FL-3000/4500: How do I measure output voltage on a power supply?

Topic

  • How do I measure output voltage on a FL-3000/4500 power supply?
  • How do I measure output voltage on a FL-3000/4500 with a dual power supply?

Environment

  • Product: FL-3000, FLW-3000,  FL-4500 
  • Component: Power Supply
  • Control System:

Steps

  • There are two types of power supplies for FL-3000/4500 series. Voltage measurements will be different depending on the style.
    • Solid colored wires. (Left Picture)
    • Black wires with colored stripes. (Right Picture)

  • There may be one power supply or two.
  • Follow these steps for a single power supply with solid colored wires:
  1. Unplug black power plug from J3 on the driver.
  2. Measure voltage between the red and black wire. You should get 24VDC.
  3. Measure voltage between the red and orange wire. You should get 24VDC.
  • Follow these steps for a single power supply with black wires with colored stripes:
  1. Unplug black power plug from J3 on the driver.
  2. Measure voltage between the red striped wire and the solid black wire. You should get 24VDC.
  3. Measure voltage between the red striped wire and the orange striped wire. You should get 19VDC.
  • Follow these steps if there are two power supplies:
    • Note: If one power supply is faulty, both should be replaced as extra strain is put on the running power supply.
  1. Unplug one of the black power plugs from Y harness.
  2. Follow the steps listed above based off of the style of power supply.
  3. Unplug 2nd black power plug from Y harness and perform same measurements as before.
  4. Connect both power plugs back into Y harness.
  5. Disconnect Y harness from J3 on the driver.
  6. Measure voltage between red and black wires on pins 1 and 2. You should get 24VDC.
  7. Measure voltage between red and black wires on pins 3 and 4. You should get 24 VDC.
