KEBA E-CPU-186-B-12MHZ CPU模塊
默認消息亮度設(shè)置點僅適用于具有較舊硬件版本的PQM，包括真空熒光顯示器（VFD），而不是液晶顯示器（LCD）。?顯示濾波器常數(shù)：在電流和/或電壓波動較大的應(yīng)用中，可能需要顯示濾波器。此設(shè)置點允許用戶輸入PQM過濾器常數(shù)，以平均所有計量值。如果DISPLAY FILTER CONSTANT（顯示過濾器常數(shù)）設(shè)定值設(shè)置為1，PQM大約每400毫秒更新一次顯示的計量值。因此，顯示更新等于DISPLAY ILLTER CONTANT×400毫秒。要啟用設(shè)定值訪問，請按照下圖中概述的步驟操作：PQM的出廠默認訪問代碼為1。如果三次嘗試使用錯誤代碼啟用設(shè)置點訪問，則設(shè)置點訪問設(shè)置點的值將更改為禁用，必須重復(fù)上述步驟。一旦啟用設(shè)置點訪問，PROGRAM（程序）狀態(tài)指示燈將亮起。只要PROGRAM狀態(tài)指示燈保持亮起，就允許更改設(shè)置點。當達到S1 PQM SETUP\setpoint access\setpoint access on FOR（S1 PQM設(shè)置\設(shè)置點訪問\設(shè)定點訪問開啟）中編程的時間時，將禁用設(shè)置點訪問并關(guān)閉PROGRAM
The DEFAULT MESSAGE BRIGHTNESS setpoint is only applicable for PQMs with older hardware revisions that include a vacuum fluorescent display (VFD), not a liquid crystal display (LCD). ? DISPLAY FILTER CONSTANT: Display filtering may be required in applications where large fluctuations in currents and/or voltages are normally present. This setpoint allows the user to enter the PQM filter constant to average all metered values. If the DISPLAY FILTER CONSTANT setpoint is set to 1, the PQM updates the displayed metered values approximately every 400 ms. Therefore, the display updating equals DISPLAY FILTER CONSTANT × 400 ms.To enable setpoint access, follow the steps outlined in the diagram below:The factory default access code for the PQM is 1. If three attempts are made to enable setpoint access with an incorrect code, the value of the SETPOINT ACCESS setpoint changes to DISABLED and the above procedure must be repeated. Once setpoint access is enabled, the PROGRAM status indicator turns on. Setpoint alterations are allowed as long as the PROGRAM status indicator remains on. Setpoint access is be disabled and the PROGRAM status indicator turns off when: ? The time programmed in S1 PQM SETUP \ SETPOINT ACCESS \ SETPOINT ACCESS ON FOR is reached
