HOW IT WORKS
ENERGY MANAGEMENT
The main neutral line is routed through the magnetically coupled current sensor. This sensor measures the
current flowing through the neutral line, which is the total amount being drawn by all the 120 volt appliances in
the RV. When this current exceeds 30 Amps (20 Amps if the threshold has been set lower), the
2004 EMS
service.
CONTROLLED LOADS
The system offers control of up to four powered loads. Loads that are to be controlled are connected to one of
the relay circuits of the . There are a total of four control relays in the . Two of these relays (relay 1
rated at 20 Amps & relay 2 rated at 10 Amps), are relays with normally-closed contacts used to interrupt the 120
volt power to the loads. These circuits are intended to control 120 volt appliances such as refrigerator, water
heater, washer/dryer, coffee maker, etc. For the 120 VAC switched loads, power is routed from the individual
branch circuit breakers to one of these 120 VAC relays. The controlled load is then fed from that relay.
The remainder of the relays, relays 3 and 4, are intended to switch low voltage loads. Relay 3 is a single- pole,
double-throw relay with all contacts available. Relay 4 is a single-pole double-throw relay with only the common and
normally-closed contacts available. These are intended to control air conditioners or other appliances equipped
with low voltage controls or thermostats. The contacts of the relays are typically wired in series with the low voltage
controls or thermostats of air conditioners so the turns off only the compressor, or the compressor and fan.
These circuits couldalso control other120 volt appliances if an additional control relay is addedexternally.

Powerline 2004 EMS Control Module
Control) System as the communications link between the l and the As an additional
diagnostic feature, the system includes two Communication Status LED’s on the Control Module. In normal
operation, when the is configured in the Stand-Alone Mode, or as the RV Multiplex system, the
green “IPX OK”LED should belit and the red “IPX Fail” LEDshould not belit.
Utilizing the RV Multiplex/PMCsystem, the SmartEMS System can:
1) Operate as a Stand-Alone system.
2) Operate as a RV Multiplex Systemmaster in aRV Multiplex System allowing other devicessuch as
inverter/converters, input andoutput modules, andswitch panels, to communicate with each other and the
Smart EMS System.
3) Operate as a PMC Transceiver with the additionof a PMCCentral Processing Unit(CPU).

INSTALLATION AND SERVICE MANUAL
OPERATION WHEN CONNECTED TO 240VAC, 50 AMP SERVICE:
If 240 VAC, 50 Amp service is present at the L1, L2 and neutral inputs, the energy management feature is disabled
and the Control Module sends a signal to the Display Module which causes the load meter to go blank, the 50 AMP
service indicator tolight, and allpower status indicators to light.
OPERATION WHENTHE GENERATOR IS RUNNING:
If the generator is running, 120 VAC will be present at the L1 or L2, and neutral inputs and a +12 VDC signal will be
present at J3 pin 8 on the Control Module. In this mode the energy management feature is disabled and the Control
Module sends a signal to the Display Module which causes the load meter to display actual load current, the GEN
SET service indicator to light, and allpower status indicatorsto light.
OPERATION WHEN CONNECTED TO 120VAC, 30 AMP SERVICE:
If 120 VAC is present at the L1, or L2 and neutral inputs and no +12 VDC signal is present at J3, pin 8 on the Control
Module the will assume that 120 VAC, 30 Amp shore power is available and the energy management feature
will be enabled. The Control Module sends a signal to the Display Module, which causes the load meter to display
actual load current and the 30 Amp service indicator to light. The power status indicators will light when power is
available to runits corresponding load.
EMS
Initially, all relay contacts are closed. The total current is monitored. If the total current should exceed the service
limit, the system will turn off the first load in the shedding table. As it does this, it calculates the amount of current that
was removed, which is the value for that load. This value is placed in memory. If the current remains above the
service limit, the system will turn off the next load in the shedding table. Again, it calculates the amount of current that
was removed and places this value, which is the value for that load, in memory. In like manner the system turns off
loads until the total current falls below the service limit or all of the four controlled loads have been shed. In this
process the system has "learned" the amount of current that each particular load draws. This feature compensates
for the differences in current draw over a range of line voltage and ambient temperature, by re-learning the load each
time it isturned off or "shed".
The system now waits until the total current is lower than the service limit and enough current is available, as
compared with the amount in memory for the last load shed, before it will turn that load back on. This assures that
there is sufficient currentto operate theload.
There is a two minute minimum delay period after a load is shed before the load will be turned back on again to
prevent air conditionersfrom turning onwith a head of pressure.

INSTALLATION AND SERVICE MANUAL
DISPLAY PANEL
The Display Panel can be mounted remotely and connects to the Control Module with a small gauge, three wire
cable.
Four Power Status LED's indicate whether power is applied to those loads. These LED's are on when the power is
applied.
A two digit display, the Load Meter, indicates the amount of current actually being drawn by all the appliances in the
coach.
The Service Select button allows the current threshold to be changed between 30 Amps or 20 Amps, to match the
incoming service. When 120 VAC power is first applied, the system will always be in the 30 Amp mode. Momentarily
pressing this buttonwill switch thesystem to the 20 Amp mode.
Four Service Type LED's indicate the type of service that the system is operating under. If the GEN SET service
indicator is lit, the system has automatically detected the presence of 120 VAC at the L1 and L2 inputs and the
presence of the +12 VDC run signal from the generator at the GEN SET input on the Control Module. If the 50 AMP
service indicator is lit, the system has automatically detected the presence of 240 VAC at the L1 and L2 inputs on the
control module. If the 30 AMP service indicator is lit, the system has automatically detected the presence of 120 VAC
at the L1 and L2 inputs and the absence of the +12 VDC run signal from the generator input on the Control Module. If
the 20 AMP service indicator is lit, the user has selected that mode by momentarily pressing the 20/30 Amp select
button. Momentarily pressing this button again will switchthe system backto the 30 Amp mode.
This panel can also be used to display the value of current stored in memory for each of the four loads. Pressing and
holding the 30/20Amp Select button for 3 seconds, will cause the top power status indicator to light. The load meter
will only displaythe "learned" current(not the present current) for that load.
Subsequent presses of the button will step the display down through each individual power status indicator and
display the "learned" current for that particular load. NOTE: If a load has not been shed, the system will not have had
a chance to learn the current and the default value of zero (0) will display. After a short period of no activity, the
display will automaticallyreturn to normaloperation.

The EMS Control Module is installed inside the main distribution panel. The metal mounting bracket should be
placed as shownand the singlescrew mounting the breaker panel should be removedand replaced asshown.
The wiring to the box should be routed through the holes in the back and secured using approved cable connectors.
The wires shouldbe copper conductors with the appropriatesize and insulation to meet N.E.C. code.
ONLY,
The main White or "neutral" lead should be routed through the hole in the current sensor and then to the screw
terminal on theNeutral Bar.
To connect the 120 volt controlled loads, jumper wires should be connected from the respective circuit breakers to
the associated screw terminals on the EMS Control Module. The black wires to the controlled loads should be
connected to the proper screw terminals on the EMS Control Module. Be sure these wires are under the screw
terminals and thatthey are tight.

The 12 VDC voltage connections are made through the 8 pin Mate-N-Lok plug on the low voltage side of the
Control Module. The connections are as follows:

3 Relay 3 Normally Open
4 Relay 3 Common
5 Relay 3 Normally Closed
6 Relay 4 Common
7 Relay 4 Normally Closed
8 Gen. Set Run +12 VDC Input
The +12 volts should be supplied from a source fused at 5 Amps minimum and capable of delivering up to 1 Amp of
AVERAGE current. Protecting this connection with a higher rated fuse is acceptable since the EMS is internally
protected with 5 Amp fuse. The low voltage wires are brought into the box through the large hole in the lower lefthand corner ofthe back ofthe box.
The Relay 3 connections are typically made to the low voltage compressor control wires of the air conditioners. The
normally closed contacts are wired in "series" with the compressor control lead. This means that the compressor
control wire is cut and the two ends are wired to the Common and the Normally Closed contacts of Relay 3. In this
way, the EMS can interrupt the operation of the compressor, just as the thermostat does. The Relay 4 connections
are typically made to the thermostat wires of the air conditioners. The normally closed contacts are wired in "series"
with the thermostat. This means that the thermostat wire is cut and the two ends are wired to the Common and the
Normally Closed contacts of Relay 4. In this way, the EMS can interrupt the operation of the fan, just as the
thermostat does.

Route the harness from the hole for the Display Panel to the EMS Control Module (up to 40 feet of cable is
acceptable). Plug the cable into the EMS Control Module, assuring it is properly seated on all four pins. (Note: This
cable is polarized, the latches of each end of the connector mate to each other, and will go on easily in the right
direction.)
The Remote Panel should be plugged onto the harness observing the polarity as before. The panel should then be
installed in the hole and screwed in place using two # 6, flat head screws through the holes in the panel. The white
function label should be lettered to correspond to the order of load shedding and installed. The cover label should be
placed against thefront panel inthe trim bezel snapped on to hold the label inplace.
PERFORMANCE TEST
The system is now ready for testing.
At the installers preference, to assure there are no potential shorts, a Hi-Pot test can be performed on the installation.
The Hi-Pot testshould be conductedin accordance with standard procedures for the testerbeing used.
SYSTEM TEST
Initially, all the 120 volt loads should be turned off or disconnected. Both 120 volt AC and 12 volt DC power should
now be applied to the system. Referring to the Display Panel, the numeric display should read "0" and the four load
LED's should come on. A clamp-on type ammeter may be used to measure the current being supplied by the 30 Amp
shore power cord.
(continued)
Connect or turn on one of the controlled AC loads. It should operate and the numeric display or the clamp-on
ammeter should show the amount of current that load is drawn. Turn that appliance off and repeat this with each of
the others.
To test the load shedding, turn on all the controlled appliances. The total current drawn should exceed 30 Amps. (If
not - add additional loads to the non-controlled receptacles.) When the total amount of current exceeds 30 Amps,
the loads shouldbegin to turnoff to bring the total below30Amps.
While connected to 30 Amp service, press the 30/20 Amp Select buttton and watch the system toggle between 30
Amp and 20Amp service.
Plug the systemto 50 Amp service. The 50Amp service indicator should light.
Start the Generator. The GenSet service indicator should light.
