02P Controller 1 Introduction to the Controller and Manual 1.1 Using This Manual This manual aims to explain how to set up and operate the Carbolite 302P controller; it must be read in conjunction with the product main manual. Due to the complex nature of furnace control the use of technical terms throughout this manual is unavoidable. Explanations of these terms can be found in the ‘Glossary of Terms’ at the back of this manual. This manual covers the operation of: 1.

The Run key is used to: Start the program cycle when pressed for more than 1.5 seconds. Hold program cycle when pressed for more than 1.5 seconds while program is running. Stop program when pressed for more than 5 seconds while program is running or in hold.
Quick Start Guide 3.2 Selecting a program With basic operator mode selected OP.b (see section 3.6) press the function key once to display nprG in the lower display and the program number in the upper display. Select the required program number using the Down or Up After selection press the function key to store the parameter. 3.3 Starting the program Cycle To start the program the “Run” button must be pressed and held down for 1.5 seconds. After 1.
Quick Start Guide Op.b (Basic Operator Mode) is for running the program only. No other parameters are available. OP.E (Enhanced Mode) is for calibration and address assignment. Access to these is protected by security code =17. OP.P (Program editing mode).provides access to programming parameters. Access to these is protected by security code =4 To Enter OP.E (Enhanced mode) starting from Basic operator mode (OP.b). 1.

Programming 4 4.1 Programming Program Parameters In the basic operator mode – the below list of parameters are available. nPrg Meaning: Range: Available: Alterable: Seg Meaning: Range: Available: Alterable: rt. Meaning: Range: Available: Alterable: 10 number of the selected program from 1 to 3 fixed and password protected.
Programming r. rpt Meaning: Range: Available: Alterable: rpt… Meaning: Range: Available: Alterable: repetitions remaining to the end - from 0 to 9999 and then inF The figure shows the remaining repetitions after the current execution. For example 0 means that the program stops at the end of the current execution, while inF means that the device is set for endless repetitions.
Programming itSp Meaning: Range: Available: Alterable: Sp. 1 Meaning: Range: Available: Alterable: rr. 1 Meaning: Range: Available: Alterable: TH. 1 Meaning: Range: Available: Alterable: Sp.
Programming rpt Meaning: Range: Available: Alterable: Cet Meaning: Range: value) Available: Alterable: Note: number of program repetitions of the selected program - from 0 to 9999 and then inF The figure expresses the repetitions after the first execution. For example, if 2 is selected, the program will be executed 3 times, while inF means that the device is set for endless repetitions.
Programming 4.5 Programming Note: the normal 10 seconds timeout is removed while editing the program list. Program Number Press function to show nPrG lower display and the program number in the upper display. Press the Up or Down to choose the program number. Press to enter the selected program number. Password Protection program 1,2,3 After confirming selection of program 1,2 or 3, the word pass will be shown on the bottom display and ---- on the top display.
Programming Time Held (Dwell) After confirming selection, the display will then show, tH.1 lower display and the value in the upper display. Use the Up or Down to select a value for time held (dwell). Press to confirm Set Point 2 onwards After confirming selection, the display will then show, SP.2 lower display and the value in the upper display.
Programming 4.6 Program Review Programs 1,2,3,4 can be reviewed without password access while in the program level. Note: the normal 10 seconds timeout is removed while reviewing the program list. At the home display of the programming level, press function to show nPrG lower display and the program number in the upper display. Press the Up or Down to choose the program number. Press to select the required program number. Press the Up or Down to choose the program number.
Programming 4.8 Running a program Ensure the controller is in the basic operator mode parameter OP.b. Press function to show nPrG lower display and the program number in the upper display. Press the Up or Down to choose the program number. Press to enter to select the required program number. Table below shows the key presses to run a program Operation Action Indication To RUN a program Press for more than Run indicator = On 1.5 seconds. To HOLD a program Press for more than 1.5 seconds.

Programming 4.10 Program End Feature A program can end in one of two ways, either after the unit temperature has dropped below the cycle end threshold “CEt” which is the general method for most programs or after the last program repetition, if “CEt” has been set to “off”.
Programming 4.11 Program Example Once the password has been correctly entered the following sequence of entries creates the program shown graphically below. 1. Press until the lower display shows itSP . Select 10. 2. 3. 4. Press until the lower display shows SP. 1 . Select 600 Press until the lower display shows rr. 1 . Select 8 Press until the lower display shows t.H. 1 . Select 30 5. 6. 7. Press until the lower display shows SP. 2 . Select 900 Press until the lower display shows rr. 2 .
Programming 5 Enhanced Mode In enhanced mode the following parameters are available. CUSTOMER CALIBRATION TYPE SELECTION Identification code: CL.st Range: FACt Factory calibration C.CL1 1 point calibration C.CL2 2 point calibration C.CL3 2 coefficients calibration (a = 1 b = 0) (a = 1 b = OFSt) (a = x b = x) (a = SLOP b = OFSt) OFFSET (This parameter is always available but can be modified only if CL.ST = C.CL1, C.CL3) Identification code: OFSt Range: -199.9 / 199.
Programming 5.1 Customer Calibration The 302P controller is calibrated for life at manufacture, there may however be sensor or other system errors, which affect the accuracy of the measured temperature. Customer calibration can be used to compensate for these errors. Ensure the controller is in the Enhanced mode OP.E 1 Point Calibration CL.St = C.CL1 1 point calibration uses one offset value across the temperature range. Clear any previous coefficient adjustment. Press function until CL.
Programming Press function until CALH is displayed Press the Up or Down to enter the lower calibration temperature to which the offset is to be applied. Example. 1400°C Press function until OFS.H is displayed Press the Up or Down to enter the offset to be applied to the lower calibration temperature. Example: If at the calibrated temperature of 1400°C the controller is reading 1402.1, the offset will be -2.1°C (1402.1-1400 = 2.1) Press function to confirm selection.
Programming To adjust both offset and slope. Clear any previous coefficient adjustment. Press function until CL.St is shown in the lower display Press the Up or Down to C.CL3 in the upper display Press function to confirm selection and display OFSt Press the Up or Down to enter the offset value required across the temperature range (see above formula). This can be a negative or positive value.
