Description
Serial data from DCU serial
channel (1 - 8 ch) are not re-
corded to Fixed DRU, Float-free
DRU and Long Term Device.
Serial, analog and digital data
from Junction Box (IF-8530) are
not recorded to Fixed DRU,
Float-free DRU and Long Term
Device.
Fatal system error. This indi-
cates that VDR can not be re-
booted automatically.
VDR system information can
not be acquired. Usually, this
error is recovered automatical-
ly.
Temperature of CPU system
high and long term device is
turned off.
Temperature of CPU core is
high.
Temperature of CPU board is
high.
Voltage error on CPU board.
(+3.3 V line)
Voltage error on CPU board.
(+5 V line)
Voltage error on CPU board.
(+12 V line)
Voltage error on CPU board.
(VCORE line)
Voltage of battery on CPU
board is low.
Rotation speed of CPU FAN is
low.
Rotation speed of external
FAN1 is low.
External FAN1 stopped.
Action
Restart VDR. To restart the
VDR, open the DCU door with
its key and turn on the AC and
BATTERY switches on the
power control panel, then turn
the switches on after shut-
down of the DCU. If the error
re-occurs, contact your deal-
er.
If error is not recovered auto-
matically, restart VDR. To re-
start the VDR, open the DCU
door with its key and turn on
the AC and BATTERY switch-
es on the power control panel,
then turn the switches on after
shutdown of the DCU. If it
does not recover, contact your
dealer.
