Section 7: Operations Section 7 Operations 7.1. BASIC SCALE OPERATIONS Upon power up the Indicator performs a warm-up cycle. The Indicator initiates a test, displaying numbers 1 to 8, and lights up all LED’s. The Program number and Revision Information displays. The Indicator then displays the current weight on the scale 7.2. KEYPAD FUNCTIONS, WEIGH MODE KEY ACTION Recipe 1-4 Enables or disables programmed recipe in Checkweigh mode.
Section 7: Operations 3. Place container/object on scale (Tare weight). 4. Press the tare key. 5. Place material in container or add objects (Net weight). 6. Read the net weight on the display. Gross/Tare/Net Weighing 1. Press the B/G / Net key, if required, to set display to GR (gross). 2. Press the Zero key, if required, to set scale to “0.” 3. Place container/object on scale (Tare weight). 4. Press the Tare key. 5. Place material in container or add objects (Net weight). 6.
Section 7: Operations Port 1 set to Auto and Aout set to no. 1. After weight is applied, and if the weight is greater than the accumulate threshold, the indicator will flash all the green ACCEPT LEDs for one second showing that the weight has been stored as an accumulation. 2. If a print is to occur, press print and port 1 will transmit the following: “Weight nn = wwwwww uu GR/NT” nn is the number of the current accumulated weight in numerical order. wwwwww is the last accumulated weight.
Section 7: Operations 2. Weight on the scale must now be removed to less than .5 grads before the next accumulation can occur. 3. Repeat steps 1-3 to continue accumulations (up to 99). Displaying Accumulated Weight and Count. 1. Press and release Over/Under/Next The indicator will alternately display the total accumulated weight and the number of accumulations for two seconds each. The count is left justified followed by Acc, and the total weight is right justified. 2.
Section 7: Operations 3. Press Program/Enter to display Hold X, where X is either Y or N. 4. Press Over/Under/Next to display Hold Y if necessary. o 5. Note: Peak Hold function must not be used with Checkweighing. Press Program/Enter to display CSaved, and returns to weigh mode. Indicator is now in Peak Hold mode. To operate peak hold: 1. Press the 1 button to activate Peak Hold mode. The first three indicators for UNDER, ACCEPT and OVER will flash indicating Peak Hold is active.
Section 7: Operations 10. With the desired selection displayed, press Program/Enter to display units. With units displayed, one of the units legends will be lit. This is the weigh units the Checkweigh limits will be defined by in the following steps. 11. Press Over/Under/Next to scroll through the choices, including custom units. 12. With the desired units legend lit, press Program/Enter to display hand y, or hAnd n. This determines the method for defining the acceptance band.
Section 7: Operations 23. The entire under bar graph, the entire accept, and the first segment of the over bar graph will be illuminated. A previously programmed weight value is displayed with the leftmost digit flashing. This is the end of accept point. If required using the same procedure as identified in step 21 above, enter the correct value for the end of the accept range. When the correct end of accept value is displayed, press program/enter. 24.
Section 8: Service and Maintenance Section 8 Service & Maintenance 8.1. EXPANDED DISPLAY MODE The Enviro™ Series can be placed in expanded resolution mode to assist in troubleshooting and maintenance. Simply press S2 on the main PCB and the display indicator will immediately display the weight in 10X resolution.
