DVC2000 Digital Valve Controller

Once switch circuit 1 is powered properly, question marks (???) will indicate that the corresponding switch is disabled.
Shutdown Activated— This screen appears if the positioner has shut down and no air is being delivered to the actuator.
Therefore, the valve is at its fail‐safe position. An example of a source of this error is corrupt firmware code upon
start‐up. The factory default setting for this error is disabled. Therefore, this alert will only be enabled by actively
configuring it with a HART based host (e.g. Field Communicator, ValveLink Software).
Travel Deviation— This error message indicates that there is a difference between the input signal (after
characterization) and the actuator travel reading from the position feedback element. The default setting is 7% for 5
seconds. These settings can be configured through a HART communicating host on any instrument HC tier or higher.
Possible sources of this error are insufficient air supply or excessive valve friction.
Replace Main Board— A problem with the electronics has been detected. Sources of this error may include hardware or
firmware problems. If this error is detected, the instrument may be operational, but performance will be degraded.
Check Mounting— The valve position feedback reading is valid, but it is outside the operating range. Sources of this
error include loose or bent mounting brackets or a misaligned magnet array. This error does not identify faulty
components, but rather faulty installation or alignment. This alert is also called a Travel Sensor Failure.
Check Supply— The valve is not able to reach its target position due to insufficient supply pressure. This error will most
likely occur in conjunction with the Travel Deviation error.
Check I/P Converter— A problem relating to the I/P converter has been detected. Sources of this error include:
D Electronics problems indicated by the drive current read back being out of range
D Low supply pressure indicated by an active drive signal alert
D A stuck valve resulting in integrator wind‐up.
Device Locked by HART— Another HART host (e.g. ValveLink software, AMS Suite: Intelligent Device Manager, or the
Field Communicator) is communicating with the DVC2000. Typically this means that the instrument is "out of
service". In devices with firmware version 3 or later, you can clear this message by holding down the left button while
cycling power to the DVC2000. This will place the instrument back "in service."
FIELDVUE Instruments—This is displayed when there are no languages loaded on the DVC2000. This could occur
during firmware download.
Pressure = ???—The actuator pressure reading is greater than 125% of the configured maximum supply pressure. For
example, if the supply pressure range was set to 35 psi and the actual supply pressure was 45 psi, you will see ???'s
when the DVC2000 is delivering full supply pressure to the actuator. If you reduce the supply pressure, or stroke the
valve closed (air‐to‐open/fail closed setup), eventually there will be a point where numerical values appear.
This configuration parameter can be changed through the Field Communicator (1‐1‐2‐2‐3) or ValveLink software
(Detailed Setup > Pressure).
