The tolerance for raising a fault condition is relative to the safe position determined by the system • Faults caused by cutting and reconnecting the cable or the use of a non-Renishaw cable that is manufacturer. not approved.
To achieve full system integrity the evaluation unit must continuously monitor the error condition of The maintenance check intervals will be defined by the system manufacturer according to their risk each readhead in the FORTiS-S FS encoder system, and in the case of fault detection place the assessment. There are no user-serviceable parts within the FORTiS-S FS encoder system.
