IDPlus 902/961/971/974 — Stores the dwell time of the Pb3 value outside range SLH...SHH (HACCP log, n=1...8, no effect on regulation)

Eliwell tC n: Stores the dwell time of the Pb3 value outside range SLH...SHH (HACCP log, n=1...8, no effect on regulation) This fault usually isn't an immediate stop, but should be checked soon.

Possible causes

Extended door opening, product loading, or equipment failure caused a sustained threshold excursion
Defrost/cooling capacity insufficient, delaying return within permitted range

Check steps

Review HACCP log (AL folder, tC n) to establish duration and timing of the excursion
Check cooling capacity/defrost cycles and door usage; reset log via rES function if needed

Affected parts

Pb3 probu
evaporatör/kondenser bileşenleri

Safety note

General safety note: switch off power before working on the device.
