Lainox ROD INS

What does Lainox ROD INS mean?

The ROD INS alarm indicates the rod (core) probe is not inserted when a temperature-based cycle requires it, as governed by parameters r17 and r18. As a consequence the temperature-based cycle in use is switched to a time-based cycle. It is a usage condition prompting the operator to insert the core probe so the controller can run true core-temperature control.

Symptoms

• ROD INS alarm message appears on the controller.
• The rod (core) probe is not inserted into the product.
• A temperature-based cycle switches to time-based operation.
• The cycle no longer ends on measured core temperature.

Common causes

• Operator started a temperature-based cycle without inserting the rod probe.
• Rod probe pulled out or dislodged during loading.
• Probe not seated deeply enough to register as inserted.
• Faulty rod probe affecting insertion detection.
• Incorrect parameters r17 or r18 governing insertion detection.

Diagnostic steps

1. 01

   Insert the rod probe correctly

   As the manual directs, check the correct insertion of the rod probe into the product so the temperature-based cycle can use it.

2. 02

   Check parameters r17 and r18

   Verify the value of parameters r17 and r18 that govern rod-probe insertion detection for the cycle.

3. 03

   Reseat into the thickest part

   Place the probe into the thickest part of the product so it registers as inserted and gives a representative core reading.

4. 04

   Confirm temperature control resumes

   Verify that with the probe inserted the cycle runs as temperature-based rather than falling back to a time-based cycle.

When to call a professional

ROD INS is usually corrected by inserting the core probe properly. If the alarm persists with the probe clearly inserted, the rod probe or its insertion-detection wiring may be faulty and should be tested or replaced by an authorised technician so the appliance can reliably perform core-temperature-controlled cycles.
