Adjustment Recommendations for 

Monitor Applications

Low amplitude/high frequency monitor trim oscillations 

can occur if the monitor regulator pressure setting is 

adjusted too closely to the working regulator pressure 

setting and/or if the monitor pilot supply regulator 

pressure setting is adjusted too closely to the monitor 

regulator pressure setting.  The monitor pressure 

setting should be adjusted so it is at minimum two 

times the pilot proportional band pressure above the 

working regulator pressure setting.  The monitor pilot 

supply pressure setting should be adjusted so it is at 

minimum 5 psig / 0,34 bar plus the monitor minimum 

differential pressure above the working regulator 

pressure setting.  These adjustments must be made 

such that other governing pressure limits, such as 

casing ratings, pilot maximum differential pressures, or 

regulatory limits, are not exceeded.

wide-Open Monitor (Figure 8)          

Installation

  1.  For both the wide-open monitoring regulator and   

       the working regulator, perform the Standard       

       Single-Pilot Regulator Installation section 

       through step 6.

  2.  Connect the control line of the wide-open  

       monitoring regulator (Figure 8) to downstream 

       piping near the working regulator control line  

       connection.  During normal operation the wide- 

       open monitoring regulator stands wide-open  

       with the pressure reduction being taken across  

       the working regulator.  Only in case of working  

       regulator failure does the wide-open monitoring  

       regulator take control at its slightly higher setting.

Startup

Repeat this procedure in turn for each regulator in 

the installation.
  1.  Slowly open the pilot supply line hand valve.
  2.  Slowly open the upstream block valve and 

       partially open the downstream block valve for   

       minimum flow.
  3.  Slowly open the hand valve in the control line 

       and adjust the pilot setting if necessary.  Set   

       the monitoring regulator at a slightly higher control  

       pressure than the working regulator.
  4.  Completely open the downstream block valve.
  5.  Slowly close the bypass valve, if any.
