Q. MY UNIT ISN’T BOOSTING
First determine: Is the park voltage over 118 Volts?
Check the park power. The unit is in by-pass over 115+1v volts. It will boost when the park power drops below 116 volts. Your Hughes Autoformer gets its instructions to boost or by-pass from the park power only. It does not read or recognize the reading in your RV. If the park power is inferior (reading below 95), the Autoformer will not have enough power to work and will go into by-pass mode (and will not boost). In this case, your unit may have absorbed an electrical surge or spike. The Autoformer is designed to absorb the damage in order to save your other appliances. If this is the problem, please return it to us for service. (Remember, freight charges will apply.) Electrical surges or spikes can occur at any time and are rarely noticed by the human eye. The cause of a spike or surge could be a power outage in a shopping center miles away. Sundays are typically day for surges/spikes to occur because campers are unplugging their RV’s to leave the park. Please check the cord for damage and also check for a bad (loose) park receptacle if the prongs are red.
Q. THE UNIT BOOSTS ALL THE TIME.
Is the RV Park voltage under 116 Volts? Check the park power. The unit boosts at 116 volts and will go to by-pass at 118 volts. If the Autoformer is boosting when the park voltage is over 118 volts, return it to us for service. (Freight charges will apply.)
Q. WHAT DOES THE CLICKING SOUND MEAN?
The Autoformer is switching, or preparing to switch, to boost or by-pass. This is a normal occurrence.
Q. WHY IS THE VOLTAGE IN MY RV LOWER THAN THE VOLTAGE MEASURED AT THE POWER POLE?
In most RV’s, the voltage to an outlet (plug) will depend on the load (number of items plugged in), and the length of wire from the panel to the plug (line loss). If you measure the voltage in the coach on the same circuit that a heater or coffee pot is plugged into, you will get a lower reading due to voltage loss in the wire. The reading will not be the voltage to the RV, rather, it will be the reading of the circuit your meter is plugged into.
Q. WILL A COFFEE POT OR HEATER PULL DOWN THE PARK VOLTAGE?
Yes, but your RV will drop more than the park. The park may drop one or two volts while the voltage inside the RV at the meter may drop several volts if the meter is on the same line as the heater or appliance. This may or may not drop the park enough to cause boost.
Q. WHAT DO THE LIGHTS ON MY AUTOFORMER INDICATE?
This light will turn on when you plug the Autoformer into the park power only if the park power is safe to use. If the amber light does not stay on, do not plug your rig’s service cord into the Autoformer. Instead, use a different park power pole and report the questionable power pole to the park manager.
The 30AMP model has one red light. The 50AMP model has two; one for each power lead. Each time the Autoformer is powered up, there will be a three to five second delay while the average incoming voltage is evaluated. Then, if the park voltage is low, the red light(s) will illuminate indicating the unit is boosting.
All plug-in analog meters are only accurate within 2 to 4 volts while digital multi-meters are much more accurate. For this reason, we recommend to not rely on a plug-in meter!
