MIKE) actuator and guider (#6) installed and tested • New rotating enclosure seal (Clay) • New jib crane limit switches (both enclosures) • New flat field lamp supplies and software • Aluminized M1 and M3 mirrors Baade • Washed M1 and M3 mirrors Clay • Clay shutter drive U-joint replacement • New Az & El drive bearings Clay

  12. Problem reporting • Gnats problem tracking software installed locally. This is now our only problem tracking system • Telescope reports for night time problems and comments • Forums are used to transfer information and changes

  13. Safety • Safety review by ACHS • Fire detection system was inspected and serviced • Fire extinguishers serviced • New policies on equipment operations, licenses required for all equipment, classes, training and licensing in progress • Road maintenance in progress • Poly-clinic inventory & supplies.
