TO ENSURE SAFETY

This Service Manual has been compiled for the purpose of facilitating repair and maintenance of the WR1000 Series Thermal Arraycorders by Graphtec service personnel and other persons who have undergone equivalent technical training.

Maintenance or repair by unauthorized service personnel is to be strictly avoided. Because the WR1000 contains numerous internal components with a high electric potential, such work by unauthorized service personnel could cause human injury or serious damage to the recorder.

2. UPGRADING THE FIRMWARE

The version of your WR1000’s firmware can be upgraded by rewriting the flash ROM on the pertinent circuit boards using one of two methods. You can upgrade the firmware by loading the update program from either floppy disks or from a personal computer via the RS-232C interface.

2.1 Upgrading from Floppy Disks

(1) Turn off the WR1000. (2) Insert the floppy disk containing the upgrade program into the WR1000’s floppy disk drive. (3) Turn on the WR1000 to automatically execute the upgrade program. (4) Wait until the display shown below appears.

Mxxxxxxx.W10: Files for upgrading the main CPU Sxxxxxxx.W10: File for upgrading the sub CPU Pxxxxxxx.W10: Print pattern file

Fig. 2-1-1

(5) Use the and keys to select the file for the upgrade operation you wish to perform. (6) To begin rewriting the target flash ROM, press the

ENTER

key on the Conditions panel.

(7) The following message appears to indicate that the upgrade operation has terminated normally.

Fig. 2-1-2

(8) Turn off the WR1000 and then remove the floppy disk.

2. UPGRADING THE FIRMWARE

NOTE

• To conduct multiple upgrade operations, repeat Steps (1) through (8) for each of the upgrade files you wish to execute.

• After you have executed an update program, the Display mode will automatically be switched to English (US) and other settings will also be changed.

CAUTION

The program for upgrading the main CPU is split into the two files listed below which are stored in two floppy disks:

MxxxA001.W10

MxxxA002.W10 When upgrading the main CPU, therefore, first insert the first floppy disk into the floppy disk drive, turn on the WR1000, press the

ENTER

key after the update program is loaded, and then wait until the prompt

message below appears.

Fig. 2-1-3. Prompt for inserting the second disk

After the above prompt appears, replace the first floppy disk in the floppy disk drive with the second disk, then press the

ENTER

key. When the message appears to indicate that the upgrade program has been normally terminated, turn off the WR1000 and remove the second disk. Note that the upgrade file for the sub CPU and the print pattern file are contained in the second floppy disk.

3. DISASSEMBL Y AND REASSEMBLY

3.1 Notes on Disassembly and Reassembly

• During disassembly, disconnect the cables from the specified connectors as necessary.

• During reassembly , double-check to ensure that the proper cables have been correctly re-connected to the

pertinent connectors.

• Some areas of the control panel unit possess a high electrical potential, so exercise caution to avoid an electrical shock.

• When handling the LCD shield and LCD protective plate, be careful not to leave fingerprints or other marks on them.

3.2 Replacing an Amp Unit

3.2.1 Replacing an Amp

To remove an amp, unfasten one screw each at the top and bottom of the amp, then grasp the amp’s knob to pull it out toward you.

When remounting the LCD shield plate, ensure that the circled areas in the photograph below are covered by the control panel shield and fasten both screws at the same time. (Also tighten the ground lead at the same time.)

Fig. 3-3-7

CAUTION

When removing or mounting the control panel shield either while replacing the inverter board or while cleaning or replacing the main control panel’s keys, because the red circled areas are not present on the protective sheet applied to the control panel shield, be careful not to cut your fingers on the corners.

3.3.2 Replacing the LCD Panel

(1) Remove the LCD shield plate (see Subsection 3.3.1, “Replacing the Inverter Board”). (2) Disconnect the two cables from connectors CN2 and CN3 on the inverter board.

3.3.4 Replacing and Cleaning the Control Panel Keys

The control panel keys of the WR1000 consist of two types of keys: sheet keys (for amp control panel keys) and rubber switch-keys (for main control panel keys and menu keys).

Replacing Sheet Keys and Menu Sheets

Either replace the pertinent sheet as required or replace the entire control panel cover.

Cleaning and Replacing the Rubber Switch-Keys

If the key response becomes unsatisfactory, first try cleaning the rubber switch-key concerned. If the key response does not improve even after cleaning, replace that rubber switch-key.

(1) Remove the main control panel key board.

a. Remove the key control board (see Subsection 3.3.5, “Replacing the Key Control Board”). b. Remove the three screws then remove both the control panel mounting plate and control panel shield.

3. DISASSEMBLY AND REASSEMBLY

(3) Clean the keytops.

The structure of each key board conforms to the figure below.

Fig. 3-3-20

Clean the keytops as follows. a. Wipe off the stains from the contact area on the board side, using alcohol or its equivalent.

b. Remove dust and other foreign matter from the contact area of each rubber switch (the black rubber

part).

CAUTION

Because the rubber switches have contact areas made of conductive rubber, using alcohol or other chemicals to clean them may cause deterioration. As a result, never use alcohol or other chemical solvents to wipe off the rubber switch-keys.

If the key response does not improve even after cleaning, replace that rubber switch-key or the entire key board.

3.3.5 Replacing the Key Control Board

(1) In the direction indicated by the white arrow below, pull the jog/shuttle dial off of the front of the control

panel.

3.6 Replacing the Main Control Board

The procedure for replacing the main control board varies slightly with the WR1000’s channel configuration (8 or 16 channels).

16-Channel Model

The 16-channel model is equipped with the two main control boards listed below.

• A main control board for controlling Channels 1 through 8 and various functions.

• A main control board for controlling Channels 9 through 16.

8-Channel Model

The 8-channel model is equipped with the single main control board listed below.

• A main control board for controlling Channels 1 through 8 and various functions.

3.6.1 Replacing the 16-CH Control Board (16-Channel Model only)

3.6.2 Replacing the Main Control Board

(1) Remove the bottom plate (see Subsection 3.6.1, “Replacing the 16-CH Control Board”). (2) Remove the front cover (see Section 3.3, “Replacing the Control Panel Unit”).

If the FDD (Floppy Disk Drive) is installed, remove the FDD control board. If the SCSI interface and either the MODD (Magneto-Optic Disk Drive) or HDD (Hard Disk Drive) is installed, remove the SCSI control board. For instructions on removing the above-mentioned memory devices, see Section 3.9, “Replacing the Internal and External Memory Devices.”

If you have a 16-channel model, remove the 16-CH control board (see Subsection 3.6.1, “Replacing the 16-CH Control Board”).

(3) Unfasten the seven screws (or , with a 16-channel model, the three screws and four spacers), disconnect

the cables from the four connectors (also disconnect the cable from P1019 if the FDD control board is mounted and from P1026 if the SCSI control board is mounted), then replace the main control board.

NOTE

The time and date settings are reset whenever the battery is replaced. Be sure to correctly set the time and date before returning the WR1000 to the customer.

DANGER

• The battery may explode if it is not properly replaced.

CAUTION

• Do not replace the battery with a non-standard substitute (use only a battery with the same part number or its equivalent).

• Dispose of a used battery according to local ordinances and other regulations stipulated in your region. If you are unsure how to dispose of batteries, contact your sales representative or nearest Graphtec vendor.

5. ADJUSTMENTS

5.1 Adjusting the V Amp Overshoot

Always perform the overshoot adjustment described below whenever a V amp has been replaced.

Preparations

(1) Have on hand an oscilloscope that can be set to output square waves at a ±2 V output level and a 1-Hz

frequency. (2) Prior to measurement, mutually connect the GND terminals of the oscillator and the WR1000. (3) Perform adjustment using a precision screwdriver with a plastic handle. (A precision screwdriver with a

metallic handle cannot be used because it causes noise to mix with the waveforms.) (4) To perform adjustment, remove the plastic rivet covering the adjustment hole for each trimmer, as shown

in the photograph below.
