Mechanical and electrical design
The washing machines are controlled by a microprocessor program unit. This
provides several major advantages:
• The control of times, levels and temperatures takes place with considerable
precision and flexibility
• The large character display provides detailed information in clear text about the
different wash programs, the machine's different activities, relevant wash times
and temperatures.
• The user is able to program new wash programs and adapt the programs exactly
on the basis of previous experience, different kinds of materials, the degree of
soiling etc. Depending on the length of the program, up to 90 different programs
can be programmed. Refer to the separate appendix for programming.
• When supplied, the machine is provided with a number of standard programs. The
maximum number is 9.
• Machine safety can be maintained at a very high level through continuous
monitoring and integral safety checks.
• The machine has an integral service program for testing machine functions.
By using a special temperature-controlled cooling process before the first rinse cycle,
mixed textiles can be washed at high temperature without the risk of creasing.
To avoid high mechanical stresses during the spin cycle, the machine is fitted with an
automatic imbalance sensor. The spin cycle is discontinued if imbalance occurs, the
machine is filled with water and the machine operates with a reversing action to
redistribute the wash goods. The drain valve then opens, the machine operates at
distribution speed and a new spin cycle starts.
The machine can also be operated manually.
The electronic controls together with carefully considered machine design based on
long experience also provide:
• simple installation and a long service life.
• a low noise level thanks to the soft suspension of the drum and its dampened
free-swinging operation.
• very good de-watering effect as a result of the high speed spin cycle and the large
drum diameter.
• low water and power consumption in relation to capacity.
• extreme ease of servicing.
The FC-machines are equipped with a frequency control and a multi-speed motor.
This gives advantages such as:
• a machine with possibilities to a very smooth drum rotation through a slow
acceleration of the drum.
• wash with reduced speed.
• quiet operation.
• improved distribution of the load.
