Progressive Industries EMS-HW30C - Manual (Page 2)

Features:
High low voltage protection: Whenever source power falls below 104 Volts, or
rise above 132 volts the EMS automatically shut down power to the RV. Once the
AC source rises above 104-volts, or below the 132-volt level the time delay
indicator flashes for the preset time and then automatically restores power to RV.
Time delay for A/C Compressor:
Whenever source power is interrupted by the
source or the EMS, due to a fault condition the built in time delay is activated.
There are two settings on the EMS; one is 136 seconds, and the other is 15 seconds.
Consult you Air conditioner manual to see if it has a time delay built in, if so use
the 15-second delay if not use the 136-second delay.
3 Mode surge protection:
This feature provides full surge protection L-N, L-G,
and N-G. Total Joule rating is 1780, response time of <1 nano second.
Surge Indicator:
If ever a power surge damages the surge protector circuit within
the EMS L-N, or L-G Digital display error code will read E-10. This is your
indication that it needs to be replaced.
Reverse polarity protection:
If source has a reverse polarity condition, the EMS
will not allow power to the RV and the error code will read E1.
Open neutral protection:
If the source has an open neutral condition the display
will not light, and will not allow power to the RV.
Open ground protection:
If source power has an open ground condition the EMS
will read an error code of E2 and will not allow power to the RV.
AC Frequency Protection:
If source power frequency deviants +/- 9 hertz from 60
cycles per second the EMS will shut down source power, and indicate an E7 or E8
error code on the digital display.
Accidental 220V protection:
If 220 volts is detected when plugging into source
power the EMS will not allow power to the RV. If this condition occurs while
power is applied to the RV, the EMS shuts off power instantly. In either case the
display will read the voltage and E-4 for the error code.
Remote information panel
: Scrolls continuously all of the power source
information, voltage, current, frequency, error codes, and previous errors. Each
reading is displayed for 2 seconds
Previous error code:
This feature tells the user why the EMS previously
interrupted power to the RV. This is only displayed if an error actually occurs, and
goes away when power is disconnected to the EMS.
Bypass switch:
This switch is located on the remote panel, and allows the user to
bypass the computer circuit in the EMS in the event of computer failure, thus
allowing source power into the RV. This does not disable the surge protection
portion of the EMS.
Modular design
Replacement parts are designed for simple plug and play, making
repairs extremely user friendly.
Microprocessor controlled:
The computer, and remote display are driven by state
of the art microprocessors that are programmed with software to drive the entire
EMS. Should this software be changed EMS, owners can receive a free upgrade
processor with the return of the old.
Troubleshooting guide
Common installation mistakes:
1. Check remote cable connections by unplugging and re-plugging
make sure you hear a click to insure a good connection.
2. Unplug open control box and check connections. Look at small
wires located under the input connections, and make sure the
conductor colors match (small black wires and black RV input
wire, and small white wires matches up with white RV input wire).
3. Make sure that input wires are in fact the input wires,
connecting the output to the input of the EMS will result in the
device not to function.
4. If the EMS is still not functioning at this point follow instruction
below prior to calling technical support.
Write down the following information prior to calling
technical support:
1. Open up control box and look at computer board located on the
side of the control box. You will notice a red light this should be
on, if not stop there and call technical support. If is on go to next
step.
2. Look at remote display if no reading is present call technical
support. If the display is reading information note the error code
message if the EMS is read Error 1-8 see error code chart on
previous page this means device is functioning fine. If however it
is reading E-9 call technical support, if reading E-0 read on.
3. The delay indicator located below the digital read out is flashing
wait out time delay you see the indicator stop flashing at which
time power should be on in RV. If not there is a bypass switch
located on the remote panel push up till the display reads off. You
should have power to the RV. If not call technical support.
Technical support can only help if the above information is
provided, therefore please do not call till that information is
obtained. To recap
1. Are the connections right?
2. Is the red light on located on circuit board inside control box?
3. What is the Error code message being displayed on the remote
panel?
4. Is the delay indicator flashing?
5. When the bypass switch is in the off position does power come
on in the RV?
