4 MPH SWITCH MODULE
The 4 mph switch module stops the output of formulation in the syncroflow mode
when the vehicle speed slows to 4 miles per hour or below. This module measures
the analog voltage output of the speed decode module and compares it to a
reference voltage to determine if the speed is above, or below the preset level. If
the speed is above the preset level a relay on the module is energized, which in
turn allows the output solenoid valve to open, and the formulation pump motor to
operate. Below the preset level the module closes the solenoid valve and stops the
formulation pump. In manual mode the relay on the module is energized at all times
regardless of vehicle speed. The connections to the module are as follows:
