|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 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 the AC power is interrupted, or the EMS detects a fault condition, the built-in time delay is activated. There is 136-second (02:16) time delay.
This feature provides full surge protection L-N, L-G, and N-G. Total Joule rating is 1790, 44,000A surge current. Response time of <1 nano second.
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 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 E-1.
If AC power has an open neutral condition, the display will not light, and the EMS will not allow power to the RV.
If AC power has an open ground condition, the EMS will read an error code of E-2 and power will not be allowed to the RV.
If AC power frequency deviates +/- 9 hertz from 60 cycles per second, the EMS will shut down power. An error code of E-7 will be displayed when the frequency is high; and an error code 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.)
Continuously scrolls all of the AC power information, including voltage, current, frequency, error codes and previous errors. Each reading is displayed for two (2) seconds.
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 power is disconnected from the EMS.
Can be exposed to the elements, however, may not be submerged.
The computer is driven by a state-of-the-art microprocessor that is programmed with software to drive the entire EMS.
|Built-In Lock Bracket:
Allows the user to secure the EMS to power source to prevent theft.
