Autofib 2 Quality Assurance
Mechanical
Electronic
Calibration Checks
The Day Before The Change
Mechanical
-
Check Autofib visually for any problems. Particularly check the Gripper
mechanism.
-
DO NOT USE SPRAY LUBRICANTS OR COMPRESSED AIR TO CLEAN AND LUBRICATE AUTOFIB!
-
Lubricate Autofib using a cloth impregnated with oil. Be careful not to
get any lubricant on the prisms!
Electronic
-
Set Autofib up in the test focal station in the WHT. Do not fit the fibre
module yet!
-
Visually inspect Autofib internally for broken wires, loose connections,
etc.
-
Power up Autofib.
-
Place a metallic object on the large/small fibre sensor, depending on which
module is in use.
-
Initialise Autofib's control system.
-
Wake the robot. The robot should move to the centre.
-
Sleep the robot. The robot should move to the far corner.
-
Remove the metallic object from the large fibre sensor.
-
Fit the fibre module.
-
Back illuminate all the fibres using the back illumination test rig.
-
Wake the robot.
-
Perform a <loadmodule> command in engineering mode to check that Autofib
knows where all the fibres are.
-
If <loadmodule> fails, then manually place all the fibres into the load
ring and use <ringallfibres> to update the positions. Afterwards, <loadmodule>
will update the fibre positions.
-
Perform a field set up.
-
Park the fibres.
-
Sleep the robot.
-
Shut the control system down.
Calibration Checks
-
Check the alignment of the camera to the robot as per Autofib 2 technical
note 2 gripper unit mechanical and optical alignment.
The Day Before
The Change
-
Disassemble Autofib and prepare for Autofib to be lifted up to the dome.
-
Put Autofib's VME crate, servo amplifier crate, VT220 terminal, frame grabber
monitor and engineering mimic display in GHRIL.
-
DO NOT POWER ON.
-
Connect Autofib's control system in GHRIL together.
-
Power on ONLY Autofib's VME crate.
-
Check that Autofib is on the network. Remember that Autofib has two network
connections!
-
Power VME crate off.
