Ceia THS - Applications at High Speed (Belt Speeds Greater than 60 M;Min); Programming Used in a few Common Types of Installation

THS – FI022GB2K8v3 --- V - MAINTENANCE

Applications at high speed (belt speeds greater than 60 m/min)
In this case, the response times of the photocell, metal detector and ejector can not be ignored. We would generally
advise users to check operation of the ejector experimentally, changing its position and adjusting parameter ED.
