Lainox SANITISING DURATION Error Code

What does Lainox SANITISING DURATION mean?

The SANITISING DURATION alarm is raised when a sanitising alarm is not cleared within the maximum duration of the first phase, as governed by parameter r23. The controller stores the alarm, interrupts the cycle in progress, and activates the alarm relay. It indicates the sanitising process could not satisfy its required conditions within the allowed time.

Symptoms

• SANITISING DURATION alarm message appears.
• The first-phase sanitising condition was not met within the allowed time.
• The cycle in progress is interrupted.
• The alarm is stored by the device.
• The alarm relay output is activated.

Common causes

• Sanitising temperature not reached within the maximum first-phase time.
• Rod probe not correctly inserted, preventing the cycle from progressing.
• Underperforming heating or refrigeration affecting the cycle.
• Maximum-duration parameter r23 set too short for the load.
• Excessive or improperly arranged load.

Diagnostic steps

1. Check parameter r23

   As the manual directs, verify the value of parameter r23 (the maximum first-phase duration) to confirm it is appropriate for the product and process.

2. Verify the rod probe and load

   Confirm the rod probe is correctly inserted and the load is not preventing the sanitising condition from being met in time.

3. Inspect cycle performance

   Check that the appliance is reaching the required cycle conditions normally; underperformance can cause the first phase to overrun.

4. Restart after correction

   Once the probe, load, and parameter are correct, restart the sanitising cycle and confirm it completes the first phase within the allowed time and the alarm relay clears.

When to call a professional

If the parameter, probe, and load are correct but the first phase still overruns, the appliance may not be reaching the required conditions and needs a technician to inspect the heating or refrigeration system. Because sanitising is hygiene-critical, do not treat an interrupted, time-failed cycle as effective; have qualified personnel resolve the underlying cause before reuse.
