Commissioning - Priva Compass Installation Manual

Commissioning

Commissioning for the first time
1. Check that the unit is working (see
2. Enter the data for the load cells (see
engineer only) (page
3. Follow the calibration procedure, see
108).
Checking operation of the weighing indicator
Check the status of the LEDs in the housing. The three green LEDs with the text V24ac, Vcc and V18+
must light up brightly. The yellow LED with the text T1 must flash after the weighing indicator has
started up. Go to the chapter "Fault diagnosis" if the weighing indicator does not work after it has
been connected.
Setting the load cell data (to be performed by the service engineer only)
When the slab weigher is taken into use, the specific data for the load cells in the weighing platforms
must be entered in the weighing indicator. You can do this in the Load cells menu. The numbers for
Sensitivity and Zero point appear on the cables in the weighing indicator.
1. Open the weighing indicator and let the cover with the display hang down.
2. Go to the menu Load Cells .
3. Deactivate the menu protection by pressing "Enter" followed by " ↑ " and hold this key combination
down for 3 seconds. <<MENU>> will change to >>MENU<<.
4. Activate the menu by pressing "Enter". The display will show Sensitivity 1 .
5. Press "Enter" to enter the sensitivity of load cell 1.
6. Enter the sensitivity by using the arrow keys. This figure can be found on the weighing platform
cable. The value of the setting changes more quickly if either of the arrow keys is pressed down
continuously.
7. Press "Enter" to confirm the value you just set.
8. Press " ↓ ".
9. The display will now show Zero 1 ; press "Enter" if this is to be adjusted.
10. Enter the zero by using the arrow keys. This figure can be found on the weighing platform cable.
11. Press " ↓ " and enter the sensitivity for load cell 2 and the zero for load cell 2.
12. Then enter the zero for load cell 2. Enter the data for load cells 3 and 4, if present.
13. After pressing " ↓ " following the entry of Zero 4 for load cell 4, the display will show # of Load
Cells .
14. Press "Enter"; this enables you to enter the number of load cells.
15. Enter the number of load cells (2 or 2) using the arrow keys and press "Enter" to confirm if this
value differs from the default value (which is set to 4).
16. Press " ↓ ": the display will now show #kg/Load Cell .
17. Press "Enter" if the weight range of the load cells is to be changed.
18. Press " ↓ ". The display will now show Set tare Weight ; here the new zero weight should be
recorded. The display shows the current nett weight surrounded by << >> brackets. Pressing
"Enter" will change the brackets so they are turned inwards, i.e. >> <<. Press "Enter" again in
order to record the new zero weight. The display will now show <<000,000>>. Press "Esc" if the
current nett weight is not to be adjusted. The same can be done with the menu Slab calibration
(please refer to the chapter "Operation and display"). This function can be used to check the
weighing unit using a small calibration weight (1 kg). Perform the Set tare Weight function and
place the calibration weight on the unit. Check the display to see if the correct weight is shown,
while keeping in mind the measuring accuracy of the weighing unit as a whole.
19. Press " ↓ " if you wish to rectify small deviations caused by installing the weighing unit. However,
it is not mandatory to perform this function.
20. The display will show Adjust Sens. It is assumed that the weighing unit has been tared. Place a
20 kg calibration weight at the height of each of the weighing platforms. The left of the display
will show the nett weight. If this is incorrect it can be adjusted by pressing "Enter" and using the
arrow keys until the actual nett weight on the left of the display shows a value which equals the
total weight of all calibration weights. Press "Enter" to confirm.
21. Press "Esc" to leave the menu and reactivate the menu protection.
