Progressive Industries EMS-HW30C - Manual (Page 3)

Operation instructions
1. Plug into source power,
2. Digital display will read 888 for 1-seconds then begin scrolling the voltage, amps,
line frequency, and error code. In addition the time delay light will flash. If delay
light does not flash a fault condition is present look at error code to determine what
the source problem is.
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 power. 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 remote display will only read voltages between 78 volts and 256
volts. If the display drops below 78 the display will read LLL and if the display goes
above 256 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)
E-7 Line Frequency High (line frequency above 69 cycles per second)
E-8 Line frequency Low line frequency below51 cycles per second)
E-9 Data link down (computer not communicating with remote display)
E10 replace surge protector module
NOTE: IF the EMS cuts the Power to the RV it will the show a PE code following the E
code this denotes the previous error or why the EMS shut down. Example: say the EMS
cuts power for low Voltage on line 1 then power is restored. The error code reads EO but
the PE code Reads PE4 that tells the user low Voltage was the reason for the EMS cutting
Power previously
.
Accidental 220 Volt protection: Should this condition occur the remote display will read the
voltage, and the Error code message will read E-4. Power will shut down instantly. Do not
under any circumstances bypass the EMS; otherwise severe damage to the RV will result.
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, as the batteries become
charged the less current the charge will, however this may take some time
depending on how depleted the house batteries are.
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.
• The telephone type cable that connects from the EMS
control box to the remote panel is designed specifically for
the EMS. Therefore do not use store purchased cable,
which will result in the EMS not to function, plus it does
not have the appropriate voltage and current rating for the
application. This could result in possible shock and fire
hazards.
• 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.
