5 3. Installation & Mounting Details 3.1 Installation Instructions before Install an Instrument: The instrument is powered from an external 24VDC source. The instrument can be operated from a computer; therefore, a clean power source is required for reliable operation. The incoming power should come from a source that is isolated from other process equipment. Cables carrying primary and switched power should be routed away from load cell and other signal cables to avoid electrical interference. Relays, motor starters and other inductive devices connected to the equipment must have reliable and effective arc suppression. Plastic insulating tape should not be used on load cell connections. Heavy electrical equipment should not be installed close to the weighing equipment. Excessive vibration will affect the accuracy of the weigh system and depending on the severity can cause damage to electrical and electronic components. The atmosphere should be dust free and not contain any corrosive gasses or materials, which could adversely affect the equipment. Check proper earthing of the unit. Check proper voltage supply and frequency of the electric supply. Check proper connection of load cell. 3.2 Mounting Install the instrument in a location where it will not be subjected to excessive heat, humidity or vibration. The unit should be installed at eye level so as to allow viewing be installed at eye level so as to allow viewing the display and access to the front panel keys. Avoid direct sunlight on the front of the instrument. Mount the instrument in the panel cutout of 96mm * 48mm. Fix the instrument with the panel using two nos. brackets provided with the instrument.

10 6. Menu List Functions Parameter in Weight Indicator SMIT 3015 is divided in three main Menus. Display DISP Menu Operation OPER Menu Calibration CAL Menu 6.1 Display DISP Menu Display Values DP (Decimal) 0, 0.0, 0.00, SVD (Step Width) 0, 0.2, 0.5, 1, 2, 5 ROUND (Rounding) 1, 2, 5

11 Decimal Position: DP Press Index key, to see DISP Menu after that press Right arrow key to see current selected DP decimal position. Press Right key to enter DP Menu after that use Up arrow' key to select desired decimal point position like for 0, 0.0, 0.00 and and select any one and press 'ENTER' key to store it in NVRAM. The decimal point will be displayed at newly selected position. Step width: Svd Use of Step width: Step width is the minimum change in weight required to display the weight. Display weight will only update when amount of change in weight is greater than or equal to value of Step width. Setting Svd = 0 will update Display weight directly. For example, if Svd = 2 is set and display weight is 15.0 kg now display weight will only update when consecutive weight is more than or equal to 15.2 because difference should be more than value set in Svd. Press Index key, you will see DISP Menu after pressing Right arrow key to display currently selected Svd.
