Feedback

In a control process the control valve has to adjust the liquid fuel flow rate (often corresponding to the thermal energy of the process) depending on the signal coming from the controller. To this purpose , the valve is equipped with an actuator capable to modify its opening value, forcing the resistance produced by the fluid flowing inside it. Control valves change flow rate according to a modulated mode, producing finite variations of the inside flowing path of the fluid, corresponding with finite variations of the actuator input signal, coming from the controller. The servomechanism is made up, for example, by an electic motor, by a reducer unit and of a transmission mechanical system that operates the valve. Various auxiliary components could be present such as electrical and mechanical limit switches for safety, manual override devices, position detectors and indicators. The controller determines the drive output for the valve from the dynamic behaviour of the process in order that the required value of the process variable can be maintained. When position feedback is required, it is usually supplied by a potentiometer fitted to the actuator.

Valve control parameters

- Actuator time (_At_): time required by the valve to move from completely open to completely closed (and viceversa), selectable in seconds; it is a mechanical characteristics of the valve + actuator assembly. NOTE: if the actuator run is mechanically reduced it is necessary to reduce the _At_ parameter value accordingly.

- Minimum pulse time (t_Lo): selectable in % of the actuator time (resolution 0.1%). This parameter sets the minimum value of command below which the actuator does not move; by increasing t_Lo it is possible to lower the mechanical stress on the valve, allowing a higher accuracy in positioning.

- Pulsating command band (t_Hi): selectable in % of the actuator time (resolution 0.1%). Whenever the valve has to move to another position, this parameter defines a band inside which the valve positioning command is pulsating instead of continuos; the length of each pulse is proportional to the deviation and higher or equal to t_Lo. This type of pulsating command allows a very accurate positioning of the valve, with or without feedback, expecially in case of high mechanical inertia. The pulsating command positioning is disabled by setting t_Hi = 0.

- Dead Band (_db_): selectable in display units, defines a band around the Setpoint inside which the controller gives no command to the valve (Open = OFF; Close = OFF). This parameter is useful to save the actuator from mechanical stress when the process has already settled; the dead band function is disabled by setting _db_ = 0.

PULSATING COMMAND VALVE POSITIONING, AVAILABLE ONLY ON V0, V1 AND V2 CONTROL TYPES

V0 - for floating valves without feedback potentiometer; V1 - for floating valves with potentiometer and position indication; V2 - for valves with position feedback potentiometer and position indication.

Models V0 and V1 have a similar behaviour. Every request for change that is greater than the minimum pulse is sent to the actuator via an OPEN/CLOSE relay.

8 • TIMER, TIMER + 2 SETPOINTS FUNCTIONS

The timer function can be enabled in Hrd configuration by setting parameter hrd.1 = +16 (+48 to enable the 2 setpoints selection). The timer operating mode can be defined through parameters _S.S.t. (timer start/stop) and _ _r.t (timer reset). The timer setpoint can be programmed in level 1 configuration (full scale 9999 sec.). The Start/Stop and Reset of the timer can be executed through a digital input or the tripping of an alarm (AL1, AL2, AL3, ALHb). The Reset command (active on state) reset the timer and keeps it zeroed even if the Start Command is active. It is possible to configure the timer for Auto-Reset function (timer Reset at every Stop). It is possible (through diSP parameter) to show the timer count on display SV. When the timer Setpoint (tS) is reached, it is possible to turn ON an output or select SP2 control Setpoint.

The ramp between SP1 and SP2 is defined through GrSP parameter (setpoint gradient). GrSP = 0 means immediate change.

The multiset function can be enabled in Hrd configuration by setting parameter hrd.1 = +64. It is possible to use up to 4 local setpoints, selectable through binary combinations of digital inputs (IN1, IN2); the M/A configurable key can be used to select SP1/SP2. The faceplate LEDs can be configured to display the active SP. SETPOINT GRADIENT (parameter Gr.SP): if Gr.SP = 0 the change from one SP to another is immediate; if Gr.SP ≠ 0 the instrument goes from one the SP to another with the defined ramp. If Gr.SP ≠ 0, at power-on and on AUTO/MAN commutation the SP is assumed equal to PV and then reaches the local or remote SP with the defined ramp.

Every action updates the presumed position of a virtual potentiometer calculated on the basis of the declared actuator time. In this way, there is always a presumed position of the valve that is compared with the controller output. Once the valve reaches a fully opened or fully closed position as calculated by the virtual potentiometer, the controller will supply a series of pulses in the same direction in equal intervals of time with the length of the minimum pulse in order to ensure that the actual end stop is reached. The actuators are usually protected against an OPEN command when in the fully open position and a CLOSE command in the fully closed position. The V2 model reads the position of the valve through an auxiliary analogue input, conditioned to give a percentage (0.0 - 100.0%), it compares it with the controller output, and sends the appropriate command to the valve. The auxiliary input of the controller is used to acquire the valve position. Calibration is required to detect the potentiometer readings that correspond to the maximum and minimum valve positions. The potentiometer is normally powered by the same controller.

V3 - for floating valves without position indication, PI control V4 - for floating valves with valve position potentiometer indication, PI control; when the difference between the requested position from the controller and the proportional component is greater than the value that corresponds to the minimum pulse, the controller supplies an OPEN or CLOSE command equal to the minimum pulse. The integral component of the controller is reset to zero, each time the controller change the valve position (integral desaturation). The frequency and the width of the pulses is related to the integral time that has been set. (_ti_).

This alarm detects (when current should be flowing) an interruption in the control loop caused by a possible shortcircuit probe, an inverted probe connections or broken heater circuit. If enabled (AL.nr) the alarm is activated if the variable does not increase when the controller should be heating (reduce when cooling) at maximum power within a set time (LbA.t). The value of the variable is enabled only outside the proportional band, when alarm is ON the power is limited at a set value (LbA.P). The alarm condition resets as soon as an increase in temperature is detected (or reduction if on the cooling channel) or by pressing the “ ∇ ” and “Raise” keys simultaneously in the Out.P position of level 1 menu. If LbA.t = 0 the LBA function is disabled.

LBA ALARM FUNCTION

The type of alarm requires the current transformer input (CT). It can indicate the variations of load current measured through HB input, in the range (Lo.S2 ... HI.S2). It is enabled by a configuration code (Hrd, AL.nr); in this case the alarm set-point is expressed as HB scale digits. The alarm function and the associated control output are selected through parameter Hb_F (“Out” menu). The setpoints for alarm is AL.Hb. The direct HB alarm intervenes if the current transformer input falls below the entered setpoint for a time set in Hb_t during periods in which the main output is ON. The HB alarm can be activated only if the ON times are greater than 0,4 seconds. The HB alarm provides monitoring of the load current even during the OFF period of the cycle time of the MAIN output: If the measured current exceeds 12% of the CT input scale for a time set in Hb_t during periods in which the main control relay is in the OFF state, the alarm intervenes. The alarm is reset automatically when the alarm conditions have been cleared. If the alarm AL.Hb is entered as = 0, both types of HB alarm are disabled and the associated relay is disenergised. The load current reading is displayed as InP.2 in level 1 menu. NOTE: the ON/OFF times refer to the entered cycle time. The alarm Hb_F = 3 (7), for analog output is ON when the load current is lower than the alarm setpoint; the alarm is disabled if the control output is lower than 2%.

This function, if enabled, partializes the output power and increases it proportionally to the time elapsed since the power-up of the instrument with respect to the preset time 0.0 ... 500.0 min (“ SoFt ” parameter, CFG). The soft-start is mutually exclusive with self-tuning and it is activated each time the instrument is powered up. The soft-start function is reset by switching the unit to Manual control.

11 • SOFT-START

Proportional Action:

the term whose contribution to the output is proportional to the deviation of the input (the deviation is the difference between the measured variable and the set-point).

Derivative Action:

the term whose contribution to the output is proportional to the rate of variation of the input signal deviation.

Integral Action:

the term whose contribution to the output is proportional to the integral with time of the input signal deviation.

The influence that the Proportional, Derivative and Integral terms have on the process under control

* An increase in the P.B. reduces the oscillations but increases the deviation. * A reduction of the P.B. reduces the deviation but provokes oscillation of the controlled variable (if the value of the P.B. is too low, the system will tend to be unstable). * An increase in the Derivative Action, which corresponds to an increase of the Derivative Time, reduces the deviation and also prevents oscillation up to a critical value of the Derivative Time, above which the deviation increases and prolonged oscillations will occur. * An increase of the Integral Action, which corresponds to a reduction of the Integral Time, helps to remove the deviation between the controlled variable and the set-point when the system has settled down. If the value of the Integral Time is too long (Weak integral action) it is possible that there will be a persistent deviation between the input and the set-point.

14 • SOFTWARE ON / OFF SWITCHING FUNCTION

How to switch OFF: hold down the “ F ” and “Raise” keys together for 5 seconds to disactivate the instrument, which puts itself in the OFF

state while keeping the line supply connected, keeping the process value displayed, while the SV display is OFF. All the outputs (alarm as well as control) are in the OFF state (logic 0 or relay disenergised) and all the functions of the instrument are disabled except the switch-on function and the digital communication. How to switch ON: hold down the “ F ” key for 5 seconds and the instrument will pass from the OFF state to the ON state. If the power is removed during the OFF state, the next time the power is connected, the instrument will find itself in the same OFF state (the ON or OFF state is memorised). The function is normally enabled. The function can be disabled by setting the parameter Prot = Prot +16. This function can be executed through a digital input (d.i.F.1 or d.i.F.2).

The function works very well for single output systems (heating or cooling). The self-tuning action has the scope of calculating the optimum values for the control parameters during the start up of the process. The variable (for example the temperature) must be that assumed at zero power (ambient temperature). The controller supplies maximum output power until a point below the set-point is reached. It then zeros the power again. By measuring the overshoot, and the time needed to arrive at maximum, the PID parameters are calculated. Once the action has finished its calculations, it disables itself automatically and the control proceeds normally to bring the system to set-point.

How to activate selftuning:

A. Activation at turn-on

1. Adjust the setpoint at requested value

2. Enable selftuning setting Stun parameter at value (CFG menu)

3. Switch the instrument off

4. Be sure that the temperature value approximately corresponds to the ambient temperature

5. Switch the instrument on

B. Activation from keyboard

1. Be sure that the M/A key is enabled for Start/Stop selftuning function

(butt code = 4 Hrd menu)

2. Adjust the temperature value next to the ambient temperature one.

3. Set the setpoint at requested value.

4. Press M/A key to activate selftuning. (Attention: if the key is pressed twice, selftuning will be disabled)

The procedure takes place automatically until the the end. When finishing, the new PID parameters are stored: proportional band, integral and integrated times calculated for the active action (heat or cool). In case of double action (heat or cool) the parameters of the opposite action are calculated maintaining the initial ratio between the respective parameters (ex.: CPb = HPb * K; where K = CPb / HPb when starting selftuning). At the end, the Stun code is automatically cancelled.

Remarks:

• Procedure interrupts when the setpoint value is exceeded during the course. In this case the Stun code is not cancelled.

• It is suggested to enable one of the configurable leds for the selftuning status indication. If one of Led1, Led2, Led3 = 3 (or 19) parameters are

set in the Hrd menu, the corresponding led is on (or flashing), during the active selftuning phase.

16 • AUTO-TUNING

If this function is enbled, it is not possible to enter the PID parameters manually. It can be one of two types: permanent or one-shot. The first continual examines system oscillations to recalculate the optimum values to reduce these oscillations. It does not intervene if the oscillations are less than 1,0% of the proportional band. It is interrupted if the set-point is changed, and is reinserted when the set-point is stable. The calculated PID parameters are not stored. If power is removed from the instrument, the instrument reverts to the values entered before auto-tuning was enabled. One-shot auto-tuning is useful for calculating the values around set-point. It produces a variation in output of 10% of the current power and it examines the effect of the overshoot over time. The parameters are stored, and replace those perviously entered. After this disturbance, the controller returns to control at the set-point using the new parameters.

Cooling PID parameters are thus calculated starting from the heating ones according to the following ratio. (i.e.: c.MEd = 1 (oil), H_Pb = 10, H_dt = 1, H_It = 4 brings to: C_Pb = 12,5, C_dt = 1 , C_It = 4) It is suggested to select the following values when setting output cycle times: Air T Cycle Cool = 10 sec. Oil T Cycle Cool = 4 sec. Water T Cycle Cool = 2 sec. NB.: By this mode cooling parameters cannot be modified.

• CURRENT TRANSFORMER

19 • ACCESSORIES

These transformers are used for current measurements at 50 ÷ 60Hz from 25A to 600A (nominal primary current). The peculiar characteristic of these transformers is the high number of secondary turns. This means a very low secondary current directly suitable for an electronic circuit of measurement. The secondary current may be detected as a voltage on a resistor.

18 • MAIN INPUT CORRECTION FUNCTION

It allows a custom correction of the main input reading throught the setting of four values: A1, B1, A2, B2. This function can be enabled selecting “Sens” +8 code (menu “Hrd”). Example: Sens = 1+8 = 9 for RTD sensor with input correction. If this function is applied to linear scales (50mv, 10V, 20mA, Pot), it is possible to reverse the scale. The four values are set in menu “Lin” as follows: A1 = St100, B1 = St01, A2 = St02, B2 = St03. Setting limits correspond to the prefixed scale (“LoS” ... “HiS” nel menù “InP”). The offset function (Parameter “oFt” menu “InP”) remains enabled. Limits: B1 always higher than A1; B1-A1 25% Should be at least 25%, of full scale of selected probe.

Example: Sens = 9, TyPE = 0 (Pt100 natural scale -200...+600), dPS = 0

LoS = 0, HiS = 400, oFt = 0 Reference point on the real curve: A1 = St00 = 50, B1 = St01 = 350 (B1-A1 = 300 greater than 25% of 800) Corresponding points on the adjusted curve: A2 = St02 = 120, B2 = St03 = 220

For a PTC input a specific calibration has to be requested

Before installation, please read the following advices:

• follow the indications of the manual scrupulously when making the connections to the instrument

• use a cable that is suitable for the ratings of voltage and current indicated in the technical specifications

• the instrument has no ON/OFF switch for the power, it operates immediately the supply is connected; for safety reasons, the devices permanently connected to power supply require ON/OFF switch with proper warking; the switch must be close to the unit and should be easily reachable by the user. A single switch can be connected to several units.

• if electrically NON-ISOLATED equipment is connected to the instrument (e.g. thermocouples), a ground wire must be connected to avoid that this connection is made through the machine

• if the instrument is used in applications where there is risk of injury to persons and damage to machines or materials, it is essential that it is used with an auxiliary alarm device. It is advisable to verify frequently that the alarm device is functional even during the normal operation of the equipment

• before using the instrument, it is the user's responsibility to ensure the correct instrument settings to avoid injury to persons or damage to objects and materials

• the instrument must NOT be used in environments where there could be the presence of dangerous atmospheres (inflammable or explosive); if the instrument is used with elements that operate in such atmospheres, they must be connected through an appropriate interface or safety barrier that conforms to the local safety regulations in force

• the instrument contains components that are sensitive to static electrical discharges and appropriate precautions must be taken before handling the electronic circuit boards if permanent damage to these components is to be prevented

Installation:

installation category II, pollution degree 2, double isolation

• the power supply wiring must be kept separate from that of inputs and outputs of the instrument; always check that the supply voltage corresponds to that indicated on the instrument label

• install the instrumentation separately from the relays and power switching devices

• in the same cabinet, do not install power contactors,, contactors, relays; thyristor power units “particularly if phase angle”; motors, etc...

• keep away from dust, humidity, corrosive gases and heat sources

• do not close the ventilation holes; the working temperature must be in the range 0...50°C. If the unit has faston terminals they must be of the protected and isolated type; if the unit has screw terminals it is necessary to fix the cable in pairs.

•

Power supply

: should be taken from an isolator with a fuse for the instrument section; the path of the supply wiring should be as direct as possible from the isolator to the instruments: the same supply should not be used to power relays, contactors, solenoid valves, etc.; if the voltage waveform is strongly distorted by thyristor switching units or by electric motors, it is recommended that an isolation transformer is used only for the instruments, connecting the screen to ground; it is important the electrical plant has a good ground connection, the voltage between neutral and ground must not exceed 1V and the resistance must be less than 6Ω; if the supply suffers large voltage swings, use a voltage stabiliser for the instrument supply; in the vicinity of high frequency generators or arc welders, use line filters; the power supply wiring must be kept separate from the that of the inputs and that of the outputs of the instruments; always check that the supply voltage corresponds to that indicated on the instrument label

•

Input and output connections:

for connecting analogue signals (TC, RTD) it is necessary to: physically separate the input wiring from that of the power supply wiring, from the wiring to the outputs and from power connections; use twisted and screened cables, with the screen connected to ground at only one point to use RC (resistor and capacitor in series) spark suppression components in parallel with inductive loads that operate in ac (contactors, solenoid valves, motors, fans, etc.) connected to the outputs of the instrument (

Note: all the capacitors must conform to the VDE standard (class x2) and

withstand a voltage of at least 220Vac. The resistor must be at least 2W

); fit a diode 1N4007 in parallel with the coil of inductive loads that operate in dc

SPIRAX-SARCO srl will not be held responsible for injury to persons or damage to objects and materials caused by mishandling, incorrect or erroneous use that is not in conformity with the instrument specifications.

WARNING: this symbol indicates danger. You can see it close the power supply circuit and the relay contacts that may be connected to high voltage.
