Error Code Chart
E 0 =
Normal Operating Condition
E 1 = Reverse Polarity (hot and neutral wires reversed)
E 2 =
Open Ground (no ground wire connection)
E 3 =
Line 1 High Voltage (line 1 voltage above 132V)
E 4 =
Line 1 Low Voltage (line 1 voltage below 104V)
E 5*=
Line 2 Voltage High (line 2 voltage above 132V)
E 6*=
Line 2 Voltage Low (line 2 voltage below 104V)
* Codes only apply to EMS-PT50X models

of these Error Codes.
E 7 =

Error Code.
NOTE:
If the EMS shuts down power to the RV it will indicate a PE Code (Previous Error)
following the Error Code. This indicates why the unit shut down. To determine the
meaning of a PE code, ignore the letter P (i.e. PE4 actually indicates an
E 4
Error Code
or Line 1 Low Voltage (line 1 voltage below 104V). See above Error Codes.
Example:
The EMS shuts down power for low voltage on Line-1 and then power is
restored. The Error Code reads
E 0
with a previous error code PE4 indicating low
voltage which is why the unit shut down previously. The PE code will clear when power
is disconnected from the EMS.
