Error Code Chart
EO Normal Operating Condition.
E1
Reverse Polarity (hot and neutral wires reversed).
E2 Open Ground (no ground wire connection).
E3 Line 1 High Voltage (line voltage above 132V).
E4 Line 1 Low Voltage (line voltage below 104V).
E5*
Line 2 Voltage High (Line voltage above 132).
E6* Line 2 Voltage Low (Line voltage below 104 volts).
E7 Line Frequency High (line frequency above 69 cycles per second).
E8 Line Frequency Low (line frequency below 51 cycles per second).
E9
Data Link Down (call technical support)
E10 Replace Surge protector Module (call technical support).
*Codes only apply to EMS-LCHW50 models.
NOTE:
If the EMS cuts the power to the RV it will show a
PE code following the E code. This denotes the previous
error or why the EMS shut down. Example: The EMS cuts
power for low voltage on Line 1, and then the power is
restored. The Error Code reads E 0, but the PE code
reads PE 4 which tells the user low voltage was the
reason for the EMS previously cutting power. This PE
error code will be deleted when power is disconnected
from the EMS.
NOTE:
There will be a 15 second delay after plugging
the motorhome into shore power while the surge
protector verifies the incoming voltage.
ACCIDENTAL 240 VOLT PROTECTION
Should this condition occur, the display will read 240
volts instead of displaying the voltage and the error code
message will read E3. AC power will shut down instantly.
ᘐ
WARNING
Do not under any circumstances bypass the EMS.
Any bypass will result in severe damage to the
motorhome.
TROUBLESHOOTING GUIDE
In order to help troubleshoot the problem(s) you are
experiencing and render the best possible solution,
it is necessary you be at your motorhome when you
place your call.
1. If the display is illuminated and scrolling information,
note the Error Code. If there is an Error code of 1-9,
the device will interrupt the power. See Error Chart
for definition of AC power problem. The device
being off when an Error Code is present indicates
the product is working properly and protecting
your motorhome.
2. If the display is illuminated and reading Error code E
0, and yet no power is present in the coach, please
contact Technical Support. You must wait for the
time delay light to stop flashing.
3. If the display is not illuminated and power is in the
coach there is a connection issue between the
display and the main control box. Contact a qualified
service center.
Refer to the surge protector manual in the Motorhome
Information Kit for further details.
SOLAR POWER UNIT (OPTIONAL)
Your motorhome may be equipped with a solar power
kit. The solar power unit continuously charges the coach
batteries to maintain the optimal charge, so long as
sunlight is available. The solar controller

is located
in the cabinet above the passenger seat. Refer to the
solar controller manual in the Motorhome Information
Kit for detailed operating instructions.
