DVW Series


ERROR MESSAGES AND TROUBLESHOOTING

This unit features self-diagnostics.
When trouble is detected, an error code is displayed immediately in the time counter display on the lower control panel, and an error code and message appear on the video monitor connected to the VIDEO OUTPUT COMPOSITE 3 connector and the SERIAL V/A OUTPUT 4 connector.
Furthermore, for an interface error (error codes 92, 93, 96 and 98), the error location is replaced by a "sub error" message on the video monitor.
(To display error code and message on the video monitor, the CHARACTER switch on the system setup panel must be set to ON.)
 
 

Code Error message Description Detection
01 REEL TROUBLE-1 The slack of the tape is detected during threading or unthreading, and then tape protection is done. Detected when the ratio of the FG frequency at a supply reel, take-up reel and threading motor is less than the specified value.
02 REEL TROUBLE-2 The slack or breaking of the tape is detected in search, fast forward, or rewind mode, and then tape protection is done. Detected when the ratio of the FG frequency at a supply reel and take-up reel is less than the specified value.
03 REEL TROUBLE-3 The slack or breaking of the tape is detected in playback mode, or either of the lock of the supply or take-up reel is detected, and then tape protection is done. Detected when the FG frequency at a supply or take-up reel is zero (0), or when the tension detected from a tension sensor is less than 15 g.
04 REEL TROUBLE-4 It is detected that the tape does not run at the speed of designation in fast forward or rewind mode, and then tape protection is done. Depends on the comparison between the tape speed using the FG frequency at supply and take-up reels and the designated speed.
05 REEL TROUBLE-5 It is detected that the supply or take-up reel cannot stop with a cassette is not inserted, or detected that over current has been flowing to supply and take-up reels. Detected using the EG frequency or current at supply and/or take-up reels.
06 TAPE TENSION ERROR When excessive tension is detected, tape protection is done. Detected when the tension detected from a tension sensor is more than 55 g.
07 CAPSTAN TROUBLE It is detected that the tape does not run at the speed of designation in play or search mode, and tape protection is done. Detected at the tape speed detected from the FG frequency at a capstan motor.
08 DRUM TROUBLE It is detected that drum motor rotation is not normal, and then tape protection is done. Detected when the drum speed obtained from the speed FG of the drum motor is less than the specified value.
09 TH/UNTH MOTOR TIME OUT It is detected that threading or unthreading is not completed, and then tape protection is done. Detected when threading or unthreading is not completed within ten seconds after it is started.
0A THREADING TROUBLE It is detected that threading cannot be done, and then tape protection is done. Detected when the tape top sensor is acted during threading after the short FF mode is automatically entered three times.

14 FAN MOTOR TROUBLE The operation of the fan motor is defective. Detected according to the period of a ripple noise at the fan motor terminal.
20 CASSETTE COMPARTMENT MOTOR LOCK It is detected that cassette up/down operation is not completed, and then tape protection is done. Detected when cassette up/down operation is not completed within four seconds after it is started.
21 REEL SHIFT MOTOR LOCK It is detected that driving of the L pesition to S position or the 
S position to L position in the reel table is not completed, and then tape protection operation is done.		 Detect when reel table driving is not completed within four seconds after it is started.
22 REEL POSITION SENSOR TROUBLE The operation of the US position sensor of the reel table is defective. Detected when the L and S positions are detected at the same time.
90 KEY BOARD INTERFACE ERROR The interface between the KY-231 board and SS-52 board is defective. Detected when no interface signal is sent from the SS-52 board to the KY-231 board.
91 1/2 VD NOT EXIST No 1/2 VD signal input to SS-52 board is detected. Detected when no 1/2 VD signal input to the SS-52 board.
