2.9 EMERGENCY DISPLAY

Whenever some abnormal signal is input to the  syscon CPU, an
error number (E01, as an example) is displayed on the LCD mon-
itor or (in the electronic view finder).
In every error status, such the message as shown below alter
nately appear over and over.
• In an emergency mode, all operations except turning on/off the

POWER switch are ineffectual.

Example (in case of the error number E01):

Possible cause

E01

LOADING

In the case the encoder posi-
tion is not shifted to the next
point though the loading motor
has rotated in the loading direc-
tion for 4 seconds or more. This
error is defined as [E01].

1. The mechanism is locked during mode shift.
2. The mechanism is locked at the mechanism loading end,

because the encoder position is skipped during mechanism
mode shift.

3. No power is supplied to the loading MDA.

E02

UNLOADING

In the case the encoder posi-
tion is not shifted to the next
point though the loading motor
has rotated in the unloading di-
rection for 4 seconds or more.
This error is defined as [E02].

1. The mechanism is locked during mode shift.
2. The mechanism is locked at the mechanism loading end,

because the encoder position is skipped during mechanism
mode shift.

E03

TU & SUP REEL FG

In the case no REEL FG is pro-
duced for 4 seconds or more in
the capstan rotation mode after
loading was complete, the
mechanism mode is shifted to
STOP with the pinch roller set
off. This error is defined as
[E03].
However, no REEL EMG is de-
tected in the SLW/STILL mode.

1. The idler gear does not engage with the reel disk well.
2. Though the idler gear and reel disk are engaged with each

other, the tape is not wound because of overload to the
mechanism.

3. No FG pulse is output from the reel sensor.
4. No power is supplied to the reel sensor.
5. Tape transport operation takes place with a cassette having

no tape inside.

6. The tape slackens and no pulse is produced until the slack

is taken up and the tape comes into the normal status.

E04

DRUM FG

In the case there is no DRUM
FG input in the drum rotation
mode for 4 seconds or more.
This error is defined as [E04],
and the mechanism mode is
shifted to STOP with the pinch
roller set off.

1. The drum cannot be started or drum rotation is stopped be-

cause tape transport load is too high.
1) Tape tension is extremely high.
2) The tape is damaged or soiled with grease, etc.

2. The DRUM FG signal is not received by the syscon CPU.

1) Disconnection in the middle of the signal line.
2) Failure of the DRUM FG pulse generator (hall element).

3. No drum control voltage is supplied to the MDA.
4. No power is supplied to the DRUM MDA.

E06

CAPSTAN FG

In the case no CAPSTAN FG is
produced in the capstan rota-
tion mode for 2 seconds or
more. This error is defined as
[E06], and the mechanism
mode is shifted to STOP with
the pinch roller set off.
However, no CAPSTAN EMG
is detected in the STILL/FF/
REW mode.

1. The CAPSTAN FG signal is not received by the syscon

CPU.
1) Disconnection in the middle of the signal line.
2) Failure of the CAPSTAN FG pulse generator (MR ele-

ment).

2. No capstan control voltage is supplied to the MDA.
4. The capstan cannot be started or capstan rotation is

stopped because tape transport load is too high.
1) Tape tension is extremely high. (Mechanical locking)
2) The tape is damaged or soiled with grease, etc. (Tape

tangling occurs, etc.)
