Reliable operation of the insertion devices is important to users of beamlines. The most unpredictable fault is due to a soft error in optical absolute encoders due to radiation. There are several solutions to avoid such faults, e.g. by increasing the distance of the encoder from the beam, by a lead shield cover and finally by adopting an auxiliary position sensing devices to help recovery from a fault. Efforts to improve operational reliability of the TPS ID controls will be discussed.
