ABB BCU-12 3AUA0000110430控制单元
进行跳线修改时必须小心，以防止设置或连接不当。设置不当可能导致装置损坏。修改任何未标记为“用户可配置”的跳线将使保修失效，并可能损坏设备。VMIVME-7750的默认跳线条件在表1-1至表1-7中用粗体文本表示。注：BIOS具有密码保护功能（当前未启用），可随意访问装置的CMOS设置屏幕。密码清除跳线允许用户在忘记密码的情况下清除密码。清除CMOS密码：1。关闭装置电源。2.暂时短接E3的针脚约5秒。3.给装置通电。当设备重新通电时，CMOS密码将被清除。电源要求VMIVME-7750需要来自VME背板的+5V、+12V和-12V。以下是电压和电流要求。电源电流（典型）电流（最大）+5V 5.8A 7A+12V 105mA 200mA-12V 50mA 75mA VMIVME-7750根据PMC规范为PMC现场供电。+5V电源上提供的最大电流为每个PMC站点1.5A。每个PMC现场+3.3V电源上提供的最大电流为1.5A。
Care must be taken when making jumper modifications to ensure against improper
settings or connections. Improper settings may result in damage to the unit.
Modifying any jumper not marked “User Configurable” will void the Warranty and
may damage the unit. The default jumper condition of the VMIVME-7750 is
expressed in Table 1-1 through Table 1-7 with bold text in the table cells.NOTE: The BIOS has the capability (not currently enabled) of password protecting
casual access to the unit’s CMOS set-up screens. The Password Clear jumper allows
the user to clear the password in the case of a forgotten password.
To clear the CMOS password:
1. Turn off power to the unit.
2. Momentarily short the pins of E3 for approximately five seconds.
3. Power up the unit.
When power is reapplied to the unit, the CMOS password will be cleared.Power Requirements
The VMIVME-7750 requires +5V, +12V and -12V from the VME backplane. Below are
the voltage and current requirements.
Supply Current (Typical) Current (Maximum)
+5V 5.8A 7A
+12V 105mA 200mA
-12V 50mA 75mA
The VMIVME-7750 provides power to the PMC site in accordance with the PMC
specification. The maximum current provided on the +5V supply is 1.5A per PMC
site. The maximum current provided on the +3.3V supply is 1.5A per PMC site.
