System Functional Overview Executive Processor Block After the user requests an operation (with a front panel control for instance), the Executive Processor (EXP) directs the CSA 803C to perform this operaĆ tion. Another primary function of the EXP is to execute diagnostic SelfĆTests on the instrument when poweringĆon or at the user's request. To control operations, the EXP controls and monitors the other circuit boards sharing the executive system bus.
System Functional Overview Front Panel Controls User control of the CSA 803C is primarily through the following three front panel controls: the frontĆpanel majorĆmenu buttons the touch panel the multifunction knobs The major menu buttons are the top level menu selections for the instruĆ ment. Touching an icon, menu item, or waveform selects that particular icon, menu item, or waveform, respectively. The multifunction knobs control the function of the particular item that is selected.

Performance Tests PowerĆOn Diagnostics This procedure should be performed within the ambient temperature range of +18 C to +28 C (64 F to 82 F) when a performance check at peak operating conditions is required. Setup to Invoke PowerĆOn Diagnostics CSA 803C Sampling Head (not installed yet) Procedure to Invoke PowerĆOn Diagnostics CAUTION Applying a voltage outside the range printed on the sampling head can result in damage. Static electricity is also a hazard.
Performance Tests ăStep 5:ăSet the rear panel PRINCIPAL POWER SWITCH to ON and then set the CSA 803C's front panel ON/STANDBY switch to ON. When the CSA 803C is first installed, the rear panel PRINCIPAL POWER SWITCH should be set to and left in the ON position. From then on, use the front panel ON/STANDBY switch to perform all subsequent power switching. ăStep 6:ăMonitor the following diagnostic run functions, and note the range of possible results.

Corrective Maintenance Fan Motor Removal/ Replacement See Figure 6Ć2 for connector and screw locations. Remove and replace the fan motor as follows: ăStep 1:ăUsing a pencil or tape, mark the top of the fan motor housing for later use in determining the positioning of the motor. Remove the four screws securing the housing to the rear of the instrument mainframe. Hold the housing as you remove the last screws. ăStep 2:ăSeparate the grill and the housing from the motor.
Corrective Maintenance Cathode Ray Tube (CRT) Removal/ Replacement WARNING The cathode ray tube (CRT) may retain a dangerous electrical (16 kV) charge. To prevent electric shock, fully discharge the anode before removing the CRT. Short the anode lead from the CRT to the chassis. Wait approximately ten minutes and again firmly short the anode lead to the chassis. Then, remove the CRT. If the CRT breaks, the glass fragments scatter at a high velocity (implosion). Use extreme care when handling the CRT.
Set the A9 Touch Panel Assembly aside. To avoid stressing the ribbon cable that is still connected to the A9 Touch Panel Assembly, and to keep the assembly from cluttering your work space, place the A9 Touch Panel Assembly on top of the sampling head compartments. Do not damage the A9 Touch Panel Assembly when placing it on top of the sampling head plugĆin compartments. Carefully set the instrument on its left side.

This section provides the information necessary to troubleshoot a faulty CSA 803A to the field replaceable unit (FRU) level. In most cases a FRU is a circuit board. The primary means for troubleshooting is to use the error index code output from the Kernel diagnostics and crossĆreference it to the suspect circuit boards in the following tables, or to use the builtĆin FRU help function available in Extended Diagnostics.
Kernel diagnostics are executed each time the front panel ON/STANDBY switch is set to ON. The CSA 803C performs powerĆon diagnostics on its microprocessor subsystems and SelfĆTest diagnostics on all of its major circuits. When Kernel diagnostics begin, the messages and are displayed.

Diagnostic Troubleshooting Diagnostic Menus The upper portion of the display screen is used to display diagnostic menus. Menus are comprised of menu items and menu fields. Menu items are rows of items that can be selected, while menu fields are columns of status inĆ formation. There are four tiers of menus which may appear in the menu area (only one is present at any given time): the Subsystem, Block, Area and Routine menus. Upon entry into any menu, there is always one menu item that is selected.
Diagnostic Troubleshooting " (blank) This status indicates that the test requires action from the user (such as the front panel verification tests), or that the test is for stimulus only (such as the manual calibration tests). This status does not provide failure status. To execute this test, select it individually.

Diagnostic Troubleshooting Battery Testing The CSA 803C holds four lithium batteries to provide power when the instruĆ ment is turned off. The following discussions provide criteria for determining if a battery has exceeded its lifetime, and is thus causing incorrect instruĆ ment operation. (A battery's lifetime will typically exceed five years.

Other Troubleshooting Fuse Testing The A14 I/O board has four fuses (see Figure 6Ć37). F200 supplies +5 V to the A12 Rear Panel board. F800 supplies +5 V to the A10 Front Panel ConĆ trol board and the A9 Touch Panel board. F600 supplies +15 V to the A14 I/O board, card cage, A10 Front Panel Control board, A9 Touch Panel board, A11 Front Panel Button board, and A12 Rear Panel board (reduced to +12 V).
$ " " % # $ See Figures 6Ć2 and 6Ć37 for the location of the line fuse and the A14 I/O board fuses, respectively. When a fuse must be replaced, unsolder the fuse from the board. Be careful not to damage the solder pads on the board. (It may be helpful to straighten the fuse leads on the rear of the board before removing the leads from their holes in the circuit board.) Refer to the Parts List section for the correct value and part number of each fuse.
