3 GENERAL INFORMATION
3.1 Unpacking and inspection
GD30I is a dispenser in the Flexicon Multi Filling System (FMFS). The GD30I cannot do fillings by
itself, but must be connected to Flexicon's control unit, MC12, or to a PC with RS485 multidrop
communication.
Please check that all ordered items have been received and that no items were damaged during
transport. In case of any defects or omissions, please contact Flexicon A/S or your supplier
immediately.
When ordering spare parts or accessories for the GD30I, please state the serial number stamped.
The serial number is stamped on the label on the bottom of the GD30I.
Please check that the connected mains plug is of the correct type with the correct earthed switch.
If this is not the case, the correct type of plug must be mounted with the following connections.
Yellow/green -
earth
Blue - neutral
Brown - phase
ALWAYS REMEMBER that this machine must be earthed.
3.2 The Dispensing Principle
GD30I operates with a pump of positive displacement rotary type. The volume at the inlet
increases when the gears rotate and the product ids drawn into the pump. It is then transported in
the space between the gears and the periphery of the body to the discharge side. The volume
between the gears is reduced here and the product is forced out through the outlet.
The gears operate without metallic contact with casing. The pumps have gears in AISI 316 acid
resistant steel (PTFE impregnated). This gives an efficient performance and gentle handling of
liquids products.
The gaskets are made of EPDM.
THE PUMP MUST NOT RUN DRY.
The best performance is reached with a positive product support.
The pump needs a filling nozzle with cut off valve.
