Electrical Systems
MINI-EMS OPERATION
Press the SELECT button on the Mini-EMS control panel to
choose the electrical service listed below:
30A (
30-amp service
)
– the power control system (PCS)
senses 0-volts AC between L1 and L2. The I/O Module has
a current sensor which monitors the current on the neutral
wire. When the current exceeds the 30-amp limit, because
possibly the owner has turned on the microwave, the PCS will
limit the current by shedding appliances. Once the total RV
current has dropped, for example because an owner oper-
ated appliance has been turned off, the PCS will reverse the
previous procedure, returning power to appliances whose
operation is not immediately critical.
20A (
20-amp service
)
– the PCS senses 0-volts AC be-
tween L1 and L2, and the owner selects 20A on the remote
display. The PCS performs the same functions as described
above, except that it limits total current to 20-amps.
GEN (generator)
– the PCS senses power to the generator
hour meter. In this mode, the PCS assumes enough power is
available and goes to sleep. It displays the fact that the gen-
set (generator set) is running, and that all loads are powered.
50A ( 50-amp service ) – the PCS senses 240-volt AC be-
tween L1 and L2 to determine this mode of operation. In this
mode the PCS assumes enough power is available and goes
to sleep. It displays the fact that 50-amp service is available
and that all loads are powered.
For example:
If you turn on additional appliances such as a micro-
wave, coffee pot or hair dryer, the Mini-PCS can shed
two 120-volt AC appliances such as the refrigerator
and water heater, then if additional reduction in power
is required the second air conditioner and lastly the
first air conditioner is shed. As appliances are turned
ON, the Mini-EMS will automatically turn power back
on to each of the shed loads in reverse sequence.
