Description

DVC6200 SIS digital valve controllers (figure 1‐1) are HART communicating, microprocessorbased currenttopneumatic instruments. The DVC6200 SIS digital valve controller has three fundamental functions.

1. Modulate a pneumatic output to a valve actuator in response to a demand signal from a logic solver to move the valve to a safe state.

2. Perform periodic tests on a valve assembly to exercise the mechanical components that are prone to sticking.

3. Continuously monitor the health of the valve and report alerts.

Logic Solver or Control System Requirements

There are several parameters that should be checked to ensure the logic solver or control system is compatible with the DVC6200 SIS digital valve controller.

HART Filter / Line Conditioner

Depending on the logic solver or control system and operational mode of the DVC6200 SIS digital valve controller, a line conditioner or HART filter may be required.

Operational Mode

4-20 mA

Point-to-Point Loop

All No Yes

HART Filter

Required?

No No

Line Conditioner

Required?

The HF340 HART filter and LC340 Line Conditioner are passive devices that are inserted in the field wiring of the HART loop. A filter or line conditioner is normally installed near the field wiring terminals of the system I/O (see figure 2‐1). Its purpose is to effectively isolate the system output from modulated HART communication signals and raise the impedance of the system to allow HART communication. For more information, refer to the HF340 HART filter (D102796X012

) or LC340 Line Conditioner (D102797X012) instruction manual.

Voltage Available

The voltage available at the DVC6200 SIS digital valve controller must be at least 10 VDC. The voltage available at the instrument is not the actual voltage measured at the instrument when the instrument is connected. The voltage measured at the instrument is limited by the instrument and is typically less than the voltage available.

As shown in figure 2‐1, the voltage available at the instrument depends upon:

D The logic solver or control system compliance voltage

D if a line conditioner filter or intrinsic safety barrier is used, and

D the wire type and length.

The compliance voltage is the maximum voltage at the logic solver or control system output terminals at which the system can produce maximum loop current.

The voltage available at the instrument may be calculated from the following equation:

Voltage Available = [Compliance Voltage (at maximum current)] - [line conditioner/filter voltage drop] - [total cable resistance  maximum current] - [barrier resistance x maximum current].

The calculated voltage available should be greater than or equal to 10 volts DC.

COMPLIANCE VOLTAGE

CONTROL SYSTEM

LINE CONDITIONER OR HART FILTER (if used)

INTRINSIC SAFETY BARRIER (if used)

Calculate Voltage Available at the Instrument as follows:

Logic solver or control system compliance voltage

– Line conditioner or filter voltage drop (if used)

TOTAL LOOP CABLE RESISTANCE

Example Calculation

18.5 volts (at 21.05 mA for Honeywell TDC2000)

– 2 volts

VOLTAGE AVAILABLE AT THE

INSTRUMENT

– Intrinsic safety barrier resistance (if used) x maximum loop current – 2.55 volts (121 ohms x 0.02105 amps)

– Total loop cable resistance x maximum loop current

= Voltage available at the instrument

– 1.01 volts (48 ohms x 0.02105 amps for 1000 feet of Belden 9501 cable)

= 15.49 volts, available—if safety barrier (2.55 volts) is not used

NOTES:

Obtain filter voltage drop. The measured drop will be different than this value. The measured filter voltage drop

depends upon control system output voltage, the intrinsic safety barrier (if used), and the instrument. See note 2.

The voltage available at the instrument is not the voltage measured at the instrument terminals. Once the instrument is

connected, the instrument limits the measured voltage to approximately 8.0 to 9.5 volts.

Compliance Voltage

If the compliance voltage of the logic solver or control system is not known, perform the following compliance voltage test.

1. Disconnect the field wiring from the system and connect equipment as shown in figure 2‐2 to the system terminals.

2. Set the system to provide maximum output current.

3. Increase the resistance of the 1 kW potentiometer, shown in figure 2‐2, until the current observed on the milliammeter begins to drop quickly.

4. Record the voltage shown on the voltmeter. This is the compliance voltage.

Maximum Cable Capacitance

The maximum cable length for HART communication is limited by the characteristic capacitance of the cable. Maximum length due to capacitance can be calculated using the following formulas:

Length(ft) = [160,000 - C

Length(m) = [160,000 - C

where:

160,000 = a constant derived for FIELDVUE instruments to ensure that the HART network RC time constant will be no greater than 65 μs (per the HART specification).

= the capacitance of the control system or HART filter

master

= the capacitance of the cable used (see table 2‐1)

cable

The following example shows how to calculate the cable length for a Foxboro of 50, 000 pF and a Belden 9501 cable with characteristic capacitance of 50pF/ft.

Length(ft) = [160,000 - 50,000pF]  [50pF/ft]

Length = 2200 ft.

The HART communication cable length is limited by the cable characteristic capacitance. To increase cable length, select a wire with lower capacitance per foot. Contact your Emerson sales office for specific information relating to your control system.

Auxiliary Terminal Wiring Length Guidelines

The Auxiliary Input Terminals of a DVC6200 SIS can be used with an LCP100 local control panel or a locally‐mounted switch for initiating a partial stroke test. Some applications require that the switch or local control panel be installed remotely from the DVC6200 SIS.

The length for wiring connected to the Auxiliary Input Terminals is limited by capacitance. For proper operation of the Auxiliary Input Terminals capacitance should not exceed 100,000 pF. As with all control signal wiring, good wiring practices should be observed to minimize adverse effect of electrical noise on the Aux Switch function.

Example Calculation: Capacitance per foot or per meter is required to calculate the length of wire that may be connected to the Aux switch input. The wire should not exceed the capacitance limit of 100,000 pF. Typically the wire manufacturer supplies a data sheet which provides all of the electrical properties of the wire. The pertinent parameter is the highest possible capacitance. If shielded wire is used, the appropriate number is the “Conductor to Other Conductor & Shield” value.

Example — 18AWG Unshielded Audio, Control and Instrumentation Cable

Manufacturer's specifications include:

Nom. Capacitance Conductor to Conductor @ 1 KHz: 26 pF/ft Nom. Conductor DC Resistance @ 20 Deg. C: 5.96 Ohms/1000 ft Max. Operating Voltage - UL 200 V RMS (PLTC, CMG),150 V RMS (ITC) Allowable Length with this cable = 100,000pF /(26pF/ft) =3846 ft

Example — 18AWG Shielded Audio, Control and Instrumentation Cable

Manufacturer's specifications include:

Nom. Characteristic Impedance: 29 Ohms Nom. Inductance: .15 μH/ft Nom. Capacitance Conductor to Conductor @ 1 KHz: 51 pF/ft Nom. Cap. Cond. to other Cond. & Shield @ 1 KHz 97 pF/ft Allowable Length with this cable = 100,000pF /(97pF/ft) = 1030 ft

The AUX switch input passes less than 1 mA through the switch contacts, and uses less than 5 V, therefore, neither the resistance nor the voltage rating of the cable are critical. Ensure that switch contact corrosion is prevented. It is generally advisable that the switch have gold‐plated or sealed contacts.

Local Control Panel

Fisher LCP100 and LCP200 local control panels are used to manually open and close a safety shutdown valve.

The LCP100 provides a manual reset feature as well as a button for initiating a partial stroke test.

The LCP200 can be configured to auto or manual reset after a trip. It also offers a smart auto reset configuration which requires a manual reset for locally initiated trips but auto reset for all other trips. It includes trip and reset push buttons to provide a corresponding change in the state of the associated single pole double throw (SPDT) relay. The trip and reset relays can be used as input to initiate Trip or Reset action in the logic solver. Additionally, it includes a button for initiating a partial stroke test.

Installation

Both LCP100 and LCP200 local control panels have mounting holes for on‐site mounting of the device.

Notes

A mounting kit is available to use when replacing an LCP100 with the LCP200. Contact your Emerson sales office obtaining this kit.

The local control panel must be installed so that the wiring connections are on the bottom to prevent accumulation of moisture inside the box.

LCP100: When installing the LCP100 cover tighten the screws evenly in a criss‐cross pattern to a torque of 2.8 N•m (25 lbf•in) to help ensure the cover is properly installed.

LCP200: When installing the terminal cover on the LCP200, use a 4 mm hex key to tighten the screws evenly in a criss‐cross pattern to a torque of 8.7 N•m (77 lbf•in) +/- 10%, to help ensure the cover is properly installed. Apply silicone lubricant to the terminal box O-ring.

Guided Setup

Device Communicator Configure > Guided Setup (2‐1)

To quickly setup the instrument, the following procedures will guide you through the process.

Device Setup is used to configure the unique parameters for the valve, actuator, instrument and accessory construction. After Device Setup is complete, proceed with Auto Calibration.

Auto Calibration is used to establish the limits of physical travel. During this process, the valve will fully stroke from one travel extreme to the other. There are three calibration options to choose from:

d Autocalibrate – Standard runs the full calibration process (recommended). d Autocalibrate – Without Biases establishes the travel end points, but does not adjust the Minor Loop Feedback

bias. This is for advanced use when manually setting the biases for large actuators.

d Advanced Settings allows additional custom configuration of calibration parameters. This is for advanced use

when calibrating large actuators.

Manual Setup33

Manual Setup allows you to configure the digital valve controller to your application. Table 3‐1 lists the default settings

for a standard factory configuration. You can adjust actuator response, set the various modes, alerts, ranges, travel cutoffs and limits. You can also restart the instrument and set the protection.

Refer to table 3‐2 for possible configurations for a digital valve controller operated by a 4‐20 mA input current (point‐to‐point mode), and table 3‐3 for possible configurations for a digital valve controller operated by a 0‐24 VDC power supply (multi‐drop mode).

Instrument Mode

There are two instrument modes for the DVC6200 SIS; In Service or Out of Service. In Service is the normal operating mode such that the instrument follows the 420 mA or 24 VDC control signal. Out of Service is required in some cases to modify configuration parameters, calibrate, or to run diagnostics.

Note

Some changes that require the instrument to be taken Out Of Service will not take effect until the instrument is placed back In Service or the instrument is restarted.

Write Protection

There are two Write Protection modes for the DVC6200 SIS: Not Protected or Protected. Protected prevents configuration and calibration changes to the instrument. The default setting is Not Protected. Write Protection can be changed to Protected remotely. However, to change Write Protection to Not Protected, you must have physical access to the instrument. The procedure will require you to press a button ( ) on the terminal box as a security measure.

Instrument

Device Communicator Configure > Manual Setup > Instrument (2‐2‐2)

Follow the prompts on the Device Communicator display to configure the following Instrument parameters:

Identification

D HART Tag—A tag name up to 8 characters is available for the instrument. The HART tag is the easiest way to

distinguish between instruments in a multi‐instrument environment. Use the HART tag to label instruments electronically according to the requirements of your application. The tag you assign is automatically displayed when the Device Communicator establishes contact with the digital valve controller at power‐up.

D HART Long Tag (HART Universal Revision 7 only)—A tag name up to 32 characters is available for the instrument.

D Description provides a separate electronic label allowing for additional instrument identification.

D Message—Enter any message with up to 32 characters. Message provides the most specific user‐defined means for

identifying individual instruments in multi‐instrument environments.

D Polling Address—If the digital valve controller is used in point‐to‐point operation, the Polling Address is 0. When

several devices are connected in the same loop, such as for split ranging, each device must be assigned a unique polling address. The Polling Address is set to a value between 0 and 63 for HART 7 and 0 and 15 for HART 5. To change the polling address the instrument must be Out Of Service. For the Device Communicator to be able to communicate with a device whose polling address is not 0, it must be configured to automatically search for all or specific connected devices.

Serial Numbers

D Instrument Serial Number—Enter the serial number on the instrument nameplate, up to 12 characters.

D Valve Serial Number—Enter the serial number for the valve in the application with up to 12 characters.

Units

D Pressure Units—Defines the output and supply pressure units in either psi, bar, kPa, or kg/cm2.

D Temperature Units—Degrees Fahrenheit or Celsius. The temperature measured is from a sensor mounted on the

digital valve controller's printed wiring board.

D Analog Input Units—Permits defining the Analog Input Units in mA or percent of 4-20 mA range.

Terminal Box

D Calibration (CAL) Button—This button is near the wiring terminals in the terminal box and provides a quick means to

autocalibrate the instrument. The button must be pressed for 3 to 10 seconds. Autocalibration will move the valve through the full range of travel whether the Instrument Mode is In Service or Out of Service. However, if the Write Protection is Protected, this button will not be active. To abort, press the button again for 1 second. The calibration button is disabled by default.

Configuration

June 2022

D Auxiliary Terminal Action—These wire terminals can be configured to initiate a partial stroke test upon detection of

a short across the (+) and (-) terminals. The terminals must be shorted for 3 to 10 seconds. Alternatively, the auxiliary terminals can be configured to support the local control panel.

Instruction Manual

D103557X012

Spec Sheet

The Spec Sheet provides a means to store the entire control valve specifications on board the DVC6200 SIS.

Edit Instrument Time

Permits setting the instrument clock. When alerts are stored in the alert record, the record includes the time and date. The instrument clock uses a 24‐hour format.

Travel/Pressure Control

Device Communicator Configure > Manual Setup > Travel/Pressure Control (2‐2-3)

End Point Pressure Control (EPPC)

D EPPC Enable—Select Yes or No. End Point Pressure Control allows the digital valve controller to pull back from

saturation of the pneumatic output after reaching the travel extreme. Rather than having the instrument provide full supply pressure (saturation) continuously at the travel extreme, the digital valve controller switches to an End Point Pressure Control where the output pressure (pressure controller set point) to the actuator is maintained at the EPPC Set Point. Because the digital valve controller is actively controlling the pressure 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. To ensure there is an alert when an output pressure deviation occurs, setup the alert as described under Pressure Deviation Alert.

D EPPC Set Point—Used in conjunction with End Point Pressure Control, End Point Pressure Control Set Point allows

the user to select a pressure to be delivered by the instrument at the travel extreme. For a fail‐closed valve, this pressure must be sufficient to maintain the fully open position. For a fail‐open valve, this pressure (which is automatically set to supply pressure) must be sufficient to fully close the valve and maintain its rated shutoff classification. For double‐acting spring return actuators, this is the differential pressure required to either maintain the fully open or fully closed position, depending on the valve and actuator configuration. For a double‐acting actuator without springs with a fail‐close valve, this is 95% of the supply pressure.

D EPPC Saturation Time—End Point Pressure Control Saturation Time is the time the digital valve controller stays in

hard cutoff before switching to pressure control. Default is 45 seconds.

D End Point Pressure Control Tuning— These are the tuning parameters that the instrument uses while in end point

pressure control. The tuning set letters correspond with the travel control tuning sets (e.g. if tuning set C is appropriate for travel control, it is also appropriate for pressure control). However, note that the individual values may be different between travel and pressure control.

Characterization

Input Characterization defines the relationship between the travel target and ranged set point. Ranged set point is the

input to the characterization function. If the zero power condition equals closed, then a set point of 0% corresponds to a ranged input of 0%. If the zero power condition equals open, a set point of 0% corresponds to a ranged input of 100%. Travel target is the output from the characterization function.

To select an input characterization, select Input Characterization from the Characterization menu. You can select from the three fixed input characteristics shown in figure 3‐1 or you can select a custom characteristic. Figure 3‐1 shows the relationship between the travel target and ranged set point for the fixed input characteristics, assuming the Zero Power Condition is configured as closed.

You can specify 21 points on a custom characteristic curve. Each point defines a travel target, in % of ranged travel, for a corresponding set point, in % of ranged set point. Set point values range from -6.25% to 106.25%. Before modification, the custom characteristic is linear.

Custom Characterization

To define a custom input character, from the Characterization menu select Custom Characterization. Select the point you wish to define (1 to 21), then enter the desired set point value. Press Enter then enter the desired travel target for the corresponding set point. When finished, select point 0 to return to the Characterization menu.

With input characterization you can modify the overall characteristic of the valve and instrument combination. Selecting an equal percentage, quick opening, or custom (other than the default of linear) input characteristic modifies the overall valve and instrument characteristic. However, if you select the linear input characteristic, the overall valve and instrument characteristic is the characteristic of the valve, which is determined by the valve trim (i.e., the plug or cage).

Instruction Manual

D103557X012

Dynamic Response

D SP Rate Open is the maximum rate (% of valve travel per second) at which the digital valve controller will move to

the open position regardless of the rate of input current change. A value of 0 will deactivate this feature and allow the valve to stroke open as fast as possible.

D SP Rate Close is the maximum rate (% of valve travel per second) at which the digital valve controller will move to

the close position regardless of the rate of input current change. A value of 0 will deactivate this feature and allow the valve to stroke close as fast as possible.

D Set Point Filter Time (Lag Time) slows the response of the digital valve controller. A value ranging from 0.2 to 10.0

can be used for noisy or fast processes to improve closed loop process control. Entering a value of 0.0 will deactivate the lag filter.

Travel Cutoffs

D Hi Cutoff Select—When selected the Travel Target is set to 123% when the Travel exceeds the Hi Cutoff Point.

D Hi Cutoff Point is the point within the calibrated travel range above which the cutoff is in effect. When using cutoffs,

a Cutoff Hi of 50% is recommended to ensure valve goes fully open.

D Lo Cutoff Select—When selected the Travel Target is set to 23% when the Travel is below the Lo Cutoff Point.

D Lo Cutoff Point is the point within the calibrated travel range below which the cutoff is in effect. When using cutoffs,

a Cutoff Lo of 50% is recommended to help ensure maximum shutoff seat loading.

WARNING

During Stabilize/Optimize the valve may move, causing process fluid or pressure to be released. To avoid personal injury and property damage caused by the release of process fluid or pressure, isolate the valve from the process and equalize pressure on both sides of the valve or bleed off the process fluid.

Stabilize/Optimize permits you to adjust valve response by changing the digital valve controller tuning. During this routine, the instrument must be out of service; however, the instrument will respond to setpoint changes.

If the valve is unstable select decrease response for a more conservative setting. If the valve response is sluggish, select increase response for a more aggressive setting. When finished select Done.

Use the Integral Dead Zone and Integrator Limit values automatically selected during setup for the DVC6200 SIS High Cv.

D Integral Dead Zone—A window around the Primary Setpoint in which integral action is disabled. This feature is used

to eliminate friction induced limit cycles around the Primary Setpoint when the integrator is active. The Dead Zone is configurable from 0% to 2%, corresponding to a symmetric window from 0% to +/-2% around the Primary Setpoint. Default value is 0.25%. Default value for the DVC6200 SIS High Cv is 0.75%.

D Integrator Limit—The Integrator Limit provides an upper limit to the integrator output. The high limit is configurable

from 0 to 100% of the I/P drive signal. Default value for the DVC6200 SIS High Cv 50%.

Feedback Connection—Refer to table 3‐8 for Feedback Connection options. Choose the assembly that matches the actuator travel range.

Note

As a general rule, do not use less than 60% of the magnet assembly travel range for full travel measurement. Performance will decrease as the assembly is increasingly subranged.

The linear magnet assemblies have a valid travel range indicated by arrows molded into the piece. This means that the hall sensor (on the back of the DVC6200 SIS housing) has to remain within this range throughout the entire valve travel. The linear magnet assemblies are symmetrical. Either end may be up.

Travel Sensor Motion

WARNING

If you answer YES to the prompt for permission to move the valve when determining travel sensor motion, the instrument will move the valve through a significant portion of its travel range. To avoid personal injury and property damage caused by the release of process fluid or pressure, isolate the valve from the process and equalize pressure on both sides of the valve or bleed off the process fluid.

Select Clockwise/Toward Bottom, or Counterclockwise/Toward Top. Travel Sensor Motion establishes the proper travel sensor rotation. For quarter‐turn actuators determine rotation by viewing the rotation of the magnet assembly from the back of the instrument.

Note

Travel Sensor Motion in this instance refers to the motion of the magnet assembly. Note that the magnet assembly may be referred to as a magnetic array in user interface tools.

D For instruments with Relay A or C, or direct-acting HCv1, HCv2, HCv3: If increasing air pressure at output A causes

the magnet assembly to move down or the rotary shaft to turn clockwise, enter CW/To Bottom Inst. If it causes the magnet assembly to move up, or the rotary shaft to turn counterclockwise, enter CCW/To Top Inst.

Maximum Supply Pressure

Enter the maximum supply pressure that is required to fully stroke the valve. For DVC6200 SIS High Cv the supply pressure must be between 2.8 bar (40 psig) and 10 bar (145 psig).

Port A Pressure Limit

In single acting direct only applications, the instrument will limit the output pressure to the actuator from Port A. When this pressure limit is exceeded the device will go to the no air state.

SIS/Partial Stroke Test

Device Communicator Configure > Manual Setup > SIS/Partial Stroke (2-2-6)

A partial stroke test is the process of taking the valve from the normal end to a target position at a preconfigured ramp rate before returning to the normal end while gathering data. The data is analyzed to evaluate the condition of the valve assembly against a set of user defined thresholds. A partial stroke test is only run if everything is normal in the instrument. A safety demand signal will always take precedence over a partial stroke test.

Partial Stroke Test Parameters

Test Start Point defines the normal (not tripped) end of valve travel. The valve must be at this end for a PST to be

initiated. Setting this value to Not Configured will disable partial stroke tests.

Travel Hi Hi defines, in percent (%) of calibrated travel, the point above which the valve is considered to have reached the high end.

Travel Lo Lo defines, in percent (%) of calibrated travel, the point below which the valve is considered to have reached the low end.

Pause Time is the time between the outgoing and incoming strokes of the test. The default value is 5 seconds. The outgoing stroke is from the normal end to the PST target and the incoming stroke is the return stroke to normal. See figure 3‐3.

Action On a Failed Test defines if the valve should step or ramp back on a failed stroke test.

Auto Test Interval is the interval of time in days between valve stroke tests that are automatically executed by the

digital valve controller, subject to the device being powered up. A value of 0 disables this feature.

Partial Stroke Parameters

Minimum Travel Movement is the percentage of total span that the valve moves away from its normal operating end

of travel towards its tripped end of travel during the test. The default value is 10%; default for DVC6200 SIS High Cv is 20%.

Outgoing Pressure Threshold defines the actuator pressure at which a partial stroke test will abort during the outgoing stroke (see figure 3‐3). This prevents the DVC6200 SIS from exhausting (or building) excessive pressure from/to the actuator in an attempt to move a stuck valve. During PST Calibration, the Partial Stroke Outgoing Pressure Threshold will be set automatically as follows:

d Single-Acting Actuators - For those actuators that exhaust pressure from the partial test start point, the Outgoing

Pressure Threshold will be a minimum value. For those actuators that build pressure from the partial test start point, the Outgoing Pressure Threshold will be a maximum value.

d Double-Acting Actuators - The Outgoing Pressure Threshold will be set to a negative value for actuators where the

partial stroke start point is opposite of the Zero Power Condition (e.g., Partial Stroke Start Point = Open and Zero Power Condition = Closed) and to a positive value for actuators where the partial stroke start point is the same as the Zero Power Condition.

The pressure signal used to determine this parameter depends on relay type and is summarized below.

Relay Type Pressure Signal

A or C Port A - Port B B Port B - Port A B Special App. Port B C Special App. Port A HCv1, HCv2, HCv3 (direct-acting) Port A HCv1, HCv2 (reverse-acting) Port B HCv1, HCv2 (double-acting) Port A - Port B

To manually set the partial stroke Outgoing Pressure Threshold, you must examine current partial stroke test results using ValveLink software. The following steps will guide you through the process:

1. Connect the DVC6200 SIS to a system running ValveLink software.

2. Disable Partial Stroke Outgoing Pressure Limit by ensuring it is not selected as an evaluation criteria for PST Abnormal.

3. Run a partial stroke test.

4. Select the Press/Time radio button on the partial stroke graph (refer to the example in figure 3‐5). If the actuator pressure starts high and moves low, find the minimum actuator pressure (Pmin). If the actuator pressure starts low and moves high, find the maximum actuator pressure (Pmax). Doubleacting actuators will display differential pressure. Use table 3‐9 to estimate the Outgoing Pressure Threshold.

5. Enable the previously disabled Outgoing Pressure Limit - calculate the value using table 3‐9.

SIS Options

D LoopInitiated PST, when this feature is enabled, the digital valve controller will run a partial stroke test if the loop

current is set to within +/0.5% of the PST trip point. The loop current must remain at that point for the duration of the test. To abort the test, the loop current must be returned to the normal or tripped current. This feature is disabled by default. This feature is not available when a local control panel is installed.

d PST Trip Point (ETT) is the point at which the loop current must be set to run a partial stroke test for

energizetotrip applications. This value is not configurable and is preset at 8 mA.

d PST Trip Point (DETT) is the point at which the loop current must be set to run a partial stroke test for

deenergizetotrip applications. This value is not configurable and is preset at 16 mA.

D Latch on Position Trip— The device will take the output to the trip state if the loop current is normal and the travel

crosses the threshold towards the trip end. The position latch reset is always manual reset. The latch can be cleared by using one of the the user interfaces, a local control panel, or recycling power to the device. Select enable or disable.

Note

The condition that caused the valve to drift toward the trip end must be corrected before the manual reset is done. For example, if supply pressure droop caused the drift, the supply pressure must be restored before the manual reset is performed.

d Position Trip Point is defined as a % of travel from the trip end.

D Change Reset Mode defines the latching behavior of the DVC6200 SIS after a trip has occurred. There are three

choices available.

d Auto Reset— The valve will follow the loop signal from the logic solver and will not latch in the tripped position.

d Manual Reset— The valve will latch in the tripped position until the loop signal from the logic solver is at the

normal state and

the DVC6200 SIS is reset. The reset signal can be initiated by a Local Control Panel, discrete

switch wired to the AUX terminals, or from a HART command through the user interface.

d Smart Auto Reset— The valve will latch in the tripped position until the originating source that tripped the valve

provides a reset signal. If the logic solver trips the valve, and the local control panel trip button is not pressed, then the logic solver can return the valve to the normal position. However, if the local control panel trip button is pressed, then the local control panel is required to reset the valve to the normal position. (Note that the local control panel can issue a “pre-approval” if the reset button is pressed while the logic solver is still tripped. When the logic solver attempts to return the valve to the normal state, the DVC6200 SIS will follow.)

D Action on Failed Test—This displays the action taken by the instrument if a communication timeout occurs. Values

are Ramp Back or Step Back.

Solenoid Valve Test

Note

Solenoid valve health monitoring is not supported by the DVC6200 SIS

High Cv.

Instruction Manual

D103557X012

Configuration

June 2022

The DVC6200 SIS can be used to test and evaluate the operation of an external solenoid valve (SOV). This is accomplished by briefly removing power to the solenoid valve and examining the resulting pressure drop across the solenoid valve.

If the solenoid valve is connected directly to a logic solver, then the DVC6200 SIS can be used to monitor the pressures while the logic solver momentarily trips the solenoid valve. ValveLink Software can gather the data and provide a graphical representation of the actuator pressure and valve travel. Refer to the Monitoring Health of External Solenoid Valve (SOV) with FIELDVUE DVC6200 SIS Digital Valve Controllers Instruction Manual Supplement (D104028X012

) for

further details.

If the solenoid valve is wired in series with the DVC6200 SIS and logic solver, then the DVC6200 SIS can be used to initiate the momentary trip. For instructions on the physical pneumatic and electrical connections refer to the Quick Start Guide (D103556X012

Instrument Configuration to Support SOV Testing

D Relay Type— Select the appropriate relay (B or C) with the “special app” designation. Special app refers to the

additional tubing (monitoring line) that is installed between the unused output port of the DVC6200 SIS and a connection downstream of the solenoid valve, close to the actuator.

D Output Terminal Function— Since the solenoid valve is wired through the output terminals of the DVC6200 SIS, the

terminals must be enabled and configured as “SOV Test”. Note that the Transmitter/Switch selection on the printed wiring board (PWB) must also be set to “Switch”.

SOV Test Parameters (see figure 3‐6)

D Pulse Duration is the length of time of the momentary power disruption to the solenoid valve. It should be long

enough to detect a Trip Pressure Differential, but short enough to not cause the SIS valve to move. This is automatically determined during the SOV Test Calibration routine.

D Monitoring Time is the length of time from the start of the test (pulse initiation), to the end of the data gathering. It

should be long enough to allow the Reset Pressure Differential to stabilize.

D Trip Pressure Differential— During the momentary solenoid valve trip, the pressure drop across the solenoid valve is

measured. This value is the maximum pressure drop recorded during the SOV test. It is determined automatically during the SOV Test Calibration routine.

D Reset Pressure Differential— After the solenoid valve is momentarily tripped, the pressure differential across the

solenoid valve should reduce back to zero. However, depending on the Monitoring Time, the downstream pressure may not fully recover at the end of the test. This value is automatically determined during the SOV Test Calibration routine.

D SOV Test before PST configures the device to always run a SOV test prior to a PST test any time a PST is initiated.

D On Abnormal SOV Test — If SOV Test before PST is configured, this determines the behavior if the SOV test result is

abnormal. The configuration choices are to continue on to the PST, or cancel the PST.

D Independent SOV Test configures the device to allow a SOV Test to be run independent of a PST test.

Output Terminal Configuration

D Output Terminal Enable—If using the output terminal for a Position Transmitter or Switch Output, or for Solenoid

Valve Testing, this must be Enabled.

D Function—The output terminals can be configured as one of the following:

Transmitter - 420 mA output that represents 0100% of the calibrated valve travel. Limit Switch - Discrete switch (1A max) that trips at a configurable point within 0100% of calibrated valve travel. Alert Switch - Discrete switch (1A max) that trips based on a configurable device alert. SOV Test – Normally closed discrete switch that momentarily opens during a solenoid valve test.

D Fail Signal—Should the output circuit fail to operate properly the output will attempt to drive to a known state.

Depending on the nature of the failure, the circuit may or may not be able to achieve this fail state. When configured as a position transmitter, the output can be configured to fail low (< 3.6 mA). The output can be configured to fail high (> 22.5 mA) when the digital valve controller is powered. When configured as a switch, the output can be configured to drive Closed or Open.

Note

On loss of digital valve controller power, the switch circuit will always go to the open state.

Notes

Access to information in the instrument is normally obtained through the poll/response of HART communication. The Device Communicator or the control system may request any of the information that is normally available, even while the instrument is in burst mode. Between each burst mode transmission sent by the instrument, a short pause allows the Device Communicator or control system to initiate a request. The instrument receives the request, processes the response message, and then continues “bursting” the burst mode data.

Burst mode will be automatically disabled during diagnostics tests such as Valve Signature.

HART 7 allows three burst commands to be reported. When using a Tri-Loop, do not enable the 2nd or 3rd burst commands. These additional commands will result in missed messages, thus taking the Tri-Loop's output to the fault state.

D103557X012

Alert Setup

Device Communicator Configure > Alert Setup (2‐3)

An alert is a notification that the instrument has detected a problem. Alerts that are enabled and active will be recorded in the instrument memory within the Alert Record (see Section 5). Some alerts are also defined in the HART Command 48 response structure which is can be read by any HART communicating host system (refer to the DVC6200 SIS HART Field Device Specification, D103638X012

Certain critical alerts can be configured to shut down the device when active (i.e. latch in the Zero Power Condition). This can be enabled or disabled for each applicable alert. The default shutdown setting is disabled. To clear the shutdown, correct the problem and then cycle power to the instrument (or disable the alert).

Alerts may be enabled or disabled with the instrument In Service, Out of Service, Protection On, or Protection Off. However, shutdown alerts can only be enabled or disabled while Protection is off.

For a detailed explanation of the alerts and the recommended actions, refer to Section 5.

Change to HART 5 / Change to HART 7

Device Communicator Service Tool > Maintenance > Change to HART 5 / Change to HART 7 (3-5-3)

This procedure changes the instrument from HART Universal Revision 5 to HART Universal Revision 7 (or vice versa). Before proceeding, verify that your systems are prepared to support HART Universal Revision 7 devices. Follow the prompts on the Device Communicator display.

Note

This procedure must never be done while the valve is in service and controlling the process. Depending on the control system or asset management system attached, complete system reset may be required to reestablish HART communication. Consult the system documentation for further information.

Section 4 Calibration 44

Note

Fast-key sequences are only applicable to the 475 Field Communicator. They do not apply to the Trex Device Communicator.

Fast-key sequences are not applicable to the DVC6200 SIS High Cv. ValveLink software 13.6 or higher is required to calibrate a DVC6200 SIS High Cv.

Calibration Overview

When a DVC6200 SIS digital valve controller is ordered as part of a control valve assembly, the factory mounts the digital valve controller on the actuator and connects the necessary tubing, then sets up and calibrates the controller.

For digital valve controllers that are ordered separately, recalibration of the analog input or pressure sensors generally is unnecessary. However, after mounting on an actuator, perform the initial setup then calibrate travel by selecting Configure > Calibration > Travel Calibration > Auto Calibration. For more detailed calibration information, refer to the following calibration procedures.

Device Communicator Configure > Calibration (2-4)

Auto Travel Calibration - see page 40

Manual Travel Calibration - see page 41

Pushbutton Calibration - see page 42

Pressure Sensor Calibration - see page 43

Analog Input Calibration - see page 44

Relay Adjustment - see page 45

PST Calibration - see page 47

SOV Test Calibration - see page 47

Note

The Instrument Mode must be Out Of Service and the Protection set to None before the instrument can be calibrated.

If you are operating in burst mode, we recommend that you disable burst before continuing with calibration. Once calibration is complete, burst mode may then be turned back on.

WARNING

During calibration the valve will move full stroke. To avoid personal injury and property damage caused by the release of pressure or process fluid, isolate the valve from the process and equalize pressure on both sides of the valve or bleed off the process fluid.

Travel Calibration

If a double‐acting relay is used, you will be prompted to run the relay adjustment when auto or manual calibration is selected. Select Yes to adjust the relay, select No to proceed with calibration. For additional information, refer to Relay Adjustment on page 45.

Note

Relay adjustment is not applicable to DVC6200 SIS High Cv digital valve controllers.

Auto Calibration

1. The auto calibration procedure is automatic. It is completed when the Calibration menu appears.

During calibration, the instrument seeks the high and low end points and the minor loop feedback (MLFB) and output bias. By searching for the end points, the instrument establishes the limits of physical travel, i.e. the actual travel 0 and 100% positions. This also determines how far the relay beam swings to calibrate the sensitivity of the MLFB sensor.

Note

Minor loop feedback is not relevant for DVC6200 SIS High Cv digital valve controllers.

2. Place the instrument In Service and verify that the travel properly tracks the current source.

If the unit does not calibrate, refer to table 4‐1 for error messages and possible remedies.

Table 4‐1. Auto Calibrate Travel Error Messages

Error Message Possible Problem and Remedy

Power failure occurred during Auto Calib

Auto Calib did not complete within the time limit.

Insufficient travel

Drive signal exceed low limit; check supply pressure

Drive signal exceed high limit; check supply pressure

The analog input signal to the instrument must be greater than 3.8 mA. Adjust the current output from the control system or the current source to provide at least 4.0 mA.

The problem may be one or the other of the following:

1. The tuning set selected is too low and the valve does not reach an end point in the allotted time. Select Manual Setup > Tuning > Travel Tuning > Stabilize/Optimize then Increase Response (selects next higher tuning set).

2. The tuning set selected is too high, valve operation is unstable and does not stay at an end point for the allotted time. Select Manual Setup > Tuning > Travel Tuning > Stabilize/Optimize then Decrease Response (selects next lower tuning set).

Prior to receiving this message, did the instrument output go from zero to full supply? If not, verify instrument supply pressure by referring to the specifications in the appropriate actuator instruction manual. If supply pressure is correct, check instrument pneumatic components (I/P converter and relay).

If the instrument output did go from zero to full supply prior to receiving this message, then verify proper mounting by referring to the appropriate mounting procedure in the Installation section and checking the magnet array for proper alignment.

1. Check supply pressure (reverse‐acting relay)

2. Friction is too high.

1. Check supply pressure (direct‐acting relay)

2. Friction is too high

Manual Calibration

Two procedures are available to manually calibrate travel:

D Analog Adjust— This procedure is used when you can manually change the 4-20 mA current source to move the

valve.

D Digital Adjust— This procedure is used when the 4-20 mA current source cannot be manually changed.

Analog Calibration Adjust

Connect a variable current source to the instrument LOOP + and LOOP - terminals. The current source should be capable of generating 4 to 20 mA.

Follow the prompts on the Device Communicator display to calibrate the instrument's travel in percent.

Note

0% Travel = Valve Closed 100% Travel = Valve Open

1. Adjust the input current until the valve is near mid‐travel. Press OK.

Note

In steps 2 through 7 the accuracy of the current source adjustment affects the position accuracy.

2. Adjust the current source until the valve is at 0% travel, then press OK.

3. Adjust the current source until the valve is at 100% travel, then press OK.

4. Adjust the current source until the valve is at 0% travel, then press OK.

5. Adjust the current source until the valve is at 100% travel, then press OK.

6. Adjust the current source until the valve is at 5% travel, then press OK.

7. Adjust the current source until the valve is at 95% travel, then press OK.

8. Place the instrument In Service and verify that the travel properly tracks the current source.

Digital Calibration Adjust

Connect a variable current source to the instrument LOOP + and LOOP - terminals. The current source should be set between 4 and 20 mA.

Follow the prompts on the Device Communicator display to calibrate the instrument's travel in percent.

1. Adjust the input current until the valve is near mid‐travel. Press OK.

If another adjustment is required, repeat step 7. Otherwise, select Done and go to step 8.

8. Place the instrument In Service and verify that the travel properly tracks the current source.

Pushbutton Calibration

A pushbutton near the wiring terminals in the terminal box provides a quick means to autocalibrate the instrument. The button must be pressed for 3 to 10 seconds. Autocalibration will move the valve through the full range of travel whether the Instrument Mode is In Service or Out of Service. However, if the Write Protection is Protected, this button will not be active. To abort, press the button again for 1 second. The calibration button is disabled by default. To enable it, go to Manual Setup > Instrument > Calibration Button.

Note

The autocal pushbutton will not be active if the instrument is Locked in Safety.

This calibration procedure is recommended whenever the I/P converter or pneumatic relay/spool valve is replaced. Do not use the pushbutton calibration for initial calibration when mounting the instrument on an actuator, or if the printed wiring board assembly was replaced.

If you suspect calibration has changed due to drift, first perform a Valve Signature diagnostic test using ValveLink software to capture the asfound data for future root cause analysis.

Relay Adjustment

Before beginning travel calibration, check the relay adjustment. Replace the digital valve controller cover when finished.

Note

Relay B and C are not user‐adjustable.

Relay adjustment is not applicable for DVC6200 SIS High Cv digital valve controllers.

Double‐Acting Relay

The double‐acting relay is designated by “Relay A” on a label affixed to the relay itself. For double‐acting actuators, the valve must be near mid‐travel to properly adjust the relay. The Device Communicator will automatically position the valve when Relay Adjust is selected.

Rotate the adjustment disc, shown in figure 4‐1, until the output pressure displayed on the Device Communicator is between 50 and 70% of supply pressure. This adjustment is very sensitive. Be sure to allow the pressure reading to stabilize before making another adjustment (stabilization may take up to 30 seconds or more for large actuators).

Low bleed relay stabilization may take approximately two minutes longer than the standard relay.

PST Calibration

This procedure permits you to run the Partial Stroke Calibration, which enables the Partial Stroke Test. It establishes values for Partial Stroke Pressure Limit, Pressure Set Point and Pressure Saturation Time for End Point Pressure Control, Travel Deviation Alert Point and Travel Deviation Time. The Partial Stroke Calibration also sets default values for max travel movement, test speed, and test pause time.

Note

You must take the instrument out of service before running Partial Stroke Calibration.

Ensure that the instrument is put back in service after the completing the calibration procedure.

SOV Test Calibration

Note

SOV Test Calibration is not applicable to DVC6200 SIS High Cv digital valve controllers.

This procedure is used when a solenoid valve is wired to the Output terminals. During this routine, the output terminal circuit is interrupted momentarily to trip the solenoid. During the test, the Trip Pressure Differential, Recovery Pressure Differential, and Valve Travel are monitored. The test attempts to find the optimal trip duration which results in a measurable pressure drop across the solenoid, but no valve travel movement. If the proper duration cannot be established within 10 tries, the test will stop.

Port A Overpressurized requires that both the Port A Overpressurized Alert and the Port A Output Pressure Limit are enabled and applies to single acting direct applications only. The alert is active if the output pressure from Port A of the DVC6200 SIS exceeds the configured pressure limit setting. Check the supply pressure regulator for damage and verify its pressure set point.

Pressure Fallback Active is active when the instrument has detected a problem with the travel feedback and is now controlling the output like an I/P transducer.

Pressure Sensor Failure is active if any of the 3 pressure sensor readings (output A, output B, supply) are outside the range of 24.0 to 125.0% of the calibrated pressure for more than 60 seconds. If this alert is active, check the instrument supply pressure, ensure the printed wiring board assembly is properly mounted onto the module base assembly, and ensure the pressure sensor o-rings are properly installed. If the alert persists after restarting the instrument, replace the printed wiring board assembly.

PST Abnormal indicates that a partial stroke test has failed. The criteria for determining an abnormal partial stroke test is user configurable. See page 32 for PST Abnormal Criteria.

NOTICE

If a PST Abnormal alert is active, there may be potential energy stored in the valve and actuator assembly. Sudden release of this energy may cause the valve to suddenly open or close, resulting in equipment damage.

PST Prohibited indicates that a partial stroke test was initiated, but then aborted due to abnormal conditions. The criteria for prohibiting a partial stroke test is user configurable. See page 33 for PST Prohibited critera.

PST Pass indicates that a partial stroke test has completed normally. This alert will automatically clear. The timeout setting for the alert shares the same configuration setting as the Tripped by LCP Alert Latch.

Reference Voltage Failure is active if there is a failure associated with the internal voltage reference. If this alert is active, replace the printed wiring board assembly.

SIS Hardware Failure is active if a demand has occurred, but the electronics hardware failed to take control of the I/P drive.

Manual Reset Required indicates that the DVC6200 SIS is in the tripped position. In order for the instrument to follow the loop signal, it must be reset by pressing the Green button on the LCP, or perform a Reset Latch with the host.

SIS Program Flow Failure is active if the firmware is not performing the expected series of calculations.

SIS Stroke Performance— If the DVC6200 SIS is tripped to the safety position and/or returns to the normal position, the

instrument will record the demand and/or return stroke time, demand break out time, and the calendar time that these events happened. This alert is active if any of the configured thresholds are exceeded.

Supply Pressure High is active if the supply pressure falls above the supply pressure high alert point.

Supply Pressure Low is active if the supply pressure falls below the supply pressure low alert point.

Temperature Sensor Failure is active when the instrument temperature sensor fails, or the sensor reading is outside of

the range of -60 to 100°C (-76 to 212°F). The temperature reading is used internally for temperature compensation of inputs. If this alert is active, restart the instrument. If the alert persists, replace the printed wiring board assembly.

Travel Accumulator High is active if the Travel Accumulator exceeds the Travel Accumulator Alert Point. The Travel Accumulator totalizes the travel of the valve when the deadband is exceeded. To clear the alert, set the Travel Accumulator to a value less than the alert point. See figure 5‐2.

Travel Alert Hi is active when the Travel exceeds the Travel Alert Hi Point. Once the alert is active, the alert will clear when the Travel falls below the Travel Alert Hi Point minus the Travel Alert Deadband. See figure 5‐1.

Note

The Travel Alert Hi Hi and Travel Alert Lo Lo points are used to calculate the stroke time in the event of a demand. The values are typically set to 99% and 1% respectively, however it is not necessary to enable the alert. Stroke time can be read from the device with ValveLink software.

Travel Alert Hi-Hi is active when the Travel exceeds the Travel Alert Hi Hi Point. Once the alert is active, the alert will clear when the Travel falls below the Travel Alert Hi Hi Point minus the Travel Alert Deadband. See figure 5‐1.

Travel Alert Lo is active when the Travel is below the Travel Alert Lo Point. Once the alert is active, the alert will clear when the Travel exceeds the Travel Alert Lo Point plus the Travel Alert Deadband. See figure 5‐1.

Travel Alert Lo-Lo is active when the Travel is below the Travel Alert Lo Point. Once the alert is active, the alert will clear when the Travel exceeds the Travel Alert Lo Point plus the Travel Alert Deadband. See figure 5‐1.

Travel Cutoff Hi is active when the Travel exceeds the Hi Cutoff Point.

Travel Cutoff Lo is active when the Travel falls below the Lo Cutoff Point.

Travel Deviation— If the difference between the Travel Target and the Travel exceeds the Travel Deviation Alert Point

for more than the Travel Deviation Time, the Travel Deviation Alert is active. It remains active until the difference between the travel target and the Travel is less than the Travel Deviation Alert Point minus the Travel Alert Deadband. See figure 5‐1.

Travel Sensor Failure is active if the sensed travel is outside the range of 25.0 to 125.0% of calibrated travel. If this alert is active, check the instrument mounting. Also, check that the electrical connection from the travel sensor is properly plugged into the printed wiring board assembly. After restarting the instrument, if the alert persists, troubleshoot the printed wiring board assembly or travel sensor.

Tripped by the LCP indicates that the DVC6200 SIS is in the tripped position as a result of someone pressing the trip button on the local control panel. This alert will automatically clear only after the valve returns to the normal state and the Tripped by LCP Alert Latch timeout has expired.

Variable out of Range is active if one or more of the measured analog sensor readings (loop current, pressure, temperature, or travel) is saturated or reading out of its configured range. The condition may be due to improper configuration or physical setup and not be due to a sensor malfunction.

Deadband Principle of Operation

The deadband is the percent (%) of ranged travel around a travel reference point where no change in alert status will occur. This prevents the alert from toggling on and off when operating near the alert point.

The Travel Alert Deadband applies to the Travel Deviation Alert as well as the Travel Alert Hi, Lo, Hi Hi, and Lo Lo. Figure 5‐1 illustrates the principle behind setting and clearing a Travel Alert Hi. The alert is set when the travel exceeds the alert point, and is cleared when it falls below the deadband.

The Cycle Counter and Travel Accumulator Deadband applies to both the Cycle Count High Alert and the Travel Accumulator High Alert. The deadband establishes a zone around a travel reference point. The travel reference point gets reestablished to the point of travel reversal that occurs outside of the deadband. The deadband must be exceeded before a change in travel direction will be counted as a cycle and the accumulated travel (up to the point of travel reversal) is added to the total accumulation. See figure 5‐2.

Note

DVC6200 SIS High Cv requires ValveLink software 13.6 or higher to perform the Diagnostic procedures.

WARNING

During stroke valve, partial stroke, and demand mode tests the valve will move. To avoid personal injury and property damage caused by the release of pressure or process fluid, when used in an application where the valve is normally closed, provide some temporary means of control for the process.

Stroke Valve

Follow the prompts on the Device Communicator display to select from the following:

D Done—Select this if you are done. All ramping is stopped when DONE is selected.

D Ramp Open—ramps the travel toward open at the rate of 1.0% per second of the ranged travel.

D Ramp Closed—ramps the travel toward closed at the rate of 1.0% per second of the ranged travel.

D Ramp to Target—ramps the travel to the specified target at the rate of 1.0% per second of the ranged travel.

D Step to Target—steps the travel to the specified target.

Partial Stroke Test

There are multiple ways that a partial stroke test can be initiated with the DVC6200 SIS.

D Automatic (Scheduled)

The Auto Partial Stroke Test allows the partial stroke test to be scheduled by the DVC6200 SIS. The test is scheduled in number of hours between tests. Any power cycle will reset the test clock timer.

D Local Pushbutton

A partial stroke test command may be sent to the digital valve controller using a set of contacts wired to the auxiliary +/- terminals. To perform a test, the contacts must be closed for 3 to 10 seconds and then opened. To abort the test, close the contacts for 1 second. The last set of diagnostic data is stored in the instrument memory for later retrieval via ValveLink software.

D Local Control Panel

The LCP100 or LPC200 local control panel is wired directly to the DVC6200 SIS digital valve controller.

The “Valve Test” push button (see figure 5‐3) allows the valve to perform the configured partial stroke test.

- Press and hold for 3 to 10 seconds

The test can be overridden by the “Valve Close” button, “Valve Open” button, or if an emergency demand occurs.

1. Disconnect the power from the solenoid valve, but maintain the 20 mA current to the digital valve controller. The valve should move to its “fail safe” position.

2. Maintain power to the solenoid valve and adjust the current to the digital valve controller from 20 mA to 4 mA. The valve should move to its “fail safe” position.

3. Remove power from the solenoid valve and adjust the current to the digital valve controller from 20 mA to 4 mA. The valve should go to its “fail safe” position.

If a solenoid is not used with a DVC6200 SIS,

1. Adjust the current to the digital valve controller from 20 mA to 4 mA. The valve should move to its “fail safe” position.

Note

The above tests are applicable for single‐acting direct relay A or C or direct-acting HCV1, HCV2, or HCV3. If single‐acting reverse relay B or reverse-acting HCV1 or HCV2 are used adjust the current from 4 mA (normal state) to 20 mA (trip state).

D Multi‐drop Mode (DVC6200 SIS is powered by a 24 VDC power source)

If the DVC6200 SIS is pneumatically in series with a solenoid valve, and shares a single power source,

1. Disconnect power to both devices. The valve should go to its “fail safe” position.

If the DVC6200 SIS is pneumatically in series with a solenoid valve, with independent power sources,

1. Connect a 24 VDC power supply to the solenoid valve and a second 24 VDC power supply to the DVC6200 SIS.

2. Disconnect the solenoid valve power supply, but maintain the power supply to the DVC6200 SIS. The valve should go to its “fail safe” position quickly.

3. Maintain the power supply to the solenoid valve and disconnect the DVC6200 SIS power supply. The valve should go to its “fail safe” position, although not as quickly as it does in the previous scenario.

If DVC6200 SIS is alone, without a solenoid valve,

1. Disconnect power to the digital valve controller. The valve should go to its “fail safe” position.

Solenoid Valve Health Monitoring

Note

Solenoid valve health monitoring is not supported by the DVC6200 SIS

Solenoid valve health monitoring requires the following setup:

D Single-acting actuator

D Solenoid valve installed between the DVC6200 SIS pressure output and the actuator

D Unused output pressure port of the DVC6200 SIS connected between the solenoid and the actuator, close to the

actuator

D Relay configured as “special application”

D Output terminal configured as “Limit Switch” (only required when the solenoid valve is wired in series with the

DVC6200 SIS)

High Cv.

If the solenoid valve is wired directly to the logic solver, the following steps can be used to test the solenoid valve.

1. Momentarily interrupt the power to the solenoid valve through the Logic Solver (typically 100 to 200 milliseconds). The duration of the interruption should be short enough so that the safety valve travel does not move, but long enough to so that a pressure drop across the solenoid valve is detected.

2. Properly configured, data collection will occur automatically and will be stored onboard the DVC6200 SIS.

3. With ValveLink software, upload the diagnostic data from the triggered profile menu.

4. Examine the graph and observe that there was a change in the pressure reading downstream of the solenoid.

If the solenoid valve is wired in series with the DVC6200 SIS and logic solver, the following steps can be used to test the solenoid valve.

1. With ValveLink software, run the Solenoid Valve Test diagnostic. When configured correctly, the DVC6200 SIS will conduct the power interruption and collect the data.

2. Examine the graph and observe that there was a change in the pressure reading downstream of the solenoid.

Section 6 Maintenance and Troubleshooting66

The DVC6200 SIS digital valve controller enclosure is rated Type 4X and IP66, therefore periodic cleaning of internal components is not required. If the DVC6200 SIS coated or layered with industrial or atmospheric contaminants, it is recommended that the vent (key 52) be periodically removed and inspected to ensure there is no partial or full obstruction. If the vent appears to be partially or fully obstructed, it must be cleaned or replaced. Lightly brush the exterior of the vent to remove contaminants and run a mild water/detergent solution through the vent to ensure it is free of any obstruction. Allow the vent to dry before reinstalling.

WARNING

Personal injury or property damage can occur from cover failure due to overpressure. Ensure that the housing vent opening is open and free of debris to prevent pressure buildup under the cover.

WARNING

is installed in an area where the exterior surfaces tend to get heavily

To avoid static discharge from the plastic cover when flammable gases or dust are present, do not rub or clean the cover with solvents. To do so could result in a spark that may cause the flammable gases or dust to explode, resulting in personal injury or property damage. Clean with a mild detergent and water only.

WARNING

Avoid personal injury or property damage from sudden release of process pressure or bursting of parts. Before performing any maintenance procedures on the DVC6200 SIS digital valve controller:

D Always wear protective clothing, gloves, and eyewear.

D Do not remove the actuator from the valve while the valve is still pressurized.

D Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the

actuator cannot suddenly open or close the valve.

D Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure

from both sides of the valve.

D Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.

D Check with your process or safety engineer for any additional measures that must be taken to protect against process

media.

D Vent the pneumatic actuator loading pressure and relieve any actuator spring precompression so the actuator is not

applying force to the valve stem; this will allow for the safe removal of the stem connector.

WARNING

When using natural gas as the supply medium, or for explosion proof applications, the following warnings also apply:

D Remove electrical power before removing the housing cap. Personal injury or property damage from fire or explosion

may result if power is not disconnected before removing the cap.

D Remove electrical power before disconnecting any of the pneumatic connections.

Instruction Manual

D103557X012

D When disconnecting any of the pneumatic connections or any pressure retaining part, natural gas will seep from the

unit and any connected equipment into the surrounding atmosphere. Personal injury or property damage may result from fire or explosion if natural gas is used as the supply medium and appropriate preventive measures are not taken. Preventive measures may include, but are not limited to, one or more of the following: ensuring adequate ventilation and the removal of any ignition sources.

D Ensure that the cover is correctly installed before putting this unit back into service. Failure to do so could result in

personal injury or property damage from fire or explosion.

Instruction Manual

Appendix A Principle of OperationAA−A

HART Communication

The HART (Highway Addressable Remote Transducer) protocol gives field devices the capability of communicating instrument and process data digitally. This digital communication occurs over the same two‐wire loop that provides the 4‐20 mA process control signal, without disrupting the process signal. In this way, the analog process signal, with its faster update rate, can be used for control. At the same time, the HART protocol allows access to digital diagnostic, maintenance, and additional process data. The protocol provides total system integration via a host device.

The HART protocol uses frequency shift keying (FSK). Two individual frequencies of 1200 and 2200 Hz are superimposed over the 4‐20 mA current signal. These frequencies represent the digits 1 and 0 (see figure A‐1). By superimposing a frequency signal over the 4-20 mA current, digital communication is attained. The average value of the HART signal is zero, therefore no DC value is added to the 4‐20 mA signal. Thus, true simultaneous communication is achieved without interrupting the process signal.

A6174

-0.5V

1200 Hz “1”

AVERAGE CURRENT CHANGE DURING COMMUNICATION = 0

2200 Hz “0”

ANALOG SIGNAL

The HART protocol allows the capability of multidropping, i.e., networking several devices to a single communications line. This process is well suited for monitoring remote applications such as pipelines, custody transfer sites, and tank farms. See table 6‐2 for instructions on changing the printed wiring board DIP switch configuration to multidrop.

DVC6200 SIS Digital Valve Controller

The DVC6200 SIS digital valve controller housing contains the travel sensor, terminal box, pneumatic input and output connections and a module base that may be easily replaced in the field without disconnecting field wiring or tubing. The module base contains the following submodules: I/P converter, printed wiring board (pwb) assembly, and pneumatic relay. The relay position is detected by sensing the magnet on the relay beam via a detector on the printed wiring board. This sensor is used for the minor loop feedback (MLFB) reading. The module base can be rebuilt by replacing the submodules. See figures A‐3, A‐4, A‐5, and A‐6. Refer to figure A‐7 and A‐8 for DVC6200 SIS High Cv.

June 2022

E1362

DVC6200 SIS digital valve controllers are loop‐powered instruments that provide a control valve position proportional to an input signal from the control room. The following describes a double‐acting digital valve controller mounted on a piston actuator.

The input signal is routed into the terminal box through a single twisted pair of wires and then to the printed wiring board assembly submodule where it is read by the microprocessor, processed by a digital algorithm, and converted into an analog I/P drive signal.

As the input signal increases, the drive signal to the I/P converter increases, increasing the I/P output pressure. The I/P output pressure is routed to the pneumatic relay submodule. The relay is also connected to supply pressure and amplifies the small pneumatic signal from the I/P converter. The relay accepts the amplified pneumatic signal and provides two output pressures. With increasing input (4 to 20 mA signal), the output A pressure always increases and the output B pressure decreases. The output A pressure is used for double‐acting and single‐acting direct applications. The output B pressure is used for double‐acting and single‐acting reverse applications. As shown in figure A‐3, A‐4, A‐5, and A‐7 the increased output A pressure causes the actuator stem to move downward. Stem position is sensed by the non‐contact travel feedback sensor. The stem continues to move downward until the correct stem position is attained. At this point the printed wiring board assembly stabilizes the I/P drive signal. This positions the flapper to prevent any further increase in nozzle pressure.

As the input signal decreases, the drive signal to the I/P converter submodule decreases, decreasing the I/P output pressure. The pneumatic relay decreases the output A pressure and increases the output B pressure. The stem moves upward until the correct position is attained. At this point the printed wiring board assembly stabilizes the I/P drive signal. This positions the flapper to prevent any further decrease in nozzle pressure.
