Method of confi rming “Original Control unit”
and “Service Control unit”
The 0
Ω
resistor (R853) is mounted
on the “R853” silk print part
of the Service Control unit
(X53-4260-13).
维修控制单元(X53-4260-13)的
“R853”丝印部分装有0Ω电阻器
(R853)。
The shielding plate is soldered
on the Service Control unit
(X53-4260-13).
维修控制单元(X53-4260-13)
上焊有屏蔽板。

Note:
• The 0
Ω
resistor (R849 and R853) is used to differenti-
ate the destination with a visual check. These are not
connected with any PCB pattern; they are specifically
for production control. There is no need to change the
mount of these resistors.
• There is no difference between the schematic diagram
of the Service Control unit (X53-4260-13) and the sche-
matic diagram of the original Control unit (X53-4260-11).
(R849 and R853 are connected with GND (ground) only.)

注意 :
• 0Ω 电阻器 ( R849 和 R853) 用于通过目视检查区分目标。
它们不与任何 P C B 图形相连，专门用于生产控制。无须改
动安装的这些电阻器。
• 维修控制单元 ( X53-4260-13) 的原理图和原始控制单元
( X53-4260-11) 的原理图并无差别。( R849 和 R853 仅连接
GND( 接地 ))。
