5. Reversing (back suction)
Value: An integral number
Range: 0 - 10
If the reversion is changed, a recalibration should be made.
6. Batch size
Value: Number.
Enter the number of fills you want the filler to perform when started by <GO>, foot switch or via
electrical signal. Any number of fills between 1 and 65,000 can be selected.
When the filler is operating in automatic system, where the system itself starts the filler each time
a bottle is in position, THE VALUE IN THIS FUNCTION MUST ALWAYS BE 1.
7. Delay (Timer 1)
Value: Seconds.
If more than one fill is chosen in function 6, enter the required delay between the fills.
The value of the delay can range between 0.1 - 25.0 seconds, with a graduation of 0.1 second.
8. Completed fills
Value: Number.
Nothing can be entered in this function since it only displays the number of fills completed since
the latest reset of the function.
To reset this function, press the <C> key.
9. Specific gravity
Value: Decimal number.
Enter the specific gravity of the liquid in g/ml if the required volume was entered in Function 1 and
if this volume is controlled by balance. A re-calibration is necessary after entering the specific
gravity.
10. Output rate
Value: Number of fills per time unit.
Nothing can be entered in this function as it only displays the current output.
The function displays how many fills the system carries out per time unit. The time unit can be
HOUR or MINUT.
The function operates as follows:
The PF22 records the precise time between two fills via the built-in clock, and calculates the
number of fillings per time unit.
The display is updated at the completion of each fill.
The function can be called up for viewing, but it cannot be reset and values cannot be entered in
this function.
15. Input mode
Value: 1 or 2.
1 =
The foot switch will only function as a starter.
2 = First press on the foot switch starts the filler.
Second press on the foot switch stops the filler.
Third press on the foot switch starts the filler.
