1.   Turn the power switch ON. 

2.   Set the desired feed rate on the RPM display using the up or down arrows. 

3.   Flip the motor switch to AUTO. 

If the additive feeder is installed correctly, it should begin operation at the desired RPM when 
the processing machine screw is in operation. 

Power Switch. This switch turns the control ON and OFF. 

Motor Switch.  This switch has three (3) positions: 

•  OFF stops the auger motor. 
•  AUTO starts normal automatic operation. 
•  MANUAL operates the auger at the set point as long as the switch is held in this 

position.  Use this feature when calibrating the feeder or during cleanout. 

Motor Light.  This indicator lights when the auger motor is turning. 

Auger Speed.  This LED displays the auger speed setpoint. 

The Timer/Counter control is designed for use with cyclical processes like injection molding 
and features a timer and counter module.  It also acts as a cycle override safety timer. 

This feature of the controller assists in calibration of the additive feeder (See Page 19 for 
specific calibration instructions). 

1.    Set the timer to the desired calibration period, using the round timer keys (See the 

timer information sheet for additional information). 

2.    Start the additive feeder by flipping the MOTOR switch to the MANUAL position. 

3.    When the timer times out, the feeder automatically stops. 

This component of the controller allows the operator to override the molding machine shot 
cycle when the additive feeder motor is running in AUTO mode.
