Service Manual Programme unit Fig. 3 Fig. 4 3 3. Machine presentation The control panel has a rotary switch for selection of fixed machine programmes and a combined start/pause button with rapid advance. 3 Programme unit The programme unit controls the water valves, drain valve and heating via the communication card in the rear control unit. This unit can also be connected to send control signals to external units for detergent pumps.
3 3. Machine presentation Door lock Fig. 5 Fig. 6 Service Manual 5 Door lock control The door lock is an electro-mechanical type with double safety switches. The lock is bi-stable, i.e., it needs to receive an active pulse from the control in order both to lock and unlock the door. A separate printed circuit board, called door lock control, can be fitted onto the programme unit. This board controls locking and unlocking. The card has separate checks for empty drum and stopped drum.

Service Manual 11. Regular maintenance 11 To keep your machine in proper working order, follow the preventive maintenance recommendations provided below. The maintenance interval should be adjusted according to machine usage. The suggested schedule assumes an 8 hour work day, and a 5 day work week.. Daily • Check the door and door lock: - Open the door and try starting the machine. The machine MUST NOT START. - Close the door, start the machine and try opening the door.
11 11. Regular maintenance - Inspect all internal hoses, seals and gaskets for signs of leakage. Repair as necessary. - Check that water inlet screens are clean of debris. Dirty screens result in longer fill times, which reduce productivity. - Inspect the drive belt. Adjust the tension or replace if necessary (see section 30. Motor). - Check that there are no signs of leakage on the floor beneath the machine. Locate and repair any leak.

41 Fig. 2 Service Manual 41. Coin-meter Switch S1 is used for setting the ratio between the two coins. If the coin meter only have slot for one coin, all switches shall be placed in OFF position. 2 The following combination is available (ON = 1). Switch 1 0 1 0 1 0 1 0 2 0 0 1 1 0 0 1 3 0 0 0 0 1 1 1 4 0 0 0 0 0 0 0 Ratio 1:1 1:2 1:4 1:5 1:10 1:20 2:5 Example Ratio 1:2 Value 2 is twice the value of 1. Ratio 1:4 Value 4 is four times the value of 1.
Service Manual 41 41. Coin-meter Programming the current price 3 Programming is carried out on the switch unit, where the switches correspond to values from 1 to 64 when they are set on position ON. First calculate the value I which the switches will give together and then set the switches so that they will give this number. OFF ON I = (P x A)/V where 1 2 3 4 5 6 7 P = price per program, 1 2 4 8 16 32 64 A = first number in coin ratio. When counter unit is for single coin insertion A is always 1.
