The machine lid is on a slewing arm, which is swung across the drum opening and then pressed down towards the drum. A microswitch in the control unit and also a Reed element in the C240/C240R and C260/C260R models check that the lid is closed before the machine will start. -
Page 11: Periodic Maintenance
Service 11. Periodic maintenance manual The following maintenance routines should be adhered to, to ensure satisfactory and safe operation, and to prevent service stops. The service intervals set out here are suitable for machines in normal use, for example in a communal laundry in an apartment building. The intervals should be halved if the machines is used intensively, e.g. - Page 13 Service 12. Functions sequences manual Functonal diagram for hydro-ectrator 487 03 29 91 12.1...

An auxiliary tranformer is supplied with two of the line voltage phases and steps down the mains voltage to 24 V control voltage. The auxiliay tranformer is protected by two fuses, one on the primary side (F1) and one on the secondary side (F2).

Functions sequences Circuit diagram 489 50 01 77 has been used in describing the function sequence in this section: This diagram is in principle identical to all the other circuit diagrams since the control voltage is 24 V AC 50/60 Hz. Start of extraction The machine starts extraction when the operator presses the START button on the control panel.

The sensor arm of the microswitch (SW3) is activated if there is load imbalance, and it in turn sends a signal to the circuit board (S2:2) for activation of the braking function and subsequent possibility of lid opening function.

Page 31: Lid And Lid Lock
To prevent the machine from being able to start with the lid open there is a microswitch which detects when the lid lock is engaged. Reed elements in the lid (on the C240/C240R and C260/C260R) sense when the lid is pressed lock down towards the deck. - Page 32 Service manual 29. Lid and lid lock Reed element C240, C240R, C260 and C260R General The function of the Reed element is to check that the lid is properly closed before extraction can start. A complete Reed ring consists of two Reed elements, set the ring itself, beneath the deck.

To reduce motor noise and vibration the entire drum unit has rubber dampers. On flexibly- mounted models this damping is provided by either eight or ten rubber straps, while the drum models this of R- models is mounted on two relatively rigid rubber bushings.

Service 30. Motors manual Fault-tracing Motor does not run at all. • Check the power supply to the motor. Check the motor´s quick connector. • Check the motor windings with an ohmmeter for short-circuit or failure. • Check that the motor shaft can be turned. If it can´t, the probable cause is bearing failure. - Page 37 These are two methods of mounting the drum unit in the frame: one for the flexibly-mounted type, the other for R-model. • In the flexibly-mounted models (C240 and C260) the drum unit is suspended from rubber straps: 8 or 10 according to type.
