Digital Feed Unit (DFU)

The DFU has several connections: electrical, internet and fluids. For fluids this includes water supply, water out, coolant supply, and coolant out ports on the unit. View connection diagram

Physical Mounting

Location Requirements

• Considerations for location in the building:
  • Typically, a centralized location of your plant works well where the unit can reach the most CNCs in the least amount of plumbing
  • Locate where a coolant source (barrel, tote, etc) is easily accessible and can be changed out
  • Locate where services such as water, power, and internet are established or can be

Wall Mounting Guidelines

• Considerations for mounting on a wall:
  • Physical size and mounting are documented in our drawing section of manual
  • Position DFU about 5.5 - 6 feet high on wall as we have found this height range is the best overall for any maintenance or inspections needed
  • Provide clearance of at least 36 inches for ease of access and troubleshooting
  • DFU weighs approx. 55 pounds, make sure your chosen mounting location can accommodate this
• Mount on wall with no or very low vibration
• Consider access for plumbing
• Installation of ball valves for the water supply, water output, and coolant output ports in case of quick shut off

Caution

Our water flowmeter requires users to provide filtering. Particles must not exceed 0.50mm. Before connecting water source flush pipes carefully to avoid blocking the water turbine caused by particles from the pipe installation.

Electrical Supply

• 120VAC/15amp source required to power Digital Feed Unit
• DFU uses and IEC style receptacle if you want to source longer cable

Level Sensor - Monitors coolant supply

• Components provided in kit - View Kit
• JUNCTION BOX WIRING:
  • Insert Level Sensor cable into grey junction box if it is not already assembled
  • Insert flying lead end of M12 cable (one orange end) - terminate to desired length
  • Use provided WAGO connectors to wire per below:
    • Level Sensor Red wire to >>> BROWN wire on M12 cable
    • Level Sensor Green wire >>> BLUE wire in M12 cable
• Yellow wire NOT USED
• Mount Terminal Box in desired location - and router wire convenient for uses

Connect Metalworking Fluid

• Components provided in kit for - View Kit
• Connect with hose kit provided in your shipment.
• Inlet: Connect to fresh coolant
• Return: Return non-mixed fluids to tank. For relief pressure if ever required.
