Vacuum Controller (Etron) - VCE-100
Setup Instructions:


Quick start guide:

Low voltage wiring:

  • Pin 1 (Analog Ground) should connect to the analog ground of the VFD

  • Pin 2 (0-10V) should connect to the analog external reference pin on the VFD

  • Pin 3 (Motor Forward Switch 1) should connect to the “Start” or “Forward” pin of the VFD

  • Pin 7 (Motor Forward Switch 2) should connect to the 24V or common pin of the VFD

 Pins 3 and 7 provide a solid-state dry contact as a start signal to the motor. These pins are electrically isolated from the rest. The maximum voltage rating across these pins is 35V. They can be used in a source or sink configuration. The length of the low-voltage cable should be kept as short as possible.

High voltage wiring:

Normal pin connections:

  • Pin 16 (Wash) should connect to the 120V power through the “Wash” switch

  • Pin 18 (Run) should connect to the 120V power through the “Run” switch

  • Pin 20 (Line) should connect to the 120V power line directly for constant power

  • Pin 22 (Neutral) should connect to the 120V neutral line directly

Alternate - When the Run is supplied by the power:

  • Pin 16 (Wash) should connect to the 120V power through the “Wash” switch.

  • Pin 18 (Run) should connect to the 120V power through a jumper when power is used as the “Run” or “Milk” signal

  • Pin 20 (Line) should connect to the 120V power line through the “Run” switch when power is used as the “Run” or “Milk” signal

  • Pin 22 (Neutral) should connect to the 120V neutral line directly

Bond the power safety ground to the back plate:

Tubing:

Attach a flexible vacuum level sense hose to the left nipple of the vacuum port. The hose must have an inner diameter of no more than 0.19”.
