The EMS takes 2 minutes 16 seconds (136sec) to supply power.
From page 4 of the PI EMS-PT30X & PT50X manual.
NOTE: If the display indicates an error code other than E 0 or E10, the EMS
will not allow power to the RV. We then recommend moving to a different AC
power source or using your generator. The time delay indication dot will not
be visible if an Error Code E 1 through E 9 is present.
You should report an E 1, E 2, E 3, E 4, E 5 or E 6 Error Code directly to the
Campground Management. Our Tech Support Team will not be able to
assist you if you receive one of these Error Codes.
Contact Progressive Industries Tech Support for an E 7, E 8, E 9 or E10
Error Code.
From page 5 of the manual.
Troubleshooting Guide
In order for the on-call Progressive Industries Technical Support Team
Member to properly diagnose the issue you are experiencing with your
unit and render the best possible solution, it is necessary for you
TO BE AT YOUR RV when you place a Tech Support call.
• If the digital display is illuminated and scrolling through information,
RECORD ALL DATA CODES DISPLAYED. If the digital display indicates
an error code other than E 0 or E10 the EMS will not allow power to
the RV. This indicates a problem with the power and the EMS is working
properly and protecting your RV.
• If the digital display is illuminated, reading an E 0 error code, yet
you have no power in the RV, please contact Progressive Industries Tech
Support. Please remember you must wait the 2 minutes 16 seconds (136
seconds) for the time delay countdown.
• If the digital display is NOT illuminated, but power is present in the coach,
there is a connection issue between the digital display and the main control
module. Please contact Progressive Industries Tech Support.
The Progressive Industries Tech Support Team can only help if the
above information is provided; therefore please do not call until you
have captured this information. Again, it is necessary for you to be at
the RV when you call our Tech Support Team. Thank you.
