30 Battery Test Options
Starts the battery test and sets how long the test will run. The default setting for
the test depth-of-discharge is 20%, but this can be adjusted from 0 to 100%. For
a description of the battery test, see BATT TEST in Table B.
31 Inverter On/Off
Switches the inverter on or off to allow you to prevent a damaging deep battery
discharge or to provide backup battery power to the load. For a description, see
INVERTER in
Table B.
You can set a delay before the inverter switches off to allow time for switching off
critical loads. The Set Inverter ON/OFF delay is only available when the Alpha
FXM is in the Battery or Standby modes.
The delay can be adjusted in 1 second steps with a default setting of 0 seconds
to a maximum of 600 seconds (10 minutes). The delay is only available in the
Standby or Battery modes. Once the Alpha FXM returns to the Line mode, the
delay resets itself to 0 seconds.
32 Change Password
Changes the Alpha FXM password. The factory set password is 1111, which can
only be changed when the Alpha FXM is in Line mode. The password is limited
to 4 alpha- numeric characters in length.
34 Line Qualify Time
Let’s you set the delay when the Alpha FXM goes from Battery mode to Line
mode after the line becomes requalified. The purpose of this delay is to make
sure the line is stable before the Alpha FXM switches back to it. For a
description, see QUAL TIME in Table B. The default setting is 3 seconds, but
you can set this to 3, 10, 20, 30, 40 or 50 seconds.
