1.产 品 详 情 资 料：
PM8xx处理器单元上的B（电池）LED指示灯闪烁内部电池•更换PM8xx内部电池SB821：•检查外部电池连接。如果情况依然存在：•更换外部电池，请参阅第195页的SB821外部电池单元。SB822：•检查外部电池连接。如果SB822上的充电LED和/或电源LED关闭：•检查24V电源连接。如果情况依然存在：•更换锂离子电池组件，请参阅第197页的SB822可充电外部电池单元。电源故障后系统时间不正确更换外部电池。R（运行）和F（故障）指示灯均不亮CI851板正在重新启动或配置过程中。留出时间完成。如果该情况持续存在，并且CEX总线上的所有其他单元都有未点亮的LED：•检查包括CI851在内的有效硬件配置是否已下载到控制器。•检查PM8xx处理器单元内的CEX总线保险丝。•从PM8xx处理器单元启动复位信号（INIT）。•更换CI851装置。F（故障）LED亮起检查所有电缆和连接器是否损坏、松动或接线不正确。•必要时进行维修。R（un）LED闪烁检查相关单元是否正在发送数据。检查CI851板是否正在重新启动或配置过程中。如果是这样的话，请留出时间进行最终确定。如果情况仍然存在：•停止应用程序并启动重新启动。•更换CI851板。
B(attery) LED indicator on PM8xx processor unit is flashing Internal battery • Renew the PM8xx internal battery SB821: • Check external battery connections. If condition persists: • Renew the External battery, see SB821 External Battery Unit on page 195. SB822: • Check external battery connections. If Charge LED and or Power LED on SB822 are turned off: • Check 24V supply connections. If condition persists: • Renew the Li-Ion battery package, see SB822 Rechargeable External Battery Unit on page 197. The system time is incorrect following a power failure Renew the External Battery.Neither R(un) nor F(ault) LEDs are ON The CI851 board is in the process of being restarted or configured. Allow time for this to finalize. If the condition persists, and all other units on the CEX-Bus have non-illuminated LEDs: • Check that a valid HW configuration including the CI851 is downloaded to the controller. • Check the CEX-Bus fuse inside the PM8xx processor unit. • Initiate a reset signal (INIT) from the PM8xx processor unit. • Replace the CI851 unit. F(ault) LED is ON Check all cables and connectors for damage, loose or incorrect terminations. • Repair as necessary. R(un) LED is flashing Check that the relevant units are sending data. Check if the CI851 board is in the process of being restarted or configured. If so, allow time for this finalize. If the condition persists: • Halt the application program and initiate a restart. • Replace the CI851 board.
