1-1. Notes on Power Supply Block

Warning on Primary Circuit Block and Electric Shock

wThe primary circuit consists of the AC inlet, the POWERswitch, and the power supply unit.Be careful not to receive an electric shock when perform-ing the maintenance and service works with the powerturned on.A primary voltage remains applied to the AC inlet, andPOWER switch even if the POWER switch is turned off.For the work that requires no current conduction, therefore,turn off the POWER switch and disconnect the powercord.

1-2. Cleaning when the Heads are Clogged

Clean using a cleaning cassette tape (specified product:BCT-HD12CL) when the video heads are clogged.For the cleaning, refer to 4-2-1. Cleaning using CleaningTape.wClean the video heads in the prescribed procedure using aspecified cleaning cassette tape. If not, the video headsmay be abrasive or damaged.

If the head clogging is not solved using a cleaning cassettetape, use cleaning cloth.For the cleaning using a cleaning cloth, clean according tothe procedure of 4-2-3. Tape Running Surface of UpperDrum and Video Heads Cleaning after confirming thecautions and preparation in 4-2-2. General Informationfor Cleaning using Cleaning Cloth.

nThe cleaning cassette tape BCT-HD12CL for HDCAMsystem can also use in MSW series.

< Top View of Cassette Compartment >



!/!-!= Cassette classification sensorsThese sensors detect the three cassette type detectiontabs of a cassette.These sensors are used to discriminate whether acassette can be used in this unit.

![ L cassette REC inhibit sensorThis sensor (switch) detects the condition of a RECinhibit plug for the MPEG IMX/Betacam SX largecassette.

!] Reel S position sensor!\ Reel L position sensor

These sensors detect whether the reel table moves tothe correct position according to the size of theinserted cassette.

!; S cassette REC inhibit sensorThis sensor (switch) detects the condition of a RECinhibit plug for the small cassette.

!' S tension regulator arm sensorThis sensor detects the position of an S tensionregulator arm. During recording and playback, theoutput signal of this sensor enters the S reel motorservo circuit, and controls the reel torque to keep aconstant S tape tension.

!, Tape end sensorThis sensor detects the end of the tape that runs in theforward direction.

!. Cassette-down (2) sensor@/ Cassette-down (1) sensor

These sensors detect the movement (position) of acassette compartment by the combination of thedetection state of the two sensors and a cassette-insensor.

@- Cassette-in sensor (R)This sensor detects whether a cassette is being insert-ed.

@= Cassette size sensorThis sensor detects whether the inserted cassette is Lsize or S size.

@[ Cassette-in sensor (L)This sensor detects whether a cassette is being insert-ed.


1 Threading motor FG sensorThis sensor detects the rotation speed of the threadingmotor. The output signal of this sensor enters thethreading motor servo circuit, and controls the thread-ing/unthreading speed to protect the tape duringthreading and unthreading operation.

2 Unthreading-end sensor3 Threading-end sensor

These sensors detect whether the threading ringreaches the threading-end or unthreading-end position.

4 T tension regulator arm sensorThis sensor detects the position of a T tension regula-tor arm. During recording and playback, the outputsignal of this sensor enters the T reel motor servocircuit, and controls the reel torque to keep a constantT tape tension.

5 Condensation sensorThis sensor detects whether the dew condensationoccurs in the unit.

6 Tape top sensorThis sensor detects the beginning of the tape, and inaddition detects the end of the tape that runs in thereverse direction.

7 Reel hub diameter sensorThis sensor detects the reel hub diameter detection tabof a cassette.The reel hub with two types of diameters (thin andthick) is available according to the length of a tapestored in a cassette. This sensor is used to discriminatethe diameter. The output signal of this sensor entersthe servo circuit of take-up and supply reel motors, andcontrols the reel rotation speed and torque during tapetransport.

8 Metal/oxide tape sensorThis sensor detects the metal tape detection tab of aBetacam/Betacam SP cassette.This sensor is used to discriminate whether the tapestored in a Betacam/Betacam SP cassette is an oxidetape or metal particle tape.

9 Tape thickness sensorThis sensor detects the tape thickness detection tab ofa cassette.This sensor is used to discriminate the thickness of thetape stored in a cassette.

1-11. Taking Out the Cassette in Tape Slacking

5. Release the lock of the board holder and open the AE-31 board in the arrow direction. (The AE-31 board isnot used in MSW-2000.)

6. Check by eye that the unit is in the state to be able towind manually the tape.

7. Pull the ME wire for a few times with short steps totake up the tape inside the cassette.m. Be careful for the tape not to catch in parts such as a

flange of a tape guide.. Do not take the ME wire off the wire holder.. The ME wire links with the T real table.

The T real table rotates about 1/24 turns clockwise (take-up direction) by pulling the ME wire about 6 mm.

8. Rotate the M gear of the threading motor block indirection of arrow shown in the EJECT label by abouta half turn to slack off the tape.

9. Pull the ME wire for a few times with short steps inthe direction of the arrow shown in the EJECT label totake up the tape inside the cassette.

1-11. Taking Out the Cassette in TapeSlacking

When slacking the tape in this unit, follow the steps belowto take out the cassette tape.nBeing careful not to damage the tape, take out the cassettetape with care.

1. Turn off the power.2. Fully loosen the fixing screw.3. Slide the knobs on upper lid (front) assembly each in

the inside. (Move the knobs to the outside to fix theupper lid (front) assembly.

4. Remove the upper lid (front) assembly.

11. Check that the ME wire is slacken.12. Open the lower control panel.13. Turn the eject knob in the direction of the arrow shown

in the label until the cassette is completely ejected.Eject knobLabel

1-12. Removing/Reattaching Plug-inBoard

m. Turn off the power and unplug the power cord before

removing/reattaching the board.. When the plug-in board is replaced, refer to the Section

1-25.

1. Fully loosen the two fixing screws.2. Remove the upper lid (rear) assembly by moving in

the direction indicated by the arrow.

3. Open the eject levers on both ends of the board in thedirection of the arrows.

4. Hold the eject levers and slowly pull the board out.

nThe AU-272 and EQ-84 boards should be removedtogether due to their structural feature.
