Facts and Changes

ATS48 used with small motor

Causes and Fixes

It's not possible to modify the soft-starter by replacing the control board because there is an EEPROM inside the power board containing the size ( nominal current, etc... ) and there is an auto-adaptation between both cards. The thermal protection is made with PTC on the heatsink and calculation with the thyristors. The best solution is to replace the ATS to a smaller size.
