配置
在冗余配置中，两个PM891单元安装在两个独立的
DIN导轨。如果有足够的空间，可将装置安装在
铁路上的嘈杂声。
使用以下步骤沿DIN导轨安装处理器单元：
1.安装处理器单元。
2.将通信接口安装在CEX总线左侧
处理器单元。如果使用BC810，则段的配置应为
考虑过的。如果不使用BC810，则可以在
以任何优选方式提供两个CPU。
3.轻轻地将单元压在一起，确保CEX总线正确
通过单元上的连接器连接。
4.如果使用BC810，则将TK851电缆连接到两个BC810。如果使用了BC810
不使用时，将CEX总线延长电缆TK850安装到远的单元
远离处理器单元，或者如果没有安装单元，则直接连接到处理器单元上的CEXBus。CEX总线延长电缆必须连接到：
两个CPU，无论是否有任何其他CEX总线单元（图29

Station. The marking has no relevance to the physical placement of the CPUs.
Any CPU can become the Primary CPU. For BC820 this is handled by setting the
switch on TP850 to either "Lo" or "Up”.
If BC810 is used, both CPUs should be powered from the same supply (single or
redundant). For redundant power supply, see Figure 51 on page 148.
Connection to the optical ModuleBus is identical to that for the processor unit
and for the FCI in S800 I/O (Figure 60 on page 169).

8. The CPUs are supplied with internal back-up batteries. When the batteries are
to be used, place them in the Internal Battery Holder (Figure 68 on page 201).
When the external SB821/SB822 battery units are to be used, install them
according to the instructions in Installing the SB821 External Battery Unit on
page 151 / Installing the SB822 Rechargeable External Battery Unit on page
152.
Do not place the internal back-up battery in the battery holder until the AC 800M
Controller has been powered-up normally and the memory back-up function has
been activated, that is, the B(attery) LED flashes. If no normal power supply is
connected to the processor unit with the battery in place, then the CPU memory
will immediately start to consume battery power.
Always install a fresh internal or external battery at the end of the installation
phase. The original battery is heavily utilized due to frequent blackouts during
system installation.

Installing the PM891 Processor Unit in Redundant
Configuration
In redundant configuration, two PM891 units are mounted on two separate
DIN-rails. If sufficient space is available, the units can be mounted on the same
DIN-rail.
Use the following procedure to install the processor units along the DIN-rail:
1. Mount the processor units.
2. Mount the communication interfaces on the CEX-Bus to the left of the
processor unit. If BC810 are used, the configuration of the segments should be
considered. If BC810 are not used, the interfaces can be divided between the
two CPUs in any preferred way.
3. Press the units gently together and ensure that the CEX-Bus is correctly
connected, through the connector on the unit.
4. If BC810 are used, connect the TK851 cable to the two BC810. If BC810 are
not used, mount the CEX-Bus extension cable TK850 to the units at farthest
away from the processor units or, if no units are mounted, directly to the CEXBus on the processor unit. The CEX-Bus extension cable must be connected to
both CPUs whether or not there are any other CEX-Bus units (Figure 29 on
page 99).
5. Connect the RCU Data Link Cable (TK855) and the RCU Control Link Cable
(TK856) to both CPUs.
The RCU Data Link Cable (TK855) and the RCU Control Link Cable (TK856)
must not be replaced by similar cables. Using another cable will disable the
identification of the CPUs in the Control Builder and Operator Station.
The CPU connected to the RCU Control Link Cable (TK856) connector marked
“UPPER” will be defined as “UPPER” in the Control Builder and Operator
Station. The marking has no relevance to the physical placement of the CPUs.
Any CPU can become the Primary CPU.
