High/Low Voltage Protection 
Whenever AC power falls below 104 volts, or rises above 132 volts, the EMS automatically shuts down power to the RV. The EMS will monitor the power and once the AC power rises above 104 volts, or drops below the 132 volt level, the time delay indicator flashes for the preset time and then automatically restores power to the RV. 
Time Delay for A/C Compressor 
If AC power is interrupted, or the EMS detects a fault condition, the built in time delay is activated. There are two settings on the EMS: one is 136 seconds (02:16), and the other is 15 seconds. Consult your air conditioner manual to see if it has a time delay built in. If so, use the 15 second delay, if not; use the 136-second delay. The factory setting is 15 seconds. 
5-Mode Surge Protection 
This feature provides full surge protection L-N, L-N, L-G, L-L and N-G. Total Joule rating is 3,580 and 88,000A surge current. Response time of <1 nano second. 
Surge Indicator 
In the event of a power surge and the surge protector circuit is damaged within the EMS, L-N or L-G, the digital display error code will read E-10. This indicates that the EMS needs to be serviced. 
Reverse Polarity Protection 
If AC power is a reverse polarity condition, the EMS will not allow power to the RV and the error code will read E1. 
Open Neutral Protection
If AC power has an open neutral condition, the display will not light, and the EMS will not allow power to the RV. 
Open Ground Protection 
If AC power has an open ground condition, the EMS will read an error code of E2, and power will not be allowed to the RV. 
AC Frequency Protection 
If AC power frequency deviates plus/minus 9 hertz from 60 cycles per second, the EMS will shut down AC power. An Error Code of E7 will be displayed when the frequency is high; and an Error Code of E8 will be displayed when frequency is low. 
Accidental 240V Protection 
If 240 volts is detected when plugging into AC power, the EMS will NOT allow power to the RV. If this condition occurs while power is applied to the RV, the EMS shuts off power instantly. The display will read the voltage and E-3 for the error. (NEVER BYPASS THE EMS WHEN THIS OCCURS.) 
Integrated Display 
Continuously scrolls the AC power information, including voltage, current, frequency, error codes and previous errors. Each reading is displayed for two (2) seconds. 
Previous Error Code
This feature tells the user what the previous error was and why power was interrupted to the RV. To read a Previous Error Code, put a “P” in front of the “E” code. This is only displayed if an actual error occurs. The error is deleted when the power is disconnected from the EMS. 
Modular Design 
Replacement parts are designed for simple plug and play, making repairs extremely user friendly. 
Microprocessor Controlled 
The computer and remote display are driven by state of the art microprocessors that are programmed with software to drive the entire EMS unit.
