如果內(nèi)存?zhèn)溆秒姵仉妷簽樘?，無法在斷電情況下保持內(nèi)存；否則它保持關(guān)閉。如果此LED亮起，則必須在之前更換鋰電池從機架上斷開電源，或PLC內(nèi)存可能丟失。
輸入過壓保護裝置此信息適用于所有具有六個端子的90-30系列電源董事會。
該電源的過電壓保護裝置在內(nèi)部連接至用戶端子排上的針腳4。
該引腳通常連接到機架接地（引腳3）帶有出廠時安裝的跳線帶。
如果過電壓保護不是必需的，或者是上游提供的，可以通過刪除從針腳3和4上跨接導(dǎo)線。
如果要對此電源進(jìn)行高壓測試，則必須在通過拆除接線條跳線帶進(jìn)行測試。
重新啟用過電壓保護通過重新安裝皮帶過電流保護裝置（所有電源）進(jìn)行測試后
5V邏輯輸出被電子限制為3.5安培（大容量電源為7安培）。
內(nèi)部感應(yīng)到過載（包括短路），導(dǎo)致電源關(guān)閉。
電源將不斷嘗試重新啟動，直到過載消除。
中的內(nèi)部保險絲輸入行作為備份提供。電源通常會在保險絲熔斷之前關(guān)閉。保險絲還可防止內(nèi)部電源故障。
時序圖下面的時序圖顯示了直流輸入與直流輸出以及與電源設(shè)備生成的電源設(shè)備正常信號（PSOK）。首次通電時，PSOK信號錯誤。
+5V電壓后，該線保持錯誤至少20毫秒總線在規(guī)格范圍內(nèi)，然后就變成了現(xiàn)實。
如果輸入電源中斷，+5V總線將保持在規(guī)格范圍內(nèi)，PSOK將保持真實至少10毫秒。然后PSOK變?yōu)閒alse。+5V總線將保持不變至少4毫秒，以允許有序關(guān)閉系統(tǒng)。
串行端口連接器僅在安裝在基板上的電源中起作用也包含CPU的。串行端口在安裝在擴展或遠(yuǎn)程基板中。
連接到串行端口的任何設(shè)備，使用來自Series 90-30的+5 VDC電源計算最大功耗時必須包括電源（參見第12章中的標(biāo)題“電源負(fù)載計算”）。

Status Indicator Lights on all Power Supplies
Four LEDs are located on the upper right front of the power supply faceplate. The purpose of
these LEDs is as follows:
PWR
The top green LED, labeled PWR, provides an indication of the operating state of the
power supply. The LED is ON when the power supply has a correct source of power
and is operating properly, and OFF when a power supply fault occurs or power is not
applied.
OK
The second green LED, labeled OK, is steady ON if the PLC is operating properly, and
OFF if a problem is detected by the PLC.
RUN
The third green LED, labeled RUN, is steady ON when the PLC is in the RUN mode.
BATT
The bottom red LED, labeled BATT, will be ON if the memory backup battery voltage
is too low to maintain the memory under a loss of power condition; otherwise it
remains OFF. If this LED is ON, the Lithium battery must be replaced before
removing power from the rack, or PLC memory may be lost.
Input Overvoltage Protection Devices
This information applies to all Series 90-30 power supplies that have six–terminal
boards. The overvoltage protection devices for this power supply are connected internally
to pin 4 on the user terminal strip. This pin is normally connected to frame ground (pin 3)
with the supplied jumper strap which is installed at the factory. If overvoltage protection
is not required or is supplied upstream, this feature can be disabled by removing the
jumper strap from pins 3 and 4.
If you want to Hi-pot test this supply, overvoltage protection must be disabled during
the test by removing the terminal strip jumper strap. Re-enable overvoltage protection
after testing by reinstalling the strap
Overcurrent Protection (all Supplies)
The 5V logic output is electronically limited to 3.5 amps (7 amps for high capacity supplies). An overload (including short circuits) is sensed internally and causes the supply to shut down. The supply will continually try to restart until the overload is removed. An internal fuse in the input line is provided as a backup. The supply will usually shut down before the fuse blows. The fuse also protects against internal supply faults. Timing Diagram The timing diagram below shows the relationship of the DC input to the DC outputs and to the Power Supply OK signal (PSOK) generated by the power supply. When power is first applied, the PSOK signal goes false. This line remains false for a minimum of 20 msec after the +5V bus is within specifications, then it becomes true. If input power is interrupted, the +5V bus will remain within specifications and PSOK will remain true a minimum of 10 milliseconds. PSOK then goes false. The +5V bus will remain within specifications for an additional 4 milliseconds minimum to allow an orderly shutdown of the system.
The serial port connector is only functional in a power supply that is installed in a baseplate that also contains the CPU. The serial port is not functional on a power supply that is installed in an expansion or remote baseplate. Any device connected to the serial port that uses +5 VDC power from the Series 90-30 power supply must be included in the calculation for maximum power consumption (see the heading “Power Supply Loading Calculations” in Chapter 12). CPU Serial Port Information The serial port connector on the power supply accesses the CPU serial port, which is a feature of all Series 90-30 CPUs. See Chapter 5, “CPUs” for infomation on this serial port.
