3.0 INSTALLATION 3.1 3.2 LOCATING THE SCALES • The scales should not be placed in a location that will reduce the accuracy. • Avoid extremes of temperature. Do not place in direct sunlight or near air conditioning vents. • Avoid unsuitable tables. The table or floor must be rigid and not vibrate. • Avoid unstable power sources. Do not use near large users of electricity such as welding equipment or large motors. • Do not place near vibrating machinery.
3.3 • SETTING UP THE SCALES Attach the power supply module to the connector on the side of the indicator. Press the [On/Off] key. The software revision number will be displayed followed by a self-test showing all digits before the zero is displayed along with the unit of weight that was selected last. 3.4 CONNECTIONS 3.4.
3.4.2 CONNECTION OF RS-232 RS-232 serial interface is a plug as figure 2 shows: 2 1 3 4 1: Pin GND, Signal Ground 2: Pin RXD, Received Data 3: Pin TXD, Transmitted Data As viewed from the back of the indicator See section 9 for details of the RS-232 Interface. 3.4.3 CONNECTION OF RELAY DRIVERS The output to drive external relays is on the circuit board inside the enclosure. To gain access you must remove the 6 screws securing the front to the rear of the case.
4.0 KEY DESCRIPTIONS [>Z/T<] If near zero, Sets the zero point for all subsequent weighing. The display shows zero. Tares the scale. Stores the weight currently on the scale as tare value, subtracts the tare value from the gross weight and shows the results A secondary function, is of “Enter” key used when setting up the value for the Parameters. [Pcs/ ] Selects parts counting. Used to set the sample quantities while parts counting.
[Func/C] Selects the Functions of the scale. If the scale is weighing, it will select parts counting. If it is not in weighing mode, it will return the user to weighing. A secondary function (C) is to act as a clear key when setting values for Parameters. [Print/M+/Esc] Sends the results to a PC or a Printer using the RS-232 interface. It also adds the value to the accumulation memory if the accumulation function is not automatic.
6.0 OPERATION 6.1 ZEROING THE DISPLAY • You can press the [Z/T] key at any time to set the zero point. This will usually be necessary when the platform is empty. When the zero point is obtained the display will show an indicator for zero. • The scale has an automatic re-zeroing function to account for minor drifting or accumulation of material on the platform. However you may need to press the [Z/T] key to rezero the scale if small amounts of weight are shown when the platform is empty. 6.
• Press the [Z/T] key to tare the scale. The weight that was displayed is stored as the tare value and that value is subtracted from the display, leaving zero on the display. The “NET indicator will be ON. As a product is added only the net weight of the product will be shown. The scale could be tared a second time if another type of product was to be added to the first one. Again only the weight that is added after taring will be displayed. • When the container is removed a negative value will be shown.
6.4 PARTS COUNTING If parts counting is enabled, See section 7.4, it is possible to count parts using a sample of the parts to determine average piece weight. • Before starting, tare the weight of any container that may be used, leaving the empty container on the scale. Place a known number of samples in the container, if used. The number should match the options for parts counting, i.e., 10, 20, 50, 100 or 200 pieces.
• Press the [Pcs/ ] key to return to normal weighing. Press the [Pcs/ ] key again to start counting a different sample. 6.5 CHECK-WEIGHING Check-weighing is a procedure to cause lamps to come on (and if enabled, an alarm to sound) when the weight on the scale meets or exceeds values stored in memory. The memory holds the last values for a high and a low limit when the power is turned off. The user can set either one limit or both as described below. See Section 7.
BOTH LIMITS SET The display will show OK F3 bEP = bP InL . when the weight is The beeper will sound between the limits when the weight is between the limits, i.e. OK F3 bEP = bP OtL Beeper will sound if weight is outside the limits. LOW LIMIT SET The display will show LOW HIGH LIMIT is set to when the weight is less zero than the Low Limit. Above the Low Limit the display will show OK, F3 bEP = bP InL . The beeper will be off when the weight is less than the Low Limit.
NOTE: Weight must be more than 20 scale divisions for check weighing to operate. Below 20 scale divisions the LED’s will not light and the beeper will not be on. The Check-weighing function can be set up during Weighing or Parts Counting by entering values as Low or/and High Limits keyed in by the user. The limits are displayed in kg (or Lb) or pcs respectively.
6.6 ACCUMULATED TOTAL • The scale can be set to accumulate manually by pressing the [Print/M+/Esc] key or automatically when a weight is removed from the scale. See the Section 7.3 for details of setting the Parameter “C3 PRM” and “C4 Aon”. The accumulation function is available when weighing or when counting parts. However the memory is cleared if the weighing units or functions are changed.
6.7 PERCENT WEIGHING The scale can be set to perform percent weighing. See Section 7.2. The scale will use a mass on the platform as the 100% reference weight. If the platform is empty (or the scale is tared) then the user can input a reference weight using the keypad. • Press [Func/C]. The first option is “FunC 1”, press the [Func/C] key again display “FunC 2”. • Press the [Z/T] key. “P1 PCt” will be displayed. • Press [Z/T] again to enter percent weighing.
• The number of decimal points will depend on the weight used in comparison to the capacity of the system. A smaller weight will show only “100%” while a larger weight might show “100.00%”. • If the scale was showing zero weight when entering this function, then the user must manually enter the weight to be set as 100% as described below. • Press the [Z/T] key. “P1 PCt” will be displayed. • Press [Z/T] again to enter percent weighing.
6.8 ANIMAL (DYNAMIC) WEIGHING The scale can be set to animal (dynamic) weighing for weighing any items that are unstable or may move. See Section 7.4. The scale will use a special filter to minimise the effects of any movement while the moving animal or unstable samples are on the scale. • Press [Func/C]. The first option is “FunC 1”, press the [Func/C] key again to display “Func 2”. • Press the [Z/T] key. “F2 PCt” will be displayed.
6.8.1 ANIMAL WEIGHING PROCEDURE • With the platform empty the display will show zero weight. Place containers or blankets onto the platform and press the [Z/T] key to zero the display. The scale may go into the animal (dynamic) weighing procedure when the items are placed on the scale but will return to showing zero when the [Z/T] key is pressed. • Place the animal or sample to be weighed on the platform. • The display will show the Animal/Dynamic weighing symbol until a stable weight is determined.
7.0 USER PARAMETERS Pressing the [Func/C] key during normal operation allows the user to access the parameters for customizing the scale. The parameters are split into 4 groups1. Check weighing parameters, 2. Percent and Animal Weighing Functions 3. RS-232 parameters and 4.
