1 Introduction

This manual covers two models. PD12 IHS (high speed). This model fills one bottle at a time.
In the double head the tubes are mounted in pairs of 2 and via y-connectors these are joined into one tube in order to fill one bottle at a time.
and PD12 IDH (double head). This model fills two bottles simoultaneously.
In the double head the tubes are mounted in pairs of 2 and via y-connectors each set of tubes are joined into one tube in order to fill two bottles simoultaneously.
In general all sections of the manual cover both models; unless clearly specified.

1.1 The peristaltic principle

PD12 operates with a peristaltic dispenser head (tube pump), where the liquid only comes into contact with the flexible tube, the tube connections and the filling nozzle. The tubes are usually made of silicone, but other materials can also be used.
The dispenser head is designed in such a way that sterilized tubes can be mounted in the head without affecting the sterility.
The dispenser head is self-priming, and the dispenser head itself can stand to be run dry (not recommended for the sake of the tubes).
The dispenser head on PD12 works with four parallell tubes which are squeezed by rollers mounted on ball bearings. The rollers in are offset in order to eliminate pulsation.

1.4 Caution and employee safety

This manual should be read before using the PD12. It is strongly advised that
- Any kind of maintenance or cleaning of the machine not is carried out while power is connected
- Unauthorised / non-trained personnel should not open the cover of the electrical parts
- The machine is placed in such a way that it is not exposed to high humidity, high temperatures or other abnormal operating environment.
- The machine is not to be used in explosion hazardous environments.
- When operating the machine make sure that the dispenser heads are closed and that safety cover is placed above.
- The machine should be used for dosing and filling of liquid fluids, only.
A peristaltic dispenser head is not suitable for viscous products; see section 4.3

1.5 Essential training before daily use

Read the section with Daily Use, thoroughly before using the machine. Protective equipment and protective devices are installed:
The machine is equipped with a safety cover which protects the operator from hazards; the
machine will not run unless the safety cover is placed.
Always respect the symbols on the machine.
Cleaning must be performed as described in section 6.

3 Installation

PD12 must be placed on a stable bedplate. All electrical connections are on its rear.

Fig. 4 - Connections
The cable with plug (1) is connected to an earthed switch. The communication cable from MC12 (type 3) comes fitted with two 4-pin DIN plugs. One is
connected to the "net 1" socket (2) on the PD12, and the other plug is connected to the "net" socket on MC12. The terminator supplied with MC12 (4-pin blind DIN plug) is connected to the "net 2" (3) socket on PD12.
Should the system be operating more than one PD12, the "net 2" socket (3) is to be connected to the "net 1" socket (2) on the next PD12 by a communication cable (type 3). The terminator is connected to the last PD12 on the line.
PD12 is now ready to be switched on and to be programmed from the MC12. If the PD12 is one of several filling stations in a system, none of the stations may have the same
address and it must therefore be changed.
