Features
he previous error was and why power was interrupted
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 is a 136-second (02:16) time delay.
3-Mode Surge Protection
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.
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 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 will not allow power 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.)
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 t
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.
Weather Resistant
Can be exposed to elements, however, may not be submerged.
Microprocessor controll ed
The computer is driven by a state-of-the-art microprocessor that is programmed with
software to drive the entire EMS.
Built-in Lo ck Bracket
Allows the user to secure the EMS to power source to prevent theft.
Warnings
• Do not exceed the rating on the EMS for any reason, however
these devices are designed to be reduced down to 120V/15A,
and still maintain full protection.
• Do not modify the EMS in any way, this will void the
warranty, compromise protection, and could result in possible
shock, and/or a fire hazard.
• It is important to always check the pedestal power outlet for
charring; this condition means that the AC receptacle is
providing a weak connection. DO NOT US E! It could result
in possible melting of the RV power plug.
• When running extension cords from the RV to AC power,
always use a 10-gauge cable for your 120 volt, 30 Amp system.
Make sure that the cable is rated for outdoor use to reduce the
risk of electric shock. Small gauge cable will have a higher
resistance and will result in voltage loss, plus it may result in
an electrical fire.
• Whenever servicing or installing the EMS, or any other AC
powered device, make sure AC power is disconnected.
• RV wiring is different than the wiring found in homes; the
neutral and ground conductors are isolated in the RV, unlike in
a home where they are tied together at the service panel. The
reason is: homes have a bonded ground system, whereas RV’s
do not. Therefore, never bond the neutral and ground together
for any reason. This will create a ground fault condition, and
may result in electric shock and/or a fire hazard.
• Never plug the EMS into an inverter.
generator power.
Operating Instructions
1. Plug into AC power.
2. Digital display will read 888 for one second then begin
scrolling the voltage, amps, line frequency, and error
code(s). In addition, the time delay light will flash in the
bottom right corner of the display.
3. The EMS will read a 3-digit number which is your line
voltage. Next, it will give you a “0A” reading. This is the
amp reading; however, it will read zero until the time delay
is complete. Then you will notice a number between 0 and
30. That number indicates how many amps the RV is
drawing. Next, you will notice a number of 60 H which is
your line frequency. That number should remain fairly
consistent, however it may read plus/minus one or two.
Lastly, you will notice the E code; E-0 is normal. Only
when E-0 and E10 is present will the delay light flash and
ultimately bring power to the RV. Refer to your Error
Code Chart that was provided or see the next page for
details.
4. Verify that Error Code E0 is displayed.
5. Set up is complete.
6. The EMS has a 136-second time delay before you will
receive power into your RV.
Important: The display will only read voltages between 78 volts
and 255 volts.
NOTE: If the wiring reads anything different than correct, the
EMS will not turn on and we recommend moving to a different
source of AC power or use your generator power. Also, if power
is below 104 volts or above 132 volts the EMS will not turn on,
and we recommend using your
Error Code Chart
E-0 Normal Condition
E-1 Reverse Polarity Condition (hot and neutral wires reversed)
E-2 Open Ground (means no ground wire connection)
E-3 Line Voltage High (line voltage above 132)
E-4 Line Voltage Low (line voltage below 104)
E-7 Line Frequency High (line frequency above 69 cycles per
second)
E-8 Line Frequency Low (line frequency below 51 cycles per
second)
E10 Replace surge protector module
NOTE: If the EMS cuts the power to the R V, it will show a PE
code following the E code. This denotes the previous error or why
the EMS shut down. Example: The EMS cuts power for low
voltage and then the power is restored. The error code reads EO
but the PE code reads PE4 which tells the user low voltage was
the reason for the E MS previously cutting power. This PE error
code will be deleted when power is disconnected from the EMS.
Accidental 240 Volt protection
Should this condition occur, the display will read 240 volts instead
of displaying the voltage and the error code message will read E-3.
AC power will shut down instantly. DO NOT UNDER ANY
CIRCUMSTANCES BYPASS THE EMS; OTHERWISE,
THIS WILL RESULT IN SEVERE DAMAGE TO THE RV.
Troubleshooting Guide
In order for the on-call Technician to troubleshoot the problem(s)
you are experiencing and render the best possible solution, it is
necessary that you be at your RV when you place your call.
1. If the display is illuminated and scrolling information, note
the Error Code. If there is an Error Code of 1-8, the device
will interrupt the power. See Error Chart for definition of
AC power problem. The device being off when an Error
Code is present indicates the product is working properly
and protecting your coach.
2. If the display is illuminated and reading Error Code E0, and
yet no power is present in the coach, please contact
Technical Support. You must wait 136 seconds for the
time delay light to stop flashing.
3. If the display is not illuminated and there is power is in the
coach, there is a connection issue between the display and
the main control box. Contact Technical Support.
Technical Support can only help if the above information is
provided, therefore, please do not call until this information is
obtained. Again, it is necessary for you to be at the RV when you
place your call.
