5-2. Cautions in handling the mechanism

(1)Cut washers removed at the time of part replacement etc. should be

replaced with new ones without fail.

(2) Because no volume adjustment is available in this mechanism, cleaning or

part replacement should be performed if the setting is not satisfied.

(3) About oil

a) Be sure to use the specified oil. (If any oil other than the specified oil is

used, various troubles will occur.)

b) When lubricating the bearing, be sure to oil free from foreign particles

such as dust. (If oil in which foreign particles such as dust are mixed is used, it will cause wear and seizure to the bearing.)

c) The term "One drop of oil" here means the amount of oil on the point of

a needle etc. shown in Fig.1.

(4) Repairing of circuits, final adjustment of running system, etc. should be

performed with the cassette controller assembly installed in the mechanism.

(5) When operating the mechanism singly, apply voltage to the loading motor

to drive it. The voltage between the terminals should be 3 to 4V DC. (Do not apply external voltage to the loading motor with the mechanism connected with the main circuit board. Doing so could cause a failure.) (Turning the gears forcedly by hand may cause them to get damaged.) When placing the mechanism singly, use an appropriate spacer so that the capstan motor is not rubbed.

(6) When installing the cassette controller, push the portion indicated by "A" in

Fig.2. Do not push other portions.

(7) Take care not to deform the components of the mechanism.

6. ADJUSTING AND CHECKING OF MECHANISM

The items described here are relevant to the general on-site servicing (field service). This section does not cover adjustment and replacement for which sophisticated equipment, jigs and techniques are required. In order to maintain the initial characteristics of the mechanism, it is necessary to perform maintenance and inspection and also it is essential not to damage the tape etc. In the case of an adjustment that requires a jig, be sure to use the specified jig.

(1) When adjusting and checking the mechanism, be sure to see that the power supply and the status are as indicated in

Caution on the title.

(2) Do not apply external voltage to the loading motor with the mechanism connected with the main circuit board. (Doing

so could cause a failure.)

(3) When running the tape, be sure to do so with the cassette controller assembly installed.

6-1. Checking of PB (REC) winding torque

AC adapter used, Cassette controller assembly installed

(1) Set the torque cassette with the cassette controller installed in the mechanism. In the SP record mode (or in the PB mode

if signals have been SP-recorded on the tape), check that the winding torque is within spec.

<Spec for PB (REC) winding torque>(If there is a torque ripple, read the center value.)

0.7+0.2/-0.05N·m, Ripple: 0.1mN·m or less

6-2. Checking of VS-REW winding torque

AC adapter used, Cassette controller assembly not installed (Mechanism only)

(1) Remove the cassette controller, turn ON the down SW while referring to 8-3, operate

in the test mode (T01) and select the VS-REW mode.

(2) Set the torque gauge in the S reel table, push the tip of the tension pole with your finger

in the direction shown by Arrow A to release the tension band, and check that the winding torque is within spec. (Fig.1) (Do not apply the own weight of the torque gauge or rotate it during measurement.)

<Spec for VS-REW winding torque> (If there is a torque ripple, read the center value.)

1.5 ± 0.15N·m, Ripple: 0.15mN·m or less

(3) After checking the winding torque, remove the torque gauge and turn OFF the down

SW. The mechanism will automatically go into the standby mode.

Fig.1 How to release the tension

band when measuring the VS-REW winding torque

6-3. Checking of height of reel table

3 to 4V DC, Cassette controller assembly not installed (Mechanism only) (1) Remove the cassette controller. (Refer to 8-2.)

(2) Apply 3 to 4V DC to the loading motor while referring to 8-1 and select the

PB mode.

(3) Fit the holes of the master plane to the two guides (portions A and B) shown

in the Fig.2, taking great care not to allow master plane to strike the running parts such as the drum and guide roller or the MIC contact.

(4) Using a pair of vernier calipers etc., measure the heights of the reel-supporting

faces of the S reel table and Tu reel table from the top face of the master plane and check that the measured heights satisfy the set values. (Fig.3) When measuring the height of the S reel table, push the tip of the tension pole with your finger in the direction shown by Arrow A to release the tension band. (Fig.1)

(5) If the measured height does not satisfy the set value, replace the reel table

and make checking again.

<Note> After replacement, select the L start mode (see 8-1) and check that the

reel table rotates smoothly.

6-4. Checking and adjusting of tension pole position during REC (PB)

3 to 4V DC, Cassette controller assembly not installed (Mechanism only)

(1) Checking

Check that the tension pole is located in the prescribed position as shown in Fig.4 at the start of a 60-minute tape. If the tension pole is not located in the prescribed position, take out the tape and make adjustment according to the procedure shown below.

(2) Adjusting (See Fig.4.)

1. Select the PB mode without setting a tape.

2. Slightly loosen the screw 1 (to such an extent that the T band adjustment base 2 can be moved.)

3. If the tension pole is dislocated inward from the prescribed position, shift the T band adjustment base 2 in the direction shown by Arrow (A). If it is dislocated outward from the prescribed position, shift the T band adjustment base 2 in the direction shown by Arrow (B). Then fix the T band adjustment base 2 with the screw 1. (For how much the T band adjustment base is to be shifted, refer to Fig.4.)

4. Check the tension pole position as described in "(1) Checking" above.

5. If out of position, make readjustment.

6-5. Checking and adjusting of REC (PB) back tension torque

AC adapter used, Cassette controller assembly installed (1) Checking

Set the torque cassette (SD-1015). In the SP record mode (or in the PB mode if signals have been SP-recorded on the tape), check that the feed-side torque is within the following spec.

<Spec>(If there is a torque ripple, read the center value.)

9. METHOD OF ADJUSTING THE ELECTRIC CIRCUIT

-Before making adjustment-

· It seems that, in most cases, this adjusting method is used when it becomes necessary to adjust the electric circuit as a result of replacement of worn mechanism parts or the video head. When adjusting the electric circuit, check that the mechanism operates properly (the mechanism is adjusted completely). If a failure occurs in the electric circuit, be sure to locate the fault using a measuring instrument and then perform repairing, replacement and adjustment, as described in this adjusting method. Avoid performing undue adjustments etc. without using proper measuring instruments.

· The electric circuit components in the circuit board unit of this product are densely-packed into packages. Most of them are surfacemounted for downsizing. When replacing components in servicing the product, perform replacement work swiftly with a soldering iron. In general, surface-mounted components are inferior in heat resistance to large-sized discrete components used in TV sets, stationary decks, etc. Heating the electrode of a surface-mounted component with a soldering iron for a long time needlessly will therefore lead to a failure. Take great care not to do so. Take special care in this respect when replacing chip multilayer capacitors in particular. We recommend you to use a ceramic soldering iron (Tip temperature: 250°C, Contact time: 5 seconds or less).

1) Adjust the lighting so that the illumination intensity is about 3000 lx and that uniform illumination is provided on the whole pattern. (It is desirable that two or more lamps be used as light sources.) Set the color temperature at 3200K.

2) The test pattern used should be free from stains and color deterioration.

3) If a failure occurs in the electric circuit, be sure to locate the fault using a measuring instrument and perform repairing or replacement before making adjustment of camera section.

(2) Adjustment remote control RRMCG0033TASA

The adjustment remote control (RRMCG0033TASA) is used to adjust the camera section of this unit. Adjustment is made by writing data into the E2PROM(IC705) at particular addresses using the remote control via the microcomputer.

1) To adjust the camera Press the "CONTINUE" key and then press the "CAM ADJ" key. The following display will appear on the LCD screen, allowing you to make adjustment.

5) After completion of adjustment Press the "CONTINUE" key to make the display "CAM ADJ" disappear. Note: Before pressing the "CONTINUE" key, check that the unit is not in the auto focus adjustment mode or the camera signal

system adjustment mode (described later).

Æ Camera section adjustment mode The auto focus adjustment mode and the camera signal system adjustment mode are used for adjustment of the camera section.

Note: The adjustment data are stored in the E

PROM as shown below. When making changes, it is therefore necessary to perform

rewriting of data and checking of the latest data.

1) E2PROM (IC705) on main unit

Lens-related data and signal system adjustment data

(3) Auto focus adjustment mode

· The camera of this unit features automatic focussing by means of a microcomputer. The auto focus circuit of this unit performs focusing operation based on the principle that the high frequency component in the video signal increases as focus is achieved. In addition, in order to achieve a large magnification with a small-size lens, the inner focus system is employed in which a master lens (rear lens) is moved forward and backward for focusing. This inner focus system enables full range focussing with a focal length range of 10 mm to infinite distance. However, because the maximum allowable distance from the closest subject to the tele end is 1.5 m, a subject less than 1.5 m away from the tele end cannot be focused on if it is shot at the tele end. In such cases, zooming-out is performed automatically for focusing.

The major factors of the auto focus system are as follows:

• Detection of master lens position

• Detection of iris position

• Detection of zoom lens reference position

These detection data are stored in the E

PROM.

Therefore (3) auto focus adjustment should be performed in the following cases.

• When the lens is replaced

• When the CCD is replaced

• When the E2PROM is replaced

• When the CCD circuit board and CAMHEAD circuit board are replaced

1) How to enter the auto focus adjustment mode Set the data value at address "13FE" to " 01".

]

The screen will be white-faded temporarily and the auto focus adjustment mode will be established.

* When the auto focus adjustment mode is established, make adjustment according to "(5) Camera adjusting procedure". * In the auto focus adjustment mode, lens operation cannot be performed.

2) How to enter the normal mode Set the data value at address "13FE" to " FF".

]

The screen will be white-faded temporarily and the normal mode will be established.

]

Pressing the "CONTINUE" key will make the display "CAM ADJ" disappear and make it possible to perform normal operation.

9-2-4. Adjusting procedure

Item

(1) Adjustment of auto focus

The following adjustments are performed automatically by establishing the auto focus adjustment mode and writing the following data at address "13FD" sequentially. The adjustment items are as shown in the table below. When an adjustment is completed normally, data "FF" is written, which should be confirmed before proceeding to the next adjustment.

Address Data Adjustment item

13FD 0012 Adjustment of wide end

0008 Adjustment of tele end focus ∞ position 0006 Adjustment of wide end focus ∞ position 000D Adjustment of zoom tracking

Note 1: During the adjustment of ∞ position, a subject should be shot actually. Make this adjustment while shooting a subject with

a clear-cut outline. In the case of the adjustment of tele end focus ∞ position in particular, if it is performed without shooting a distant subject actually, the ∞ position will not be adjusted properly.

Adjustment of wide end focus ∞ position: 3 m or more Adjustment of tele end focus ∞ position: 50 m or more

Note 2: In the case of the adjustment of ∞ position, the depth of field is important in insuring accuracy. If the depth of field is deep,

the ∞ position may be adjusted improperly the subject hardly falls out of focus. Make this adjustment with the depth of field being shallow (the iris opened).

It is possible to open the iris using the high-speed shutter.

1. Establish the normal mode.

2. Call the V-V adjust sports mode in normal operation. (Refer to the instruction manual.)

3. Display "CAM ADJ" by using the remote control for servicing.

4. Establish the auto focus adjustment mode.

5. Perform the adjustment of ∞ position.

6. After the completion of the adjustment of ∞ position, set the V-V adjust back to the off position. After canceling the auto focus adjustment mode (to write the data " FF" in the address "13FE"), set to the adjustment mode while in the camera signal system adjustment mode (to write the data " 00" in the address "0000").

Adjustment method

(2) Basic adjustment of iris

It is performed to adjust the operating point of the hall element installed in the iris meter.
