SIGNATURE OR PARTIAL STROKE TEST IN PROGRESS

Description: The positioner is in Out Of Service (OOS) mode
because a test or signature has been initiated. These
include Step Test, Ramp Test, or Partial Stroke Test.

Possible Solutions: Signatures and tests can be defined,
initiated, and cancelled through the Off-Line Diagnostics
pages of the DTM.

GRGY

STROKE CALIBRATION IN PROGRESS
SETTING INNER LOOP OFFSET
PRESSURE CALIBRATION IN PROGRESS
FRICTION CALIBRATION IN PROGRESS
ANALOG OUTPUT CALIBRATION IN PROGRESS
COMMAND INPUT CALIBRATION IN PROGRESS

Description: A calibration sequence is in progress. The inner
loop offset is an important step of the stroke calibration.

Possible Solutions: The calibration can be canceled from the
corresponding calibration page of the DTM, from the
handheld, or by briefly pressing the BACK button.

GRGR

DI COMMAND OVERRIDE

Description: The Multi-Function Card has been configured as
a Discrete Input (DI) and to override the input command,
positioning the valve at a preconfigured set point. The DI
signal is active and the positioner is attempting to control the
valve at the set point.

Possible Solutions: Configure the DI function and set point
using the menu, a handheld or the Multi-Function Card
Configuration page of the DTM.

JOG COMMAND MODE

Description: The positioner has been placed in a local
override mode where the valve can only be stroked using the
UP and DOWN buttons. The positioner will not respond to
analog or digital input commands from HART.

Possible Solutions: Control the valve using the UP and
DOWN buttons. This mode may be cancelled by briefly
pushing the QUICK-CAL/ACCEPT button.

JOG CALIBRATION SET 100% POSITION

Description: During a jog calibration, the unit is waiting for the
user to manually adjust the valve position to the desired
100% open position.

Possible Solutions: Use the Up and Down buttons on the
positioner to adjust the valve to the desired fully open
position. The QUICK-CAL/ACCEPT button to accept.

POSITION HIGH LIMIT ALERT
POSITION LOW LIMIT ALERT

Description: The position has reached or is exceeding a user
defined position limit. This is similar to a limit switch
indicator.

Possible Solutions: Set the limit to a higher (or lower) value if
more travel is needed, or adjust the command signal back in
the specified range.

ACTUATOR CYCLES WARNING
ACTUATOR TRAVEL WARNING
BELLOWS CYCLES WARNING
BELLOWS TRAVEL WARNING
PILOT RELAY CYCLES WARNING
PILOT RELAY TRAVEL WARNING
VALVE CYCLES WARNING
VALVE TRAVEL WARNING

Description: The cycle or travel limit of the valve, actuator,
bellows or pilot relay has been exceeded. Each cycle
represents two reversals of the direction of valve movement.
The cycle counting criterion and count limit (for the valve,
actuator and bellows) are set by the user to track the usage
of the valve assembly.

Possible Solutions: Follow routine procedures for
maintenance when the limit is reached. For example valve
inspection may include checking the packing tightness, and
checking linkages for wear, misalignment, and tightness.
Bellows inspection may include checking bellows for cracking
or leaking. Actuator inspection may include checking the
actuator seals and lubrication. Relay inspection may include
checking for high air consumption and signs of wear on the
spool. After maintenance, reset the travel accumulator.

POSITION AMPLITUDE WARNING
POSITION FREQUENCY WARNING

Description: The amplitude or frequency of the position signal
is above the warning limit. The positioner is controlling the
position of the valve with large or rapid corrections.

Possible Solutions: Verify the limits are set at an appropriate
level. Adjust the selectable Gain switch to a lower setting or
use the Hi Friction setting. Perform a QUICK-CAL which
sets the gains based on valve response. Check for high
friction. If the problem persists replace the relay.

YGYR

COMMAND AMPLITUDE WARNING
COMMAND FREQUENCY WARNING

Description: The amplitude or frequency of the command
signal is above the warning limit. This could mean the
control loop has larger swings or is oscillating faster than
desirable.

Possible Solutions: Verify the limits are set at an appropriate
level. Review the control loop parameters and equipment.
Adjust as necessary.

YGRY

CONTINUOUS STROKE TEST FAILED WARNING

Description: During the continuous stroke test, the valve did
not move after 5 consecutive attempts. This could mean the
valve has increased friction, a change in process load or
inadequate supply pressure.
