Installation Variation #3: For vessels using a keypad, or digital switching for engine starting.
Also used for boats with multiple engines not using the DPST installation method.
For use with MKSMXXX01 Models
NOTE:
The PLC inside the MKSM needs power (approximately 2.5 amps) from a source, such
as a key switch, that provides power only when the boat is in operation. Consider this
additional 2.5 amps of power and how it may affect the reliability of the source. This
new circuit should be protected with a 5-amp fuse or circuit breaker per ABYC
standards, and it should in no way affect the integrity of the engine’s starting or running
operation.
When installing MKSM on a boat that incorporates keypad buttons, there are no mechanical
switches or buttons to push for engine starting. Using the KBI DPST method of installation,
MKSM activation is not an option. Instead you will be using power to activate the MKSM from
the engine’s starter motor “S” terminal circuit.
If the OEM engine manufacturer or the boat builder reviews the KBI MKSM Theory of
Operation (Pages 13 + 14) and the requirements for DPST-type functionality, then
incorporating the DPST-type function and engineering it into the factory build should be no
problem. However, when installing a MKSM on a boat that has already been built with keypad
button or digital switch starting, the following procedure and hardware (wiring) should be used.
See Figures C1, C2, and C3.
NOTE:
If battery power was insufficient (
˂
7 volts), too weak to enable an engine start or
provide adequate power to the “S” terminal, an emergency start button should be
installed (installed near the controls) and would supply capacitor power to enable the
entire MKSM system when the button is pushed.
