Data Logger 5. Mounting MJK Chatter data logger is supplied in two different mounting versions: one for pipe mounting and one for wall mounting (mounting on wall or cabinet). 5.1 Pipe Mounting Necessary tools and parts: • Wedge set to fit pipe diameter • Socket spanner, 7 mm 1. Activate the Chatter unit(s) as described in section 9. Physical Activation on page 31. 2. Re-assemble the Chatter unit(s) as described in section 6.2 Wall Mounting on page 23. 3.
Data Logger 4. Secure stud bolts and wedges with a rubber band as shown below. 3. 4. Figure 4. Secure Stud Bolts and Wedges with a Rubber Band 5. Immerse the Chatter base in the pipe (if possible with the padlock pointing away from public view), and then pull the screws up until the wedges buckle in the pipe. Thereby the base is centered in the pipe, and the wedges will automatically level. 5. Figure 5. Center the Base 6. Screw the screws into the base, one by one without using any tool: 6.
Data Logger 7. Tighten the screws with a 7 mm spanner until the base is bolted onto the pipe: 7. Figure 7. Tighten the Screws with a Spanner From here on the base may not be moved, rotated or lifted! 8. Fasten the security wire of the pressure transmitter into the base before the pressure transmitter is placed inside the pipe. IMPORTANT: Use a large washer between the wire and the screw, so that the wire can not escape the base! 8. Figure 8. Fasten the Security Wire 5.
Data Logger 9. Remove the protective sleeving from the pressure transmitter and immerse the pressure transmitter in the pipe. 9. Figure 9. Immerse the Pressure Transmitter 10. Connect the pressure transmitter cable to the green Chatter top. IMPORTANT: The guide pins must align to ensure correct connection. 10. Figure 10.
Data Logger 11. Mount the Chatter top on the base by turning the top approx. 1 cm counter-clockwise, until the holes for the security padlock align. Expect a slight drag over the last few millimeters. This is due to the activation of the intruder alarm (a magnetic switch between top and base). 12. Mount the padlock (see figure below). 12. Figure 11. Mount the Padlock 13. Make sure that the green Chatter top is mounted and secured correctly: Right WRONG! Figure 12.
Data Logger 5.2 Wall Mounting 1. Mount the cabinet on the wall. 2. Connect the pressure transmitter(s) according to the example in section 8.1 MJK Chatter and MJK Expert Transmitter on page 29. 3. Connect the relevant in- and outputs. 4. Aktivate the Chatter unit(s) as described in section 9. Physical Activation on page 31. 5. Close the Chatter unit(s) as described in section 6.2 Wall Mounting on page 23.
Data Logger 6. Gain Access to SIM Card and Battery To change SIM card or battery in a Chatter unit, you must gain access to the unit’s circuit board. 6.1 Pipe Mounting 1. Open and remove the padlock that prevents unauthorized access to the Chatter unit. 2. Turn the green top approx. 1 cm counterclockwise (but do not lift it off!) 3. Leave the top on for about two minutes and then lift it off. This is to ensure a valid measurement and to allow time for sending an alarm to the server. 4.
Data Logger 9. Re-connect the pressure transmitter connector by turning the union clockwise. 10. Immerse the pressure transmitter into the pipe, and make sure that the cable and the security wire hang freely inside the pipe to ensure reliable measurements. 11. Mount the Chatter top at the base by turning the top approx. 1 cm counter-clockwise, until the holes for the security padlock align. Expect a slight drag over the last few millimeters.
Data Logger 6.2 Wall Mounting 1. Locate the Chatter unit: Figure 15. Wall Mounted Chatter in Custom-designed Cabinet 2. Loosen the four screws in the top cover to open the Chatter unit: Figure 16. Access to SIM Card - Wall Mounting 3. Insert SIM card or change battery as described in section 7. Internal Installation in the Chatter Unit on page 25. 4. Re-assemble the Chatter unit. IMPORTANT: Make sure that the leads do not get stuck or become squeezed between the cabinet and the cover. 5.

Data Logger 7. Internal Installation in the Chatter Unit 7.1 Inserting a SIM Card 1. Open the Chatter unit to gain accesss to the circuit board and the SIM card holder as described in section 6. Gain Access to SIM Card and Battery on page 21. 2. Open the SIM card holder by applying light pressure on the upper part (the lid) and at the same time dragging it towards the edge of the circuit board (here: to the right as indicated by the arrow): Figure 17.
Data Logger 3. Carefully insert the SIM card into the grooves that hold the card, and finally push it to the end stop. IMPORTANT: The SIM card must align with the grooves all the way down. Likewise the SIM card’s right, cut-off corner must point upwards and to the left (see arrow): Figure 19. SIM Card Correctly Inserted into the Grooves 4.
Data Logger 7.2 Battery Change 1. Open the Chatter unit to gain accesss to the circuit board and the battery as described in section 6. Gain Access to SIM Card and Battery on page 21. 2. Carefully push the battery sidewards to free it from the cable strap that holds the battery. Alternatively you can cut the cable strap (this requires, however, that you use a new strap for the new battery). 3. Disconnect the battery leads (red and black) from the Chatter circuit board by pulling out the “Batt” plug. 4.

MJK Expert™ 7070 Niveau Transmitter har de samme specifikationer som 7060-transmitteren, men har derudover en meget lille ydre diameter og er fremstillet i 316L syrefast, rustfrit stål. Transmitteren er specielt udviklet til niveaumålinger i boringer, brønde og drikkevandsbeholdere. Data Logger Transmitterne leveres med piezo-resistivt målesy8. Connection Examples stem og hhv.

Data Logger Appendix B. Calculation of Battery Lifetime The battery in the MJK Chatter unit is of the lithium-trionyl-ion-trotyl type which is characterized by a high energy density, a low self-discharge, and a long lifetime. The energy density is 17 Ah nominal and guarantied 15 Ah (15.000 mAh). Depending on the use of the Chatter unit you can estimate the battery lifetime. The Chatter will, depending on the setup, execute one control call every 25th. hour (if a shorter interval has not been selected).
Data Logger Calculation Example 1 Chatter basic consumption per day (fixed) = 1.0 No. of logs per day @sensor consump.=2mA 1 x 0.1 = 0.1 No. of logs per day @sensor consump. =4mA x 0.2 = No. of event logs per day @sensor consump.=2mA x 0.1 = No. of event logs per day @sensor consump. =4mA x 0.2 = No. of calls per day 1 x 3 = 3.0 No. of alarm calls per day 0.01 x 3 = 0.03 Consumption per day (total): 4.
Data Logger Calculation Example 3 Chatter basic consumption per day (fixed) = No. of logs per day @sensor consump.=2mA 24 x 0.1 = No. of logs per day @sensor consump. =4mA x 0.2 = No. of event logs per day @sensor consump.=2mA 180 x 0.1 = No. of event logs per day @sensor consump. =4mA x 0.2 = No. of calls per day 2 x 3 = No. of alarm calls per day x 3 = Consumption per day (total): Battery lifetime in days: Battery lifetime in months: Battery lifetime in years: Appendix B.

Data Logger Appendix C. Calculation of WLD- and Ref. Datum The following examples illustrate how you can calculate the water level datum (WLD) in relation to the cable length and the reference datum of a bore. Example: A bore has the following characteristics: • Reference datum: 34.76 m (the level at which the Chatter base rests on the pipe/bore head) • Cable length: 25.0 m • Sensor depth: 24.9 m (cable length - 10 cm) • Measurement from DB: 7.
Data Logger The water level datum (WLD) in this example: 34.76 - 24.9 + 7.65 => 17.51 m The following figures/numbers for the bore are required as entries to the data base to achieve a valid calculation of the water level datum. Sensor depth from top of bore 1. Sensor depth from the top of the bore = total cable length – 10cm. 2. “Total cable length” is printed on a label near the cable connector (example: cable length = 11.86 m). 3.
