3 User part 1 Introduction MIKROTHERM MT600-_D is a temperature/process controller with 1 input for measurement, 1 control / auxiliary input and 2 outputs. Buying a new controller, see the chapter Installation and configuration of controller If you have the device installed from the producer of device, see the chapter Final User Final User If you are a final user, you will get the device in the customised operation and you can view and change only the parameters that you need for your own work. There is a special part for you in manual User Part. If you are a new user of the device, focus on the following chapters: Basic terms this chapter explains the key functions, modes of controller, info and error messages.. In the whole manual you will be referred to the terms explained in this chapter. User level In this level you can scroll through mode of controller, configure and set selected parameters, etc Tips for operation and troubleshooting you will find in the chapter Tips. Installation and configuration of controller For installation and controller s configuration the configuration and service part of the manual is assigned. It is assumed that you know the basic operation of device described in the chapter Basic terms and you are authorised for the installation and you know how to set up the device. Information on the installation of the device you will find in chapter Installation Wiring is described in chapter Wiring Guidelines at first power-up are in chapter Putting into operation For further information on the operation see chapter Configuration level and Tips for configuration For service worker it is convenient to find out the options in the chapter Service level After the complete set up of device it is recommended to write down parameter values in table on page 35. There is a blank table for writing of programmes on the same page. 3

4 User part 2 Basic terms The controller can be used for the control of temperature or other quantity ( for simple description the temperature will be used further). To avoid problems in the operation of device the user must be able to manage its operation. 2.1 Operation and description of the controller Before you start, it is necessary to explain the principals for control. On the front panel board you can see 2 displays, 3 control lights and 4 keys. The device is set and configured via menu. The features of keys and displays is shown on the following picture: functions of indicators indicates actual process value in Basic MODE when set it shows parameter value upper display lower display indicates the state of control output indicates the state of alarm,/signal output indicates set point value in basic MODE. when set it shows type of parameter diodemode, indicate run of programme key function Short-term press: listing in menu confirming of set values Long-term press (3 seconds): entry to operation level upper display lower display Short-term press: return to Basic MODE Long-term press: starting, ending of decreasing of set value press 2keys together (for 3 seconds) to change levels from lower to higher ones ( configuration, service) increasing of set value The tables for menu and the descriptions of parameters are in the following chapters. 4

5 User part Setting parameters In the user part the setting of parameters is described in the table of this format: Confirm Display Procedure Return Confirm, indicates the key, with which you go through menu and confirm the parameters to be set Display, shows the data displayed on lower display Procedure, meaning of parameter and procedure how to set it Return, return to basic mode without editing/setting the parameter Important: You can view only the parameters which are necessary. Parameters are selected and adjusted with arrow keys If the parameter is not confirmed by the key stated in column Confirm, it is not set Returning to basic mode by the key Return, then the parameter is not set During automatic return to basic mode the parameter is not set. The controller returns to basic mode automatically if no key is pressed for 60 seconds and automatic return is allowed (in configuration level, menu SYS, parameter Aret = on). 2.2 Modes of controller Mode of controller is indicated by the diode MODE, see page 4. The 3 following modes will be often used in the description of the controller. Basic, diode MODE is not lit, the controller s output is turned OFF or the controller maintains the process value at the set point value. Running a programme, diode MODE is lit, the controller runs by a programme. Setting, the upper display appears the actual value, the lower display appears the type of parameter. 2.3 Information and error messages Information and error messages are indicated only in basic mode. Information messages, upper display ---- error of input sensor or the input is not set. Information messages, lower display Aut automatic setting/autotuning of PID parameters is running, see page 12.

12 User part 5 Tips In this chapter the tips for operating and setting of the controller and the troubleshooting some problems are described for an operator. 5.1 Autotuning automatic setting of PID parameters The controller is fitted with the function that sets automatically PID parameters. Procedure of starting autotuning: The controller must switch the control output, it means the control output must not be turned OFF (in basic MODE there must not be on lower display off). You can start the automatic optimization with parameter Aut = on. You will find parameter in operation level, menu GlbL or you can set it accessible in user menu. The controller explores the characteristics of system from switching ON/OFF on the output and determines optimal PID parameters. It can cause an overshoot and large fluctuations. Important: Autotuning can not take effect in ON/OFF control, i.e. ot1 = ht2 or CL2. Autotune set point value for autotunig is set by the actual process value, by the actual set point value and by the parameter AtSP. It is calculated this way: Autotune set point value = actual process value + (actual set point value - actual process value) x AtSP / 100. Parameter AtSP is found in configuration level, menu SYS, see page Automatic and manual operation Automatic operation for controlling requires feedback (in other words the measurement of process value and control actions). The operator adjusts set point value and the controller operates the output power that is supplied to the system. At manual operation for controlling the operator adjusts the request output power. Setting of automatic or manual operation In operation level, select automatic or manual type of operation via parameter A-M. If A-M = Auto, automatic operation is set, if A-M = Man, manual operation is set. 12

13 Important: User part At manual operation the controller can not influence the output power that is only adjusted by the operator. The behaviour of system is then fully under operator` s control. At manual operation the writing Man blinks on lower display. The controller remains in the selected type of operation even after the voltage supply interruption. 5.3 Simple programme The controller enables the control in time by a simple programme rate and soak. set point value SP2 hold rate time Setup parameters of programme Parameter hold (hour.minute) determines the time period of soak at set point value SP2 ( C). Parameter rate determines the ramp rate to the set point value SP2. The scale of parameter rate can be selected in configuration level, menu SYS, parameter rps ( C/hour. or C/min.). Starting and ending a programme You can start or end a programme by double pressing. When in a programme the control diode MODE is lit, on lower display blinks ProG. Important: When editing a programme the actual parameters are only accessible ( parameter rate need not be displayed). The time remaining to the end of soak can be viewed with parameter tend. The supply voltage interruption does not break the programme. After the resumption of the supply voltage the controller resumes in a programme automatically. 13

14 Configuration and service part 6 Installation The controller is designed to be mounted to the panel cutout. Slide the controller into the cutout and fix it with 2 flanges, that are supplied with the controller. The installation requires the access to the back of the panel. Mounting dimmensions Width x height x overall length: 72 x 72 x 159 mm (including terminalboard). Behind panel length: 150 mm (including terminalboard). Cutout in the panel: 66 x 67 mm (width x height). The thickness of panel: max. 12 mm. Mounting Make the panel cutout. Slide the controller into the panel cutout. Insert the flanges from backward, slide the hooks into the holes for holding on both sides of the controller, with the heads of the screws in the direction from the panel. Tighten the screws firmly on the flanges. The controller is installed, then its wiring follows, see page

15 7 Wiring Configuration and service part To avoid potential electric shock, use safety practices laid down by national standards when wiring and connecting this unit to a power source. Failure to do so could result in such damage, and / or injury. The wiring must be done only by the authorised person. When you carry out the wiring it is necessary to fix the outer connecting wires in the manner so to avoid the reduction of insulation between the category supply voltage and safe voltage in case of loosening a wire from the terminal. It is inevitable to fix wires of supply voltage (terminal 1, 2), output 1 (terminal 3, 4), output 2 (terminal 5, 6), as close as possible to the terminals of the controller. Supply voltage Before you connect the unit to a supply power source, check the level of supply voltage. 230VAC 50Hz Po 200 ma

16 Configuration and service part Thermocouple and RTD input When you connect the thermocouple you need to use the compensating or thermocouple lead of the corresponding type. It is necessary to connect it with respect to polarity or 3-wire connection of RTD platinum sensor. 3 wire connection compensates perfectly the resistance of wires, if all 3 wires have the same electrical resistance Process input Voltage input, input impedance 10 kω Current input, input impedance 40 Ω U + - I + 16

26 Configuration and service part 11 Tips for configuration In this chapter the tips for setting the device will be presented Measurement The right selection, the installation, the wiring, the location of sensor in the equipment and the corresponding setting of parameters of the controller have the essential importance for the correct function. Configuration parameters of input for measurement are in configuration level, menu InP1. Setting of input sensor Set the corresponding input sensor in parameter In1. You will find the survey of input sensors in the chapter Technical parameters, see page 36. You can set the position of decimal point by parameter dec1. You can set the displaying without decimal point or with 1 decimal figure for thermal sensors, and for process sensors you can set without decimal point, with 1 decimal figure or with 2 decimal figures. You can set the limit for set point value in configuration level, menu StPt, parameters SP1L and SP1h, see page 22. Important: Thermocouple and RTD inputs have the detection of improperly wired sensor. When the sensor is open or broken, the control output will turn OFF, the alarm output is activated, the signal output is deactivated.. Process inputs do not have the detection of improperly wired sensor. Input filter If the process value is distorted by interference, you can use the digital filter. The more the filter coefficient is Ftr1, the more the filter smooths the input signal. When Ftr1 = off the filter is turned OFF. process value without filter with filter time 26 time

27 Configuration and service part Measurement range of process inputs In configuration level, menu InP1, with the parameters rl1, rh1 and dec1 you can set the limits for the measurement range of the process inputs. Example of setting of process input: You want to display the input signal 4 to 20 ma in the range 6.0 to Set dec1 = 0.0, rl1 = 6.0 a rh1 = The distribution between values 6.0 and 24.0 will be linear. Displayed process value ma 20 ma input signal 11.2 Control, the control output You can select in the controller ON/OFF (2 state) or PID controlling for heating or cooling. If PID controlling is set, you can use the autotuning function for finding optimal PID parameters, see page 12 and the power limit function, see page 29. Parameters for configuration of the control output are in configuration level, menu out1. ON/OFF control ON/OFF control is selected by setting ot1 = ht2 (heating control) or CL2 (cooling control). It is used for less exacting application. It is not possible to achieve zero hysteresis value on principle. The process value rises and drops about set point value in the characteristic way. Process value Set point value hysteresis The state of the control output ON time OFF time 27

28 Configuration and service part PID control PID control is selected by setting ot1 = ht (heating) or CL (cooling). It provides the precise control. For the correct function of the controller, however, it is necessary to set properly PID parameters. Autotuning for setting of PID parameters is described on page 12. PID parameters have the following meaning: Pb proportional band, is set in measured units. It is the band about the set point value in which the controller keeps the temperature. It integral factor, in minutes. Integral factor compensates the loss of system. A low integral value causes a fast integrating action. de derivative factor, in minutes. Derivative responses to fast changes and tries to react against them. The more value is, the more derivative factor reacts. If the control output is 2 state (ON/OFF) (relay or SSR), the power is (given in %) transferred to the output with so called pulse width modulation. In each time cycle (parameter Ct1, that is in operation level, menu out1) the control output is switched ON once and once OFF. The more the power is necessary, the wider the width of switching is. The output responses are illustrated in the third part of the drawing. Process value setpoint value Output power 100 % time the state of the control output ON time Time cycle OFF þdv Example of pulse width modulation of the output: Time cycle is 10 seconds, the power requested is 30%. The output is ON for 3 seconds and OFF for 7 seconds. Time cycle is 10 seconds, the power requested is 5%. The output is ON for 0,5 second and OFF for 9,5 seconds. 28

29 Important: Configuration and service part The duration of time cycle has the influence on the quality of control. The longer the cycle is, the less the quality of control is. If the electromechanical unit (relay, switching contactor) is used for the control output, the duration of time cycle must be set longer with regard to lifetime of switch. Power limit function You can improve the quality of control by limiting of the output power. Process value Power limit high PLu1 SPL1 Power limit low PLd1 time Example how to use the power limit function: When rising at set point value the big overshoot occurs. One of possible solution is the power limit in the vicinity of set point value. The procedure is the following: Find out the power supplied to the stable system. Set SPL1 on the value by several o C less than set point value. Set power limit PLd1 to 100%. Set power limit Plu1 approx. by 10 to 20% higher than the power supplied to the stable system Alarm, signalling The second output (output 2) can be used for alarm or signalling. The parameters for the output configuration are in configuration level, menu out2, you will find setting of alarm / signal limits o2lo and o2hi in operation level, menu out2. Setting of alarm / signal output Set the function with parameter ot2 : ot2 = no, the output is not used. ot2 = ALPr, alarm defined by absolute value. ot2 = ALdE, alarm defined by the deviation from set point value. ot2 = SGPr, signalling defined by absolute value. ot2 = SGdE, signalling defined by the deviation from set point value. 29

30 Important: Configuration and service part Relay in standby MODE means active alarm, deactivated signalling. When controller is switched OFF, error of sensor, error of controller the alarm is active. When controller is OFF, sensor error, error of controller the signalling is deactivated. Alarm / signalling, absolute value: process value Active Deactivated o2hi Active o2lo time Alarm / signalling, the deviation from set point value: o2hi process value Active Set point value Deactivated o2lo Active time Temporary, permanent (latched) alarm / signalling Alarm / signalling can be temporary (LAt2 = off) or permanent (LAt2 = on). Temporary alarm / signalling will turn automatically off when the alarm / signal condition is over. Turn OFF permanent(latched) alarm / signalling when the alarm / signal condition is over by the function o2of that is found in operation level. This function can be set also in user menu. Permanent alarm / signalling is also turned off after the supply voltage interruption. Silencing of alarm / signalling Silencing of alarm / signalling can be used to disable alarm / signalling at the startup rising to the set point value. This state should not be evaluated as error because the system is not yet stable. This function is set with parameter SIL2: SIL2 = off, function is not active SIL2 = on, alarm / signalling can be activated after the process value at the startup rising reached the allowed range for the first time (between alarm limits). 30

31 Configuration and service part process value Active When startup alarm/signalling is deactivated Deactivated Active time Active sides of alarm / signalling With parameters o2sd you can choose the active side of alarm / signalling: o2sd = LohI, both sides(limits) are active. o2sd = hi, only high alarm / signal side(limit) is active. o2sd = Lo, only low alarm / signal side(limit) is active Digital input Digital input of model MT600- _D-_-0 0 serves for the operator (or superior - MASTER system, for example programmable automatic) to control the chosen function of the controller via external switch or DC voltage. Setting Digital input is initiated with parameter EI in configuration level, menu EIn. These functions are available: no digital input is not used otof turning the control output OFF LoC locking of the keyboard on the front panel IdSP switching over between actual and idle set point value ProG starting/ending a programme You can set the logic assessment for input signal with parameter EISG. Lo input is turned ON with low level hi input is turned ON with high level rise rise edge changes the state FALL fall edge changes the state input signal high level 31

32 Configuration and service part 11.5 Programme The controller can be programmed in time by a simple programme. This function is selected in configuration level, menu StPt, parameter SP1C: SP1C = SP, the controller maintains the process at set point value, however, it is possible to use the ramp function. SP1C = PG1, PG2, PG3, PG4, one of the following programmes is used: set point value SP2 SP1C= PG1 hold set point value SP2 SP1C= PG2 hold rate SP1 SP1 time time set point value SP2 SP1C= PG3 hold set point value SP2 SP1C= PG4 hold rate output is OFF output is OFF time time Guaranteed time of soak You can ensure the guaranteed time of soak by parameter rdy. This parameter defines the permitted deviation from the set point SP2. When the process value reaches the range of the permitted deviation the time of soak is triggered. Parameter rdy is found in configuration level, menu SYS. SP2 Range rdy Set point value Process value Time of soak is triggerred time 32

33 Configuration and service part 11.6 Setting of user menu User menu, see page 8, provides a user with the simplest access for viewing and setting parameters. The list of parameters that will be present in user menu, and their sequence are optionally set. You can create user menu in configuration level, menu KEYb, see page 23. Example how to create user menu: You want to place on the first (1.) position of user menu parameter Aut, on 2. position PID parameters (Pb1, It1, ) out1. Proceed as follows: Set parameter StP1 = Aut. Set parameter Stp2 = out1. 3 and 4 positions are used, for the parameters StP3 and StP4 set no. You will look over the result in user menu How to lock menu and parameters If your controller is configured and set you can lock: The setting of set point value SP1. The access to operation level.. The access to configuration level and protect it with password. You will find the parameters for locking in configuration level, menu LoC, see page 24. Important: You can simplify the setting of the controller for user by locking single items. By locking single items you will prevent a user from inappropriate actions to setting of the controller Ramp function Ramp function will ensure the reaching of the set point value SP1 by linearization rising. In this manner you can protect the system or material that must not be exposed to large changes of temperature. You can set the ramp function with parameter ramp that is found in configuration level, menu SYS. Set the scale for the ramp function with parameter rp S. SP1 Set point value linearized rising time 33

34 Important: Configuration and service part The ramp function is possible to use only for maintaining the process value at the set point value (SP1C = SP). The ramp function is activated only after the powering the controller up at start rising before the set point value is reached for the first time. When the ramp function is active, on lower display the writing ramp blinks. 34
