Door
Fig. The door is mounted on a special anchor plate
1which sits on the machine’s outer drum. The door glass is fitted in the door with only a door seal which also is tightly fit directly against the outer drum when the door is closed. The glass is not glued-coated making it easy to replace.
Door seal leakage
Fig. If the seal is not torn or damaged in some other
2way, the cause of the leakage could be decreased elasticity of the seal. Place a 4-7 mm sized O-ring around the entire seal in the seal slit (see illustration).
If the leakage persists, change the seal.
Safety lock
Fig. The safety lock is mounted on a circuit card with a
3contact for quick connection. The following is on the circuit card:
•the lock plate against which the safety lock knob locks the door.
•the microswitch which indicates that the door is closed.
•a lock unit which keeps the door from opening when the machine is in operation. This unit consists of:
-a double functioning solenoid
-a delay unit with a bimetal spring
-a lock bolt which can be controlled by both the solenoid and the delay unit.
-a catch which keeps the lock bolt from locking when the door is open. The catch also controls a microswitch.
