Enter a 0 on the numeric keypad and press If Tare indicator is lit, the tare will need to be cleared. Press CLEAR TARE CODE Gross weight, Zero, and Stable indicators should be lit. Place item(s) to be weighed on the platform. Read the gross weight in the weight display. 12

13 WEIGHING WITH TARE A tare weight may be entered into the 40SS by one of two methods. They are Platform Tare and Keypad Tare. With Platform Tare, the tare weight is entered by placing a container onto the platform and pressing the tare button. With Keypad Tare, the tare weight is entered through the numeric keypad and does not require the use of actual weight. In addition the 40SS has a preset tare feature, where tare values may be stored under Tare Identifier code numbers. The stored tare value may then be called up by simply entering the identifier code numbers. WEIGHING WITH PLATFORM TARE Remove all weight from the platform. Enter a 0 on the numeric keypad and press Place an empty container, or a weight value equal to the desired tare weight onto the platform. Wait for stable indicator to come on. Press TARE The weight display will go to zero, the Gross weight indicator will go off and both the Net and Tare weight indicators will come on. The message display will show the current tare weight The 40SS is now ready to read the net weight. Place items to be weighed into the container. WEIGHING WITH KEYPAD TARE CODE You may begin with weight on or off of the platform. Be sure the Tare Indicator is not lit, if so: CLEAR Press to clear out the previous tare value. TARE Enter a new tare value via the numeric keypad. As the numbers are entered they will be displayed in the message display. If a mistake is made while keying in the value, use the CL button to clear the mistake and begin again. With the correct tare value showing in the message display, press TARE The Gross weight indicator will go out, and the Net, Tare, and Preset Tare indicators will come on. The message display will show the current tare weight. If there is no weight on the platform, the weight display will show the tare value as a negative number. If there is weight sitting on the platform, the tare value will be subtracted form the weight being displayed. The 40SS is now ready to read the net weight. 13

14 STORING PRESET TARES Enter a tare weight into the 40SS by one of the methods described above. This tare value may now be stored for later use under a tare identifier number. Use the numeric keypad to enter the desired tare ID from 1-9. This ID may be either numeric or alpha characters, or both. The characters keyed in will show in the message display. With the desire ID showing (0 9) in the message display, press The message display will show <TM: XX> (where XXXX represents the entered ID number) and the Net and Preset Tare indicators will be lit. To exit the Preset Tare mode: Press The Preset Tare will remain stored in the 40SS memory, but the indicator will return to the Gross weight mode. The stored tare may be recalled at any time by keying in the ID number and pressing STORING TARES IN THE 40SS DATABASE Enter a tare weight into the 40SS by one of the methods described above.

16 COUNTING MODE COUNTING WITH A SCALE A counting scale is able to count parts based on the weight of one piece (piece weight). When a container is placed on the platform, the scale reads the total net weight and then divides that value by the piece weight, the result is then displayed as the count. While counting parts by weight is one of the fastest and most convenient methods available, it must be understood the there will always be some errors in the count. There are a number of factors involved that add to these errors. 1. Piece weight errors - No two parts will ever weigh exactly the same. The way to help overcome piece weight errors is to set up the count by placing a sample onto the platform and allowing the 40SS to calculate the piece weight. This calculation is know as the Average Piece Weight (APW) because the scale looks at the total weight of the sample and divides it by the number of parts in the sample, the result is not the exact weight of one part but an average of all the parts. In addition, the larger the sample used, the better the average piece weight that can be calculated. 2. Errors in the container weight - If a keypad tare is used for a container and the weight of the container is slightly different then the value keyed in, the error in the weight could adversely affect the count of smaller parts. The best way to overcome this error is to place the empty container onto the platform and tare it off, then placing the parts to be counted into the container. 3. Inherent errors in the scale - This type of error will be most noticeable when extremely small parts are counted on a scale of too large a capacity. It is important that the capacity of a counting scale be correctly chosen for the type and size of parts that are to be counted on it. The best way to reduce the scale errors would be to correctly choose the capacity of the scale and to use as large a sample as possible. (The larger the total weight of the sample, the more accurately the scale can calculate the average piece weight.) There are two ways of entering piece weights into the 40SS, by entering the piece weight through the keypad or by placing a sample of parts on the platform. KEYPAD ENTRY OF PIECE WEIGHT Use the numeric keypad to key in the weight of a single piece. The numbers will be displayed on the message display as they are entered. Press and hold and then press SHIFT APW The 40SS will return to the count mode, the piece count indicator will be lit and the weight display will show the count. The piece weight is now stored until a new piece weight is entered. The 40SS weight display may now by switched between displaying the count, the piece weight, or the weight. Press UNITS Each time this is done the 40SS will cycle through the count, weight, and piece weight. TARE A container may be torn off by placing it on the platform and pressing A keypad tare may be entered as long as the weight display is displaying the weight. 16

17 ENTRY OF PIECE WEIGHT BY SAMPLE Be sure there is nothing on the platform and all tares have been cleared. If a container is to be used to hold the parts being counted, place it on the platform. Press Count out a sample of the parts to be counted and place them on the platform. Key in the number of parts in the sample, using the numeric keypad, the numbers will be displayed on the message display as they are keyed in. Press The average piece weight will be displayed in the weight display for a few seconds. The weight display will then switch to displaying the count and the number of pieces in the sample will show on the display. Add the rest of the parts to be counted to the container. With the sample method of entering the piece weight the 40SS is able to count the parts a few at a time and update the average piece weight at the same time. This will increase the accuracy of the count, helping to eliminate some scale errors and differences in piece weight in the parts. Place a quantity of parts on top of the original sample. (Quantity should not be larger than 50% of the original sample.) Press The new average piece weight will be displayed for a few seconds and then the weight display will return to the count. Press TARE APW S APW S UNITS Each time this is done the 40SS will cycle through the count, weight, and piece weight. Once again a new container may be tared off by placing it on the platform and pressing A keypad tare may be entered while the weight display is displaying the weight. TARE 17

18 STORING PIECE WEIGHTS IN THE 40SS DATABASE Establish a piece weight into the 40SS by one of the methods described above.

19 CHECK WEIGHING / SETPOINT OPERATION The check weighing operation of the 40SS allows the operator to enter a target weight into the indicator s memory, along with under and over limit targets. Entering a target weight will initiate the bar graph display and the indicator may be programmed to beep intermittently whenever the weight on the platform is in the target range, between the over and under targets. In addition, if your indicator has the optional four relay Setpoint board installed, these setpoints will respond to the target weight and over/under limits based on the type of setpoint definition established in programming.

At this point you may press twice to exit the menu mode, or press to move to the next step. ESC >> When you press to select the User Mode, the 40SS will move to a step where you will define the condition that will cause each of the four relays to activate. The condition for each relay is defined separately and is dependent on nine scale conditions being in a certain state. The nine states used to determine the activation of a setpoint are: ZR - The zero indicator is on. NZ - The weight is non-zero. UN - The weight is in the Under condition. TG - The weight is in the Target range. OV - The weight is in the Over Condition. WS - The weight is less than Set point Zero. SW - The weight is greater than Set point Zero. NS - The weight is not stable. ST - The weight is stable. There are 14 different combinations of these scale conditions that may be used to determine when to activate each of the four setpoints. When you press to select the User Mode the message display will show the first combination of scale conditions and the weight display will show four zeroes. Each of the zeroes represent one of the setpoints. On the numeric keypad, the number 1 through number 4 keys are used to select or deselect each of the setpoints. When a setpoint is selected, a 1 will show in that position on the weight display and when it is deselected a 0 will show. Below is a list of the 14 combinations of scale conditions as they will appear in the message display: [ 1] ZR UN WS NS [ 2] ZR UN WS ST [ 3] NZ UN WS NS [ 4] NZ UN WS ST [ 5] NZ UN SW NS [ 6] NZ UN SW ST [ 7] NZ TG WS NS [ 8] NZ TG WS ST [ 9] NZ TG SW NS [10] NZ TG SW ST [11] NZ OV WS NS [12] NZ OV WS ST 30

39 PENNSYLVANIA SCALE Model 40SS Weigh and Count Indicator CALIBRATION MANUAL Pennsylvania Scale Co. 21 Graybill RD. Leola PA FAX:

40 INTRODUCTION The Pennsylvania Scale Model 40SS weight and count indicator may be calibrated entirely through the front panel keyboard. This means that in many instances the indicator housing will not have to be opened. Access to calibration is accomplished by entering a code number during the diagnostic count down. Your indicator was supplied with a list of access codes. If you need the code number to access the calibration, contact your Pennsylvania Scale distributor. (It should be noted that when the 40SS is being used in a legal for trade application, entry into the calibration will require that the scale system be re-inspected by your local weights and measures bureau.) 40

41 CALIBRATION ING CALIBRATION The 40SS indicator uses a front panel calibration method and does not require that the indicator be opened up in order to calibrate. To enter calibration: Press ON to turn the indicator on. OFF Wait for the indicator to begin the diagnostic countdown, beginning with all zeroes on both displays. During the diagnostic countdown, but before it is completed. SHIFT Press and hold and press. The weight display will show <0> and the message display will show < USER ID> Use the numeric keypad to key in the calibration entry code: Press The weight display will show the date the indicator was last calibrated and the message display will show the code of the last user to adjust the calibration and the number of times the indicator has been calibrated. Press ESC Weight display will show the current date and the message display will show <DATE>. Use the numeric keypad to adjust the date if necessary. ESC Press to continue. 41
