Progressive Industries EMS-PT30C - Manual (Page 4)

Operating Instructions
1. Plug into AC power.
2. Digital display will read 888 for one second then begin
scrolling the voltage, amps, line frequency, and error
code(s). In addition, the time delay light will flash in the
bottom right corner of the display.
3. The EMS will read a 3-digit number which 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. Next, you will notice a number of 60 H which is
your line frequency. That number should remain fairly
consistent, however it may read plus/minus one or two.
Lastly, you will notice the E code; E-0 is normal. Only
when E-0 and E10 is present will the delay light flash and
ultimately bring power to the RV. Refer to your Error
Code Chart that was provided or see the next page for
details.
4. Verify that Error Code E0 is displayed.
5. Set up is complete.
6. The EMS has a 136-second time delay before you will
receive power into your RV.
Important:
The display will only read voltages between 78 volts
and 255 volts.
NOTE:
If the wiring reads anything different than correct, the
EMS will not turn on and we recommend moving to a different
source of AC power or use your generator power. Also, if power
is below 104 volts or above 132 volts the EMS will not turn on,
and we recommend using your generator power.
