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 Figure 2.
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
Figure 2.
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
Inverter 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
Lets you set the delay when the Alpha FXM goes from Inverter mode to Line mode after
the line becomes re-qualified. The purpose of this delay is to make sure the line is stable
before the Alpha FXM switches back to it. The default setting is 3 seconds, but user
adjustable in increments of 1 sec until 1 minute, and then in increments of 1 minute to 15
minutes max.
35 Low Battery Warning
Voltage
Lets you set the Alpha FXM low battery warning voltage by typing in the % battery
voltage level where you want the warning to be triggered. Adjust the setting to match the
batteries you are using and the actual operating conditions.
