1. COMPLIANCE Compliance with FCC rules Please note that this equipment generates, uses and can radiate radio frequency energy. This equipment has been tested and has been found to comply with the limits of a Class A computing device pursuant to Subpart J of Part 15 of FCC rules. These rules are designed to provide reasonable protection against interference when equipment is operated in a commercial environment.
2. INTRODUCTION This manual describes how this product works and how to get the most out of it in terms of performance. The SW-D weighing indicator may be used to build a water-proof digital scale to specification IP69K. It has similar specifications and functions as an indicator of the SW series. Please refer to the instruction manual for the SW supplied with the SW-D. 3.
4. UNPACKING Unpack the indicator carefully and keep the packing material if you are likely to transport the indicator again in the future. When unpacking, check whether all of the following items are included: Model label (1083013259-2) Indicator To be attached. SW-D CAPACITY SECTION Write the scale’s ratings, etc.. SW-D Set up instructions (this manual) SW series Instruction manual Main power cord Please confirm that the main power type is correct for your local voltage and receptacle.
5. INSTALLATION and PRECAUTIONS 5.1. Precautions for Installing the Indicator DANGER Ground the indicator so that the user will not be subjected an electric shock. Do not handle the main power cord with wet hands. The AC plug is not water-resistant. Install it in an area where it does not get wet. Even when the optional sealed lead acid (SLA) battery (HC-02i) is used, be sure to prevent the AC plug from getting wet. Do not install the indicator where there is flammable or corrosive gas present.
4. Solder the wires to the pin contacts of the connector. A 5 m or less load cell cable is recommended as the SW-D uses a 4 wire system (no remote sensing). SHIELD (EXC-) Negative Excitation (SIG-) Negative Signal In (SIG+) Positive Signal In (EXC+) Positive Excitation Load cell Load cell cable 5 SHIELD 4 EXC- 3 SIG- 2 SIG+ 1 EXC+ Pin contacts 5. Tighten the cable clamp locking nut to secure the load cell cable. 6.
Example of calculation: In the case of designing a scale with a capacity of 60 kg and minimum division of 0.005 kg, using one load cell with a rated capacity of 100 kg and rated output of 1 mV/V: Rated capacity of Load cell: Rated output: Minimum division: Excitation voltage: Number of load cells: A = 100 kg B = 1 mV/V 5000 × 1 × 0.005 = 0.25 > 0.2 d = 0.005 kg 100 × 1 E = 5000 mV n=1 Therefore, there is no problem with this design. 5-4.

DESCRIPTION OF EACH PART Display Load cell panel Main power cord Earth terminal Load cell connector LED display STABLE indicator NET indicator LO OK HI pcs ZERO indicator Weighing units g STABLE NET kg ZERO oz lb ON/OFF key ON/OFF SAMPLE PRINT UNITS ZERO TARE SAMPLE key PRINT key UNITS key ZERO key TARE key Symbols Symbol Description STABLE ○ Turns on when the weight value is stable. NET ○ Turns on when the NET weight is displayed. (The tare operation is in progress.
Key Description ON/OFF key Turns the power ON or OFF. When turned ON, the scale will be automatically set to zero (power-on zero). To turn the power OFF, press and hold the key. Note: If pressing the key does not turn the power ON immediately, keep pressing the key. SAMPLE key In the counting mode (“pcs”), goes to the unit weight storing mode. Press and hold to go to the comparator value setting mode. PRINT key Outputs the weight value to the printer.
7. CALIBRATION When calibrating, refer to this set up instructions. (The contents of SW instruction manual are not the same as this set up instructions.) 7.1. Items of the calibration mode The calibration mode has the following three functions. • Setting of the weighing capacity, minimum division, and decimal point position. • Gravity acceleration correction • Calibration using a weight How to enter the calibration mode 1.
The chart below shows the relation between each item and the key operation in the calibration mode. Weighing mode Press the (CAL) switch Setting of the weighing capacity, minimum division, and decimal point Gravity acceleration correction Calibration using a weight Setting of the CF function Press or Power OFF Press the UNITS key to select an item and press the TARE key to execute it. To exit from the calibration mode, press the ZERO1 key or the CAL switch. The indicator turns the power off.
7.2. Setting of the weighing capacity / minimum division / decimal point position Set the weighing capacity, minimum division, and decimal point position. Be sure to perform these setting first when connecting to a load cell (base unit). The indicator does not require setting each time, if nothing is to be changed. 1．Refer to “7.1. Items of the calibration mode”, to enter the calibration mode. The indicator displays “Cal5et”. 2.
7.3. Gravity acceleration correction When the scale is first used or has been moved to another location, it should be calibrated using a calibration weight. But if a calibration weight is not available, the gravity acceleration correction will compensate the scale. Change the gravity acceleration value stored in the scale to the value of the area where the scale will be used. Refer to the gravity acceleration map at the end of this manual.
7.4. Calibration using a weight This function adjusts the scale (indicator) for accurate weighing. Calibration must be done when the SW-D is initially connected to a load cell (base unit) or the combination is changed. Calibration may also be required according the changes in the environment. When the scale (indicator) has been moved. When the ambient environment has significantly changed. For regular calibration.
7. Place the calibration weight with the same value as displayed on the weighing pan, and wait for the STABLE indicator to turn on. 8. Press the TARE key. The scale calibrates SPAN and “end” is displayed. After displaying “Cal”, the setting is complete. Press 9. To finish the setting procedure, press the ZERO1 key or the CAL switch. The indicator turns the power off.
8. SETTING FUNCTIONS OR UNITS FOR USE The indicator has CF function settings to specify the indicator performance. After installing the indicator, the indicator does not require resetting or changing of this CF function as far as it is used normally. If you want to maintain only the needed units, set using this function. The parameters set in the CF function settings and unit setting are maintained even if the power is turned OFF. Item Parameter 8.1. Setting of the CF function 1. Refer to “7.1.
8.2. Setting unit for use 1．Refer to “7.1. Items of the calibration”, to enter the calibration mode. The indicator displays “Cal5et”. 2. Press the MODE 3. Press the TARE Press three times key three times to display “Cf”. key to display the setting item. Press 4. To proceed without storing this setting item, press the ZERO key. After displaying “Unit”, proceed to the unit setting mode. (Display example: “1110000 pcs”) Press 5. Select the unit to be used, using the following keys.

9. OPTIONS For details of HC-02i, SW-03, and SW-04, refer to the “OPTIONS” in the SW series instruction manual. 9.1. SW-11 Display stand / Wall-mount SW-11 provides the function as a display stand or a wall-mount for the SW-D. Attaching to SW-11 1. Attach the SW-11 to the display using the four screws provided. 2. Adjust the display angle using the two clamps on the SW-11. After loosening the two clamps on the SW-11, adjust the display angle, and retighten the two clamps. Clamp SW-11 3.
10. MAINTENANCE 10.1. Notes on maintenance Do not disassemble the indicator. Contact your local A&D dealer if the indicator needs service or repair. Use the original packaging for transportation. Do not use organic solvents to clean the indicator. Use a warm lint free cloth dampened with a mild detergent. Calibrate the indicator periodically to maintain the weighing accuracy. 10.2. Error codes Overload error Indicates that an object beyond the weighing capacity has been placed on the weighing pan.
