The complete operating and
installation guide for:
EMS-LCHW30
Rated at 120V/30A
Manufactured by:
Progressive Industries
Incorporated
Morrisville, North Carolina

Features:
High low voltage protection: Whenever source power falls below 104 Volts, or
rise above 132 volts the EMS automatically shut down power to the RV. Once the
AC source 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 RV.
Time delay for A/C Compressor: Whenever source 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 you 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
3 Mode surge protection: This feature provides full surge protection L-N, L-G,
and N-G. Total Joule rating is 1780, response time of <1 nano second.
Surge Indicator: If ever a power surge damages the surge protector circuit within
the EMS L-N, or L-G Digital display error code will read E-10. This is your
indication that it needs to be replaced.
Reverse polarity protection: If source 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 the source has an open neutral condition the display
will not light, and will not allow power to the RV.
Open ground protection: If source 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 source power frequency deviants +/- 9 hertz from 60
cycles per second the EMS will shut down source power, and indicate an E7 or E8
error code on the digital display.
Accidental 220V protection: If 220 volts is detected when plugging into source
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. In either case the
display will read HHH for the voltage and E3 for the error code.
Integrated information panel: Scrolls continuously all of the power source
information, voltage, current, frequency, error codes, and previous errors. Each
reading is displayed for 2 seconds
Previous error code: This feature tells the user what the previous error was, and
why power was interrupted to the RV. This is only displayed if an error actually
occurs and goes away when power is disconnected to the EMS.
Bypass : Enclosed blue jumper wire allows the user to bypass the computer circuit
in the EMS in the event of computer failure, thus allowing source power into the
RV. This does not disable the surge protection portion of 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. Should ever this software be changed EMS, owners can receive a free
upgrade processor with the return of the old.
Troubleshooting guide
Common installation mistakes:
1.Check cable connections
Unplug open control box and check connections. Look at
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 matches up with white
RV input wire).
3. 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 to function.
4. 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. Open up control box and look at computer board located on the
side of the control box. You will notice a red light this should be
on, if not stop there and call technical support. If is on go to next
step.
2. Look at display if no reading is present call technical support. If
the display is reading information note the error code message if
the EMS is read Error 1-8 see error code chart on previous page
this means device is functioning fine. If reading E-0 read on.
3. The delay indicator located below the digital read out is flashing
wait out time delay you will see the indicator stop flashing at
which time power should be on in RV. If not call tech support to
install blue bypass jumper wire.
Technical support can only help if the above information is
provided, therefore please do not call till that information is
obtained. To recap
1. Are the connection right?
2. Is the red light on located on circuit board inside control box?
3. What is the Error code message being displayed on the display?
4. Is the delay indicator flashing?

Operation instructions
1. Plug into source power,
2. Digital display will read 888 for 2-seconds then begin scrolling the
voltage, amps, line frequency, and error code. In addition the time delay
light will flash.
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 as not gotten data from
the computer yet. By the next time through it should read E-0 if the source
power is normal.
4. The meter will give you a 3-digit number that 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. Then you will notice a number 60 H that is you line frequency.
That number should remain fairly consistent, however it may read +/- one or
two. Last you will notice the E code, E-0 is normal, only if E-0 is present
will the delay light flash and ultimately bring power to the RV. Refer to your
error code chart card that was provided or see below for details.
5. Verify that error code E0 is displayed
6. 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
p
ower. Also if power is below 104 volts or above 132 volts the EMS will
not turn on, and we recommend using generator power.
Important: The display will only read voltages between 78 volts and 184
volts. If the display drops below 78 the display will read LLL and if the
display goes above 184 the display will read HHH.
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 volts)
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
Accidental 220 Volt protection: Should this condition occur the remote
display will read HHH instead of displaying the voltage, and the Error code
message will read E-4. Power will shut down instantly. Do not under
an
y
circumstances b
y
pass the EMS; otherwise severe
damage to the RV will result.
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 fire hazard.
•It is important to always check the pedestal power outlet
for charring; this condition means that the source
receptacle is providing a weak connection. DO not use, it
could result into a possible melting of RV power plug.
•Progressive Industries recommends you have a certified
electrician or an authorized dealer perform the installation
of the EMS and any future repairs that may be required.
•When running extension cords from the RV to a power
source 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 a will result in a voltage loss,
plus it may result in an electrical fire.
•Whenever servicing or installing the EMS or any other AC
powered device make source power is disconnected from
the source.
•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,
where as 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 fire hazard.

8. Remove control box cover, detach display card and back off four
screws from top of contactor and two ground lugs on side of enclosure.
9. Take the jumper cable with 3 conductor strip, and slide it through the
input side of the EMS control box Then connect black above little black
wires, white above little white wires and green to ground screw0and
tighten each set screw.
11. The cable that came from the transfer switch connects to the out
p
ut
in the same manner except the round sensing coil slides over the black
wire. Make sure that the conductor’s colors match up across from each
other on the contactor.
12. Connect the loose end of the jumper cable to the transfer switch. See
wiring diagram on transfer switch if needed.
13. Double check all connections and make sure they are secure.
14. Secure cable ends by tightening down strain relief’s over outer
jacket. Do not over tighten this could bite through insulation and cause a
short.
15. Set time delay jumper on the circuit board. Factory set is for 15
seconds remove jumper to set for 136 seconds. See features section on
time delay to determine which to use.
16. Re-attach display card with display facing you and digits reading
correctly.
17. Attach EMS lid with the six black machine screws provided, and
attach transfer switch lid.
18. Mount both the control box and remote panel in desired location.
19. Installation is complete. Next, Plug in and follow operation
instructions.
