7. F ILLING WITH FT-13
7.1 Overview
FT-13 has 9 standard filling programmes for common filling applications as indicated below.
Programme Description Typical Application
0 Filling above the open container Liquid or bulk filling into container
1 Filling below the bunghole of the container Above level liquid filling
2 Below surface filling in the container Liquid filling for foaming products
3 Filling and emptying Type 1 Automatic bag filling machines
4 Accurate filling and accurate discharging Filling in or discharging from tank/hopper
5 Charging and accurate discharging Sticky/high viscosity materials filling
6 Filling and Emptying Type 2 Automatic bag filling machines with total check
7 Filling the bag Filling by weighing the bag
8 Bag filling from hopper scale Filling machines with hopper and bag catcher
7.2 Commissioning
To start up the filling system, please follow these steps:
1.
Select your filling programme
2. Prepare the digital I/O connections according to the selected filling programme (see chapter 4.2.3)
3. Set up and calibrate the scale (see chapter 6)
4. Enter the process parameters for the selected filling programme as explained in chapter 7.3 and 7.6
5. a. If you don‟t use recipes: Enter Target, tolerance and preset values as explained in chapter 7.4
b. If you use recipes: Enter the recipes as explained in chapter 7.5
6. Perform tests and optimise the filling process
You can find the meaning of the filling parameters in the filling cycle diagram shown below (Fig. 7.1). In this
diagram the instrument does not follow the weight during coarse and fine feeding control delay periods. This
increases the reliability of the system. The actual weight value is read out at the end of the settling time. This
allows for better tolerance control and / or cut-off point adjustment.
Figure 7.1 Typical filling cycle diagram (displayed weight vs time)
You can change the target and preset values very quickly via keys. If you use the recipe memory, you can
select the recipe (set of target, preact, dribble, tolerance, coarse, middle, fine) to spare time for different filling
applications.
