Pro-EC44 2-Loop Graphical Profile Controller & Recorder 9 Input Calibration & Multi-point Scaling User Calibration The process inputs can be adjusted to remove sensor errors or to match the characteristics of the attached process. For each loop, independent use of base (unadjusted), single point offset or two point calibration strategies are possible, as is the use of multi-point scaling for the displayed values of linear inputs.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Two Point Calibration This method is used where an error is not constant across the range. Separate offsets are applied at two points in the range to eliminate both “zero” and “span” errors. To use: 1. Measure and record the error at a low point in the process. 2. Measure and record the error at a high point in the process. 3. Go to the first two point input calibration screen. a. Enter the desired low point value as the Calibration Low PV value. b.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Multi-point Scaling If an input is connected to a linear input signal (mA, mV or VDC), multi-point scaling can be enabled. This allows the linearization of a non-linear signal. – see Input Configuration SubMenu Screens on page 46. The Scale Input Upper & Lower Limits define the values shown when the input is at its minimum and maximum values. Up to 15 breakpoints can scale the input vs. displayed value between these limits.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Performing a Calibration Check 1. Setup input 1 for the input signal type to be checked. 2. Power up the instrument and correctly connect the signal source. Leave powered up for at least five minutes for RTD and DC linear inputs, and at least 30 minutes for thermocouple inputs. 3. After the appropriate delay for stabilisation, check the calibration at a number of cardinal points by applying the appropriate input signal.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder 6. If the input is misconnected or an incorrect signal is applied, the calibration will be aborted and the values will not be altered. The display will show “Failed: Signal Too Small!” or “Failed: Signal Too Large!”. Correct the problem and repeat that phase before continuing. 7. Press R to select the next calibration phase. 8. Repeat this process for each input type until all the phases are calibrated.

Pro-EC44 2-Loop Graphical Profile Controller & Recorder 11 Cascade Control Applications with long time lags (e.g. with two or more capacities such as heated jackets) can be difficult to control with a single control loop. The solution is to split the process into two or more cascaded loops consisting of a Master and Slave(s) acting on a common actuator. Ideally, the slave loop’s natural response time should be at least 5 times faster than the master.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder the slave setpoint. The oil temperature is reduced towards the new slave setpoint. This continues until the system becomes balanced. The result is quicker, smoother control with the ability to cope with changes in the load. Overshoot is minimised and the jacket temperature is kept within acceptable tolerances. Normal Cascade Operation During operation, the master and slave are coupled together and. "Cascade" is displayed.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder To manually tune a cascade: 1. Select Cascade-Open from the Cascade Control menu, breaking the link between the master and slave loops. 2. Set the slave controller setpoint manually to the appropriate value for your application. 3. Tune the slave for relatively fast control (‘proportional only’ is often sufficient). 4. Select Cascade-Closed from the Cascade Control menu to link the master and slave loops, then tune the master/slave combination.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder 12 Ratio Control A ratio control loop is used where the quantity of one of the material is to be controlled in proportion to the measured quantity of a second material. The controller mixes the materials at the desired ratio by adjusting the flow of input 1. The flow of input 2 may be controlled separately, but is not controlled by the ratio control loop itself.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder attempts to make the physical ratio 10. With a setpoint of 1.03 it would attempt to make the ratio 10.3 for 3% excess air. The instantaneous (controlled) process value is calculated from the physical ratio, divided by SFac. Like the setpoint, this is displayed as relative value. E.g. if SFac is 10, with 59.5m3/h airflow measured at x1, 0.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder 13 Redundant Input If the 2nd universal input is fitted, the second input can be configured as a redundant input for the main process input. This increases process security by protecting against the possible loss of valuable product resulting from sensor failure. A second sensor is connected to input 2 so that if the main sensor fails, the instrument automatically switches to this backup or “redundant” sensor.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder 14 Valve Motor Drive / 3-Point Stepping Control When directly controlling the motor of a modulating valve or damper, set the Control Mode to VMD in configuration mode to enable the 3-point stepping Valve Motor Drive control algorithm. The term “3-point stepping” is used because there are 3 output states, open valve, close valve or stopped (no action).
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Position Feedback In VMD mode this instrument uses a boundless (open-loop) 3-point stepping algorithm. It does not require any kind of position feedback in order to correctly control the process and can therefore avoids problems associated with faulty feedback signals. However, where valve feedback is available it can still be displayed in a bar-graph as a percentage open (0 to 100%).
Pro-EC44 2-Loop Graphical Profile Controller & Recorder 15 Setpoint Sources The setpoint is the target value at which the instrument attempts to maintain the process variable. Each loop can have a Main “local” setpoint set from the keypad and an Alternate setpoint. Loop 1 Setpoint Sources Loop 1 can have a Main “local” setpoint set from the keypad and an Alternate setpoint.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder 16 Profiler This section covers the Profiler (or setpoint programmer) option. To confirm if profiling is enabled on your controller, refer to the Service & Product Info menu (see page 67). Introduction The Profiler feature allows the user to store up to 255 profile segments, shared between a maximum of 64 Profiles. Each profile controls the value of the setpoint over time; increasing, decreasing or holding their values as required.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder If the instrument also has the data recorder option, its real time clock (RTC) expands the profiling capabilities by adding Day & Time profile start options, releasing of hold segments at a specific time of day and changing the power fail recovery option to one based on the length of time the power has been off. These features are explained below and in the Profiler Setup and Profile Control menus (See pages 63 & 66).
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Note: If the join target has been deleted the profile sequence will abort and the last profiles abort action will apply. Two Loop Profiles If the instrument is configured to control two control loops, the setpoint of both loops can be maintained when profiling. Both setpoints are synchronised to a common segment timebase, but have independent target setpoints for each of the segments.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Loop-back Segments A Loop-back segment goes back to a specified segment in the current profile. This action is repeated for the required number of times (1 to 9999) before the profile continues onwards. More than one Loop Segment can be used in a profile, but they cannot cross.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder The Auto-Hold Feature There are independent auto-hold settings for each segment of each loop controlled by the profile. When utilised, auto-hold ensures that the profile and the actual processes remain synchronised. If the process does not closely match the setpoints (within the defined Hold Bands), the profile will be held until it returns within bounds. When Auto-Hold becomes active, the profile status is shown as “Held”.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Auto Hold on Ramps Held if Auto-Hold set to Above Setpoint or Band Process Variable Hold Band Ramp Setpoint (without AutoHold) Ramp Setpoint (with Auto-Hold) Held if Auto-Hold set to Below Setpoint or Band Figure 53. Auto-Hold On A Ramp Segment During a Ramp segment, the ramp is held at the current setpoint value while the process is outside of the hold band in the selected direction(s).
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Power/Signal Lost Recovery Actions If the power is cut or the input signal is lost while a profile is running, the instrument will use the defined Profile Recovery Method once the signal / power returns. The profile recovery method is set in the profile header. The possible profile recovery options are explained below.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Profile End Actions Once a running profile ends, that profiles’ Segment End Type defines the action taken by the instrument. If a sequence of profiles are joined together, the End Segment Type of the last profile in the sequence will be carried out when it completes. The end segment type is set in the final profile segment data. The possible profile end actions are explained below.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Profile Abort Actions If a running profile is forced to end early, the Profile Abort Action defines action taken by the instrument. The profile abort action is set in the profile header. If a profile sequence is forced to end early, the profile abort action of the current segment will be used. The possible abort options are explained below.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder 17 USB Interface The features in this section are available on models fitted with the optional USB Interface. Using the USB Port The USB Interface can be used to upload or download instrument settings to or from a USB memory stick. Easy configuration of multiple instruments is achieved by copying from one instrument to another, or by transferring data from the PC configuration software.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder 18 Data Recorder The optional Data Recorder allows the recording of process conditions to memory over time. It operates independently from the Trend Views. The recorder includes 1Mb of flash memory to store data when powered down and a real time clock (RTC) with a battery backup. CAUTION: Servicing of the Data Recorder/RTC circuit and replacement of the internal lithium battery should be carried out by only a trained technician.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Uploading Data Recordings can be transferred to a memory stick using the USB Port (See page 96). They can also be uploaded directly to the PC software via the configuration port or RS485/Ethernet communications if fitted. The data is stored in Comma Separated format (.csv) which can be opened and analysed with the optional PC software or opened directly into a spreadsheet. Many third party software programs can also import data in the .csv format.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder 19 Controller Tuning PID Sets & Gain Scheduling Up to 5 sets of PID tuning terms can be entered for each control loop, allowing the instrument to be pre-set for differing conditions. Each set has individual values for the following parameters: Primary Proportional Band; Secondary Proportional Band; On-Off Differential; Integral Time; Derivative time; Overlap/Deadband.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Automatic Tuning To automatically optimise the controllers tuning terms for the process, you can use Pre-Tune, Self-Tune or Auto Pre-Tune independently for each control loop. Note: Automatic tuning will not engage if either proportional band is set to On/Off control. Also, pre-tune (including an auto pre-tune attempt) will not engage if the setpoint is ramping, if a profile is running, or if the Process Variable is <5% of span from setpoint.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Pre-tune is selected from the automatic tuning menu. It will not engage if either primary or secondary outputs on a controller are set for On-Off control, during setpoint/profile ramping or if the process variable is less than 5% of the input span from the setpoint. Note: To pre-tune a cascade, first select “Cascade-Open” to tune the PID set(s) on the slave.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Manually Tuning Tuning Control Loops - PID with Primary Output only This technique balances the need to reach setpoint quickly, with the desire to limit setpoint overshoot at start-up or during process changes. It determines values for the primary proportional band and the integral and derivative time constants that allow the controller to give acceptable results in most applications that use a single control device.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Tuning Control Loops - PID with Primary & Secondary Outputs This tuning technique balances the need to reach setpoint quickly, with the desire to limit setpoint overshoot at start-up and during process changes. It determines values for the primary & secondary proportional bands, and the integral and derivative time constants that allow the controller to give acceptable results in most applications using dual control (e.g. Heat & Cool).
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Process Variable V = On-going Peak-to-Peak variation T = Time period of oscillation (minutes) dS = Maximum rate of rise dP = Maximum rate of fall R = Ratio Primary proportional band = Pb.P = Time Integral Time = T minutes Derivative Time = Secondary proportional band = R x Pb.P 5. Calculate and enter the PID control parameters (primary proportional band, integral time and derivative time) using the formulas shown, and observe the process. 6.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder 5. Follow the instructions in the diagram below. At each stage, allow sufficient settling time before moving on to the next stage. P.Pb is the Primary Proportional Band, Int.T is the Integral Time Constant. Process Variable START Apply power to the load Does the Time Tb PV continuously Yes oscillate? No Note the time Are the interval Ta Oscillations Yes decaying to zero? Multiply P.Pb No Note the period setting by 1.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Fine Tuning Small adjustments can be made to correct minor control problems. These examples assume reverse acting control (e.g. heating). Adjust accordingly for direct action. If they do not help solve the problem, re-tune the controller as detailed on the preceding sections. Note: When fine tuning the settings, only adjust one parameter at a time, and allow enough time for the process to settle into its new state each time you change a value.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Integral Time Constant To find the optimum integral time, decrease its value until the process becomes unstable, then increase it a little at a time, until stability has is restored. Induce a load disturbance or make a setpoint change to verify that the process stabilises. If not increase the value some more and re-test. If the response is too slow, decrease the integral time, but avoid instability.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Anti Wind-up If after fully optimising the tuning, there is an overshoot of the setpoint at start-up or in response to large setpoint changes, the reset wind-up inhibit point can be reduced to suspend integral action until the process is closer to setpoint. If set too low control deviation can occur (the process settles, but is offset above or below the setpoint). It this is observed, increase the value until the deviation error is removed.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder 20 Serial Communications Supported Protocols Communication with a Modbus RTU or Modbus TCP master device is possible if the appropriate communications module is fitted in option slot A. An RS485 Module is required for Modbus RTU. An Ethernet Module is required for Modbus TCP. The instrument can also act as “setpoint master” over RS485 for multi-zone applications.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Link Layer A query (data request or command) is transmitted from the Modbus Master to the Modbus Slave. The slave instrument assembles the reply to the master. This instrument is normally a slave device. It can only act as a master when being use as setpoint master controller to broadcast its setpoint to other controllers in a multi-zone application. MODBUS SLAVE MASTER INSTRUMENT QUERY RESPONSE Figure 62.

Pro-EC44 2-Loop Graphical Profile Controller & Recorder 21 Glossary Active Setpoint The term Active Setpoint is used to describe the currently selected setpoint when the instrument is in controller mode. Controllers can use the Main local setpoint and/or the Alternate Setpoint. Only one of the setpoints can be active at any time. During profiler control, the setpoint value is controlled by the profiler function.

Pro-EC44 2-Loop Graphical Profile Controller & Recorder Alarm Operation The process and control deviation alarm types are illustrated, together with the action of any associated outputs. Also refer to: Alarm Hysteresis; Alarm Inhibit; Alarm Types; Band Alarm Value; Deviation Alarm; Latching Relay; Logical Alarm Combinations; Loop Alarm; Process High Alarm and Process Low Alarm.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Alarm Types There are three basic alarm types, Process Alarms, Control Deviation Alarms and Event Based Alarms; plus some special condition alarms. Process Alarms are based on the absolute value of the Process Variable. If the PV rises above a high alarm value, or falls below a low alarm value, the alarm will become active. Control Deviation Alarms are based on the value of the Control Deviation error.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Auxiliary Input Offset Used to adjust the value of auxiliary input A if it provides a Remote Setpoint. Positive values are added to the remote setpoint value, negative values are subtracted, but the setpoint is still constrained by the setpoint limits. Also refer to: Auxiliary Input; Remote Setpoint; Scaled Input Upper Limit; Scaled Input Lower Limit Setpoint Lower Limit and Setpoint Upper Limit.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Calibration Adjustment or correction of the displayed values relative to the actual measured values. Refer to the User Calibration section of this manual for calibration use and instructions. Also refer to: Multi-point Scaling and Process Variable. Cascade Control Applications with long time lags (e.g. indirect heat via hot water jackets) can be difficult to control with a single control loop.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Control Configuration A sub-menu of the configuration menu used to adjust the parameters that relate to the control of the process (enabling control, auto/manual mode, control type and action, PID tuning terms, power limits, sensor break action, setpoint values and setpoint selection). Also refer to: Configuration Mode; Control Action; Control Enable; Local Setpoints; Manual Mode; PID; Setpoint Selection and Tuning.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Controller An instrument that controls one or more process control loops. For each control loop it compares a process variable to a target setpoint, and attempts to make the process maintain the setpoint value by applying a correcting variable (e.g. turning on a heater or dosing with alkali if controlling pH). The controller uses proportional (P, PI, PD o PID) or On-Off control.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Derivative Action Derivative action biases the proportional control output to compensate for the rate of change in the process variable. In a typical reverse acting application, derivative power is increased if the PV is rising, or decreased if it is falling. The combined proportional and derivative values adjust the correcting variable until the process stabilises, at which point derivative power becomes zero.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Display Configuration A sub-menu of configuration mode used to adjust the display (colour & contrast) and to enable access to selected parameters from operation mode. These are: Profile Control; Recorder Start/Stop; Recorder Status; Loop 1 & 2 Setpoint Select; Loop 1 & 2 Auto/Manual Select; Loop 1 & 2 Control Enable/Disable; Loop 1 & 2 Trend View; Loop 1 & 2 Setpoint Ramp Rate.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Indicator An instrument that displays process values, but lacks control features. Typically, alarm outputs are available that will activate at pre-set PV values. Also refer to: Controller; Limit Controller and Process Variable. Input Configuration A sub-menu of configuration mode, used to adjust the parameters that relate to the process and auxiliary inputs (type, engineering units, decimal places, scaling, filtering etc.).
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Invert Digital Input Digital inputs may be “inverted” so that they are active when off and inactive when on. This is useful if the signal applied to the chosen digital input function is reversed in relation the digital input action. Also refer to: Digital Input. Latching Output Alarm outputs can be set to latch on when they become active.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Local Setpoints Local setpoints are target setpoint values for the control loops that are entered by the user and stored in the controller. The value of local setpoints can be adjusted within the setpoint limits using the front keypad, or via a serial communications link. The instrument can has two setpoints for each control loop. The main local setpoint and an alternate setpoint.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Loop Alarm A loop alarm detects faults in the control feedback in the selected loop, by continuously monitoring the process variable response to the control outputs. If any alarm is setup as a loop alarm, it repeatedly checks if the control output is at saturation. If saturation is reached (0% or 100% power for single control type, -100% or +100% for dual control type), an internal timer is started.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Manual Loop Alarm Time The loop alarm time used is manually set whenever a loop alarm is defined to have a manually set time, or if P, PD or On-Off control is selected. This parameter determines the duration of the output saturation condition after which the loop alarm will be activated. Also refer to: Loop Alarm; On-Off Control; PD; PI and PID.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Cascade Control is another type of Master & Slave application where the slaves setpoint is set using the master controllers PID power output. Also refer to: Cascade Control; Linear Output; Retransmit Output; Remote Setpoint; Auxiliary Input Offset; Serial Communications and Setpoint. Modbus RTU Modbus RTU is the serial communications protocol used on instruments fitted with the RS485 Communications module into option slot A.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Modulating Valve A valve that can be positioned anywhere between fully closed and fully open by means of an incorporated motor. A typical application would be controlling temperature in a furnace heated by gas burners. The controller moves the valve to the desired position in order to control the gas flow.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder On-Off Differential A switching differential, centred about the setpoint, when using On-off control. Relay ‘chatter’ can be eliminated by proper adjustment of this parameter, but too large a value may increase process variable oscillation to unacceptable levels. On-off differential is also known as hysteresis or deadband.

Pro-EC44 2-Loop Graphical Profile Controller & Recorder PD Control Proportional and Derivative (PD) control combines proportional control with derivative action. It is similar to PID control, but without Integral action. Also refer to: Derivative; Integral; PID Control; Proportional Control and Tuning. PI Control Proportional and Integral Control (PI) combines proportional control with integral action. It is similar to PID Control, but without derivative action.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder If self-tune is enabled, it will be suspended while pre-tune runs. A pre-tune can be configured to run at every power up using the Auto Pre-Tune function. Refer to the Automatic Tuning section of this manual for full details. Also refer to: Auto Pre-Tune; PID; Process Variable; Self-Tune; and Tuning. Power Output Limits Used to limit the correcting variable. Normally the control algorithm can set these outputs to any value between 0% and 100%.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Process Variable (PV) Process Variables are the parameter to be controlled. Each control loop monitors its PV via one of the process inputs. PVs can be any type that can be measured by these circuits. Common types are thermocouple or RTD temperature probes, or pressure, level, flow etc from transducers that convert these parameters into DC linear input signals (e.g. 4 to 20mA).
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Profiler A profiler controls the value of the actual setpoint over time; increasing, decreasing or holding its value as required. This is used in applications where the rate of rise or fall of the process variable must be closely controlled, or where a value must be maintained for a period before moving to the next value. If the Profiler is fitted, up to 64 profiles can be created with 255 segments shared amongst them.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Recorder Configuration If the data recorder is fitted, a recorder configuration sub-menu is added to configuration mode. This is used to adjust the recorder parameters (recording mode, sample interval, recording triggers and values to record). Also refer to: Configuration Mode; and Data Recorder Recorder Option - Refer to Data Recorder. Recorder Menu If the data recorder is fitted, a recorder menu is added to the main menu.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Retransmit Output Scale Minimum Scales a linear output if it has been selected to retransmit a process or setpoint value. Retransmit scale minimum defines the point at which the output will be at its minimum value. E.g. for a 0 to 5V output, it is the PV or SP value corresponding to 0V.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Scaled Input Upper Limit For linear inputs, this parameter is used to scale the displayed process variable. It defines the displayed value when the process variable input is at its maximum value (e.g. if 4 to 20mA represents 0 to 14pH, this parameter should be set to 14).
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Sensor Break Pre-Set Power If a thermocouple or RTD is disconnected or breaks, the instrument detects the condition within 2 seconds, and sets the control loops output(s) to a value defined by the sensor break pre-set power parameter in the control configuration sub-menu. Process, band and deviation alarms behave as though the PV has gone high. Non-zero based linear inputs (e.g.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Setpoint Upper Limit The maximum value allowed for setpoints, adjustable within the scaled input limits. The value should be set below any level that might cause problems in the process. If the value is moved below the current value of a setpoint, that setpoint will automatically adjust to keep it within bounds. Also refer to: Input Span; Scaled Input Upper Limit; Setpoint and Setpoint Lower Limit.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Solid State Relay (SSR) An external device manufactured using two silicone controlled rectifiers in reverse parallel. SSRs can replace mechanical relays in most AC power applications. Some special SSRs can switch DC, but most cannot. As a solid-state device, an SSR does not suffer from contact degradation when switching electrical current. Much faster switching cycle times are also possible, leading to superior control.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Time Proportioning Control Time proportioning control is accomplished by cycling the output on and off during the prescribed cycle time, whenever the process variable is within the proportional band(s). The PID control algorithm determines the ratio of time (on vs. off) to achieve the level of the correcting variable required to remove the control deviation error. E.g.
Pro-EC44 2-Loop Graphical Profile Controller & Recorder Triac A small internal solid state relay, which can be used in place of a mechanical relay for low power AC switching (0.1 to 1 amp AC). Like a relay, the output is time proportioned. However, as solid-state devices, triacs do not suffer from contact degradation so much faster switching cycle times are possible, offering improved control and reliability. A snubber should be fitted across inductive loads to ensure reliable switch off the triac.
