Energy Management System; Energy Management - Monaco DIPLOMAT 2004 Owner's Manual

The Energy Management System is easily identified by the remote
display panel located inside motorhome.
The 50 Amp Smart EMS consists of two elements: the display panel and
the bedroom distribution panel. The distribution panel, located in the
bedroom, is a completely self-contained 120/240 Volt power distribution and
energy management system intended to be used in recreational vehicles. It is
housed in a sheet metal enclosure with removable front panel. It provides
circuit protection for all the 120 Volt AC loads in the motorhome and a system
of energy management to minimize the over-loading and tripping of circuit
breakers.
Circuit Breakers: The distribution panel offers slots for eight single or
dual, standard 120 Volt circuit breakers. Two of these breakers, located in the
two center positions, must be a 50 Amp unit that act as a main input protection
for each of the lines supplying the remainder of the branch breakers (up to 12).
Energy Management: The 50 Amp Smart EMS automatically senses the
available power to the motorhome, determining whether it is connected to a 120
Volt AC - 30 Amp shore power source, 50 Amp shore power source or generator
source. Depending upon available power, the EMS controls the operation of 6
possible loads as indicated on the distribution panel. These may be any type
load, but are typically heavier loads; those whose use can be "postponed until a
time when current is available for use. If the available power source is 120 Volt
AC - 30 Amp shore power, the EMS attempts to keep the total 120 Volt current
draw to less than 30 Amps.
Operation: If 120 Volt AC is not available at the distribution panel, L1 or
L2 outputs, the system shuts itself off. This feature is intended to prevent the
system from drawing current from the +12 Volt DC battery supply when not in
operation.
When 120 Volt AC power is applied, the system automatically powers up and
determines the nature of the power source.
If the generator is running, 120 Volt AC will be present at the distribution
panel L1 and L2 inputs. In this mode the energy management feature is disabled
and all control relay contacts are closed, energizing all of the controlled loads.
The control module sends a signal to the display panel causing the load meter to
display actual load current, the GEN SET service indicator to light and all power
status indicators to light.
