Alert Record Setup for a Fisher™FIELDVUE™
DVC6200 HW2 Digital Valve Controller
Alert Record in the DVC6200 HW2 is accessible using ValveLink™software or DD based communications such as a Trex
Device Communicator or AMS Device Manager, and can be configured to record and time stamp alert conditions.
Twenty (20) alert records may be stored in the instrument. The alert record is a great troubleshooting tool when used
properly.
Note
The alert record does not use a first in first out (FIFO) operation. Once the alert record is full, the instrument will not record
additional events until the alert record is cleared. Alerts will continue to be reported to the control or asset management system.
Enable the Alert Record
1. The alert record in the DVC6200 is disabled by default. It is good practice to enable the alert record and clear it after
startup procedures are complete; when the alert record is enabled during start-up it can be filled with irrelevant
alerts.
2. To enable the alert record, open the Detailed Setup menu using the Block icon.
3. Click on Alert Record ( ) at the top of the Detailed Setup window.
4. Verify that Alert Record Enable is set to yes.
a. Use the drop down menu on the right to change values as needed.
b. Use the left arrow next to the parameter to download the value to the instrument.
Set Alert Record Not Empty and Alert Record Full Alerts
Enabling both of these alerts will generate an alert in Status Monitor when alert values are recorded and available to
view in the Alert Record.

Set Instrument Clock
The initial clock value shown in the right column is the computer time when the Alert Record page is opened.
1. Adjust the time value as needed.
2. Use the left arrow to download the time and date to the instrument.
Note
The instrument time will reset to the default value any time power is cycled to the instrument; set the instrument clock as the last
step when commissioning the instrument in a control loop.
If the instrument clock resets unexpectedly, it may indicate intermittent power cycle issues are occurring, such as I/O channel
cycling on/off or a bad wire connection.
Configure Key Alerts:
1. Enable the alerts you want to monitor using the Detailed Setup menu.
2. Key alerts to enable include:
a. Travel Deviation – Travel Alerts Tab
D Adjust the Alert Point and Time for the actuator size.
b. Supply Pressure Low – Pressure Alerts Tab
D Set Alert Point to just below the upper bench set pressure or the minimal pressure required to move a piston.
c. Drive Signal – Electronic Alerts tab
D Drive signal is typically between 60 and 80% when the valve is not on a stop. It is used to determine how hard
the digital valve controller is working to maintain the position of the valve.

d. Diagnostic Data Available – Informational Status Tab
D This alert indicates PD trigger information is stored in the instrument buffer.
e. Pressure Fallback Active – Sensor Alerts Tab

- Pressure Fallback must be enabled
View and Clear Stored Alert Records
1. Connect to the DVC6200 with ValveLink software.
2. Select Instrument Alert Record from the Diagnostics drop down menu.

3. Use the next and previous arrows to scroll through the records. Each record may contain multiple alerts depending
on what was active at the time the record was captured.
Note:
The alert record list cannot be downloaded.
Note:
Instrument time is shown as Approximate in the image above because the instrument clock was not reset following a power cycle.
4. When finished viewing records click on Clear Instrument Alert Record to erase all current records and allow for 20
new records to be recorded.
Note
Best practice is to set the instrument clock and clear the alert record after the DVC6200 is connected to the control system and
final commissioning steps have been performed.

View Active Alerts
Active alerts may be reported via HART protocol to a control or asset management system. They are also viewable
using ValveLink Status Monitor. The image below shows active alerts in ValveLink software reported while the Status
Monitor is running; this alert information is also recorded in the instrument.
Note
The alert monitor can run in a live process and passively monitor instrument parameters.
