Use stranded wire for hookup
Solid wire transmits vibration and is more likely to crystallize and break
when subjected to movement.
Separate AC and DC wiring
Never run AC and DC handling wiring together. AC signals can be
coupled into the control circuits leading to erratic operation.
Wire standby battery charger directly to battery
Standby chargers must be wired directly to the battery. Failure to do this
may result in erratic operation due to electronic "noise" coupled into the
microprocessor.
Special precautions for spark ignition engines
Magnetos and ignition coils produce high voltage and cause high
frequency interference. The
EMS PRO LITE Controller is designed to
filter out much of this interference; however, precautions must be taken
to protect the controller. Sender and shutdown wiring must be routed
away from the magneto and spark coil wiring. Resistor spark plugs and
spark plug wires reduce electrical interference and may be required in
especially "noisy" environments. An external relay piloted by the
ECU/Fuel internal relay will be required if the ignition is to be controlled.
Use shielded cable on magnetic pickup
Shielded cable is recommended for connecting the magnetic pickup to the EMS
PRO LITE Controller. This helps prevent signal loss and the possible coupling of
electrical interference into the relatively sensitive speed sensing circuit. Ground
the shield wire on the customer’s end.
NOTE: Proper care during installation will help the EMS PRO
LITE Controller live a long and trouble-free operating life. If for
any reason a question arises during installation, feel free to
call Enovation Controls Technical Support.
Fuses
There is one 10A fuse installed in the controller. It is on the faceplate and
is used for the main power to the panel (Glass SAE type).
