Set Test Schedule

The UPS can be setup to perform a routine self-test at intervals you

specify. This will place the UPS into “LINE FAILURE” mode at a specific time
in order to test its functionality and the capacity of the batteries.

Set Test Start (DD:HH:MM = dd:hh:mm)

dd = Days
hh = Hours
mm = Minutes

(i.e., “05:02:15” represents start test in 5 days, 2 hours, 15 minutes).

If the dd, hh and mm are set to 00 then the automatic self-test is inactive

After each self-test the start time is reset to the number of days specified in
the “Set Test Frequency” (menu item 55). This feature requires the USER
SECURITY CODE for activation.

This menu is utilized to set the self test schedule by setting the

count down duration for the start of test. For example, if the user wishes to
set the start of test at midnight and the current time is 6:00 PM, the user can
enter the start of test frequency to (00:06:00) which represents 6 hours.
(NOTE: In the absence of an IID, the CFR does not have a real time clock on
board, and therefore the timing function may drift slightly over a period). The
self-test takes 1 minute to complete.

Set Test Frequency (XXX)

xxx = “off” or “dd days” - dd represents days

The user can activate the auto self-test feature by setting the test

frequency to every “dd” days. The self-test will start at the value displayed in
the “Set Test Start” line in “DD:HH:MM” format.

“OFF” indicates that the automatic self-test function is disabled. It

can be set by entering 0 days for Test Frequency. “dd days” indicates that the
automatic self-test function is enabled and is set to run the self-test at the
interval entered in this field. The maximum value is 30 days; default is “OFF”.
This feature requires the USER SECURITY CODE for activation.

NOTE: If the SID is installed, the TEST LED flashes while the test is in
progress.

Transmit Unsolicited Alarms

This command displays the current settings of the unsolicited alarms

feature. The following text is displayed when this menu is accessed.

56 Transmit Unsolicited Alarms
509 None (xxxx)
510 IPC-XXX (xxxx)
511 Inverter On Alarm Delay (xxxx)

When the CFR receives a

“Start Shutdown” command (menu item 502), it

waits for the period that is specified in the

“Output Shutdown Delay” (menu item 505)

and then shuts down its output. The CFR will remain in the shutdown mode for the time
specified in the

“Output Shutdown Duration” (menu item 506). Depending upon the

setting of the

“Output Shutdown Recovery Mode” (menu item 504) the CFR may restore

output power immediately, even if the input AC line is not present, or may wait for the
input AC line to be restored.
