GGGG
NORMAL OPERATION indicates normal, healthy operation
GGGY
MPC ACTIVE MODE (user set) indicates that tight shutoff (MPC)
is active. The command is beyond the user set limit for tight
shutoff feature. This is a normal condition for all valves when
closed. The factory default setting triggers this at command si-
gnals below 1%. This indication may also occur on 3 way valves
at both ends of travel if the high MPC value has been set.
If tight shutoff is not desired reset the tight shutoff limits to the correct
values or adjust the command signal inside of the specifi ed MPC value.
See DTM screen: Confi guration/Custom/Position Cutoff.
GGYG
LOCAL INTERFACE DISABLED/ENABLED when DISABLED, in-
dicates PC software has been used to disable the local interface.
This code is only present for a short time when the Quick Cal
button is pressed.
If local control is desired then the local interface must be re-enabled
from the remote software. See DTM screen: Confi guration/Basic Local
Interface.
GGYY
DIGITAL COMMAND SOURCE indicates a HART signal is needed
to change the position command and the analog 4-20 mA input
signal is ignored.
A manual Command Source Reset is provided to change the command
back to analog control mode from the local interface if a PC or hand-held
confi gurator is not available. This is done while a QUICK-CAL is in pro-
gress by holding down both the Jog buttons (up and down) while briefl y
pressing the QUICK-CAL button. A new QUICK-CAL must be done after
resetting. See DTM screen: Dashboard.
GGRR
SQUAWK MODE ON/OFF (user set) When ON, this indicates a
user has set the positioner to fl ash a special sequence so that it
can be visually located.
This mode is canceled if the QUICK-CAL button is briefl y pressed, the
Squawk mode is selected again remotely, or more than one hour has
passed since the command was issued. See DTM screen: Confi guration/
Custom/LED.
GYGG
POSITION LIMIT ALERT (user set) indicates the position has
reached or is exceeding a user defi ned upper or lower position
indicator similar to a limit switch indicator.
Reset the indicator if more travel is needed or adjust the command signal
back in the specifi ed range. See DTM screen: Confi guration/Custom/
Position Cutoff. This indicator can be disabled.
GYGY
SOFT STOP LIMIT ALERT (user set) indicates the unit is being
commanded to exceed a user defi ned upper or lower position
limit and the internal software is holding the position at the limit.
The function is similar to a mechanical limit stop except it is not
active if the unit is un-powered.
Reset the limit if more travel is needed or adjust the command signal
back in the specifi ed range. See DTM screen: Confi guration/Custom/Soft
Limits.
GRGG
CYCLES or TRAVEL LIMIT ALERT (user set) indicates that one of
the cycle or travel limits has been exceeded. The criterion and
count limit are set by the user to track the usage of the valve.
There are accumulators for total valve travel, total valve cycles,
total spool valve travel, and total spool valve cycles. Flowserve
supplied software can identify the specifi c limit that has been
reached.
For valve accumulators indications follow routine procedures for
maintenance when the limit is reached such as checking the packing
tightness, and checking linkages for wear, misalignment, and tightness.
After maintenance, reset the cycle accumulator. See DTM screen: Health
Status/Positioner Health. This indicator can be disabled. For spool valve
accumulators inspect for high air consumption and signs of wear. See
DTM screen: Health Status/Positioner Health. This indicator can be
disabled.
YGGY
SIGNATURE IN PROGRESS MODE indicates that a test has been
initiated by Flowserve supplied software
Signatures can only be canceled by Flowserve supplied software. See
DTM screen: Diagnostics.
YGGR
INITIALIZING MODE displays a blink sequence 3 times when the
unit is powering up.
Wait for power up to complete.
YGYG
CALIBRATION IS IN PROGRESS indicates a calibration is pro-
cess. Calibrations such as stroke may be initiated locally with
the QUICK-CAL button or remotely. Other calibrations for the in-
puts and outputs or pressure sensors are only initiated remotely.
Local calibration may be canceled by briefl y pushing the QUICK-CAL
button. Remote calibrations can only be canceled by the software.
YGYY
JOG COMMAND STATE indicates the unit has been placed in a
local override mode where the valve can only be stroked using
the two local jog buttons.
Control the valve using the jog buttons. This mode may be canceled by
briefl y pushing the QUICK-CAL button.
YGYR
JOG CALIBRATION STATE indicates that during a jog calibration,
the unit is waiting for the user to manually adjust the valve positi-
on to the desired 100% open position.
Use the buttons on the positioner to adjust the valve to the desired fully
open position. See the explanation of Jog Calibrate in the QUICK-CAL
section of main document for operation.
YYGG
POSITIONER TEMPERATURE WARNING (user set) indicates the
internal electronics have exceeded a temperature limit. The mini-
mum limit of the electronics and the default setting is -40°F (-40°C).
Low temperature may inhibit responsiveness and accuracy. The
maximum limit of the electronics and default setting is 185°F (85°C).
High temperature may limit the life of the positioner.
Regulate the temperature of the positioner. If the temperature reading is
in error, replace the main board. See DTM screen: Health Status/Positio-
ner Health. This indicator can be disabled.
YYGY
PRESSURE OUT OF RANGE WARNING indicates that during a
pressure sensor calibration, the range of applied pressures to
port 1 was too small for optimum performance.
Adjust the supply pressure to a proper value (30-150 psig) so the positio-
ner can properly calibrate the sensors. Then recalibrate. Briefl y push the
QUICK-CAL button to acknowledge this condition and the positioner will
operate using the current short stroke calibration values if valid.
