2. Programming parameter 26 to zero programs the
MSS-200 for variable speed pump application with
overspeed. The frequency programmed in parameters
20, 22 and 26 then become the RPM at which the
engine will shutdown.
Engine Warm Up Duration Parameter
When the application is a variable speed pump with
overspeed, this parameter can be used as a warm-up
period from 8 to 38 seconds in 2 second increments.
Standby Mode Parameter
Standby mode on the MSS-200 can be programmed to
either to consume electricity or to consume no electricity.
In the standby mode that consumes electricity, the
controller is activated by a ground contact to the AUTO
terminal and deactivated when ground from the AUTO
terminal is removed.
During standby mode, the top right
AUTO LED (Figure 27)
is lit indicating that the unit is in standby mode.
Figure 27. Standby Mode (Auto)
In the standby mode that does not consume electricity,
the MSS-200 is activated when the unit receives a battery
plus signal. When battery positive signal is removed, the
engine will shut down immediately.
NOTICE
When the MSS-200 is programmed in pump mode
overspeed shutdown delay becomes a fixed zero
second delay.
STANDBY MODE
OPERATION (AUTO MODE)
Basic Operation
The MSS-200 can be controlled directly from the face of
the MSS-200 controller by simply pushing either MAN OFF/
SET, and AUTO buttons (Figure 28).
Figure 28. MSS-200 Control Buttons
Only when the MSS-200 is powered up and parameter
30 (standby mode) has been 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 (cool down cycle) is programmed with a
cool down cycle time, pressing the OFF/SET button once
will start the cool down cycle. Pressing the OFF/SET button
again will override the cool down cycle and the engine will
shut down immediately.
Pressing the
AUTO button (Figure 29) will cause the AUTO
LED to light up, indicating that the engine is in standby
mode.
