SEARCH MODE WATTS Potentiometer
The Search Mode Watts potentiometer adjusts the current threshold required to
bring the inverter out of search mode into full wave operation. With search mode
enabled, the inverter pulses the AC output looking for an applied load. With no
load detected, the inverter goes into the search mode to minimize energy
consumption. When a load is applied, the load current is sensed, bringing the
inverter into full power operation. Disabling the threshold (setting the
potentiometer fully CCW) causes the inverter to remain ON (in full power
operation) regardless of an applied load.
To set the Search Mode Watts:
1. Remove the AC input source from the inverter. The inverter switches to
battery operation. Ensure all inverter supported appliances are switched OFF.
2. Turn the potentiometer completely CW (to MAX).
3. Switch on the load which will trigger the inverter to full power. This could be
a lamp located in a convenient location if the power goes out. The light may
flicker as the inverter searches the line for a load. The green INVERTER
MODE LED blinks 2-3 times a second, indicating the inverter is in the
SEARCH MODE.
4. Slowly turn the potentiometer CCW (toward MIN) when the proper setting is
found, the lamp and INVERTER MODE LED will light steady.
5. Turn the lamp OFF for a moment. The inverter should switch back to the
SEARCH MODE. Turn the lamp ON. Ensure the inverter comes out of the
Search Mode. Adjust the potentiometer up or down as necessary.
Important:
1. Switch positions “0” and “1” are for monthly battery maintenance only.
Return the switch to the appropriate position for the system’s batteries when
Equalize charging has completed. NEVER EQUALIZE GEL BATTERIES!
Use together with BATTERY CHARGER RATE potentiometer (position1) or
BATTERY CAPACITY potentiometer (position 0).
2. Equalize voltages are displayed in the table with an asterisk (*) - Switch
positions “0” and “1” only.
3. Switch position “7” is the default values as shipped from the factory.
4. Always refer to the battery manufacturer’s specifications for equalization.
Important:
The Search Mode only activates when the unit is operating in the inverter
mode (from batteries) to prevent unnecessary battery discharge when electrical power is
not required. If the inverter is supporting loads that must constantly be powered, turn the
search mode OFF by setting the potentiometer fully CCW to the DEFEAT position.
