The signal can be used to simultaneously activate a self-cleaning with the master. Interrupting the operation via an external signal You can temporarily interrupt the automatic operation of the analyzer via an external signal at the "DIO" module. This can be useful if no sample is available in your process at certain times, e.g. during a cleaning phase. 66 Endress+Hauser Liquiline System CA80COD Operation The following information is processed at the binary inputs or output at the binary outputs: • Binary inputs: Signal for process access: The analyzer can only perform activities that require sample (measurement, calibration, cleaning) when the signal is active. The time and the sequence of activities correspond to the settings in the setup. All activities that require sample are delayed as long as the signal is inactive. • Binary outputs: – Signal Measurement active: Indicates that a measurement is currently running. The signal is not active in the event of a calibration or cleaning. – Signal Sample required: The signal is active for a configurable time before every activity that requires sample.

Assign a binary output to the selected measuring channel: select Binary input x:y. Controlling the measurement start time via an external signal You can temporarily interrupt the automatic operation of the analyzer via an external signal at the "DIO" module. You can also use this signal to specifically start individual measurements. In this way, you can specify the time of the measurements using your external control system. For this purpose, connect the Signal for process access to a binary input of the "DIO" module and set the starting time of the measurements to Continuous . A measurement starts immediately as soon as the signal at the binary input is active. The only exception is if a calibration or cleaning is due on the basis of the set time intervals: in this case, these activities are performed first of all and then the measurement follows immediately afterwards. Where necessary, connect the signal Measurement active to a binary output to identify when the measurement actually begins. If you do not want any more measurements after the end of the first measurement, you have to deactivate the Signal for process access while the measurement is still running.

Assign Unipolar- to the output to which an actuator that can decrease the measured value is connected. To output the manipulated variable of a two-sided controller, positive manipulated variables and negative manipulated variables generally have to be output to different actuators, as most actuators are able to influence the process in one direction only (not in both). For this purpose, the instrument splits the bipolar manipulated variable y into two unipolar manipulated variables, y+ and y‐. Only the two unipolar manipulated variable parts are available for selection for outputting to modulated relays. If outputting the values via a current output, you also have the possibility of outputting the bipolar manipulated variable y to one current output only (split range). 10.5.2 Alarm relay and optional relays The basic version of the device always has one alarm relay. Additional relays are also available depending on the version of the device. The following functions can be output via a relay: • Limit switch status • Controller manipulated variable for controlling an actuator • Diagnostic messages • Status of a cleaning function in order to control a pump or a valve You can assign a relay to multiple inputs in order to clean several sensors with just one cleaning unit, for example.

Maximum number of pulses per minute The controller calculates the pulse duration based on this setting. Outputting diagnostic messages via the relay If a relay is defined as a diagnostic relay (Function = Diagnostics), it works in the "failsafe mode". This means that the relay is always energized ("normally closed", n.c.) in the basic state if an error is not present. In this way it can also indicate a drop in voltage, for example. The alarm relay always works in the failsafe mode. You can output two categories of diagnostic messages via the relay: • Diagnostic messages from one of the 4 Namur classes • Diagnostic messages which you have individually assigned to the relay output A message is individually assigned to the relay output at 2 specific points in the menu: • Menu/Setup/General settings/Extended setup/Diagnostics settings/Diag. behavior (device-specific messages) • Menu/Setup/Inputs//Extended setup/Diagnostics settings/Diag. behavior (sensor-specific messages) Before being able to assign the relay output to a special message in Diag. behavior you must first configure Outputs/Relay x:y or /Alarm relay/Function = Diagnostics . 78 Endress+Hauser Liquiline System CA80COD Operation Function = Diagnostics Function Options Info Operating mode Options • as assigned • Namur M • Namur S • Namur C • Namur F as assigned If this option is selected, the diagnostic messages which you have individually assigned to the relay are output via the relay.

The difference between the set point w and the controlled variable (measured value) X results in the control deviation which is filtered by a neutral zone. The neutral zone is used to suppress control deviations (e) that are too small. The control deviation thus filtered is now fed to the actual PID controller which divides into three parts based on the P (proportional), I (integral) and D (derivative) values (top-down). The integral section (middle) also comprises an anti‐windup mechanism for limiting the integrator. A low-pass filter is added to the D‐section to damp hard D‐terms in the manipulated variable. The sum of the 3 sections results in the internal controller manipulated variable which is limited according to the settings (for PID‐2s to ‐100% to +100%). The graphic does not illustrate a downstream filter for limiting the rate of change of the manipulated variable (can be configured in the menu in Max y change rate). In the menu do not configure the gain Kp. Instead configure the reciprocal value, the proportional band Xp (Kp=1/Xp). Configuration Make the following decisions when configuring a controller: • (1) What type of process can your process be assigned to? → Process type • (2) Should it be possible to influence the measured variable (controlled variable) in one direction or in both directions? One-sided or two-sided controller, → Controller type • (3) What should be the controlled variable (sensor, measured value)? → Controlled variable • (4) Do you have a disturbance variable that should be active at the controller output? → Disturbance variable 86 Endress+Hauser Liquiline System CA80COD Operation • (5) Define the parameters for the controller: – Set point, → Setpoint – Neutral zone, → Xn – Proportional band, → Xp – Integral action time (I-value), → Tn – Derivative action time (D-value), → Tv • (6) What should the controller do in the event of a hold (measured error, sensor replacement, cleaning etc.)? – Pause or continue with dosing? →Hold behavior/Manipulated Variable – At the end of a hold, continue or restart the control loop (affects I‐value)? →Hold behavior/State • (7) How should the actuator be triggered? – Unipolar+: Assign this setting to the output for an actuator which can increase the measured value. – Unipolar-: Assign this setting to the output for an actuator which can decrease the measured value. – Bipolar: Select this setting if you want to output the manipulated variable via one current output only (split range). • (8) Configure the outputs and switch on the controller.

Factory setting Inline Batch process The medium is in a closed system. The task of the control system is to dose in such a way that the measured value (controlled variable) changes from its start value to its target value. No more dosing is needed once the set point has been reached and the system is stable. If the target value is overshot, a two-sided control system can compensate for this. In the case of 2-sided batch control systems, a neutral zone is used/configured to suppress oscillations around the set point. In-line process In an in-line process, the control system works with the medium flowing by in the process. Here, the controller has the task of using the manipulated variable to set a mixture ratio between the medium and dosing agent such that the resulting measured variable corresponds to the set point. The properties and volume of the medium flow can change at any time and the controller has to react to these changes on a continuous basis. If the flow rate and medium remain constant, the manipulated variable can also assume a fixed value once the process has settled. Since the control process is never "finished" here, this type of control is also referred to as continuous control. mixture of both process types can often be found in practice: the semi‐batch process. Depending on the  Aratio between the flow and the container volume, this arrangement behaves either like a batch process or an in-line process. Controller type Selection • PID 1-sided • PID 2-sided Depending on the actuator connected, you influence the process in just one direction (e.g. heating) or in both directions (e.g. heating and cooling). Factory setting PID 2-sided A 2‐sided controller can output a manipulated variable in the range from ‐100% to +100%, i.e. the manipulated variable is bipolar. The manipulated variable is positive if the controller should increase the process value. In the case of a pure P-controller, this means that the value of the controlled variable x is smaller than the set point w. On the other hand, the manipulated variable is negative if the process value should be decreased. The value for x is greater than the set point w. y Xp Xp +100 % xw -100 %  59 88 Relationship y = (w-x)/Xp Endress+Hauser Liquiline System CA80COD Operation Menu/Setup/Additional functions/Controller 1 ... 2 Function Options Info Effective direction Selection • Direct • Reverse In what direction should the controller influence the measured value? • The measured value should increase as a result of dosing (e.g. heating) → Reverse • The measured value should decrease as a result of dosing (e.g. cooling) → Direct Controller type = PID 1-sided Factory setting Reverse A 1‐sided controller has a unipolar manipulated variable, i.e. it can only influence the process in one direction.

In some circumstances, strong fluctuations are possible. In the case of a settled control system in which the flow rate is suddenly halved, it is desirable that the dosed quantity from the controller is also directly halved. In order to achieve this type of "flow-rate‐proportional" dosing, this task is not left to the I‐component of the controller, but rather one enters the (to be measured) flow rate as disturbance variable z multiplicative at the controller output. z + z0 w 1 1+Tw s - 1 zp er + y x x Strictly speaking, feedforward control involves an open-loop control system, since its effect is not measured directly. That means that the feed flow is directed exclusively forward. Hence the designation "feedforward control." For the additive feedforward control that is alternatively available in the device, the (standardized) disturbance variable is added to the controller manipulated variable. This enables you to set up a type of variable base load dosing. The standardization of the disturbance variable is required both for multiplicative and for additive feedforward control and is done using parameters Z0 (zero point) and Zp (proportional band): zn = (z ‐ z0)/zp zn +100 % 0% z0 z zP -100 % Example Flowmeter with measuring range 0 to 200 m3/ h The controller would currently dose 100% without feedforward control. The feedforward control should be configured such that at z = 200m3/h, the controller still doses at 100% (zn = 1). If the flow rate drops, the dosing rate should be reduced, and at a flow rate of less than 4 m3/h, dosing should stop entirely (zn = 0). → Select the zero point z0 = 4 m3/h and the proportional band Zp= 196 m3/h.

Diagnostic information on local display Up-to-date diagnostic events are displayed along with their status category, diagnostic code and short text. Clicking on the navigator lets you retrieve more information and tips on remedial measures. 11.3 Diagnostic information via web browser The same information as for the local display is available via the web server. 11.4 Diagnostic information via fieldbus Diagnostic events, status signals and more information are transmitted according to the definitions and technical capability of the respective fieldbus systems. 11.5 Adapting the diagnostic information 11.5.1 Classification of diagnostic messages In the DIAG/Diagnostics list menu you can find more detailed information on the current diagnostic messages displayed. Endress+Hauser 105 Diagnostics and troubleshooting Liquiline System CA80COD In accordance with Namur specification NE 107, the diagnostic messages are characterized by: • Message number • Error category (letter in front of the message number) – F = (Failure) a malfunction has been detected The measured value of the affected channel is no longer reliable. The cause of the malfunction is to be found in the measuring point. Any control system connected should be set to manual mode. – C = (Function check), (no error) Maintenance work is being performed on the device. Wait until the work has been completed. – S = (Out of specification), the measuring point is being operated outside its specification Operation is still possible. However, you run the risk of increased wear, shorter operating life or lower measurement accuracy. The cause of the problem is to be found outside the measuring point. – M = (Maintenance required), action should be taken as soon as possible The device still measures correctly. Immediate measures are not necessary. However, proper maintenance efforts would prevent a possible malfunction in the future. • Message text If you contact the Service Department, please cite the message number only. Since you can individually change the assignment of an error to an error category, the Service Department cannot use this information. 11.5.2 Adapting the diagnostic behavior All the diagnostic messages are assigned to specific error categories at the factory. Since other settings might be preferred depending on the application, error categories and the effect errors have on the measuring point can be configured individually. Furthermore, every diagnostic message can be disabled. Example Diagnostic message 531 Logbook fullappears on the display. You want to change this message so that an error is not shown on the display for example. 1. For analyzer-specific diagnostic messages, select Menu/Setup/Analyzer/Extended setup/Diagnostics settings/Diag. behavior and for sensor-related messages, select Menu/Setup/Inputs//Extended setup/Diagnostics settings/Diag. behavior. 2. Select the diagnostic message and press the navigator button. 3. Decide: (a) Should the message be deactivated? (Diagnostics message = Off) (b) Do you want to change the error category?(Status signal) (c) Should an error current be output? (Error current = On) (d) Do you want to trigger a cleaning program? (Cleaning program) 4. Example: You deactivate the message.  The message is no longer displayed. In the DIAG menu, the message appears as Past message. Possible settings The list of diagnostic messages displayed depends on the path selected. There are devicespecific messages, and messages that depend on what sensor is connected. 106 Endress+Hauser Liquiline System CA80COD Diagnostics and troubleshooting Menu/Setup/../Extended setup/Diagnostics settings/Diag. behavior Function Options List of diagnostic messages Select the message to be changed. Only then can you make the settings for this message. Diag. code Read only Diagnostic message Selection • Off • On Factory setting Depends on the Diag. code Error current Selection • Off • On Factory setting Depends on the Diag. code Status signal Info Selection • Maintenance (M) • Out of specification (S) • Function check (C) • Failure (F) You can deactivate or reactivate a diagnostic message here. Deactivating means: • No error message in the measuring mode • No error current at the current output Decide whether an error current should be output at the current output if the diagnostic message display is activated. In the event of general device errors, the error current is switched to all the current outputs. In the event of channel-specific errors, the error current is only switched to the current output in question. The messages are divided into different error categories in accordance with NAMUR NE 107. Decide whether you want to change a status signal assignment for your application. Factory setting Depends on the Diag. code Diag. output Cleaning program Selection • None • Binary outputs • Alarm relay • Relay1 to n (depends on the device version) You can use this function to select an output to which the diagnostic message should be assigned. Factory setting None For sensors with the Memosens protocol: Selection • None • Cleaning 1 ... 4 Decide whether the diagnostic message should trigger a cleaning program. Factory setting None Detail information Endress+Hauser Read only alarm relay is always available,  An regardless of the device version. Other relays are optional. Before you can assign the message to an output: Configure one of the output types mentioned as follows: Menu/Setup/Outputs/(Alarm relay or Binary output or relay)/Function = Diagnostics and Operating mode = as assigned. You can define cleaning programs under: Menu/Setup/Additional functions/Cleaning. Here you can find more information on the diagnostic message and instructions on how to resolve the problem. 107 Diagnostics and troubleshooting Liquiline System CA80COD 11.6 Overview of diagnostic information 11.6.1 Device-specific, general diagnostic messages No. Message Factory settings S 1) D 2) Tests or remedial action F 3) 202 Selftest active F On Off Wait for self-test to be finished 216 Hold active C On Off Output values and status of the channel are on hold 241 Firmware failure F On On Internal device error 242 Firmware incomp.
