3BHE030579R0003控制器模块
工作温度CPX 928需要强制空气冷却才能正常工作在高于50℃的环境温度下运行（122F）。一台70 CFM的风扇（包括过滤器）应位于机架插槽1下方，包含：CPU。
风扇组件（IC697ACC721、IC697ACC724和IC697ACC744）可直接安装在
IC697机架。请参阅适用的可编程程序有关详细信息，请参阅控制器安装手册。
安装这是OEM、系统集成商的责任，或最终用户正确安装PLC设备，以便：操作安全可靠。产品手册提供
有关安装、启动和的详细信息正确使用PLC设备。装置手动，随PLC编程一起提供软件，描述如何正确安装设备如果PLC安装必须符合支持标准，如FCC或CE指令，请参考符合安装要求，符合标准，随PLC编程一起提供软件，以获取其他指南。未参考适用的可编程控制器安装手册，不得尝试安装。
将电池连接至模块上的任一电池连接器（见图2）。
将拨动开关置于停止位置。将钥匙开关置于记忆保护关闭位置。
确保机架电源已关闭。
将CPX 928模块安装在机架0的插槽1中（请参阅图1）。
打开电源。模块应通电，左上角（正常）LED应闪烁。当诊断有成功完成，左上角的LED保持亮起
第二个（运行）和第三个（EN）LED熄灭第四个（左下）LED（MEM保护）在以下情况下熄灭：
钥匙开关处于断开位置。CPU现在准备编程（如果并联连接CPU可编程而不考虑键位置）。
验证程序后，切换开关可以移动到适当的操作模式
位置启用输出时运行，运行输出被禁用或停止。七LED指示拨动开关的位置，存储器保护状态、串行端口活动状态，以及程序的状态。
Operating Temperature
The CPX 928 requires forced air cooling for proper
operation in ambient temperatures greater than 50C
(122F). A fan capable of 70 CFM (including filters)
should be located beneath slot 1 of the rack containing
the CPU.
Fan assemblies (IC697ACC 721, IC697ACC724, and
IC697ACC744) can be ordered for direct mounting on
the IC697 rack. Refer to the applicable Programmable
Controller Installation Manual for detailed information.
Installation
It is the responsibility of the OEM, system integrator,
or end user to properly install the PLC equipment for
safe and reliable operation. Product manuals provide
detailed information about installation, startup, and
proper use of the PLC equipment. The installation
manual, shipped with your PLC programming
software, describes how to properly install the
equipment.
If the PLC installation must comply with supported
standards, such as FCC or CE Directives, please refer
to the Installation Requirements for Conformance to
Standards, shipped with the PLC programming
software, for additional guidelines. Installation should not be attempted without referring to the applicable Programmable Controller Installation Manual.
Connect the battery to either of the battery connectors on the module (see Figure 2).
Put the toggle switch in the STOP position.
Put the keyswitch in the Memory Protection OFF position.
Make sure that rack power is off.
Install the CPX 928 module in slot 1 of rack 0 (see
Figure 1).
Turn on power.
The module should power up and the top left (OK)
LED should blink. When the diagnostics have
completed successfully, the top left LED stays on and
the second (RUN) and third (EN) LEDs are off. The
fourth (bottom left) LED (MEM PROTECT) is off if
the keyswitch is in the OFF position. The CPU is now
ready to be programmed (if connected parallel, the
CPU can be programmed regardless of key position).
After the program has been verified the toggle switch
can be moved to the appropriate operation mode
position; RUN WITH OUTPUTS ENABLED, RUN
WITH OUTPUTS DISABLED, or STOP. The seven
LEDs indicate the position of the toggle switch,
memory protection status, status of serial port activity,
and the state of the program.
