Progressive Industries EMS-PT30C - Manual (Page 2)

Features
High/Low Voltage Protection
Whenever AC power falls below 104 volts, or rises above 132 volts, the EMS
automatically shuts down power to the RV. The EMS will monitor the power and once
the AC power rises above 104 volts, or drops 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 A/C Compressor
If AC power is interrupted, or the EMS detects a fault condition, the built in time
delay is activated. There is a 136-second (02:16) time delay.
3-Mode Surge Protection
This feature provides full surge protection L-N, L-G, and N-G. Total Joule rating is
1790, 44,000A Surge Current. Response time of <1 nano second.
Surge Indicator
In the event of a power surge and the surge protector circuit is damaged within the
EMS, L-N, or L-G, the digital display error code will read E-10. This indicates the
EMS needs to be serviced.
Reverse Polarity Protection
If AC power is a reverse polarity condition, the EMS will not allow power to the RV
and the error code will read E1.
Open Neutral Protection
If AC power has an open neutral condition, the display will not light, and the EMS
will not allow power to the RV.
Open Ground Protection
If AC 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 AC power frequency deviates plus/minus 9 hertz from 60 cycles per second, the
EMS will shut down AC power. An Error Code of E7 will be displayed when the
frequency is high; and an Error Code of E8 will be displayed when frequency is low.
Accidental 240V Protection
If 240 volts is detected when plugging into AC 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. The display will read the voltage and E-3 for the error.
(NEVER BYPASS THE EMS WHEN THIS OCCURS.)
Display
Continuously scrolls all of the AC power information, including voltage, current,
frequency, error codes, and previous errors. Each reading is displayed for two (2)
seconds.
Previous Error Code
This feature tells the user what the previous error was and why power was interrupted
to the RV. To read a Previous Error Code, put a “P” in front of the “E” code. This is
only displayed if an actual error occurs. The error is deleted when the power is
disconnected from the EMS.
Weather Resistant
Can be exposed to elements, however, may not be submerged.
Microprocessor controlled
The computer is driven by a state-of-the-art microprocessor that is programmed with
software to drive the entire EMS.
Built-in Lock Bracket
Allows the user to secure the EMS to power source to prevent theft.
