FAILURE TO DO SO COULD RESULT IN BODILY HARM OR DAMAGE THE UNIT. CAUTION Permit only qualified persons to service the instrument Before connecting or disconnecting any components, remove the power. Failure to observe these precautions could result in bodily harm or damage to or destruction of the equipment. The weighing indicator is a precision electronic instrument, handle it carefully. Do not install the scale in direct sunlight. Verify the local voltage and receptacle type are correct for the scale. Only use original adaptor, other could cause damage to the scale. Pluggable equipment must be installed near an easily accessible socket outlet. Avoid unstable power sources. Do not use near large users of electricity such as welding equipment or large motors. Avoid sudden temperature changes, vibration, wind and water. Avoid heavy RF noise. Keep the indicator clean - 2 - TBWS Washdown Bench Scales Technical Manual 1.

INTRODUCTION The TBWS series weighing indicator that amplifies signals from a load cell, converts it to digital data and displays it as a mass value. It is suitable for general weighing or more specialized applications such as check weighing, animal weighing and accumulation applications. It can connect the indicator to a printer or a PC. Large LCD with white LED back light displays - 4 - TBWS Washdown Bench Scales Technical Manual 3. INSTALLATION 3.1Unpacking When you receive the Indicator, inspect it to make sure that it is not damaged and that all are parts are included: Remove the Indicator from the carton. Remove the protective covering. Store the packaging to use if you need to transport the scale later. Inspect the indicator for damage. Make sure all components are included. 1. Indicator 2. Manual 3. Indicator holder (Optional) 4. Load cell Output connecter (Optional) 5. RS-232 Output Connecter (Optional) 3.2 Installation Place the Indicator on a table or use indicator holder to connect with stand. Connect the plat form load cell cable to the indicator load cell connecter. Load cell connecter is locating back side of the indicator. Connect the adaptor pin to the indicator adaptor jack. Adaptor jack is locating, back side of the indicator. Adaptor connects into your AC power socket. Pluggable equipment must be installed near an easily accessible socket outlet with a protective ground/ earth contact. Turn on the On/Off key. If you want to turn off, press the key again. Display will show the scale capacity and will be starting self-checking. After self-checking, display will be come to normal weighing mode. Warm-up time of 15 minutes stabilizes the measured values after switching on. Calibrate with exact calibration weights, minimum 1/3 of the scale capacity should be used for calibration. For calibration see details in parameter. Then you can start your operation. - 5 - TBWS Washdown Bench Scales Technical Manual 3.3 Load cell connections Connect the load cell cables to the terminal as shown below. 7Pin Connection Pin 1 Signal Pin 2 Signal + Pin 3 Exc Pin 4 Exc + Pin 5 Sen Pin 6 Sen + Pin 7 Shield It can connect four 350 ohm load cells. The load cell drive voltage is 5V DC ±5% between Excitation + and Excitation -. 3.4 Connect Adaptor and Charging To charge the battery insert the adaptor pin to jack. Simply plug the adaptor into the main power. The scale does not need to be turned on. The battery should be charged for 8 hours for full capacity. In lower left side of the keyboard is an LED to indicate the status of battery charging. When the scale is plugged into the main power the internal battery will be recharged. If the LED is green, the battery is fully charged. If it is red, the battery is nearly out and if yellow, the battery is being charged. Do not use any other type of power adaptor than the one supplied with the scale. Verify that the AC power socket outlet is properly protected. Note: Please charge the battery before using the scale for the first time. - 6 - TBWS Washdown Bench Scales Technical Manual 4.

OPERATION Initial Start-up Warm-up time of 15 minutes stabilizes the measured values after switching on. 5.1. Basic Operation 1. Power On/Off: Turn on the balance by pressing on/off key. The display is switched on and the test is started and to turn off the scale, press the key again. 2. Zero Environmental conditions can lead to the balance exactly zero despite the platform not taking any strain. However, you can set the display of your balance to zero any time by pressing starts at zero. 3. Tare key, ensuring that the weighing The weight of any container can be tared by pressing button so that with subsequent weighing the net weight of the object being weighed is always displayed. Load weight on the platform. Press key. Zero is displayed, and tare is subtracted. Remove weight on the platform. Tared weight is displayed. It can set only one tare value. It will be shown with a minus value. Press to change between gross weight and net weight. To clear the tare value, remove the load and press displayed, tare weight is cleared. 4.
