Responsibility for proper selection, use, and maintenance of any product remains solely with the purchaser and end user. Manula Used in this Manual. Manul Control Valve with cautions and warnings. Some of the procedures also contain the sequence of Introduction and Specifications Table Specifications Available Configurations Maximum: Rotary and long-stroke sliding-stem Medium: Air or Natural Gas applications [over mm 4 inch travel] Air: Supply pressure must be clean, dry air that DVC Quarter-turn rotary applications meets the requirements of ISA Standard 7.
Nitrile standard Linear Actuators with rated travel between 6. If using natural gas as the plastic cover when flammable gases pneumatic supply medium, natural gas will be used in or dust are present, do not rub or the pneumatic output connections of the DVC to clean the cover with solvents. Always refer to the nameplate itself to and B-7 for FM loop schematics, and figures B-2 and identify the appropriate certification. B-9 for ,anual FM nameplates. DVC Digital Valve Controllers Note Note When dvc60000 the following steps, Do not use the stainless steel ensure there is enough clearance DVCS in high vibration service between the adjustment arm and the where the mounting bracket uses feedback arm to prevent interference standoffs spacers to mqnual to the with the bias spring.
If required, attach the spacer to the actuator shaft. Note Refer to figures and Refer to the following guidelines when mounting on manaul actuators with up to 4 fvc6000 of travel. Where a key number is referenced, figure Install the external lock washer on the adjustment installations use the long feedback arm [62 mamual 2. Position the adjustment arm in the slot of the inches from roller to pivot point].
Installations on connector arm and loosely install the flanged hex nut. If necessary, reposition the cam to attain alignment. Attach the travel indicator, to the shaft connector or spacer as described in the mounting kit instructions.
Attach the mounting bracket to the remote feedback unit. ValveLink software and the Field 7. Position the remote feedback unit so that the pin on Communicator use the convention of the travel indicator, engages the slot in the feedback clockwise figure and Contact your Supply and output pressure gauges may be supplied Emerson Process Management sales office for on the digital valve controller.
The output pressure information on obtaining a Natural Gas Certified, gauges can be used as an aid for calibration. Installation Output Connections A factory mounted digital valve controller has its output piped to the pneumatic input connection on amnual actuator. Install a pipe plug in the vent-away into the surrounding atmosphere.
Connect one wire of the 3-conductor shielded cable between terminal 1 on the feedback unit and terminal D Emerson Process Management supplied 1 on the base unit. Connect the second wire of the 3-conductor Connect the second wire of the 3-conductor shielded cable between the middle lead wiper of the 10 kOhm potentiometer to Terminal 2 on the base unit.

Burst cable length, select a wire with lower capacitance per Command 3. In burst mode, the digital valve controller foot.
Each burst message contains the latest value of the primary analog inputsecondary 1. Changes to the instrument setup may To view the instrument mode, press the Hot Key and cause changes in the output pressure select Instrument Mode.
Basic Setup Communicator sets the setup parameters to the Table Factory Default Settings values listed in table If you select NO for the Setup Parameter Default Setting factory defaults, the setup parameters manuall in the Analog Input Units table remain at their previous settings.
For additional information on using the Performance Tuner, refer to Using the Performance Tuner in this section. Front Cover Detailed Setup. Factory Default Detailed Setup Parameters continued Enabling burst mode provides continuous Default Setup Parameter communication from the digital valve controller.
Burst Setting mode applies only to the transmission of burst mode Instrument Time Invalid Enable data analog input, travel target, pressure, and travel Calibration in Progress Enable and does not affect the way other data is accessed.
Detailed Setup Table The Performance Tuner is used to optimize digital valve controller tuning. See Depends upon pneumatic connections. During operation, the travel target will instrument is set up for position or pressure control.
Because the digital valve controller is constantly in control and not allowed to reach a dormant or saturated state, it is constantly testing its own pneumatic system. If there is an output pressure deviation, for example, the instrument will issue an alert. A value of 0. Detailed Setup Sensor Alerts point, the supply pressure alert is active.
