MSS - 200 Programming
automatic engine start system be installed
into a mobile vehicle that has a manual
transmission.
6. A 1N4007 diode must be used when
using any of LOFA’s products to suppress a
potential high voltage spike. Install diode as
close as possible to the solenoid to prevent
high voltage spikes (up to 1000V or more
which can occur momentarily when a relay
or solenoid is switched off). Relay contacts,
electronics, etc., can be damaged, or
malfunctions can occur if these spikes reach
the electrical network without suppression.
Refer to diode installation sheet supplied with
each product for installation instructions.
Every electronic product from LOFA is supplied
with qty. 2 diodes. Please note installing the
diode incorrectly or reversing the battery’s
polarity will damage the diodes.
7. The LOFA Industries, LLC warranty does not
cover consequential damages. Applications
that could cause consequential damages
if the engine failed to start or if the engine
were to shut down should implement a
backup system, i.e., backup engine or
generator, auto dialer, satellite/cell phone
monitoring system.
BASIC PROGRAMMING INFORMATION
Each MSS-200 is factory programmed to the
most commonly used values, but can be easily
changed by the customer or by LOFA Industries.
The following information is required for
programming the MSS-200.
•
Number of pole pairs, or if used with
a proximity switch, number of pulses
per revolution
•
Belt ratio (pulley diameter. = D1÷ D2)
D1= Crank Shaft Pulley
D2 = Alternator Pulley
•
Rated engine speed RPM (if required)
•
Over-speed shutdown RPM (if required)
Hertz Calculation Formula
In order to program hertz in parameters 18, 20,
22, 24 and 26, you will be required to enter
the above information specific to your engine
into the following hertz calculation formula.
Refer to this formula when programming hertz.
# Poles x RPM x Belt Ratio

Programming Mode
Programming mode is accomplished by holding
down the OFF/SET button on the
MSS-200 for 2 seconds while energizing the
controller. On some LOFA panels equipped with
auto start, energizing the MSS-200 is
accomplished by turning the key switch to the
left position marked auto start. Releasing the
OFF/SET button will bring you to parameter #0
“PRE-HEAT DURATION” indicated by the
blinking #1 LED. Pushing the OFF/SET button
moves to each parameter in ascending order
and saves the programmed value. The MAN
button decreases while the AUTO button
increases the programmed value.
Basic Operations
The MSS-200 can be controlled directly from the
dial of the MSS-200 by simply pushing either
AUTO, MAN and OFF/SET. Only when the
MSS-200 is powered up and parameter 30 is
programmed to consume electricity will the
AUTO and MAN buttons control the engine.
Pressing the MAN button manually starts the
engine. Engine will continue to run until the
OFF/SET button is pressed again or until the
power is turned off. If parameter 10 is
programmed with a cool down cycle, pressing
the OFF/SET button once will start the cooldown
period. Pressing the OFF/SET button
again will override the cool-down cycle and the
engine will shut down immediately. Pressing the
MSS - 200 Programming
AUTO button will cause the AUTO LED to light
up, indicating that the engine is in standby
mode. If AUTO LED is not lit the engine will not
start automatically. Note: A blinking AUTO LED
during power-up indicates that the auto start
input was activated and prevents the engine
from starting.
Preheat #0
The duration period of the preheat can be
programmed by time (in 4 sec. increments) or
by ambient temperature if used in combination
with a PT-1000 thermistor.
The preheat by time setting has priority
over ambient temperature. In case of a
defective thermistor or loose wire connection,
it is important that a time value is always
programmed when used in combination with
a thermistor. When using the temperature
thermistor provision, use the following table
for temperature verses time comparison.

The preheat function on the MSS-200 can
also be used in combination with a pre-start
audible alarm. Simply program a preheat
duration and add an alarm to the preheat
output to provide additional safety to your
equipment. Alarms are available as an option
from LOFA Industries, LLC.
Repeated Engine Starts #2
If the engine does not start on the first auto
start attempt, the engine will go into repeat
start mode. The MSS-200 can be
programmed to make a maximum of 15 new
engine start attempts. During repeated starts
the bottom left LED will blink, indicating that
the system is in repeated start mode. Note:
Engine will not go into repeated start mode if
the engine is started manually by pressing the
“MAN” button.
Pause Between Repeated
Engine Start #4
Pause between repeated engine start is the
period between each repeated start-up
attempt. The range for this pause is 5 - 75
seconds in 5 second increments.
Over-Crank #6
Over-crank the maximum time, in seconds,
that the starter motor can be engaged if the
engine fails to receive a frequency via the
alternator’s frequency terminal or proximity
switch pick-up. The over-crank feature
eliminates the need for any manual settings of
starter motor duration usually required for low
temperature conditions.
G/S Generator Load Switch Delay #8
This parameter is primarily used on generator
sets and provides the ability to delay G/S
switch disengagement normally used to shut
off the main electricity-producing generator.
With this programmable feature, the
generator set will continue to produce AC
power from 0-75 seconds after full power is
restored, eliminating power interruptions should
power turn on and off.
Engine Cool-down Cycle #10
This parameter controls the length of time
in which the engine is in its cooling-down
cycle. Once the ground contact is removed
from the AUTO terminal wire, the MSS-200
will shut off the G/S Switch, i.e., generator
set, air compressor, or throttle control. The
engine will run without load for an amount
of time established by the customer. Cool-down
cycle time can be programmed from 0 to 900
seconds in 60 second increments. Note: Cool-
down cycle can only be used when the
controller’s standby mode (parameter #30) is
programmed to consume electricity.
Oil Pressure Switch #12
This parameter is used to select the type
of oil pressure switch being used on the engine,
i.e., Normally Close, Normally Open or No Oil
Pressure Switch. The “No Oil Pressure Switch”
setting must be selected when the MSS-200 is
used in combination with any other auxiliary
engine monitoring and shutdown system, i.e.,
EP-100, MC-536 or MC-6K. In the solo mode
the MSS-200 can also be programmed to
