Class 2

Service class 2 codes can only arise in connection with the ENS option.

Class 2 service codes are also related to the parameters of the mains network. Some of the checking procedures therefore overlap with those of service class 1. Your FRONIUS IG unwill react in the same way as in the case of service codes in service class 1.

Code Designation

201 Excessive mains voltage

202 Insufficient mains voltage

203 Excessive mains frequency

204 Insufficient mains frequency

205 Imbalance of mains network impedance

Description

As soon as the mains voltage, after detailed check, has returned to the admissible range, your FRONIUS IG resumes feeding power into the mains network

As soon as the mains voltage, after a detailed check, has returned to the admissible range, your FRONIUS IG resumes feeding power into the mains network

As soon as the mains frequency, after a detailed check, has returned to the admissible range, your FRONIUS IG resumes feeding power into the mains network

As soon as the mains frequency, after a detailed check, has returned to the admissible range, your FRONIUS IG resumes feeding power into the mains network

As soon as the mains impedance after a detailed check, has returned to the admissible range, your FRONIUS IG resumes feeding power into the mains network

Repair

Check mains voltage

If the service code does not disappear, you should contact your installation specialist

Imbalance reaction can be only short termed

206 Absolute reading of mains impedance too high

207 Problems with the mains relay As soon as the mains impedance after detailed checking, has returned to the admissible range, your FRONIUS IG resumes feeding power into the mains network

ENS recognises a faulty mains relay Check in-house line cable cross section
