Troubleshooting
If communication or output difficulties are experienced with the instrument, refer to the troubleshooting chart in
table 6‐4. Also see the DVC6000 HW2 Troubleshooting Checklist on page 83.
Checking Voltage Available
WARNING
Personal injury or property damage caused by fire or explosion may occur if this test is attempted in an area which contains
a potentially explosive atmosphere or has been classified as hazardous.
To check the Voltage Available at the instrument, perform the following:
1. Connect the equipment in figure 2‐3 to the field wiring in place of the FIELDVUE instrument.
2. Set the control system to provide maximum output current.
3. Set the resistance of the 1 kilohm potentiometer shown in figure 2‐3 to zero.
4. Record the current shown on the milliammeter.
5. Adjust the resistance of the 1 kilohm potentiometer until the voltage read on the voltmeter is 10.0 volts.
6. Record the current shown on the milliammeter.
7. If the current recorded in step 6 is the same as that recorded in step 4 (± 0.08 mA), the voltage available is
adequate.
8. If the voltage available is inadequate, refer to Section 2, Wiring Practices.
Restart Processor
This is a “soft” reset of the device. This procedure can only be performed while the instrument is out of service. A soft
reset will immediately put into effect changes that have been sent to the instrument. Also, if the device is configured
to shutdown on an alert, the soft reset will clear the shutdown.
