OPERATION (AUTO MODE)
Repeated Engine Starts Parameter
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 (Figure 25) will blink, indicating that the system is
in repeated start mode.

Pause Between Repeated Engine Starts Parameter
Pause between repeated engine start is the period between
each repeated start-up attempt. The range for this pause is
between 5~75 seconds in 5 second increments.
Overcrank Parameter
Overcrank is defined as 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.
Engine Cool-Down Cycle Parameter
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 throttle control or compressor.
The engine will run without load for an amount of time
established by the customer. Cool-down cycle time can be
programmed from 0~900 seconds in 60 second increments.

REPEATED START MODE
NOTICE
Engine will not go into repeated start mode if the engine
is started manually by pressing the MAN button.
Oil Pressure Switch Parameter
This parameter is used to select the type of oil pressure
switch being used on the engine, i.e., normally closed (NC),
normally open (NO) 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 monitored and shutdown system, i.e., EP-
100, MC-536 or MC-6K.
In the solo mode the MSS-200 can also be programmed
to monitor oil pressure. This feature adds starter motor
protection by preventing the starter motor from engaging
when the engine has oil pressure, or if the pressure switch
wire has been disconnected.
Applications requiring shutdown for other critical functions
like high temperature or pump pressure can connect the
switch wires to the oil pressure input.
Oil Pressure Switch Time Delay Parameter
With this parameter a delay of 1 to 15 seconds can be
programmed for oil pressure switch override. This feature
gives the engine a certain amount of time to build up
oil pressure during engine start prior to monitoring for
shutdown.
This parameter is required only when the MSS-200 is used
in solo mode and when the oil pressure parameter #12 is
programmed to either a normally open or normally closed
switch contact.
Auxiliary Engine Monitor Parameter
This parameter programs the MSS-200 controller to either
a stand-alone application (solo) or to an application utilizing
an optional engine shutdown device, i.e., EP-100, MC-536
or MC-6K.
NOTICE
The cool-down cycle can only be used when the
controller’s standby mode (parameter 30) is programmed
to consume electricity.
NOTICE
Connecting a small jumper wire from the overspeed
(O/S) terminal to the OEL (oil) terminal eliminates the
need for adding an extra relay for overspeed shutdown.
