Indication
U10
Dew formation
If the voltage at the dew detection input terminal is over 1.36VDC, it
judged DEW.
l
“U10” is indicated on the FIP when the dew is detected.
l
“10” is memorized on the self- diagnosis history.
l
The mechanism is unloaded to the LOAD position and wait until the dew
is extinct when a tape is in the VCR.
l
Cassette in operation is not accepted until the dew is extinct when a
cassette tape is not in the VCR.
l
The dew is judged extinct and the VCR is returned to normal condition
after the voltage at the dew detection input terminal becomes less than
1.36V DC, and moreover 80 minutes passed from then.
Yes
U11
Cylinder clogs during the PLAY mode.
Cleaning the
Cylinder.
Yes
H01
CYL PFG can not be detected when the cylinder starts.
If the CYL PFG could not be detected within 5 seconds when the
cylinder starts from the cylinder stop condition in tape loading
completion, and so on, the load from tape to the cylinder is ridded by
unloading until the LOAD position at once.
If the CYL PFG could not be detected within 5 seconds after that, it is
judged an Error of the cylinder system.
l
“H01” is indicated automatically, and the power is turned to off in the
DOWN position.
l
Only the power key is accepted, and the Mechanism Initial Operation is
performed.
Please check the
cylinder motor,
cylinder drive circuit
and CYL PFG signal
circuit.
Yes
H02
The CAP FG can not be detected during the Mechanism Initial
Operation (Tape rewinding by the S-Reel) in LOAD position.
When the power is turned on or the AC is input to the VCR in condition
that the mechanism is stopped at LOAD position with a mechanism
lock, if the CAP FG could not be detected over 255 pulses during first
one second of 5 seconds tape rewinding previous to the re-loading
with S-reel, that is judged a Error of the capstan system.
l
“H02” is indicated automatically, and the power is turned to off in the
DOWN position.
l
Only the power key is accepted, and the Mechanism Initial Operation is
performed.
Please check the
capstan motor,
capstan drive circuit
and CAP FG signal
circuit.
Yes
F03
The position signal can not be detected within the regulated time
for the shift to the aiming position except EJECT position during
except unloading when the mechanism position is shifted.
IF the position signal could not be detected within the regulated time
which is set depending on the distance to the aiming position when the
mechanism is shifting the position, it is judged Mechanism Lock. The
judgement depends on the input signal from the Position SW.
l
In the first detection after the mode shift is started, the detection result is
not judged an Error, and the Mechanism Initial Operation is performed.
l
If the position signal aimed to is not detected again during this
Mechanism Initial Operation, it is judged an Error, and “03” is indicated
automatically.
l
Then the mechanism stops at the position by the automatic power off,
and only the Power Key is accepted.
l
After the power is turned on, the Mechanism Initial Operation in
performed.
l
“03” is memorized on the self- diagnosis history.
Please check the
Mechanism,
Loading Motor,
Drive circuit, Drive
control signal circuit,
Position SW and the
Position SW input
signal circuit.
