*1: Replacing the battery
For the replacement procedure, refer to chapter 5.1.1.1 “Replacing the
Battery” of the DX200 MAINTENANCE MANUAL.
*2: Replacing the YCP21 circuit board
For the replacement procedure, refer to chapter 5.1.1.2 “Replacing the
CPU circuit board (JANCD-YCP21-E)” of the DX200 MAINTENANCE
MANUAL.
When the power
is turned ON, the
maintenance
mode starts
though the mode
is not selected
and the
alarm”Memory
battery weak” is
displayed.“
‘F’ The data

robot I/F
circuit
board
(YIF01)
is invalid
value.
The battery
malfunctions.
Battery
failure
-Turn the power OFF then back ON.
-Check the connection and insertion
status of the YIF01 circuit board (CN110/
BAT) connector.
-When the LED of the YIF01 circuit
board(D5/BAT) is ON, replace the
battery. After replacing the battery, load
the CMOS.BIN file saved before the error
occurs or the CMOSBK.BIN file saved in
the automatic backup function in the
maintenance mode. (refer to *1)
The IC
storing the
data is out
of order.
YIF circuit
board
failure
-Turn the power OFF then back ON.
-If the error occurs again, remove the YIF
circuit board from the CPU rack and
reinstall it.
-If the error occurs again though reinstall
them, replace the YIF circuit board. After
replacing the board, load the CMOS.BIN
file saved before the error occurs or the
CMOSBK.BIN file saved in the automatic
backup function in the maintenance
mode. (refer to *4)
When the power

is not selected.
The robot I/F circuit
board(YIF) is out of
order or malfunctions.
YIF circuit
board
failure
-Turn the power OFF then back ON.
-If the error occurs again, remove the YIF
circuit board from the CPU rack and
reinstall it.
-If the error occurs again though reinstall
them, replace the YIF circuit board. After
replacing the board, load the CMOS.BIN
file saved before the error occurs or the
CMOSBK.BIN file saved in the automatic
backup function in the maintenance
mode. (refer to *4)
The CF card data in
the YCP21 circuit
board is invalid value.
CF card
(inserted
into the
YCP21
circuit board)
failure
-Turn the power OFF then back ON.
-If the error occurs again, remove the CF
card from the YCP21 circuit board and
reinstall it.
-If the error occurs again, replace the CF
card of YCP21 circuit board. After
replacing it, load the CMOS.BIN file
saved before the error occurs or
CMOSBK.BIN file saved in the automatic
backup function in the maintenance
mode. (refer to *8)
