Code
JetFlow (JF) Backup
Control Mode
The positioner is controlling the
position based on actuator pressures
instead of the feedback sensor.
The JetFlow feedback linkage is
possibly broken, or the feedback
arm needs to be rotated because
the sensor is out of range.
JetFlow (JF) Calibration
Error
The relay is not moving far enough.
Check relay installation, alignment,
O-rings, and feedback magnet.
Check supply line and pneumatic
tubing. Re-run the relay
characterization.
JetFlow (JF) Can’t Open
The JetFlow relay appears to be
unable to move to a pressurize state
and is not responding. This could be
due to a broken or out of calibration
sensor, a broken piezo, stuck spool,
malfunctioning relay, or a wire
connection problem.
Check the relay for sticking
problems. If the positioner still does
not operate replace the piezo,
and/or relay assembly.
Check air supply and tubing
connections.
JetFlow (JF) Can’t Shut
The JetFlow relay appears to be
unable to move to a depressurized
state and is not responding. This could
be due to a broken or out of calibration
sensor, a broken piezo, stuck spool,
malfunctioning relay, or a wire
connection problem.
Check the relay for sticking
problems. If the positioner still does
not operate replace the piezo,
and/or relay assembly. Check air
supply and tubing connections.
JetFlow (JF) Inner Loop
Offset Out-of-Range
Warning
The Inner Loop Offset is not close to
expected value.
Verify the feedback magnet is not
loose. Replace the poppet relay.
JetFlow (JF) Pressure
Control Locked
The positioner is using pressure
readings to keep the valve steady.
Use the Valve Stability
Configuration Switch to toggle the
Valve Stability from "Lo Friction" to
"Hi Friction" mode. Set the “Hi
Friction” window.
JetFlow (JF) Stroke
Calibration in Progress
A stroke calibration sequence is in
progress.
The calibration can be canceled
from the Sensor Calibration page of
the DTM, from the handheld, or by
briefly pressing the QUICK-CAL
button.
