4. SERVICE INSTRUCTIONS

4.1. Programming

Minarc Evo 150/180 has a microprocessor on the A001 card. This can only be reprogrammed in Kemppi
production because great care must be taken, because the connection is in the primary potential and
without galvanic isolation.
Normally there is no need for reprogramming, but in a special case, the only possibility is to fit a
replacement control card that is factory programmed. In these cases please contact:
technicalservice@kemppi.com

4.2. Calibration

Minarc Evo must always be calibrated if an A001 control card or a Z001 main circuit card is replaced with
a new one. Otherwise machine maximum/minimum current and/or panel display may be out of range.

example and guide on how to use the different functions in calibration mode.
