Tachometer
• The Tachometer is a horseshoe LED type, 5volt, sensing dark and light current off the butterfly interrupter.
• The only adjustment necessary is to make sure the sensor is central to the horseshoe array.
• Apart from a light haired brush to the sensors, to remove dust no other maintenance is necessary.

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

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.

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

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

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.

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.

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.

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.

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.

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.
