Symptom checks

MikroFOK Troubleshooting

Start with the visible symptom. Stop the machine if cable movement is blocked, slipping, unstable, or the installed setup is not confirmed.








Possible causes

  • Cable contact is not matching the measured cable OD.
  • Cable jacket is wet, oily, dusty, or damaged.
  • Cable drum or duct route is resisting movement.

What to check first

  • Stop and confirm the cable drum rotates freely.
  • Clean cable jacket and visible contact surfaces.
  • Confirm measured cable OD in the setup wizard.
  • Check duct entry alignment and route resistance.

When to contact support

  • Rollers rotate but cable still does not advance.
  • Correct cable contact or seal selection is uncertain.
  • Visible wear or repeated slipping is present.

Possible causes

  • Wrong cable contact or seal for the measured cable OD.
  • Small cable jacket is dirty, wet, or oily.
  • Visible contact surface wear or contamination.

What to check first

  • Clean the cable jacket and contact area.
  • Measure cable OD again at an undamaged section.
  • Use the setup wizard to confirm the setup reference.
  • Check cable drum feed and duct entry.

When to contact support

  • Slipping repeats with clean cable and confirmed setup.
  • Contact surface wear is visible.
  • Photos or video can show the slip point.

Possible causes

  • Contact setup is too aggressive for small cable.
  • Cable OD is outside the suitable MikroFOK range.
  • Duct route blockage is increasing cable load.

What to check first

  • Stop operation immediately.
  • Inspect the cable jacket at the contact area.
  • Confirm cable OD and setup reference before restarting.
  • Check duct entry for blockage or sharp edges.

When to contact support

  • Any visible cable deformation repeats.
  • The correct small-cable setup is uncertain.
  • Cable damage appears after a short test.

Possible causes

  • Duct route resistance, bend, moisture, or blockage.
  • Cable drum resistance or crossed cable on the drum.
  • Setup mismatch or insufficient cable grip.

What to check first

  • Check cable drum rotation and cable pay-off.
  • Inspect duct route condition and entry alignment.
  • Confirm measured cable OD, duct OD / connection size, and duct ID if known.
  • Apply lubricant only according to site and project rules.

When to contact support

  • The cable repeatedly stops at a similar distance.
  • Route appears clear but movement still stops.
  • Measured data or setup selection is uncertain.

Possible causes

  • Wrong duct holder or duct connection tool.
  • Duct OD / connection size mismatch.
  • Worn or damaged visible O-ring or seal.
  • Duct cut is not square or duct is not seated correctly.

What to check first

  • Confirm duct OD / connection size and duct ID if known.
  • Inspect visible O-ring, seal, and duct seating.
  • Check duct cut quality and entry cleanliness.
  • Do not continue if the duct entry leaks heavily.

When to contact support

  • Leakage continues after reseating and cleaning.
  • Seal or O-ring wear is visible.
  • Duct size or holder selection is uncertain.

Possible causes

  • Wrong duct holder or duct connection tool.
  • Duct OD mismatch or poor duct seating.
  • Visible holder, clamp, or seal wear.

What to check first

  • Stop if the duct moves during operation.
  • Measure duct OD / connection size again.
  • Inspect the visible duct holder and seating area.
  • Confirm the setup reference before restarting.

When to contact support

  • Duct slips repeatedly.
  • Holder or seal wear is visible.
  • The duct size is non-standard or uncertain.

Possible causes

  • Duct route resistance, bends, moisture, or contamination.
  • Cable jacket friction is high for the route.
  • Duct entry or cable nose preparation increases drag.

What to check first

  • Check duct cleanliness and route condition.
  • Confirm cable nose and duct entry are prepared correctly.
  • Use lubricant only when allowed by project and site rules.
  • Do not force the cable when resistance is high.

When to contact support

  • Resistance remains high after route checks.
  • Cable starts to slip or deform.
  • Lubricant use or route condition is uncertain.

Possible causes

  • Cable is crossed, trapped, or pulling from the wrong angle.
  • Drum stand or pay-off path is not stable.
  • Cable tension is too high before entering the machine.

What to check first

  • Stop and correct the cable pay-off path.
  • Confirm the drum turns freely by hand according to site procedure.
  • Remove twists, crossed layers, or sharp feed angles.
  • Restart only after cable feed is smooth.

When to contact support

  • Drum resistance causes repeated slipping or stopping.
  • Cable jacket damage appears near the machine entry.
  • Video of the drum feed can show the issue.

Possible causes

  • Cable OD was not measured correctly.
  • Previous setup was reused for a different cable size.
  • Small cable size is close to a setup boundary.

What to check first

  • Measure cable outside diameter with a caliper.
  • Compare measured data with the MikroFOK setup wizard.
  • Inspect cable jacket for slipping or deformation marks.
  • Record installed contact and seal details before operation.

When to contact support

  • Cable OD is uncertain or near a boundary.
  • Slipping or cable deformation continues.
  • You cannot confirm the installed setup.

Possible causes

  • Duct OD / connection size was not measured correctly.
  • Duct holder does not match the duct connection.
  • Seal or O-ring condition affects seating.

What to check first

  • Measure duct OD / connection size again.
  • Check duct ID if known.
  • Inspect visible holder, seal, and duct seating.
  • Use setup wizard data for support review.

When to contact support

  • Duct size is not a standard match.
  • Air leakage or duct slipping repeats.
  • You are unsure which duct holder is installed.

Possible causes

  • The cable outside diameter is outside MikroFOK range.
  • Measurement was taken on a damaged or oval cable section.
  • The job may require another machine or support review.

What to check first

  • Measure cable OD again at a clean, undamaged section.
  • Check the machine label and setup wizard before operation.
  • Do not force cable outside the supported range.
  • Capture cable and duct measurements for support.

When to contact support

  • Measured cable OD remains outside range.
  • Machine selection is uncertain.
  • You need application review before operation.

Possible causes

  • Contact setup is not suitable for very small cable.
  • Cable is already damaged, oval, or soft at the contact point.
  • Duct route resistance is causing excessive load on the cable.

What to check first

  • Stop operation and inspect the jacket before continuing.
  • Confirm cable OD and cable condition with a caliper and visual check.
  • Review setup reference before any restart.
  • Check duct entry, route resistance, and cable drum pay-off.

When to contact support

  • Small cable deforms even with confirmed setup.
  • The cable size is close to the lower application limit.
  • Support should review photos and measured values before operation.

Possible symptoms

  • Repeated air leakage at the duct entry.
  • Repeated cable slipping or unstable grip.
  • Small cable deformation with clean setup.
  • Visible wear, cracking, flattening, or contamination.

What to check first

  • Stop and inspect only visible O-rings, seals, and contact surfaces.
  • Clean accessible surfaces after operation.
  • Record photos of visible wear or contamination.
  • Compare symptoms with setup and measurement data.

When to contact support

  • Wear is visible or the same symptom repeats.
  • You need spare part or setup identification support.
  • Send photos and machine serial number with the request.
