6.4.4 Adjusting and Controlling the Alpha Micro Secure
The Maintenance submenu lets you control the Alpha Micro Secure and change selected items to meet your
operational needs.
Procedure
From the Main menu, type 3 and press Enter.
Table H — Maintenance Submenu
30 Battery Test Options This starts the battery test and sets how long the test will run. The default setting for the
test duration is 2 minutes, but this can be adjusted in 1 minute intervals. See "Operating
the Alpha Micro Secure, BATT TEST”.
31 Inverter On/Off This 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. See “Operating the
Alpha Micro Secure INVERTER”.
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 Micro Secure 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 Micro Secure returns to the Line mode, the delay resets
itself to 0 seconds.
32 Change Password This changes the Alpha Micro Secure’s password. The factory set password is 1111,
which can only be changed when the Alpha Micro Secure is in Line mode. The password
is limited to 4 alpha-numeric characters in length.
34 Line Qualify Time This lets you set the delay when the Alpha Micro Secure 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 Micro Secure switches back to it. See “Operating the
Alpha Micro Secure, QUAL TIME”.
The default setting is 3 seconds, but you can set this to 3, 10, 20, 30, 40 or 50 seconds.
35 Low Battery Warning
Voltage
The lets you set the Alpha Micro Secure’s low battery warning voltage, adjusting the
setting to match the batteries you are using and the actual operating conditions.
The default value is 40% (47 Vdc) and can be adjusted in 1% (0.05 Vdc) increments
between 45.0 (0 %) and 50.0 Vdc (100%) by typing in the % battery voltage level where
you want the warning to be triggered.
36 Load Shed Timer On/Off This lets you switch the timer contacts on or off. See "Contacts C1 to C6”.
