5 English Please observe that /4100U is intended always be* installed in a standpipe (column/bypass/ stilling well). A standpipe is commonly used when: Servicing the /4100U There is highly conductive foam in the tank. The liquid is very turbulent or agitated. /4100U Coaxial with or without HMI does not need any change of setting operate, unless used in CO 2. Presetting: 4 ma : length mm (4 in.) 20 ma: 120 mm (5 in.) s /4100U is designed specifically measure liquid level in the most commonly used refrigerants, including R744 (CO 2 ), R717(ammonia), HCFC, HFC and non corrosive gases/liquids. Basic data /4100U is a passive 2-wire 4-20 ma sensor that is loop powered. Supply Voltage V d.c. min/max. value for a max. output of 22 ma at the terminal Load RL [Ω] ((Uext -14 V)/20 ma).

NPT (Further details in the Technical Brochure) Mechanical Installation Preparations prior Mechanical Installation Disassemble the Signal Converter from the Mechanical process connection (use 5 mm hex key, see fig. 7). Fit the red protection cover on p of the Mechanical process connection protect it againt any moisture or dirt paticles. Content supplied (fig 1) Signal Converter (with or without HMI) Mechanical process connection with 5 m (197 in.) Ø2 mm (0.08 in.) stainless wire Tube(s) Bag with: End Connecr (incl. 3 mm set screws.) 3 mm set crews (1 set screw pr. tube) Red cover protect Mechanical process connection, before Signal converter is mounted Setting label. Assembly of the segmented coaxial probe Please observe that the stainless steel wire is not permanently creased or kinked. 1. Take the end of the stainless wire and feed it through the center hole of the plastic spacer located at the p of each tube (see fig. 2). Feed the entire length of the stainless wire through the tube and out at the botm. If more than one tube; repeat the steps. 2. Assemble the segments of tube and (see fig. 3). Use a 17 mm open-end wrench tighten the assembled parts. 3. If more than one tube; repeat the steps (see fig. 3). 4. Prior assemble, disassemble signal converter and mechanical process connection, and fit red protection cap at mechanical process connection. Thread the fully assembled tube on the mechanical process connection. 5. Lock each tube by tightening the set screw with a 3 mm hex key (see fig. 3). 6. Pull the stainless wire through the end connecr (see fig.4). 7. Attach the end connecr the botm of the fully assembled tube. Tighten the set screw with a 3 mm hex key (see fig. 4). 8. Pull the end of the stainless steel wire extending from the end connecr with pliers (see fig. 4) ensure that the tension in the signal cable is correct. Tighten the 2 set screws with a 3 mm hex key lock the stainless wire. 9. Cut the stainless wire about 20 mm (0.8 in.) below the end connecr (see fig. 5). 10. Measure the probe length (without the signal converter) before fitting the assembled probe in the standpipe (see fig. 6). Use a rque wrench tighten the mechanical process connection (fig. 1, item 2) 120 Nm (89 lb/ft). If facry setting needs adjustment length, scale 4 ma and 20 ma for HMI Quick Setup. length: See probe length on product label or measure probe length (see fig. 6). Scale 4 ma: (for max. measuring range) = dead zone (see fig. 6) Scale 20 ma:(for max. measuring range:) = Top dead zone (see fig. 6) Example () Given conditions: length: 1200 mm : CO 2, 35 C The gas constant Er is always adjusted from the Quick Setup length: = 1200 mm SCALE 4 ma setting for max. measuring range: = length (1200 mm) dead zone (see fig. 6) (170 mm) = 1030 mm (40.9 in.) SCALE 20 ma Setting for Max. Measuring range: = Top dead zone (see fig. 6) = 120 mm (4.7 in.) From page 8: parameter = 1.02 How mount the /4100U Converter (see fig 7) 1. Using a 5-mm hex key, loosen the setscrew in the Signal Converter. 2. Slide the Signal Converter down until it rests on the mechanical process connection. 3. Turn the Signal Converter the wanted position and tighten the set screw with a 5 mm Hexagon key Electrical installation/connection Output terminals (fig. 8 and 9): 1. Current output 2. Current output + 3. Grounding terminal Electrical installation procedure 1. Use a 2.5 mm Allen wrench loosen the cover sp. 2. Remove the terminal compartment cover from the housing. 3. Do not disconnect the wire from the terminal compartment cover. Put the terminal compartment cover adjacent the housing. 4. Connect the wires the device. Tighten the cable entry glands. 5. Attach the terminal compartment cover the housing. 6. Use a 2.5 mm Allen wrench tighten the cover sp. Note: The signal converter can be programmed with or without mechanical process connecr assembled. Start up: Connect the converter the power supply. Energize the converter. Devices with the HMI display option only: After 10 seconds the screen will display "Starting up". After 20 seconds the screen will display the software version numbers. After 30 seconds the default screen (fig. 13) will appear. Precausions when changing from AKS 41/41U the /4100U: Please note: The AKS 41/41U can be used with a.c. and d.c. supply, but the /4100U can only be used with a d.c. supply. Follow the instructions in fig. 10. Connecting controller or PLC Follow the instructions in fig. 11 or 12. Note: The current output will be set 3.6 ma whenever the /4100 detects an error like Marker 1, 2 or 3 (see page 4). Quick Setup A/S (AC-MCI/MWA), DKRCI.PI.SC0.E5.02 / 520H5658 5
