Do you have a question about the LOGIK 26-S and is the answer not in the manual?
Questions and answers
Not starting
The LogikaControl LOGIK 26-S may not be starting due to an active shut-off alarm. Possible causes include:
- Emergency stop button open (Code 01)
- Thermal motor overload (Code 02)
- Thermal fan fault (Code 03)
- Phase loss (Code 04)
- Wrong phase sequence (Code 05)
- RS485 communication failure (Code 33, 60, or 62)
Each of these alarms will stop the compressor, and the alarm message must be reset after fixing the cause by pressing the R button. Also, a GENERAL reset is only allowed when the compressor is OFF.
