Progressive Industries EMS-HW50C - Manual (Page 9)

Troubleshooting Guide
Common installation mistakes:
1. Check connections. Input is the plug side of the RV and black
should be attached to L1, white to L2 and red to L3. Output
(going to the RV) should match up. T1 is black, T2 white and
T3 is red. The green ground gets attached to the input and output
on the side of the box.
2. Make sure that input wires are, in fact, the input wires.
Connecting the output to the input of the EMS will cause the
device to malfunction.
3. If the EMS is still not functioning at this point, follow
instructions below prior to calling Technical Support.
In order for the on-call Technician to troubleshoot the problem(s) you
are experiencing and render the best possible solution, it is necessary
that you be at your RV 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
coach.
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 Technical Support.
Technical Support can only help if the above information is
provided, therefore, please do not call until this information is
obtained. Again, it is necessary for you to be at the RV when you
place your call. To recap…
1. Are the connections correct?
2. What is the Error Code message being displayed?
3. Is the delay indicator flashing?
