    Safety rules Safety rules • This machine is designed for water washing only. • All installation operations are to be carried out by qualified personnel. Licensed personnel are necessary for all electric power wiring. • The interlock of the door must be checked daily for proper operation and must not be bypassed.
  • Page 25: Mechanical And Electrical Design

    Mechanical and electrical design General The door and the electronic timer with display and keyboard are fitted at the front of the machine. All control and indicating components, i.e. relays, delay unit, etc are assembled under the top cover, easily accessible from the top of the machine for simplified servicing.
  • Page 26 Mechanical and electrical design Machine construction Panels The machines are equipped with a top panel and front panel made of stainless steel. Colored panels are made of phosphatized steel. For servicing purposes, the panels can be easily removed. Outer shell The outer shell is made of heavy gauge surgical steel and is attached to a Fig.

  • Page 28 Mechanical and electrical design Description The machine door lock consists of the following: Fig. • The locking unit, located behind the front panel below the detergent dispenser. The unit consists of a solenoid which locks the door, and two microswitches. Switch S4A indicates that the door is locked and switch S3 indicates that the door is closed.
  • Page 29 Mechanical and electrical design Door lock control unit The sole function of this control unit is to oversee the correct functioning of Fig. the door lock. The CPU board receives information from the motor control unit about motor rotation, and has its own level-monitoring device. The control unit also detects water level and motor speed through separate level measurement devices and the rotation guard (speed-monitoring device).

  • Page 42 Mechanical and electrical design Extraction Fig. During extraction, the motor speeds follow an extraction sequence which is always the same. This extraction sequence is used for all standard programs 991-999 for CLARUS machines. The table shows the extraction speeds during the various phases of the sequence, for various drum volumes.
  • Page 43 Mechanical and electrical design Imbalance measurement At the start of every extraction sequence the system monitors variations in the motor torque while the drum is operating at distribution speed. If these variations are too great, it indicates that the load is unevenly distributed in the drum.
  • Page 44 Mechanical and electrical design Supply injection valve Construction The valve has a single-inlet with either one, two Fig. or three outlets, each with its own solenoid coil. The body is made of heat-resistant polyamid plastic and the solenoids encased in water-tight plastic.
  • Page 45 Mechanical and electrical design Repair instructions Limescale can block the hole in the valve diaphragm and interfere with the function of the valve. It is therefore advisable to dismantle and clean Fig. the valve at certain regular intervals. The frequency depends on operating conditions and the level of contamination in the water.
  • Page 46: Inlet Valve

    Mechanical and electrical design Inlet valve The water inlets have brass bodies with larger Fig. cross section of the outlet in order to achieve a shorter filling time for the machine. Construction Fig. The valve housing is made of pressed brass. The spring-loaded plunger is made of stainless steel and located at its lower end.
  • Page 47 Mechanical and electrical design Description The drain valve is a motor-operated diaphragm Fig. valve which allows rapid emptying thanks to its large cross-section. This is a self-clearing design, Fig. so there is no need for a lint filter. Main parts of the valve: •...
  • Page 48 Mechanical and electrical design When the motor is activated and begins to rotate, the piston rod is turned upwards via the gear, the diaphragm is pressed upwards with the piston and presses against the valve seat: the valve closes. The connection for overfilling is connected to the upper part of the wash drum, water and foam are diverted straight to the drain if the intake valves or level control should malfunction.
  • Page 49 Mechanical and electrical design Tensioning of return spring With the valve housing removed: - Turn the return spring so that the “tongue” of the spring is resting against the stop screw. - Position the valve housing over the return spring so that the pin on the spring will fit into the recess on the piston rod.
  • Page 50 Mechanical and electrical design Soap supply box The three-compartment soap supply box is located at the top of the machine. Fig. Viewed from the front, the compartments marked with figures 1, 2 and 3 are used as follows: Compartment 1 This compartment is used for adding detergent directly to the wash at the beginning of a cycle or at any time during the cycle when extra supplies are required.
  • Page 51: Operating Instructions

    Operating instructions Operating instructions The Emerald Series program unit controls the various functions of the machine in a certain time sequence with the aid of seven built-in standard programs. The standard programs can also be modified by selecting various options. By selecting options, the user has access to programs for all types of wash loads and degrees of soiling.

  • Page 56 Programming Coin-operated machines In coin-operated machines the prices for the various programs have to be programmed in. Values from the coin mechanism (the accumulated value) can be read out with the aid of the service program. If a machine is fitted with a coin mechanism after its original installation the relevant electronic circuitry will have to be activated before the prices can be programmed in.
  • Page 57 Programming Codes 91 and 92 are used to store the values for coin slots 1 and 2. For mechanisms with only one slot, only code 91 is used. The values to be stored are the ratio of one coin to the other. For example: if the coin slots are for a 10 cent coin and a 50 cent coin.

  • Page 85: Maintenance

    Maintenance Maintenance Preventive maintenance has been reduced to a minimum by the careful design of reliable components and material. However, the following measures should be taken at regular intervals and in proportion to the hours of service. Make certain that all electrical power to the machine is shut off before removing top or rear panels.
  • Page 86 Maintenance Weekly • Remove hose from drain connection and clean inside drain valve. Every three months • Remove the cover plates of the machine and Fig. check that the V-belt of the motor is undamaged and correctly tensioned. • Check that all tubing, piping and connections are free from leaks.
  • Page 87: Trouble-Shooting

    Trouble-shooting The purpose of the trouble-shooting guide is to facilitate the location an correction of the most common machine problems. Before the top panel is removed, power to the machine is to be switched off at the main source or at the separate circuit breaker. At each trouble-shooting attempt, the plug in connectors on the control panel should be moved in and out in order to eliminate improper contact due to faulty connection.
