What does UniMac error code EI0F mean?

A UniMac UW pocket hardmount washer-extractor can switch off its infrared port, so no one can send data to the machine by accident. When someone tries a transfer while the port is off, the control shows EI0F. Nothing is broken. The port simply stays off until someone enables it by hand or the tool is re-aimed at the window. Production cycles are not affected while the port is off. The manual lists an infrared setting that has been switched off, a tool aimed away from the infrared window, dirt or film covering the window, and a control setting that was changed by mistake. The usual solution is on the control itself: turn the infrared option on in the way the programming manual describes, then try the transfer again. If the control will not let you enable it, or the message stays after you do, we should look at the control.

Affected models and control systems

This applies to the PHM1263R family of UniMac UW pocket hardmount washer-extractors, models UWL, UWN and UWU 035 to 125, such as the UWL035K12. EI0F is the infrared disabled message on this control.

Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.

What you may notice

  • EI0F on the display when a transfer starts
  • Tool unable to connect
  • Normal cycles
  • Port working again after it is enabled

Possible causes

Listed in UniMac's documentation

  • An infrared setting that has been switched off
  • A tool aimed away from the infrared window
  • Dirt or film covering the infrared window
  • A control setting that was changed by mistake

Other likely causes — what usually sits behind error code EI0F on this control. A technician confirms which one it is before any part is replaced.

  • A previous owner or crew who turned infrared off to keep outsiders from changing programming
  • A settings reset that returned the port to its factory off state
  • A window cover that was added later and also blocks the beam

Safe checks before calling for service

✓ What an operator can do
  1. Enable infrared manually on the control, or re-aim the tool and try again.
  2. Make sure the window is clean.
  3. Hold the tool steady during the transfer.
  4. If you cannot enable the port or EI0F stays, note what you tried and call us.

How a technician diagnoses error code EI0F

  1. Read the code and check whether the infrared option is switched on in the control's settings.
  2. Enable the port and confirm that the setting is saved.
  3. Clean the window and confirm that the tool is aimed correctly.
  4. Run a test transfer with a known good tool.
  5. Test the infrared receiver only if the port is on but nothing is received.
! Leave this to a technician
  • Turning options on in the control's settings changes how the machine accepts programming.
  • Confirming a bad receiver needs a known-good tool and the maker's service steps.
  • Opening the control to check the board puts a person near live circuits.
