Page 33: Information About The Traverse In Slow Speed -Connection Of Traverse Measuriung Device
During the operation with slow speed traverse information, the upper receiver elements are only muted if information a +24 V signal is given to KAST. This signal is provided by a traverse measuring system (e.g. Fiessler AMS, or NC) which indicates that the traverse has been actually covered. By this, the upper receiver elements remain activated as longh as possible even in the case of a very low slow speed, and interme- diate stops during slow speed. -
