Progressive Industries EMS-LCHW30 - Manual (Page 3)

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
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 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
any circumstances bypass 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.
