Dolev 4press - Troubleshooting & Diagnostics
The Test Tree - INTEGRATION

Ø Integration

Checks Signals between Boards + Gigs + External Devices.

Ø Signals

Checks Signals between Boards.

Ø Sweep On

Creates SWEEP ON pulses on STROBE5 and measure them in HOMC.

i) PLL tests Initialization.

1. Load CORRECTION LUT:
   Correction=8000H (no correction)
   no Start of Line Delay (0),
   no Expose Delay (4),
   no Lock Delay (3).
2. Load Div_N for 87.5 Mhz frequency (Resolution=100).
3. Start Run ALU
4. Measure SWEEP_ON frequency by HOMC to be 250 hz

Ø Expose Clock

Creates DATA EXPOSE pulses on STROBE5 and measure them in HOMC.

i) PLL tests Initialization.

1. Load CORRECTION LUT:
   Correction=8000H (no correction)
   no Start of Line Delay (0),
   no Expose Delay (4),
   no Lock Delay (3).
2. Load Div_N for 87.5 Mhz frequency (Resolution=100).
3. Start Run ALU
4. Measure DATA_EXPOSE frequency by HOMC to be 80 Mhz

• Note that there is blank region on the signal (without pulses), so the measuring is been done for 5 times until the expected result is been received. If after 5 times the result was not in the range, the last measuring is been displayed.

Ø Stop Spiral

Creates STOP_SPRL~ and END_SSP~ signals by CRI and checks the response to the STP_SPRRL~ signal on the STROBE5.

Ø Power Suppl.

Checks all plotter power supplies through the HOMC board:

+5v -5.2v +15v -15v +12v.

Ø Data Voltage

Checks the voltages from DATA unit through the HOMC board:

+12v -12v +5v.

Ø Panel

Checks Communication with panel

Ø Machine Exst

Checks if the mechanics and optics (machine) is connected to the Standard Controller

1) Check if both Carriage detectors are active -> illegal.

2) Check if both Cutter detectors are active -> illegal.

5) If 1-2 'true' then diagnostics conclusion - machine not exist.

*) MECHANICS + OPTICS tests will be not executed in the batch.

Ø Simulators

Checks Signals to Boards from jig (instead machine). Useful for production.

*) Excluded in short batch.

Ø OMC Detectrs

Checks the OMC ability to deal with detectors.

All machine detectors (include carriage HP EP) are tested.

Each detector is tested for:

1) shorting to GND.

2) shorting to VCC.

3) shorting to other detectors.

*) Requires HADAS detectors JIG (Guy Menchik).

*) Excluded in short batch.

Ø CRI Detectrs

Checks the CRI ability to deal with detectors.

Carriage Home Pos. and Carriage End Pos. detectors are tested.

*) Requires HADAS detectors JIG (Guy Menchik)

*) Excluded in short batch.

Ø Encoders

Checks the OMC ability to deal with encoders.

All machine encoders are tested exclude:

Spinner Index + Spinner Clock (to be updated by Guy)

Each encoder is tested for:

1) shorting to GND.

2) shorting to VCC.

3) shorting to other encoder or detector.

*) Requires HADAS detectors JIG (Guy Menchik)

*) Excluded in short batch.

Ø Analog Extrn

Checks the OMC ability to deal with extrnal analog voltages:

Dat +5v

Laser Value

Ø Amp Select

Checks the OMC ability to deal with optical signals:

AMP_SEL_1

AMP_SEL_2

Ø Com1<->Com2

CPU Board Com1 <-> Com2 test via 504G34023A cable.

*) Excluded in short batch.

Ø Com3<->Com4

OMC Board Com3 <-> Com4 test via 504D39421 cable.

*) Excluded in short batch.
