6 3 Descripion of he cenrifuge The EBA 20 / EBA 20 C is a microprocessor-conrolled cenrifuge which is comprised of he following elecrical componens: Conrol panel Power board Moor wih speed sensor (speedomeer) Lid lock sysem Imbalance swich (only wih EBA 20 C) All elecronic componens are on mains, due o he DC-coupling Seuereil LED / Conrol panel LED Schniselle / Inerface EEPROM Nez / Mains Verschluß / Lid lock Deckelschaler Lid swich Unwuch Imbalance Drehzahlsensor (Tacho) speed sensor (speedomeer) Leisungseil Power board mi Mikroprozessorseuerung und Mooranseuerung wih microprocessor conrol and moor conrol Moor 6/31

7 3.1 Conrol panel A3 The conrol panel have only resriced conrol asks, i disposes of he following characerisics: Inpu panel for operaion parameers Indicaion elemens Transmission of he signals o he power board via he inerface. Soring of cenrifuge version Soring he machine version and he brake seing. By means of he machine version he power board is informed which kind of cenrifuge has o be conrolled. Then he power board akes he corresponding values from he ROM. e.g. Max. Speed Acceleraion and deceleraion ramps Communicaion wih he power board via TTL inerface. The power supply for he conrol panel is ransmied via he fla ribbon cable: Pin 1 GND Pin 4 +5V 3.2 Power board A1 The power board is an combinaion of: Conrol panel Volage supply Moor-conrol The power board carries ou he following asks: Power supply 15 V, DC for imbalance swich Power supply 5 V, DC for conrol panel and speed sensor Plugging saion of he moor Conrol of he moor wih riac phase-angle conrol Monioring of he moor curren. Braking of he moor wih brake resisor Plugging saion of he imbalance swich (only wih EBA 20 C) Evaluaion of he imbalance swich (only wih EBA 20 C) Plugging saion of he lid lock Conrol of he lid lock magne a sand sill of he roor. Evaluaion of he lid lock signal (lid open or closed). Communicaion wih he conrol panel via TTL inerface evaluaion. 3.3 Moor M1 The moor is conneced via a plug o he power board. The moor is a collecor-moor wih carbon brushes. The moor is conrolled by he power board. 7/31

8 3.4 Lid lock Y1 Opening of he lid lock is prevened by a lach. The lid lock can only be opened when he relay REL 602 on he power board is energised. This occurs when he roor is a sandsill, mains power is applied and he key is pressed. The solenoid is energized for hree seconds and releases he lach. The cenrifuge can only be sared when he lid is closed. A microswich on he lid lock deecs he posiion of he lid lock (open/closed) and repor i o he power board. 3.5 Imbalance swich S2 (only wih EBA 20 C) A microswich (break conac) deecs any imbalance. Imbalance can only be deeced in running mode (saring, cenrifuging and braking). If any imbalance is deeced, he drive is changed over o braking. 4 Troubleshooing procedures Fuses in insallaion in which cenrifuge is insalled are inac. Mains inpu fuses of cenrifuge are inac.
