Error Code Chart - Progressive Industries EMS-PT50 series Instruction Manual

INSTRUCTION MANUAL: ELECTRICAL MANAGEMENT SYSTEM (EMS)

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
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.
E 7 = Line Frequency High (line frequency above 69 Hz)
E 8 = Line Frequency Low (line frequency below 51 Hz)
E 9 = Data Link Down (does not apply to EMS-PT models)
E 10 = Replace Surge Protector Module (call technical support)
Contact Progressive Industries Tech Support for an E 7, E 8, E 9 or E 10 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.
