2. Use
When filling foaming products in larger volumes, it is often needed to move the filling nozzle to the
bottom of the bottle and raise the nozzle at the same speed as the product level rises in the bottle
during the fill. The EBU250 is used for these applications and is therefore mainly used together with
Flexicon fillers PD22I and GD30I.
The EBU250 system uses a long filling nozzle with outside valve. The nozzle is carried by two
moveable rods, which are driven by a stepper motor.
The nozzle will normally be the pneumatic type with outside valve to prevent dripping during nozzle
movement. The stroke length of the EBU250 system is adjustable and is maximum 250 mm.
The bottle is placed against the bottle support and on the platform at the front of the unit for correct
height and centre positioning.
The EBU250 unit is connected to the main supply and to an MC12 control computer.
There are three action sequences in a complete cycle:
Transport
- From the top position to bottom of the bottle.
Filling - Nozzle raises at the speed of the filling.
Transport - From the position where the fill ended and to the top position.
All three actions are programmed at the MC12 control computer in function 51. The parameters will
be saved with the filling program.
Both transport and filling speeds can be adjusted from 1 to 250 mm per second.
EBU is manufactured from AISI304 steel, Delrin and anodised Aluminium.
3. Filling Nozzle
For the EBU 250 is a pneumatically solution recommended, but for the EBU described in this manual
the nozzles are customised.
4. Connections
Electrical connections are placed on side and rear of EBU.
EBU must be supplied by 230 VAC with ground. The supply is connected to (1) in Fig. 4.1
EBU cannot perform filling by itself hence it must be connected to a controller like Flexicon’s MC12
which the standard Master Controller for Flexicon machines.
If using the configuration as shown below, the communication cable from MC12 is connected to the
"A" socket “Net 1” on the drive. Then the multi cable is connected to the MC12 and the other end is
connected to the EBU. EBU should be connected to 230 VAC with earth.
The MC12 is programmed for use with EBU by using function 51 and answering the question, which
appear on the MC12 display. For more information on programming please see later in this manual or
refer to reference manual for MC12.
