Surge
Protector with Voltage ProtectioN and Remote Display.Hardwired for
50amp RV's. 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 are tow 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, 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 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. 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 E-2 and power will not be allowed to the RV,. AC Frequency
Protection: 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.)
Remote Display: 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. 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 power is disconnected from the EMS.
Bypass: This switch is located on the remote panel, and allows the user
to bypass the computer circuit in the EMS in the event of computer
failure, thus allowing AC power into the RV. This does not disable the
surge protection portion of the EMS; however, all other features are
disabled. Modular Design: Replacement parts are designed for simple
plug and play, making repairs extremely user friendly. Microprocessor
Controlled: The computer is driven by a state-of-the-art microprocessor
that is programmed with software to drive the entire EMS.
