System Status

The System Status screen displays the module Total Operating Hours, Enable Backlight and the Bat- tery Cycle Monitor.

Battery Cycle Monitor—Module Only

Selecting the Battery Cycle Monitor gives you access to detailed information about the module’s most recent battery discharge events. Periodic review of this data can give a good indication of battery per- formance and expected life.

Each battery discharge cycle is put into one of four categories, depending on the length of the event:

•0-30 Seconds Discharge

•31-90 Seconds Discharge

•91-240 Seconds Discharge

•Over 240 Seconds Discharge

Each discharge cycle is sorted by time duration and tagged with the following system parameters:

•System time and date

•Event Number

•Duration of cycle (seconds)

•Lowest DC Bus Voltage

•Highest DC Bus Current

•kW carried by the batteries at the start of cycle

•Battery Environment Ambient Temperature (when equipped with optional temperature sensor)

Up to 132 discharge cycle events can be stored at any given time. When the buffer approaches its capacity, a warning message is broadcast via terminal and modem communication channels and a complete listing of all records (in order of occurrence) is sent to the terminal port. If a serial printer is attached to the terminal port (see 3.2.15 - Communication Interfaces), the operator can print a hard copy of the report. If a printer is not available, a terminal emulation program can capture the report to disk for later review or printing. Once the buffer is filled, new data will replace the old on a first in, first out (FIFO) basis as new cycles occur.

To view this data, select the BATTERY CYCLE MONITOR option on the System Status screen. At the next screen (see Figure 26), you can select either the Battery Cycle Monitoring Summary screen or a screen showing detailed information on any one of the four categories of discharge (0-30 seconds, 31-90 seconds, 91-240 seconds and over 240 seconds).
