306 How to Read the Alarm and Inverter Logs
Your FERRUPS makes an entry in its logs every time it sounds an alarm or switches to inverter (battery power).
This information can be helpful in diagnosing problems.
You can view the Alarm and Inverter Logs from either a FERRUPS control panel or a terminal or computer that
you have connected to the RS232 port. (See Section 400 to connect FERRUPS to a terminal or computer.)
Reading Logs from a Control Panel
Alarm Log:
The Alarm Log is parameter 25. To display the Alarm Log from a control panel, follow these steps:
PRESS THIS KEY:
DISPLAY SHOWS:
[DISPLAY] Display:
[2][5] Display: 25
[ENTER] 25 Alarm Log
The display will then scroll through the 20 most recent entries in the Alarm Log. If you have not had 20 alarm
conditions, the display will scroll through the entries FERRUPS has recorded. You can use the number keys as
you view this scrolling display:

TO DO THIS:
[0] Pause the scrolling and start it again.
[1] through [9] Go to the next log entry.
Each log entry consists of four pieces of information: the alarm code, the date (month/day) of the alarm, the time
(in 24-hour time) and the duration (in hours and minutes).
For instance, one entry might look like this:
B 0205 1017 0005
In this example, “B” means the alarm was “Near Low Battery” (see Section 304 for more information on alarm
codes); if alarm B was active, there would be an asterisk (*) after “B.” “0205" means the alarm occurred on
February 5 (2/5). “1017” means the alarm occurred at 10:17 a.m. “0005” means the alarm condition lasted for 0
hours and 5 minutes.

The Inverter Log is parameter 24. To display the Inverter Log, follow these steps:
PRESS THIS KEY:
DISPLAY SHOWS:

times, the display will scroll through the entries FERRUPS has recorded. You can use the number keys as you
view this scrolling display:
