Mirror Cover Deploy/Retract sequence

ℹ️

REMEMBER

Before using the Deploy/Retract buttons power on the *Mirror Cover Locks* (MCLs), as these two commands will fail if the MCLs are not enabled.

  • Deploy sequence: this sequence is for extending all Mirror Covers (MCs). Sequence steps after pressing the Deploy button:

    • All the MCLs are moved to the unlock position

    • When the MCLs reach the unlocked position, two MCs are moved (Y+ and Y-)

    • When the MCs reach the extended position, two MCs are moved (X+ and X-)

    • When the MCs reach the extended position, the command is ended successfully

  • Retract sequence: this sequence is for retracting all Mirror Covers (MCs). Sequence steps after pressing the Retract button:

    • Two MCs are moved (X+ and X-)

    • When the MCs reach the retracted position, two MCs are moved (Y+ and Y-)

    • When the MCs reach the retracted position, all the MCLs are moved to the lock position

    • When the MCLs reach the retracted position, the command is ended successfully

For both commands, if during any of the steps of the sequence a fault occurs the motion will be stopped. Sending the command again, repressing the button, should work and complete the sequence successfully.

The limit switches indicating the Locked/Unlocked and Deployed/Retracted positions will be turned on when the command is complete, but these are very delicate and sometimes are unpressed when elevation is moved.

The sequence above refers just to the buttons actions, but before reaching there several conditions and steps must be executed:

  1. The mirror cover locks must be powered on, go to mirror cover locks window and power all the mirror cover locks ON, there is no need to move them, the deploy/retract command will do that.

  2. The elevation axis must be above 15 deg, the actual status of the axis, on/off/fault is irrelevant.

  3. Select ALL the mirror covers.

  4. Power ON the mirror covers.

  5. The status of all the mirror covers will be enable.

  6. Press the DEPLOY/RETRACT button, depending on the desired outcome. The sequence explained above will be executed in each case.

  7. Power OFF the mirror covers.

  8. Power OFF the mirror cover locks, using the mirror cover locks window, select ALL the mirror cover locks and press OFF.
