If the desired setpoint is not reached on your Emerson Controller, it could be due to a weak calibration spring or leaks from pilot connections. You should check the springs catalog and replace the spring with a stronger one if it is too weak. Also, check the pilot feed connections and ensure proper gas flow.
What to do if the outlet pressure drops below setpoint on Emerson TARTARINI PS/79 Controller?
If the outlet pressure on your Emerson Controller drops well below the setpoint, it could be caused by a clogged filter or swollen pad holders. Clean or replace the filter if it is clogged. Replace the pad holder (key 56) if it is swollen and preventing proper feed flow. Also, replace the pad holder (key 34) if it is swollen.
Why does the outlet pressure increase over setpoint on my Emerson Controller?
If the outlet pressure increases over the setpoint on your Emerson Controller, it could be due to faulty sealing of the pad holders. Replace the pad holder (key 56). Also, replace the pad holder (key 34).
What to do if the outlet pressure is not within the usual values on my Emerson Controller?
If the outlet pressure is not within the usual values on your Emerson Controller, the diaphragms may be damaged. Replace diaphragms (key 10) that show signs of wear. If gas escapes from the silencer (key 45), replace the upper diaphragm (key 10).
How to fix slow response to changes in gas demand on Emerson Controller?
If your Emerson Controller exhibits a slow response to changes in gas demand, it might be due to an insufficient flow rate of the valve seat or an overly large calibration jet. Increase the flow by means of the register/pin screw (key 29). If you have Types PS/79 and PS/80, replace the calibration jet (key 15) with a smaller one.
How to stop overly rapid response (hunting) on Emerson TARTARINI PS/79?
If your Emerson Controller is exhibiting an overly rapid response to changes in gas demand (hunting), it could be caused by an excessive flow rate of the valve seat, a calibration jet that is too small, or improper internal parts assembly. You can try the following: * Reduce the flow by means of a pin screw (key 29). * Replace the calibration jet (key 15) with a larger one (only for Types PS/79 and PS/80). * Check the clearance between the lever (key 39) and the forked stem (key 35).
Why is gas continually escaping from the relief (S) on my Emerson Controller?
If gas is continually escaping from the relief (S) on your Emerson Controller, it is likely due to a defective seal of the pad. The suggested solution is to replace the pad (key 21).
