Transport The PP40 (360 kg) is to be lifted and transported only be the transport screws TS supplied with the machine. (Fig.
Temperature variations If temperature variations are high (e.g. during air transport) the PP40 must be protected against condensed water. Otherwise the electronic components can become damaged. Intermediate storage Ensure that the PP40 is also stored dry during intermediate storage. Erection F Erect the PP40 on a firm base. Further parameters are given in the section „Technical data”. Net weight of PP40: approx. 360 kg The machine must be locked in position before starting up.
Important instructions for electrical connection 1. Electrical connection without a protective conductor PE is not permissible. 2. The drive of your PP40 is fitted with a frequency converter. To fulfill the EMC directive this is fitted with a line filter and shielded cables to the motor.
Operation Connecting the power supply H Au Ensure that the voltage and frequency of your mains supply correspond to the values on the type plate of the PP40. The mains supply must be fused up to at least 16A. (Fig. 4 Receiving socket and main switch) Plug the mains cable into the receiving socket Au on the rear side of the equipment. Plug the mains plug into the mains socket. Switch on the main switch H. Fig.
Emergency unlocking A key for the machine is included in the delivery, with which the PP40 can be manually opened if there is a power failure. (Fig. 7 Emergency unlocking) Remove cap K (I) Insert the (S) key into the (Ö) opening on the right-hand side. (II) To unlock the gear, the key must be pushed in further with some degree of force. While pushing the key in, turn it in a clockwise direction as far as it will go. A The cover can now be opened. b b . Fig. 7 Emergency unlocking Abb.
Insertion of pellet press rings and aluminum cups of the PP40 T The press ring P or the aluminum cup will be placed into the press tool by hand in the front position of the tool slide and will be filled with sample material. (Filling funnel T to be used) The filling quantity ranges from 8 to 12 ml, depending on the material. During sample preparation, the material to be pressed can be mixed with a standard binder.
Preparation of the pressing process Place the tool slide into the filling or cleaning position. Place the press ring into the die of the press tool. Fill in the sample material by means of the filling funnel. Pay attention that no material is laying on the ring rim. Remains on the ring rim can be removed by means of a brush. Put aside the filling funnel and push the tool slide into the pressing position slowly and steadily. The slide locks into place. You can then close the hood and start the PP40.
By pressing the START key the pellet is pressed out of the pressing tool and can be removed. The display shows “START = Continue”. Clean the pressing tool (please refer to the following chapter “Manual cleaning of the pressing tool”). After cleaning the pressing tool, the pressing stamp is moved to the filling position by pressing the START key. Manual cleaning of the pressing tool After having removed the pellet, material residues must be removed manually from the pressing tool.
