Features
High/Low Voltage Protection |
Whenever AC power lowers
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 are two settings on the EMS: one is 136 seconds
(02:16), and the other is 15 seconds. Consult your 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-seconds delay. The factory
setting is 15 seconds.
3-Mode Surge Protection (EMS-HW30C) |
This feature
provides full surge protection L-N, L-G, and N-G. Total Joule
rating is 1,790J and 44,000A surge current. Response time <1
Nano second.
5-Mode Surge Protection (EMS-HW50C) |
This feature provides
full surge protection L-N, L-N, L-G, L-L, and N-G. Joule rating is
3,580J and 88,000A surge current. Response time <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 error code will read E10. This indicates the EMS needs to
be serviced.
Reverse Polarity Protection |
If AC power has a reverse polarity
condition, the EMS will not allow power to the RV and the error
code will read E 1
Open Neutral Protection |
If AC power has an open neutral, the display will not light and the
EMS will not allow power to the RV.
