The viscosity control control valve on the corn syrup blending unit overshoots small output changes and then sticks until the controller output changes another 6 percent. Air supply is clean at 80 psig, the I/P output follows the controller signal, and the position feedback moves in steps. Which diagnosis best fits the evidence?
The glycol circulation control valve on the natural-gas dehydration skid overshoots small output changes and then sticks until the controller output changes another 6 percent. Air supply is clean at 80 psig, the I/P output follows the controller signal, and the position feedback moves in steps. Which diagnosis best fits the evidence?
A troubleshooting team on the corn syrup blending unit is using a loop diagram, P&ID, and wiring drawing. The P&ID shows a normally closed solenoid in the shutdown path, while the wiring drawing shows the output energizes to trip. Field testing confirms de-energize-to-trip. What should the technician document?
A PLC discrete input for a permissive on the corn syrup blending unit stays off. The field switch is closed, 24 VDC is present at the field side of the terminal, and 0 VDC is measured at the PLC input terminal. What is the most likely next check?
On the corn syrup blending unit, a DP flow transmitter with square-root extraction reads near zero whenever flow increases rapidly after startup. Both impulse lines were recently blown down, and the equalizing valve was left slightly cracked open. The transmitter calibration checks correctly on the bench. What is the best next action?
