Warnings:
DO NOT
exceed the rating on the EMS for any reason. Ho
wever this device is
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 warra
nty, compromise
protection and
could result in
a
possible shock
or fire hazard.
It is important to always check the pedestal power outlet for charring; this
condition means that the source receptacl
e is providing a weak
connection. DO NO
T use it. It could result
in
possible melting of the RV
power plug.
Progressive Industries recommends that you have a certified electrician or an
author
ized dealer perform the installat
ion of the EMS and any future
repairs that may be required.
VIP Enterprises recommends that you use qualified person
nel.When running extension cord
(s)
from the RV to a power source always use
appropriate size cable. Make sure that the cable is rated for outdoor use
to reduce the ris
k of electrical shock. The smaller the cable the higher
resistance and more v
oltage loss, plus it may result
in an electrical fire.
Whenever servicing or installing the EMS, or any other AC power device, make
sure that the power is disconnected from the
source.
RV wiring is different than the wiring found in homes. The neutral and ground
wires are isolated in an RV.
In a home
they are tied together at the
service panel. The reason
,
homes have a bonded ground system and
RVs do not.
Therefore never bon
d the neutral and ground together for
any reason. This will create a ground fault condition and may result in
electrical shock an
d/orfi
re hazard.

Features
High/Low Voltage Protection:
Whenever source power falls below 104 volts, or rises
abo
ve 132 volts the EMS automatically shuts down power to the RV. Once the AC
power source raises 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
Air Conditioner Compressor:
Whenever power is interrupted by the
source or the EMS due to a fault condition, the built in time delay is activated. There
are two settings on the EMS. One is 136 seconds, and the other is 15 seconds.
Consult your air con
ditioner manual to see if it has a time delay built into it. If so use
the 15 second delay if not use the 136 second delay.
Five
mode surge protection:

Surge Indicator:
In the unlikely event a power surge damages the surge protector
circuit within the EMS (L
-
N, or L
-
G) the digital display error code will read E
-
10.
This
is your indication that the surge part of the E
MS
needs to be replaced.
Reverse Polarity Protection:
If source power has reverse polarity the EMS will not
allow power to the RV and the error code will read E1.
Open Neutral Protection:
If the source has an open neutral the display will not light,
and
the EMS will not allow power to the RV.
Open Ground Protection:
If source power has an open ground the EMS will not allow
power to the RV and the error code will read E2.
AC Frequency Protection:
If the source power frequency deviates + or
-
9 hertz from
60 cycles per second the EMS will shut power down and the error code will read E7
or E8.
Accidental 220V Protection:
If 220 volts is detected when plugging into source power
the EMS will not allow power to the RV and the EMS will not be hurt. If this co
ndition
occurs while power is applied to the RV, the EMS shuts off power instantly. In either
case t
he display will read the HHH for high voltage and E3
will be displayed
for the
error
code

Previous E
rror Code (PE):
This feature tells the user why the EMS previously
interrupted power to the RV. This is only displayed if an error actually occurs. PE is
erased from memory when power is disconnected to the EMS.
Bypass:
The enclosed blue jumper wire
al
lows the user to bypass the computer circuit
in the EMS in the event of computer board failure. This allows source power into the
RV. This does not disable the surge protection portion of the EMS.
A
Bypass
Switch
is also available.
Modular Design:
Part
s are designed for simple plug and play replacement, 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

Operating Instructions
1. Plug into source power.
2. The digital display
will read 888 for two seconds then begin scrolling the voltage, amps, line
frequency, and error code. In addition the time delay light will flash (dot in the bottom right
corner). If the dot does not flash a line fault condition is present check error c
ode (see below
or your supplied code card).
3. You may notice when first plugging in that the display may read E
-
9, don’t worry about this, it
only means that the display has not gotten data from the computer yet. By the next cycle
through it should read
E-0 if the source power is normal.
4.
The meter will read L
-
1, and then give you a three digit number that is your line one voltage.
Then 0A, that is line one amps (current). After that L
-
2, a three digit number, that is line two
voltage. Next 0A, whi
ch is line two amps. Amps will read zero until the time delay is
complete. Afterward you will notice a current (amps) reading between 0 and 35. That
number indicates how many amps the RV is drawing on each line. Following, you will notice
a number 60H,
which is your line frequency. That number should remain fairly consistent,
however it may read +/
-
one or two. Last, you will notice the E code, E0 is normal, only if E0
is present will the time delay light flash and the EMS bring power to the RV.
5. V
erify that error code E0 is displayed and set up
is
complete.
Note:
If the wiring reads anything different than correct the EMS will not turn on and we
recommend moving to a different source or use generator power. Also if power is below 104
volts or ab
ove 132 volts the EMS
will not turn on. W
e recommend using generator power.
Important:
The display reads voltages between 78 and 260 volts.
Below will read LLL, above
will read HHH.
Accidental 220 Volt Protection:
Should this condition occur the display
will read HHH instead
of the voltage and the error code will read E
-
4. Power will shut down instantly.
DO NOT
under any circumstances bypass the EMS, otherwise severe damage to the RV will
occur.
Error Code Chart
E-0--Normal condition
E-1--Reve
rse polarity condition (hot and neutral wires reversed)
E-2--Open Ground (no ground wire connection)
E-3--Line 1 Voltage High (line 1 voltage above 132)
E-4--Line 1 Voltage Low (line 1 voltage below 104)
E-5--Line 2 Voltage High (line 2 vol
tage above 132)
E-6--Line 2 Voltage Low (line 2 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)
E-9--Data Link Down (remote display
not getting information)
E-10 Replace the surge protector module
IMPORTANT
N
OTE
:
An open neutral will cause there to be
no
reading on the display
Note: If the EMS cuts the power to the RV it will
show a PE (pre
vious error) code following the E
code.
This denotes the previous error or why the EMS shut down power. Example: The EMS
cut power for low voltage on line 1 then power comes back up and is restored. The error code
reads E0 (good electricity now) but the PE code reads PE4, that tells the use
r low voltage line 1
was the reason the EMS previously cut power.
When power is first applied to the RV you may notice a large current draw on the amp meter even
though little or nothing in the RV is turned on. This is caused by the battery charger built
into the
RV. Less current will be drawn as the batteries become charged. However this may take some
time depending on how low the battery voltage was.

Troubleshooting Guide
Common Installation Mistakes:
1
. Unplug power source, open EMS control b
ox and check connections. Look at
the small wires located under the input connections, and make sure the
conductor colors match (small black wires and black RV input wire, and
small white wires with white RV input wire). If you have wired the input
wires
incorrectly, rewire to match the small wires.
2
. Make sure that input wires are in fact the input wires, connecting the output to
the input of the EMS will result in the device not functioning.
3
. If the EMS is still not functioning at this point follow
instructions below prior to
calling technical support.
Write down the following information prior to calling technical support:
1. Look at the computer board located on the side of the EMS control box. You
will notice a red light, this should be on. I
f the light is not on stop there
and call technical support. If the light is on go to next step.
2. Look at the display, if no reading is present call technical support. If the
display is reading information note the error code message. If the EMS is
r
eading Error 1
-
8 see error code chart on previous page, this means the
EMS is functioning fine. If reading E0, read on.
3. Look to see if the time delay indicator (located in the bottom right number) is
flashing. Wait out time delay. When you see the in
dicator stop flashing
power should come on in the RV. If not
call tech support to install blue
bypass jumper wire.
Power should be on in RV.
Note
;
leaving the unit in
bypass does indeed b
ypass the electrical protection but not the surge
protection.
Tec
hnical support can only help if the above information is provided
.
Therefore please do not call
un
til
the above information is obtained.
To recap
Are the connections right?
Is the red light located on the circuit board inside control box on?
What e
rror code message is being displayed?
Is the delay indicator flashing?
When the bypass
jumper wire is installed
does
power come on in
the RV?
