The first parameter, “O/P Volt Set” is displayed on the LCD (Figure 3.1). 2 Press FUNC to scroll through the parameters until “Battery Test” appears. 3 Press the ENTER button. When the LCD shows “Test?” press ENTER. The test starts and the LCD shows “Battery Test.” 4 After the test, the unit resumes line mode and the LCD shows “Line Mode.” If a fault is found, the FAULT LED is on. Do troubleshooting as described in Section 3.5. Self Test Finished 3.4 Changing the Parameters You can change the unit’s factory set parameters to suit your local conditions (Figure 3.1). Any changes should be done after the unit is started, but before the loads are turned on. Procedure TIP: If no buttons are pushed for 10 seconds, the LCD exits this menu and displays the operating mode. 1 Press the FUNC button for 5 seconds. The first parameter, “O/P Volt Set” is displayed on the LCD. 2 Press FUNC to scroll through the parameters (Figure 3.1). 3 Press ENTER to select a parameter.. Alpha Technologies 3 Operation 18 3.4 Setting the Parameters (Continued) 4 Press FUNC to display the selections. Press ENTER to select the selection. If the LCD shows “Save?” press ENTER to set the unit to the new parameter.

This feature is meant to be used with an external maintenance bypass switch. ** Turn the unit off and restart after changing this parameter. Figure 3.1 Parameters Alpha Technologies 19 3 Operation 3.4 Setting the Parameters (Continued) Notes: 1) HE Mode Set: This is used to set if the unit sends the line power through double conversion and then to the loads (HE Mode:OFF) or straight through to the loads (HE Mode:ON). 2) Set Generator Mode: This widens the input parameters so the unit can be used with a generator. 3) Site Wiring Alarm: This tells you if the line’s ground and neutral wiring is reversed. 4) Free Run Mode, Bypass Enable/Disable at Free Run Mode: These two parameters work together to control the unit’s input voltage or frequency windows. The available combinations are: Combination Result Free Run: ON Bypass: DISABLED (Factory Default) Input window is: 45-65 Hz (Automatic frequency sensing) 96-138 VAC (60 Hz) 184-265 VAC (50 Hz) Free Run: ON Bypass: ENABLED Input voltage window is: ±10%, +10%/-15% or +15/-20% VAC (operator set) Free Run: OFF (Bypass is automatically turned off) Input frequency window is: ±2%, ±5% or ±7% Hz (operator set) Figure 3.2 Free Run/Bypass Combination Table Alpha Technologies 3 Operation 20 3.5 Troubleshooting When the fault LED turns on or the audibile alarm is heard, perform troubleshooting as shown in the table below.
