1 ~ 125

This  is  to  change  the  Profibus  PA  address  to  1  –  125  manually  on  the  site.  “126”  is  a  factory 
setting. 

 

 
 
12. Maintenance / Service 

 

12.1 Preliminary Check Points 
 

12.1.1 Voltage 

- The positioner commonly requires 4-20mA @ 24VDC for operation. 
- Voltage drop (impedance):    Without HART – 8.7VDC (435Ω  @ 20mA) 

                                                            With HART – 9.4VDC (470Ω  @ 20mA) 
12.1.2 Electrical Connections 

Check polarities (+, -) of 4-20mA input signal definitely and make the electrical connections. 
 

12.1.3 Pneumatic Connections (see 8.1, 8.2) 
 
12.1.4 Supply Air Quality 

A  supply  air  should  be  definitely  clean  and  compressed  free  of  water,  moisture  or  oil  in 
conformance with IEC 770 and ISA-7.0.01. 

 
12.2 Module Parts 

① RTQ Coil Assembly (spare part No. 12) 
② Pilot Valve Assembly (spare part No. 5) 
③ PCB Control Board Assembly (spare part No. 3)
