PLEASE ENTER THE FOLLOWING INFORMATION AS IT APPEARS ON THE MACHINE(S) DATA PLATE(S). MACHINE TYPE OR MODEL MACHINE SERIAL NUMBER(S) ELECTRICAL CHARACTERISTICS: ________ VOLTS, _______ PHASE, ______ HZ. MAKE CERTAIN TO KEEP THIS MANUAL IN A SECURE PLACE FOR FUTURE REFERENCE. II NOTICE TO: OWNERS, OPERATORS AND DEALERS OF WASCOMAT MACHINES IMPROPER INSTALLATION AND INADEQUATE MAINTENANCE, POOR HOUSEKEEPING AND WILLFUL NEGLECT OR BYPASSING OF SAFETY DEVICES MAY RESULT IN SERIOUS ACCIDENTS OR INJURY. TO ASSURE THE SAFETY OF CUSTOMERS AND/OR OPERATORS OF YOUR MACHINE, THE FOLLOWING MAINTENANCE CHECKS MUST BE PERFORMED ON A DAILY BASIS. 1. Prior to operation of the machine, check to make certain that all operating instructions and warning signs are affixed to the machine and legible. [. . . ] The stator and the rotor consist of plates, insulated from each other and welded together. The stator is provided with slots in which the 2-pole and 18-pole windings are wound. The windings are impregnated with a temperature-resistant sound-insulating resin varnish according to class B. The ball bearings are permanently lubricated. Construction of single-phase motor Single-phase motors have an 18-pole winding (wash-speed) the same as three-phase motors, using a continuously connected capacitor, while the 2-pole winding (extract-speed) is a specially designed winding with both a continuously connected capacitor and a starting capacitor. 1729 40 Function of 3-phase motor When the stator winding is charged, a magnetic field will occur, which in turn will rotate the rotor at a fixed RPM depending upon the number of poles in the winding. The 18-pole winding gives the wash speed and the 2-pole winding the extract-speed. When operating with load, the speed deviates slightly from the synchronous (no-load) speed. This difference is called the slip and is usually expressed as a percentage of the syncronous speed. The motors will work satisfactorily at nominal voltage +10%-15%. Function of single-phase motor When the stator winding is charged without a capacitor, two counteracting magnetic fields are created. When a capacitor is connected, it will displace one of the two magnetic fields adding it to the other, creating a torque turning the rotor in a specific direction. The RPM is the same as for the 3-phase motor. 1154 24 Mechanical and electrical design Principal wiring and points of measuring on single-phase motors. Fig. 41 The numbers at the connection points refer to the terminal numbers at the motor connector plug. The numbers in circles indicate points of ampere measurements. 41 FL125 208-240 V 60 Hz single-phase 1700 Mechanical and electrical design 41 25 FL185 208-240 V 60 Hz single-phase 1730 26 Mechanical and electrical design 42 Motor connections Fig. 42 1, 2 and 3: wash speed (18-pole winding). 4, 5 and 6: extract speed (2-pole winding) 7 and 9: motor overload protector. Motor overload protector The motor is equipped with two self-resetting, thermal overload protectors, situated one in each of the windings of the stator. The protectors are connected in series and will trip at a temperature of 120°C (248°F) (3-phase) or 130°C (266°F) (single phase). In the event the protectors fail but the motor remains otherwise undamaged, an overload protector may be mounted in the control unit of the machine. Before making such installation check to ascertain that the windings are not damaged. A burned out motor can be re-wound. Blue White Black LOW SPEED Blue Black White HIGH SPEED Overload protector NOTE Before connecting a separate overload protector consult the local code. Single-phase machines are also equipped with a manually set overload protector mounted on the extract relay in the control unit. This overload protector protects the motor during the start-up of the extraction. 0304 43 Removing the motor Fig. 43 · Remove the drain valve (1) from the long shaft by pulling it straight up. · Remove the tensioning unit (2) on the rear of the motor. [. . . ] · Wipe the outside of the machine. · When the machine is not in use, leave door slightly open to allow moisture to evaporate. 1207 Weekly · Remove the hose from the drain connection and clean the inside of the drain valve. Every three months Fig. 76 · Remove the rear panel of the machine and check that the V-belt of the wash motor is undamaged and correctly tensioned. · Check that all tubing, piping and connections are free from leaks.
