Powerware FSS-0342J - Manual (Page 24)

Page 21
Each entry includes four pieces of information: the inverter code, the date (month/day) of the inverter run, the
time (in 24-hour time) and the duration (in hours and minutes). For instance, one entry might look like this:
L 0205 0951 0015
In this example, “L” means the FERRUPS went to inverter because it lost AC input power; if the inverter was
still running, there would be an asterisk (*) after the “L.” “0205” means the inverter ran on February 5 (2/5).
“0951” means the inverter ran at 9:51 a.m. “0015” means the inverter ran for 0 hours and 15 minutes.
Here’s how to interpret the inverter codes:
Inverter Code Meaning Explanation
T System Test FERRUPS went to inverter to test the batteries.
B Brownout AC input voltage was too low.
L Line Loss AC input power was lost.
M Manual The inverter was started manually.
F Frequency Input frequency was too high or too low.
R Reset A system reset was performed.
Reading Logs from a Terminal or Computer
You can also read the logs from a terminal or computer that is connected to FERRUPS’ RS232 port.
Alarm Log: To display the Alarm Log on a terminal or computer, you can use the alarmlog or logs command.
(See
Section 402 . The Logs command displays both the Alarm and Inverter Logs.) These commands will display
up to 20 log entries in a table. For example, the log might look like the table below:
Active EventDate EventTime Duration Code/Event
No 08/25/1993 11:25:32 00:00:45 J-User Test Alarm
No 08/24/1993 12:13:18 00:01:08 A-Low Battery
No 08/24/1993 12:05:07 00:08:11 B-Near Low Battery
The table shows whether the alarm is active now (Active), the date and time of each alarm, how long it lasted
(Duration), and what caused the alarm (Code/Event).
You can also display parameter 25 to view the Alarm Log; this display is the same as the control panel display.
Inverter Log: To display the Inverter Log on a terminal or computer, you can use the inverterlog or logs
command. (See
Section 402 . The logs command displays both the Alarm and Inverter Logs.) These commands
will display up to 20 log entries in a table. For example, the log might look like this:
Active EventDate EventTime Duration Code/Event
No 08/25/1993 11:25:32 00:00:45 M-Manual turnon
No 08/24/1993 12:13:18 00:01:08 L-Line fault
The table shows whether FERRUPS is running on inverter (battery power) now (Active), the date and time that
FERRUPS ran on battery power, the length of time FERRUPS ran on battery power (Duration), and the reason
(Code/Event).
You can also display parameter 24 to view the Inverter Log; this display will be the same as the control panel
display.
