History Status

The History Status screen displays 64 frames, of 4 milliseconds each, from the Present Status screen. Note that the values for output volts and amps are updated once each millisecond. Alarms are listed in the sequence they occurred, within 1 millisecond resolution. The frames are stored in a buffer (a computer information storage technique). The buffer stores the frames in a first-in first-out sequence. As a new frame enters the buffer the old- est one is released.

When a designated fault occurs (see list below), the buffer stores information for the next 24 frames and then freezes (stops gathering information). At that time, the History Status screen contains 40 frames before the fault, the frame when the fault occurred, and 23 frames after the fault. This 64-page report is a very useful diagnostic tool for the operator or Liebert Global Services. Use the Up and Down pads to view the screens.
