Progressive Industries EMS-HW50C Installation & Operating Manual

Features
High/Low Voltage Protection:
Whenever source power falls below 104 volts, or rises
abo
ve 132 volts the EMS automatically shuts down power to the RV. Once the AC
power source raises above 104 volts or below the 132 volt level the time delay
indicator flashes for the preset time and then automatically restores power to the RV.
Time Delay for
Air Conditioner Compressor:
Whenever 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 your air con
ditioner manual to see if it has a time delay built into it. If so use
the 15 second delay if not use the 136 second delay.

Surge Indicator:
In the unlikely event a power surge damages the surge protector
circuit within the EMS (L
-
N, or L
-
G) the digital display error code will read E
-
10.
This
is your indication that the surge part of the E
MS
needs to be replaced.
Reverse Polarity Protection:
If source power has reverse polarity 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 the display will not light,
and
the EMS will not allow power to the RV.
Open Ground Protection:
If source power has an open ground the EMS will not allow
power to the RV and the error code will read E2.
AC Frequency Protection:
If the source power frequency deviates + or
-
9 hertz from
60 cycles per second the EMS will shut power down and the error code will read E7
or E8.
Accidental 220V Protection:
If 220 volts is detected when plugging into source power
the EMS will not allow power to the RV and the EMS will not be hurt. If this co
ndition
occurs while power is applied to the RV, the EMS shuts off power instantly. In either
case t
he display will read the HHH for high voltage and E3
will be displayed
for the
error
code

Previous E
rror Code (PE):
This feature tells the user why the EMS previously
interrupted power to the RV. This is only displayed if an error actually occurs. PE is
erased from memory when power is disconnected to the EMS.
Bypass:
The enclosed blue jumper wire
al
lows the user to bypass the computer circuit
in the EMS in the event of computer board failure. This allows source power into the
RV. This does not disable the surge protection portion of the EMS.
A
Bypass
Switch
is also available.
Modular Design:
Part
s are designed for simple plug and play replacement, 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 ever be changed EMS owners can receive a free upgraded
processor with return of the old.
