TRC Surge Guard 35550 Guide De Dépannage

TROUBLESHOOTING GUIDE
50A Hardwire Surge Guard
Surge Guard protects your RV from low quality or incorrect shore power.
Normally shore power should be around 115 –120 Volts AC from L1 or L2 to Neutral, or 240V from L1 to L2. When power
falls too far outside this range it represents a poor or hazardous condition to your RV's electrical system. Surge Guard
provides protection to your RV by turning off power when the line voltages L1 or L2 fall below 102 Volts AC or go above
132 Volts AC.
Surge Guard also protects your electrical system from a Reverse Polarity condition which indicates that the Hot and
Neutral lines of shore power are swapped or reversed. This can be hazardous to equipment and safety. Surge Guard will
not connect power to your RV until the Reverse Polarity fault is corrected.
In the event your Surge Guard is not functioning as expected, perform the following troubleshooting steps in order to
determine and correct any malfunctions. Note: Testing should be performed with AC units and electrical appliances turned
off, then verified with appliances turned on.
Connect the shore power cord to a 240V, 50A power source. The Caution When Flashing Light will blink on and off for
at least 128 seconds before power is connected to the RV. This allows the Surge Guard to correctly determine the Line
Voltages before applying them to the RV. If you also have the Optional Remote LCD Display, the screen will display
"DELAY" plus the delay time for 128 seconds while the Surge Guard is monitoring the incoming power and the caution
light is flashing. Note that this guide also applies if using 120V, 30A power with a suitable adapter.

TROUBLESHOOTING STEPS
The Surge Guard may be operating properly, and you may have a low voltage condition. If so,
turn off as many loads as possible. It is not safe to operate some equipment with low voltage.
Verify that the input voltage L1 and L2 are greater than 102VAC with loads turned on and off.
You have an Under or Over Voltage condition on Line 1 or Line 2 coming into the RV. If these
lights are green, yet you do not have power after 128 seconds on the remote display and the
Caution light remains blinking, then you must inspect your shore power for a Reverse Polarity or
Open conductor fault. These faults will also be visible on the Optional Remote Display if used.
