GENERAL DESCRIPTION
The KE14010 Feeder Controller accepts the signal from a MCX130A1002 Ultrasonic Sensor or an ACX104C1167 Potentiometer Sensor and actuates an EDC on a hydrostatic pump for the auger on an asphalt paving machine. The feeder controller controls the height of the asphalt pile ahead of the screed. When used with an ultrasonic sensor and an external setpoint potentiometer, the distance between the sensor and the asphalt pile can be controlled from approximately 9' to 34'.
The Control has (3) trim pots to adjust the offset voltage, gain and maximum output current and (3) LEDs to indicate +12 V power, +8 V regulator and output current. The +8 V regulator terminal can be used to power the ACX104C1167 Potentiometer Sensor and/or to power an external setpoint potentiometer when the MCX130A1002 Ultrasonic Sensor is used. An external switch can be connected to change the gain from high to low. It has a 10-position terminal strip for external connections. The maximum output current is adjustable from 75 to 150 mA.

FAILURE MODES AND WARNING
Automatic controls are intended to move machine elements without operator input. This motion can be dangerous to persons unfamiliar with the intended control action. Exercise care when operating the automatic control.

This control uses a sensing signal which cannot be seen. This creates an extra danger of unforseen stopping and starting of machine components. Advise operators to turn the control OFF when people are near the sensor or the controlled machine element.
