CAUSE
COUNTERMEASURE
1. Effect of extraneous noise
1. After ACL key is pressed or power is
turned on again :
1) If error doesn't occur, printed circuit
board is normal. Then, remove noise
sources near operation panel.
2) If error occurs again, remove noise
sources and take measure with the
following coutermeasure No.2.
2. Printed circuit board is
faulty.
2. Replace printed circuit boards with
following procedure and confirm the
operation.
1 Replace Transmission adapter
control printed circuit board.
2 Replace Transmisson adapter
communication printed circuit board.
3 Operation panel printed cicuit board.
1. Error occurrence condition
Communication between
transmission adapter
control printed circuit board
and transmission adapter
communication printed
circuit board is not
performed normally.
2. Relevant operation
1) Error indication. Central
Remote operation is
available.
2) If error is kept to detect for
a while after error occurs,
transmission error (1F) is
output.
3. Clearance
The communication
between the control printed
circuit board and
communication printed
circuit board of transmission
adaptor is performed
correctly.
1. Effect of extraneous noise
1. After RESET key on control printed
circuit board of transmission adapter
is pressed, or power is turned on
again :
1) If error doesn't occur, printed circuit
board is normal. Then, remove noise
sources near transmission adaptor.
2) If error occurs again, remove noise
sources and take measure
with the following countermeasure
No.2,3.
