INSTALLATION
SERIES : EPR (ROTARY TYPE)

The positioner type : EPR in a rotary type can feedback should be mounted to make an alignment feedback shaft of the rotary (quarter-turn operation) actuator. A rotary actuator should be installed the following figure by using L-type bracket and also, is availble for block-type bracket ( ) with this positioner and fork-lever rotary joints are available that tolerate small misalignments between positioner and actuator shaft.
