Common PAT Hirschmann Error Codes

The PAT Hirschmann error codes listed in the error table explain the various faults, which can occur with the Load Moment Indicator (LMI).  Faults within the microprocessor system should only be repaired by trained service personnel, please contact us if you need support for matters that are beyond your technical capabilities.
