Step 4:  Air Connections

1.  Connect Out 1 Port on Gauge Block to Actuator Inlet
2. Connect Air Source to In Port on Gauge Block (Recommended
   Air Pressure 70-90 PSI, 90 PSI max.  Coalescing fi lter must be  
   used on supply air)
3. Gauges are pre-mounted on Gauge Block

Step 5: Electrical Connections

•  Terminals +11 and -12 used for 4-20mA Analog Input
•  Terminals +31 and -32 used for 4-20mA Feedback Loop       
    24VDC Powered Analog Output

Mounting Instructions | 1177E-EP2 Control Valve


Option 1:  Using the Pushbuttons and LCD Display on the 

1.  Feed in Air Pressure  
2. Feed in electrical supply power
     •  Feed in setpoint current 4-20mA (terminals +11/-12) 
3. Check mount:
     •  Press and hold 


, plus






until operating mode  

     1.3 (manual adjustment within the sensor range) is displayed. 


     •  Press





 to move the actuator/valve into the mechani- 

     cal end position; check the end positions; rotation angle is   
     displayed in degrees; for high-speed mode or if the actuator/ 
     valve do es not move, press 


and then


simultaneously to  

     move in one direction and then



and then




     to move in the other direction.
Recommended range: 
-  Between -57 to 57° for rotary actuators 


4.  Run Autoadjust
     •  Press 


 and hold down until  


 is displayed; 

     release the 



     •  Press 


 again and hold down until the countdown ends  

     •  Release 


; this starts Autoadjust 

     The Autoadjust process may take up to 5 minutes to fi nish,   
     so please be patient. When Autoadjust is complete, the pa- 
     rameters will be stored automatically and the positioner will  
     revert to operating mode 1.1 (Control Fix mode). 
     If an error occurs during Autoadjust, the process will be         
     terminated with an error message. If this happens, press and  
     hold down 




for approximately three seconds. The unit  

     will switch to the operating mode 1.3 (manual adjustment  
     within the sensor range). The mount is checked and corrected  
     if necessary. Autoadjust then runs again.

Option 2:  Using a HART Communicator

1.  Feed in Air Pressure  
2. Feed in electrical supply power
    •  Feed in setpoint current 4-20mA (terminals +11 / -12) 
3. Connect HART communicator to terminals 11 and 12 coming  
    from the positioner
4. Go online with the communicator. 
Then go to Settings
