4 Mounting 4 Mounting Switch off source 4.1 General instructions The source container is part of the measuring system. In case the source container is already equipped with an active isotope, the source container must be locked before mounting. Danger: Before mounting; make sure that the source is securely closed. Use a padlock to secure the source container in the closed condition and prevent it from being inadvertently opened.
4 Mounting Installation position 4.2 Mounting instructions Note: Along with the planning, our specialists will analyse the conditions of the measurement loop to dimension the radiation source (isotope) accordingly. You get a "Source Sizing" document specifying the required source activity and containing all relevant mounting information for your measuring point. You must follow the instructions of this "Source Sizing" document in addition to the following mounting instructions.
4 Mounting Summation To measure the level in very high vessels, multiple instruments can be cascaded. Cascading means that two or several instruments are connected which can together cover a longer measuring range. You can find the exact number of Slaves in the Safety Manual. L2 h L1 1 Fig.
4 Mounting Vessel with heat insulation On vessels with temperature insulation, the sensor and the source container should be preferably mounted outside of the tank insulation. Fig. 5: Level measurement on a heated vessel with heat insulation If this is not possible, make sure that there is a sufficiently large cut-out in the tank insulation for mounting the sensor and the source container. Make sure that the max. ambient temperature of the sensor is not exceeded. Protection against heat If the max.
5 Connecting to power supply 5 Connecting to power supply Safety instructions 5.1 Preparing the connection Always keep in mind the following safety instructions: • • Connect only in the complete absence of line voltage If overvoltage surges are expected, overvoltage arresters should be installed Voltage supply Power supply and digital bus cable via separate two-wire connection cables. Power is supplied via the H1 voltage supply.
5 Connecting to power supply T-distributor, the screen of the short stub to the sensor must not be connected to ground potential or to another cable screen. The cable screens to the power supply unit and to the next distributor must be connected to each other and also connected to ground potential via a ceramic capacitor (e.g. 1 nF, 1500 V). Low-frequency potential equalisation currents are thus suppressed, but the protective effect against high frequency interference signals remains.
5 Connecting to power supply 6. Insert the wire ends into the round openings of the terminals according to the wiring plan Information: Solid cores as well as flexible cores with cable end sleeves are inserted directly into the terminal openings. In case of flexible cores without end sleeves, press the rectangular lock opening with a small screwdriver; the terminal opening is freed. When the screwdriver is released, the terminal opening closes again. 7.

6 Set up with the display and adjustment module 6 Set up with the display and adjustment module Mount/Dismount display and adjustment module 6.1 Insert display and adjustment module The display and adjustment module can be inserted into the sensor and removed again at any time. It is not necessary to interrupt the power supply. Proceed as follows: 1. Unscrew the small housing cover 2.
6 Set up with the display and adjustment module 6.2 Adjustment system 1 2 Fig.
6 Set up with the display and adjustment module Information: In this operating instructions manual, the instrument-specific parameters are described. Further general parameters are described in the operating instructions manual "Display and adjustment module". Instrument start Caution: During the first setup or after an instrument reset the instrument starts with preset standard values. These value are not suitable for your application and must be replaced by real values.
6 Set up with the display and adjustment module Through this selection, the sensitivity of the sensor is adapted perfectly to the isotope. The normal reduction of the emitter activity is hence considered through the radioactive decay. The SOLITRAC 31 requires this information of the automatic decay compensation. This ensures an interference-free measurement over the complete life time of the gamma emitter - an annual recalibration is not necessary.
6 Set up with the display and adjustment module These settings influence the current output of the sensor. Enter in the menu window "Max. process value" the max. level (full), for example in "m". This corresponds to an output current of 20 mA. Enter in the menu window "Min. process value" the min. level (empty), for example in "m". This corresponds to an output current of 4 mA. Setup - Linearization In this menu item you can carry out the adjustment of the sensor.
6 Set up with the display and adjustment module Select "Linearization - New" to enter the first point. Select "Determine count rate" to enter the first point. The determination of the actual count rate lasts 2 minutes. After the count rate has been determined, you can accept the value (ct/s). The count rate is stated in ct/s. This is the number of counts per second, i.e. the measured radioactive radiation dose actually reaching the sensor. Enter now the corresponding level (m).
6 Set up with the display and adjustment module Because you have already set the background radiation to 0 in the menu item: "Setup/Background radiation", the measured pulse rate must be around 0 ct/s. Show diagram This menu item is only available if a linearization was already carried out. Show table In this menu item you can show the individual value pairs of the linearization. Linearization - Delete You can also delete individual linearization points.
6 Set up with the display and adjustment module Setup - Real value correction If you know the level at a certain height, you can enter in this menu item the determined real level to correct the measured value. The function shifts the linearization curve to this determined point. With this procedure the measurement can be adapted exactly to the conditions in the vessel. Setup - Relay In this menu item you can activate the relay output and determine its function as well as the switching points.
6 Set up with the display and adjustment module Caution: Independent of the selected reference value, the relay will deenergize in case of failure. Lock setup - adjustment With this menu item you safeguard the sensor parameters against unauthorized or unintentional modifications. This menu item is described in the operating instructions manual "Display and adjustment module". Display Display - Language With this parameter you can change the display language.
6 Set up with the display and adjustment module Diagnosis - Simulation In this menu item you can simulate measured values via the current output. This allows the signal path to be tested, e.g. through downstream indicating instruments or the input card of the control system. Note: To carry out a simulation with the display and adjustment module, you have to switch on the simulation switch on the electronics module (switch position 1).
6 Set up with the display and adjustment module The following reset functions are available: Basic settings: Resetting of the parameter adjustments to default values at the time of shipment. Order-specific settings are deleted. Default settings: Resetting of the parameter adjustment like under "Basic settings". In addition, special parameters are reset to default values. Order-specific settings are deleted.

6 Set up with the display and adjustment module This menu item enables adaptation of the sensor to the requested application. You can choose between the following applications: "Level", "Point level" or "Summation Slave". Setup - Outputs In this menu item you can activate the function of the current output. When the output is activated, the instrument remains in its function as a Slave, but the 4 … 20 mA output of the SOLITRAC 31 can be also used als single instrument.
6 Set up with the display and adjustment module Diagnosis: Information, for example, of device status, peak value, simulation Additional adjustments: Instrument unit, reset, date/time, copying function Info: Instrument name, hardware and software version, date of manufacture, instrument features Procedure Check if the correct language is already set for the display. If not, you can change the language in the menu item "Display/Language". Start with the setup of SOLITRAC 31.
6 Set up with the display and adjustment module Setup - Background radiation The natural radiation on earth influences the accuracy of the measurement. With this menu item the natural background radiation can be faded out. For this purpose, the SOLITRAC 31 measures the natural background radiation and sets the pulse rate to zero. In the future, the pulse rate from this background radiation will be automatically deducted from the total pulse rate.
6 Set up with the display and adjustment module Empty the vessel until the sensor is uncovered. For this enter the requested pulse rate manually or let the rate be determined by SOLITRAC 31. Automatic determination of the pulse rate should be given preference. The pulse rate is entered in ct/s. This is the number of counts per second, i.e. the measured gamma radiation reaching the sensor.
6 Set up with the display and adjustment module You thus get the min. pulse rate (ct/s) for the "covered" adjustment. Enter the requested pulse rate manually or let the rate be determined by SOLITRAC 31. Automatic determination of the pulse rate should be given preference. You can enter the adjustment point (ct/s) manually. You can let the adjustment point be determined by SOLITRAC 31.
6 Set up with the display and adjustment module Overfill protection = the relay will deenergise (safe condition) when the max. level is reached. Dry run protection = the relay will deenergise (safe condition) when the min. level is reached. Make sure that you have selected the correct characteristics. See menu item "Setup/Current output mode". Lock setup - adjustment With this menu item you safeguard the sensor parameters against unauthorized or unintentional modifications.
6 Set up with the display and adjustment module The greater the difference in the pulse rate between covered and uncovered status, the greater the differential value (Delta I) and the more reliable the measurement. The automatically calculated damping is also oriented around the Delta I value. The higher the value, the lower the damping. A Delta I value below 10 % is an indication for a critical measurement.
6 Set up with the display and adjustment module Additional adjustments Additional settings - PIN In this menu item, the PIN is permanently activated/deactivated. Thus you protect the sensor data against unauthorized access and unintended changes. The default setting of the PIN is 0000. This parameter is described in the operating instructions manual "Display and adjustment module". Additional adjustments Date Time In this menu item you can set the actual date and time.
