Getting Started

3.1 Power Up Procedure

HBAR (ALFA) power up procedure after installation at MPIA in Heidelberg.

Notes:

1. Everything is OFF (except the Sun work station).

2. UFORIA transmitters must be powered before the receivers.
This is done because the UFORIA receivers have to phase-lock to the transmit carrier.

2.1 If the VME-UFORIA error light comes ON due to someone turning OFF and back ON the LL camera or disconnecting a fiber cable, etc.

2.2 Try clearing the error from the HBAR user interface with the re-init button (The VME must be ON).
If this does not work you need to do the powerup procedure correctly.

2.3 If the UFORIA-R (for the DM) error light comes ON due to someone turning OFF and back ON the VME rack or disconnecting the Fiber cable.

2.4 You have to do the powerup procedure. You can try cycling power on the UFORIA-R (for the DM) if only the fiber link has been disconnected and reconnected BUT ONLY after properly powering down the DM. Note that clearing the DM will not be possible for this situation.

3. The Stages (Stage Driver chassis MUST always be initialized after powerup to establish valid position numbers.

3.1 The stages may be left ON even if the VME chassis is OFF. This will retain the position numbers. If a stage is moved by hand, then you must reinitialize that stage.

3.2 Stages with encoders are generally set to closed loop operation and CAN NOT be turned by hand since the closed loop feedback will move the stage back to the original position Damage can result if you force the stage.

3.3 There are several (DEVELOPMENT) Tcl scripts written to develop the stage control. Some are:


init_stage.tcl, show_param.tcl and save_param.tcl. These are located in the directory ~carlos.

THESE ARE PRE-RELEASE SCRIPTS and are not under revision control.

To use (Don't run the real hbar system while doing this)

These scripts are only for stage control development.

THE SCRIPTS ARE HEAVILY COMMENTED.

Please read the code before using.

It is very IMPORTANT to understand what you are doing to prevent

damage to the drivers or the stages.

EXAMPLE:

cd ~ carlos

hbar

source source.tcl (This loads up my scripts)

init_stage stage_name 0 0 0 0 will init the named stage

show_param stage_name will show the parameters

save_param stage_name will store parameters in the IMS module.

init_names is where the stage_names are defined for these tools

(not for the real hbar software). this script is run by

source.tcl

The stage_name.parameters files are essential and commented.

This is were all the important parameters are plugged in.

3.4 RELEASED versions of the stage scripts and parameter files used by the HBAR system are in:

HBAR-stage-tcl and HBAR-config respectively.

These are under revision control.

4. Assumes the Sun work station is already booted and installed.

5. This procedure includes AOA Wavefront Sensor only.

Startup Procedure:

1. Turn ON fan to Lincoln Lab camera and other
(MPIA installed) cooling as required.

2. Turn ON Lincoln Lab Camera power supply. (Also turns ON UFORIA-T).

3. Turn ON AOA Stage Driver Chassis.

4. Turn ON AOA VME chassis (This includes power to VME-UFORIA).

4.1 VME starts to boot from Sun workstation.

4.2 Wait for lower red light on the VME-UFORIA to go out.

5. Turn ON UFORIA-R (Used with DM).

6. Turn ON DM (see bellow).

DM Procedure:

DM Notes:

1. The D/A converters in the Xinetics rack must be initialized to null before power-up or power-down. This value is Hex 8000.
The HBAR user interface has a button for issuing this command. There are ao.dm.xxx commands available from

2. The DM high voltage current limit must be set to allow enough current for normal operation. 2.5 turns clockwise is the default.

3. The DM master breaker is in the back of the rack.

DM turn ON:

1. Make sure VME-rack has been booted and the UFORIA-R is powered.

2. Check that the master breaker in the back is ON. 230V AC is present.

2. Turn ON the top-front circuit breaker. The boot light will come ON for about 1/2 second. The other light may not always have the same pattern.

3. Check that the voltage knobs are fully counter clockwise

4. Check that the current knobs are set as noted above and have not been disturbed.

5. Turn ON both High voltage power supplies.

6. SIMULTANEOUSLY turn the voltage knobs until both voltages read 40 volts.
Keep the voltages within +/- 5 volts.

7. Raise the 80 Volt power supply voltage (bottom) until 70 volts are reached.

DM turn OFF:

1. Send clear DM command from the HBAR user interface. There are also ao.dm.xxx commands available from the command line.

Turn off rest of system:

1. Reverse startup procedure outlined above.

2. The Stage motor drivers can be left On to preserve the stage positions.
