System Status
TheSystem Status screen displays the module TotalOperating Hours and the Battery Cycle Monitor.
BatteryCycle Monitor (Module Only)
Selectingthe Battery Cycle Monitor gives you access to detailedinformation about the module’s most recent
batterydischarge events. Periodic review of thisdata can give a good indication of battery performance and
expectedlife.
Eachbattery discharge cycle is put into one of four categories,depending on the length of the event:
• 0-30Seconds Discharge
• 31-90Seconds Discharge
• 91-240Seconds Discharge
• Over240 Seconds Discharge
Eachdischarge cycle is sorted by time duration and tagged with thefollowing system parameters:
• Systemtime and date
• Event Number
• Durationof cycle (seconds)
• LowestDC Bus Voltage
• HighestDC Bus Current
• kWc arriedby the batteries at the start of cycle
• BatteryEnvironment Ambient Temperature (when equippedwith optional temperature sensor)
Upto 132 discharge cycle events can be stored at any given time. When the buffer approachesits capacity, a
warningmessage is broadcast via terminal andmodem communication channels and a complete listingof all
records(in order of occurrence) is sent to the terminal port. If a serial printeris attached to the terminal port, the
operatorcan print a hard copy of the report. If a printer is not available, a terminalemulation program can cap-
turethe report to disk for later review or printing. Once thebuffer is filled, new data will replace the old on a
FirstIn, First Out basis as new cycles occur.
Toview this data, select the BATTERYCYCLE MONITOR option on the System Statusscreen. At the next
screen (see Figure 26), you can select either the BatteryCycle Monitoring Summary screen or a screen showing
detailedinformation on any one of the four categories of discharge (0-30 seconds,31-90 seconds, 91-240 sec-
ondsand Over 240 seconds).
