Acceleration/Deceleration Start/Stop To start, shut lid and press Start. Centrifuge will run to set time and then automatically brake to STOP. Press STOP if you need to stop before timer ends To Increment Accel Rate: Hold down Function and press Speed Up (see Accel LED on speed display) To Increment Decel Rate: Hold down Function and press Speed Down (see Decel LED on speed display) To Increment Memory No’s: Hold down Function and press Pulse (see memory LED on speed display) For Rcf/Rpm mode: Hold down Function and press Lid Open (see correct dot on speed display) Function Scientific Centurion Time Pulse (secs) Hold down Pulse to run centrifuge. Time (in seconds) counted up from zero on time display. Release button when desired time is reached. Memory 2000 and K MODELS OPERATING MANUAL This will recall the required program. While still holding Function, press Recall. Hold down Function and press Memory until no. 6 shows in display. To Recall a Program: e.g from memory number 6 This will save the information to the required number. While still holding Function, press Store. Select Speed and Time parameters. Hold down Function and press Memory until no. 6 shows in display. To Set a Program: e.g in memory number 6 Programs 39 WAIt You have tried to open the lid. Please wait for 10 seconds and try again. If the lid still does not open: check that the rotor has stopped turning, insert lid release tool into side hole (on right) and lever down. The lid will ‘pop’ open. Lid? The lid has opened during the run. The motor will now brake. After it has come to a complete stop you may open the lid. Check that the lid is correctly shut. If Lid? still showing please contact your service department. OPEn The rotor has stopped spinning. You may now open the lid. Press the ‘Lid Open’ button. tAcho? The rotor has not turned in 5 seconds. Check that nothing is preventing the rotor from turning i.e tall tubes or packaging. If tAcho? still showing please contact your service department. TROUBLESHOOTING rotor? K2 Series only. The rotor has not been recognised. Safety speed will automatically be selected. Try and run again, check its max speed. If rotor? still showing please contact your service department. baL? An imbalance has occurred. Check that the tubes are correctly placed in the rotor. If tubes are correctly placed and baL? still showing please contact your service department. 40 Lid Open Press when LED display indicates OPEn.

Tacho sensor Tacho connection to J1 (near C1/C23) Lid Locking Mechanism and Solenoid • The two point locking mechanism is released by a 12-volt solenoid, capacitor at 20 volts, for a brief period. • This method gives maximum power for a short period without the possibility of burning out the Solenoid Coil, by remaining on, thus by constantly pressing the lid open button, a wait message appears on the LED this is while the capacitor charges (approximately 4 seconds). • The lid open sensor is a V3 microswitch, wired normally open. • The actuation is on the latch arm; adjustments can be made only by removing the front panel and trimming the V3 microswitch arm. The switch is situated front right above the Solenoid (see Picture below). • The Solenoid plug is a 4 way connection to J5 on the Circuit Board (see Picture below) • Apart from adjustment to the Microswitch, or Lid latches (on the lid) dependant on wear. • No other maintenance is necessary Solenoid and Microswitch: Microswitch arm 48 Lid latch to lid (correct position aligned to side) Lid System Connection: Lid system plug J2 Imbalance Detector • The imbalance Detector is a V3 microswitch wired normally closed. • A break in the circuit actuates the motor brake and the rotor comes to a safe stop. • The circuit is 5 volt from the main board. • The adjustment is by two pozihead screws on the underside of the base plate. • Release and push forward or backwards to adjust. Imbalance arm NOTE: a 3mm gap should be between the stop and the detector arm for normal use. Imbalance plug to board position J1 (near C21) Correct gap (3mm) 49 Mains Inlet Filter • The Mains inlet is double fused, with an IEC Socket for the power source. • It is held in place with 2 Countersunk M3 Screws. • Fuses are 5 x 20mm 6.3 (TA) Slow blow only. R Version is 10 amp (TA) • Wiring to filter is shown as below. • Wiring to Inverter is EARTH to EARTH, BROWN to L1 and BLUE to L2/N Mains inlet wiring Mains connection to Inverter Blue (Neutral) Brown (Live) Brown (Live) Blue (Neutral) Filter To comply with EMC regulations a 5 amp filter is fitted. This has been tested and complies with radiated and transmitted specifications. Connections are as on the Filter and should NOT be reversed (see photograph) Blue (Neutral) Brown (Live) Buzzer and Fitment (optional extra) • The buzzer is a 12 volt type, fitted to the front panel by a tape backing. • The connection is to J3, a 3 pin connector. • The buzzer sounds at the end of the run, stays on for a few minutes and then shuts off (so as not to be intrusive) • No maintenance is necessary. Motor Connection to Inverter } BLACK 11 to TH1A BLACK to M1/U YELLOW BLACK 12 to TH1B BROWN to M2/V GREEN GROUP CONNECTOR BLUE to M3/W WHITE 50 Transformer and Connection • The transformer is a 12 volt 20Va type, held in position with two flat washers, spring washers and M4 nuts. This unit powers the circuit board (regulated down further to 5 volts), lid lock and buzzer. • The wiring from the top is Mains voltage (brown wires). Area dependent. • The two lower wires (as marked are 12 volt) DO NOT USE mains power here. • These 12 volt (blue wires) pass into a Molex two pin plug to J5 on the circuit board. Transformer position Transformer plug position J5 Rotor Recognition Sensor (K series only) • A Hall effect sensor, fixed to the motor top, senses magnet flux from placed magnets in the required rotor. • A Rotor must be used with the K Series. • The amount of small magnets per rotor are pertinent to the maximum speed of each rotor. • The sensor counts the flux number per rotation, advising a look up table and setting the rotors paramaters for safety. • Maintenance. Other than checking the distance from sensor to magnet (2-6mm max) no other maintenance is necessary. Rotor recognition sensor Connections to J1 near C22 51 K Refrigerated Series only: Temperature Probe • The Temperature probe is an AD592AN: IC Transducer. • Wiring is to the two outer legs only, the centre leg is removed. • The transducer is mounted in a Stainless steel M8 Shroud with Heat sink compound. The Assembly is then bolted in position to the outer rim of the bowl (as shown). • Twin wires are taken forward to the Circuit Board to socket J4 Replacement of Probe • After extracting the probe and replacing, the new probe will require calibrating. • RV1 and RV2 on the circuit Board will require “trimming” to the correct temperature. • A thermometer accurate to 0.5ºC will be required. • By placing the thermometer near the probe in the bowl, calibrate RV1 to 0ºC then RV2 to ambient, go back to RV1 to recheck. • For K280R a 7ºC offset is required and the K240R a 5ºC offset. These offsets are to allow for bowl mixing of temperature variation over its depth. Temperature probe connection to J4 Temperature probe housing to bowl Refrigeration (KR Series only) • The Compressor is a standard unit Electrolux GL60 PB charged with R134A gas at a charge 120Gms. An equivalent can be used that has the same footprint. • Capillary length is 3 metres of .031mm bore. • Suction line length is 76Cm of 5/16” tubing, the dryer is a 10gm type. • Fan is a standard mains type. • Wiring to the compressor is shown here. Mains power Fan power Refrigerated unit compressor from rear 52 Heater Wiring (KR Series only) • The Heater is a 5.77 metre coil of 30 Ohm shrouded wire. • This is wound between the Cooling coils and controls the temperature by pulsing on off via a solid-state relay (SSR1). • This is controlled by a PID system (Proportional, Integral, Derivative) for accuracy. Connection to board is as below. Mains wiring to connector is also shown.
