Display for Normal Operation
During normal operation, the Surge Guard's LCD screen alternates between two displays, a main screen showing voltages and currents for power Lines 1 and 2 coming into the RV; and a secondary screen showing whether power to the RV is ON or OFF, with voltage for Line 1 coming into the RV. The main screen for Model 34850 (50Amp) will show the voltages and currents for Lines 1 and 2, whereas Model 34830 will only show Line 1 since there is no Line 2 for that Model. There are two rows or text lines on the LCD screen. The top row for the main screen shows information for Line 1 in the following format: 120V 50A. This means that the voltage on power Line 1 coming into the RV is at 120 volts and the RV is drawing 50 amps of current on Line 1. The bottom row of the main screen for 34850 shows voltage and current for Line 2.
The top row of the secondary screen for both models shows RV ON or RV OFF, and the bottom row shows the voltage on power Line 1 as L1=120V. If the power coming into the RV is less than 102 volts on either Line 1 or 2, then the main screen will show L1 Low or L2 Low, in place of the voltage or current. If the power coming in is greater than 132 volts, then the main screen will show L1 High or L2 High.
