4.3  Manual/automatic 

switchover

The positioner output is routed to the actua

-

tor over the manual/automatic switchover. In 
automatic mode, the positioner is in closed-

loop operation. In manual mode, the output 
pressure of any supply pressure regulator is 
directly applied to the actuator. This creates 
a manual bypass of the positioner.

The manual/automatic switchover unit is 
mounted directly onto Types 376x and 373x 
(see Fig. 12) or on an adapter plate with 
hook-up to the actuator (Fig. 15).
The Type 4708-53 or Type 4708-54 Supply 
Pressure Regulator can be directly mounted. 

All other supply pressure regulators can be 

connected to the manual/automatic switcho-
ver unit using piping (hook-up).

4.3.1  Mounting on positioners
