SUMMARY – PROFIBUS-PA
Mounting to Actuator (Valve)
The SRD991 can be mounted to linear or rotary actuators
Connection and Startup
When connecting the supply air and applying a current source to the input terminals, pay attention to polarity An initial
startup required no additional equipment
Use the local push-buttons to change basic parameters such as type of actuator, side of installation, valve opens/closes with
increasing setpoint value, and characteristics curve of the valve (values set ex-factory: stroke actuator, mounting side: left,
valve opens with increasing setpoint value, linear characteristics curve)
Thereafter, an AUTOSTART can be performed during which the SRD991 determines independently the geometric data of the
actuator as well as control parameter, to ensure an optimized operation with the attached valve
