按照以下步骤更换暂停的处理器单元：
1.断开电源插座与处理器单元的连接。
2.从断开RCU链路电缆和光模块总线电缆
待交换的处理器单元。
3.如果使用PM85x/PM86x，请使用一字螺丝刀松开处理器单元盖上的两个弹簧固定螺钉，然后小心地拆下
处理器单元。如果使用PM891，小心地拆下装置。
4.安装新的处理器单元（已安装正确的固件）
并拧紧螺钉。
5.将电源插座重新连接到新处理器单元。
6.重新连接光模块总线和RCU链路电缆。
7.按下更换的处理器单元上的INIT按钮。
对于PM85x/PM86x，在运行期间只能更换CPU单元，以及
而不是相关的底板。拆除底板会危及功能
CEX总线接口（如有）。
对于PM891，如果没有

更换前，新CPU必须加载正确的固件，如
现有CPU。
您无需完全断开RCU链路电缆即可：
交换暂停的处理器单元。仅断开备份CPU，从而保持
连接到主CPU的RCU链路电缆（现在运行在单个
状态）。但是，如果必须更换RCU链路电缆，请参阅更换缺陷

Replacing the Battery in an SB822 Rechargable External Battery Unit
To replace the Li-Ion battery:
1. Disconnect the TK821V020 cable connector.
2. Disconnect the 24V supply cable connector
3. Release the SB822 unit from the DIN-rail.
4. Attach a properly grounded ESD wrist strap to your wrist before you proceed.
5. Carefully remove the SB822 unit cover and identify the battery package.
6. Carefully disconnect the battery connector from the PCB.
7. Carefully remove the battery package.
8. Insert the new battery and connect. Reassemble is reverse from disassemble.
9. Install the unit.
10. Dispose of the worn battery package in an approved manner.
Online Replacement of Unit Section 5 Maintenance
206 3BSE036351-600 A
Online Replacement of Unit
Replacement online entails adding or removing units in a controller without
disturbing the execution of the running application program. Units are connected to
the CEX-Bus and the electrical ModuleBus (S800 I/O).
CEX-Bus
Communication interfaces (CI8xx) Can be removed or replaced online.
Restrictions apply, refer to the
installation section for each interface
and to Appendix A, Hardware Units.
Baseplates for CI8xx (TP8xx) Must not be replaced online.
ModuleBus
S800 I/O units Can be removed or replaced online.
Module Terminal Units (MTUs) Must not be replaced online
Redundant CPUs
Processor unit Can be removed or replaced online
(see the next following pages)
RCU Link Cables Can be removed or replaced online.
However, the following restriction
applies; you cannot replace the RCU
link cable online in a previous than 4.1
software version. For more
information, see the instructions given
in Exchanging Defect RCU Link
Cables Online on page 210.
It is not allowed to manipulate CEX bus baseplates in a powered and running
system. Before changing or removing a baseplate, all CEX modules on that
segment must be removed.
Section 5 Maintenance Exchange of CPU in Redundant Configuration without BC810/BC820
3BSE036351-600 A 207
Exchange of CPU in Redundant Configuration without
BC810/BC820
Follow the steps below to exchange a halted processor unit:
1. Disconnect the Power Supply Socket from the processor unit.
2. Disconnect the RCU link cables and optical ModuleBus cable from the
processor unit to be exchanged.
3. If PM85x/PM86x is used, use a blade screwdriver to release the two springloaded captive screws on the processor unit cover, and then carefully remove
the processor unit. If PM891 is used, carefully remove the unit.
4. Fit the new processor unit (which already has the correct firmware installed)
and tighten the screws.
5. Reconnect the Power Supply Socket to the new processor unit.
6. Reconnect the optical ModuleBus and RCU Link Cable.
7. Press the INIT push button on the replaced processor unit.
For PM85x/PM86x, only the CPU unit can be exchanged during operation, and
not the associated baseplate. Removing the baseplate jeopardizes the functioning
of CEX-bus interfaces, if any.
For PM891, the entire unit cannot be exchanged during operation, without
jeopardizing the functioning of CEX-bus interfaces, if any
Before replacing, the new CPU must be loaded with the correct firmware as in the
existing CPU.
You do not have to disconnect the RCU link cables completely in order to
exchange a halted processor unit. Disconnect only the backup CPU, thus keeping
the RCU link cables connected to the primary CPU (now running in a single
state). However, if you must replace the RCU link cables, see Exchanging Defect
RCU Link Cables Online on page 210.
The F(ault) LED of the new processor unit is temporarily lit when the power
supply is connected. This is not an indication of fault.
Pressing the INIT button initiates the restart that is required to keep the new
processor unit in redundant mode. | 731CA-35 终端显示控制器 FOXBORO 福克斯波罗 | | | |
