MOTOR CONTROL MODULE
The motor control module receives a command from the rate potentiometer
located on the remote control box and generates a variable pulse width
command to the formulation motor. The command signal is added to the feed
back signal generated by the tachometer decode circuit and a difference
amplified drives the variable pulse width generator.
This module also contains the circuits needed to operate the fault indicator in
the remote control box and to provide the voltage to open the 3-way solenoid
valve. Pin outs for the motor control module are as follows:
