In such instances, the manufacturer does not accept any liability for the device. 6 Commissioning 6.1 Function check Warning! • Check that all connections have been established correctly. • Make sure that the supply voltage matches the voltage indicated on the nameplate! 6.2 Configuring the device address The address must always be configured for a PROFIBUS-PA device. If the address is not configured correctly, the measuring device is not recognized by the process control system. All devices are delivered from the factory with the address 126. You can use this address to check the function of the device and to connect to a PROFIBUS-PA network. You then have to change this address to integrate additional devices. The following methods are available for configuring the address: ! 1. By means of PROFIBUS communication 2. By means of hardware settings (DIL switch). Note! • Valid device addresses are in the range from 0 to 126. • Each address may only be assigned once in a PROFIBUS-PA network. 6.2.1 Configuring the device address by means of PROFIBUS communication You configure the address by means of the "Set Slave Adr" service. ! Note! You can only configure the address via the bus if DIL switch 8 is set to "On" (= factory setting). 6.2.2 Configuring the device address by means of hardware (DIL switch) To configure the device address, you must open the housing and change the keys of the DIL switch on the CPU module. You set the address (0 to 126) using keys 1-7. To do so, you must set key 8 to the "Off" position (= hardware setting). 28 Endress+Hauser Liquiline M CM42 Commissioning You can set any number between 0 and 126 by using binary code, e.g.: • 0: • 1 (20=1): • 18 (21+24=2+16=18): 6.3 Device master and type files The device master file (GSD) is needed to configure a PROFIBUS-DP network. The GSD (simple text file) contains information on the data transmission rate the device supports or what digital information the PLC receives from the device and in what format. ! Note! Every device is given an ID number by the PROFIBUS User Organization (PNO). The name of the device master file (GSD) is derived from this. For Endress+Hauser, the ID number always starts with "15XX".

Maintenance Specialist • Read and, sometimes, write access in the PARAM and DIAG menus • Read and write access in the calibration menu Admin status: • Read and write access in all menus • Change the access authorization for other user groups Note! If you are logged in as the "Specialist" (= Administrator), you can change the access authorization of all other user groups: 1. Select a software function for which you want to assign authorization to, or take authorization from, another user group. 2. Press and hold down the navigator button for at least 3 seconds. The display shows all the user groups and the current access authorization to the function selected. 3. Use the navigator to change the authorization in question and confirm with "OK". 4. Make a note of the changes in your operating logbook or similar. 6.6 Calibration Calibration is necessary: • At initial commissioning • After replacing a sensor • After periods of standstill • At sensible, process-dependent intervals1) 1) Depending on the process conditions, the intervals can range from several times daily to once quarterly. Endress+Hauser 33 Commissioning Liquiline M CM42 6.6.1 Types of calibration Select the calibration type in the menu "PARAM"/"Sensor..."/"Cal. Settings"/"Type of calibration" or in the Quick Setup. • Two-point calibration – With automatic buffer recognition (only pH): You select the buffer type (e.g. DIN 19266). The device automatically recognizes the buffer during calibration. – With fixed buffer (only pH): You select two buffer solutions from the menu. – Manual:2) You enter the buffer values during calibration. • Single-point calibration – You enter an offset. • Numeric input: – You enter the slope, zeropoint and temperature (only pH). – You enter the mV value (for ORP). • Grab sample calibration – You take a sample of the medium. The device determines a measured value while you analyze the sample in the laboratory. Then you enter the laboratory measured value. The device calibrates on the basis of the laboratory value. 6.6.2 Calibrate Proceed as follows to calibrate the sensor: 1. Go through the menu "Param"/"Quick Setup" completely3). 2. Remove the sensor from the process. 3. Clean the sensor. 4. Press the soft key for "CAL". 5. Follow the instructions in the menu. 6. Finish calibrating by switching back to the measuring mode. 7. Install the sensor back into the process. Your measuring point is now ready for operation. ! 2) 3) 34 Note! • If calibration is aborted using ESC, or if the calibration is faulty, the system continues to use the original calibration data. A calibration error is shown as plain text on the display. • Any offset set is automatically deleted after accepting the calibration. Not available during initial commissioning if you are working with the factory settings. Only for initial commissioning Endress+Hauser Liquiline M CM42 7 Maintenance Maintenance Clean the front of the housing with usual commercial cleaning agents.
