RECOMMENDATIONS FOR CORRECT INSTALLATION OF WEIGHT INDICATORS

- The entry into the cable board of cells must be independent ( on one side or the other of the

board ) and directly connected to the terminal board of the device without breaking by bearing terminal boards or passing through troughs containing other cables.

- Use the " RC " filters on the instrument-driven coils of the remote control switches. - Avoid inverter, if inevitable, use filters and separate with sheets. - The installer of the board is responsible for securing the electrical safety of the indicators. - It is a good norm to let the indicators always switch on to prevent the formation of condensation.

OPERATION By closing the start contact or by pressing the DOSA key the instrument starts the batching and verifies that the weight is lower than the minimum weight programmed, it executes the auto-tare ( if it is enabled ) then closes the set and preset contacts. When the weight has reached the preset value the related contact will be opened, once it has reached the set value less the fall value the set contact will be opened and after the pause time is over (999,9 sec.) memorizes the consumption and closes the cycle end. When the weight has reached the minimum weight (unloading phase) and after the safe emptying time is over (999,9 sec.) the instrument will open the cycle end contact. If more than one cycle has been programmed, the instrument will automatically carry on. STARTING UP THE INSTRUMENT Switch on the instrument and wait about 5 minutes for all the components to reach a steady temperature. Check that the displayed weight is positive and that it increases when a weight force is applied to the container. If a negative value is displayed, check the load cell connections and ensure that the cells are correctly positioned (mounting direction). Also check that the container is correctly installed (tube position, sleeves, mounting accessories, etc.).

TARE ZERO-SETTING: Make sure that the container is empty, then press and the display will show tArA. Hold down the key and at the same time press ENTER to set the tare to zero.

INSTRUMENT THAT HAS ALREADY BEEN CALIBRATED

Laboratory setting: CELL ( ); nU-U ( ); rISO ( ) In this case the instrument has already been calibrated, proceed to Instrument calibration check.

INSTRUMENT CALIBRATION CHECK:

Make sure that the container is empty and that the instrument displays zero. Place a significant quantity of product in the container (at least 50% of the maximum quantity of product that is to be weighed but in any case less than 9,999) and make sure that the instrument displays the correct value. - If the displayed value is different from the weight known to be in the container ( bigger than 1-

2% ), make sure that this is not due to mechanical causes and again check the electrical connections and the direction in which the load cells are mounted.

- If the difference in weight is negligible (about 1-2%), then proceed to Correcting displayed weight from keyboard.

CORRECTING DISPLAYED WEIGHT FROM KEYBOARD:

Procedure subject to entry of access password ( see item PASS on page 19).

When the weight is displayed, press . The display will show CAL l. Hold down the key

time one wants to re-execute the formula ( from 1 to 9999 ) by using the and the keys, then press ENTER. The instrument verifies the following conditions : - the formula must be programmed, otherwise the F._ _ _ blinking message will appear, press DOSA to exit ; - only if the auto-tare is enabled : the container must be " in tare " ( the weight present into the container must be lower than the minimum weight programmed, otherwise the tArA blinking message will appear. Press DOSA to exit ). Once all the conditions are met, the instrument starts the batching: if the auto-tare is enabled, at the beginning of the batching the system waits for about 2 seconds before executing the auto-tare , the SET and PRESET contacts will be closed contemporarly. Once the PRESET value has been reached the instrument opens the PRESET contact and if the LE.on and LE.oF values are programmed the "tapping" phase will start ( the SET contact will be opened and closed with the LE.on and LE.oF times ). Once the value programmed less the fall value has been reached, the instrument opens the SET contact and closes the cycle-end contact, it will be re-opened at the reaching of the minimum weight and after the safe emptying time is over. If the automatic fall or the consumption are enabled, after the SET opening, the system waits the pause time and then closes the cycle-end. Automatic fall: The system calculates the automatic fall every 1 - 99 batchings, until the weight batching will be included into the limit programmed at the voice div in the Secret Parameters. If a tolerance value different from zero has been programmed in the parameters and the difference between the SET value programmed and the reached weight is higher than the tolerance value, the SCRAP contact will be closed for 3 seconds. If the printer is enabled the batching data will be printed reporting date and time of the batching. Now if more than one batching cycle has been programmed, the instrument will carry on in automatic.
