Command Input Set 0%
A Command Input Calibration has
been started using the buttons (not
LCD) and the positioner is waiting for
the user to adjust the loop current to
0% and press the QUICK-CAL button
to accept.
Complete the calibration.
Command Input Set 100%
A Command Input Calibration has
been started using the buttons (not
LCD) and the positioner is waiting for
the user to adjust the loop current to
100% and press the QUICK-CAL
button to accept.
Complete the calibration.
Command Amplitude
Alarm
The amplitude of the command signal
is above the alarm limit. This could
mean the control loop has larger
swings than desirable.
Verify the limits are set at an
appropriate level. Review the
control loop parameters and
equipment. Adjust as necessary.
Command Amplitude
Warning
The amplitude of the command signal
is above the warning limit. This could
mean the control loop has larger
swings than desirable.
Verify the limits are set at an
appropriate level. Review the
control loop parameters and
equipment. Adjust as necessary.
Command Frequency
Alarm
The frequency of the command signal
is above the alarm limit. This could
mean the control loop is oscillating
faster than normal.
Verify the limits are set at an
appropriate level. Review the
control loop parameters and
equipment. Adjust as necessary.
Command Frequency
Warning
The frequency of the command signal
is above the warning limit. This could
mean the control loop is oscillating
faster than normal.
Verify the limits are set at an
appropriate level. Review the
control loop parameters and
equipment. Adjust as necessary.
Command Input Above
ADC Range
During Command Loop Calibration, the
100% signal was out of the Analog to
Digital Converter (ADC) range.
Replace the electronics assembly.
Command Input Below
ADC Range
During Command Loop Calibration, the
0% signal was out of the Analog to
Digital Converter (ADC) range.
Replace the electronics assembly.
Command Input
Calibration in Progress
The command input calibration
sequence is in progress.
The calibration can be canceled
from the Command Calibration
page of the DTM, from the
handheld, or by briefly pressing all
three buttons at once.
Command Input Range
Too Small
During a Command Loop Calibration,
the difference between the signal at
0% and the signal at 100% was too
small. The system is designed to
accept a difference greater than 5 mA.
Recalibrate making sure to use a
larger difference between command
signal limits. The difference must
exceed 5 mA.
CPU Usage Warning
The CPU usage is too high.
Update the firmware.
DI Active Alert
The voltage to the DI has changed,
triggering an action defined by the
user.
No action is required. The function
of the DI can be set in the DTM,
using a handheld, or from the LCD
menu.
DI Command Override
The a Discrete Input (DI) has been
configured 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.
Configure the DI function and set
point using the menu, a handheld or
the Configuration page of the DTM.
