Identiﬁer Indication and resolution

G - - -

Any sequence starting with a Green light ﬂashing ﬁrst is a normal operating mode and indicates that there
are no internal problems.

GGGG

No errors, alerts, or warnings.

GGGY

MPC active - The command is below the 1% command limit for tight shutoff feature. This is a normal condi-
tion for a closed valve. To clear the condition, adjust the command signal above the speciﬁed MPC value, or
disable the feature by moving the Tight Shutoff switch to the off position and recalibrating.

GGYR

LED test mode, Initializing - This sequence should only be visible for 3 sequences when powering up the unit.

Y - - -

Any sequence starting with a yellow light indicates that the unit is in a special calibration or test mode, or
that there was a calibration problem.

YYYY

Relay not operating during calibration – Most Likely the Air supply is not connected. Could also be due to
a bad pneumatic relay, failed electronics, or a loose or bad connector from the electronics to the relay.

YYYR

Command minimum saturated - Calibration error indicating that the 4-20 mA signal corresponding to the
minimum command was too low. Adjust the signal to higher range and re-do the calibration. This error
may be cleared by brieﬂy pushing the quick-cal button, which will force the positioner to use the parameters
from the last good calibration.

YYRR

Command span - Calibration error indicating that the 4-20 mA signal was below the minimum calibration
span. The minimum calibration span is 3.0 mA. This error may be cleared by brieﬂy pushing the quick-cal
button, which will force the positioner to use the parameters from the last good calibration or if the

Δ and ∇

buttons are pressed simultaneously the calibrated span will be used even though it is less than the recommended range.

YYRY

Command maximum saturated - Calibration error indicating that the 4-20 mA signal corresponding the
maximum command was too high. Adjust the signal a lower range and re-do the calibration. This error
may be cleared by brieﬂy pushing the quick-cal button, which will force the positioner to use the parameters
from the last good calibration.

YYGG

Calibration complete - Indicates that a 4-20 command calibration is complete. This pause allows the signal to be adjusted
without affecting the valve position. Press the

Δ and ∇ buttons simultaneously to put the unit back in operation.

YRRR

Feedback span - The range of motion of the position feedback arm was too small. Check for loose linkages and/or
adjust the feedback pin to a position closer to the follower arm pivot to create a larger angle of rotation. Also check
the air supply to make sure the system is properly connected. This error may be cleared by brieﬂy pushing the
quick-cal button, which will force the positioner to use the parameters from the last good calibration or if the
Δ and ∇ buttons are pressed simultaneously the calibrated span will be used even though it is less than the
recommended range.

YRRY

Feedback 100 saturated - Calibration error indicating that the position sensor was out of range during the
calibration. To correct the condition, adjust the positioner mounting, linkage or feedback potentiometer to move
the position sensor back into range then restart the calibration. This error may be cleared by brieﬂy pushing
the quick-cal button, which will force the positioner to use the parameters from the last good calibration.

YRRG

Waiting for 100% position JOG set point from User - only used during Jog calibration see explanation in
Quick-Cal section of main document for operation.

YRYY

Feedback no-motion during calibration - Indicates that there was no motion of the actuator based on the
current stroke time conﬁguration. Check linkages and air supply to make sure the system is properly
connected. If the time out occurred because the actuator is very large then simply retry the Quick cal and
the positioner will automatically adjust for a larger actuator by doubling the time allowed for movement.
This error may be cleared by brieﬂy pushing the quick-cal button, which will force the positioner to use the
parameters from the last good calibration.

YRYG

Setting IL offset (during Stroke calibration) - An automatic step in the calibration process that is done with
the valve a 50% position. This must be completed for proper operation.
