Remote control As an alternative to using an SZS unit, it is better for many applications to be able to set the intermediate positions remotely, e. g. from the switchgear cubicle, instead of at the damper actuator itself. his arrangement requires the use of a positioner and a modulating damper actuator. Another advantage is that it allows several actuators to be connected in parallel. he SZS mid-position switch unit is suitable for direct mounting on ype SM damper actuators or on ype P feedback potentiometers.
