INSTRUCTION
HANDBOOK
1. General
A very high working safety level of the machine is achieved thanks to a continuous monitoring
and built-in safety devices.
Even the compound textile fabrics can be washed at a high temperature with no crumpling risk
thanks to a special cooling process before the rinsing cycle.
In order to avoid an excessive mechanical fatigue during the hydro-extraction process, the
machine is equipped with an unbalance detector. If the latter detects the least unbalance of the
load, the hydro-extraction cycle is interrupted and the machine fi lls with water to make a new
distribution of the linen possible.
The machine then resumes the distribution speed and another hydro-extraction cycle begins.
The machine can also be controlled sequence by sequence and is equipped with a keyboard
for the manual control of certain functions.
Note about the A.C. power
• According to the EN 60204-1:1997 standard, the machine is provided for AC supplies
corresponding to the extracted caracteristics below :
4.3.2 AC supplies
Voltage:
Steady state voltage : 0,9…1,1 of nominal voltage.
Frequency:
0,99…1,01 of nominal frequency continuously.
0,98…1,02 short time.
Harmonics:
Harmonic distorsion not to exceed 10 % of the total r.m.s. voltage between live conductors for
the sum of the second through to the fi fth harmonic. An additional 2 % of the total r.m.s. voltage
between live conductors for the sum of the sixth through to the 30th harmonic is permissible.
Voltage unbalance:
Neither the voltage of the negative sequence component nor the voltage of the zero sequence
component in three-phase supplies shall exceed 2 % of the positive sequence component.
Voltage interruption:
Supply interrupted or at zero voltage for not more than 3 ms at any random time in the supply
cycle. There shall be more than 1s between successive interruptions.
Voltage dips:
Voltage dips shall not exceed 20 % of the peak voltage of the supply for more than one cycle.
There shall be more than 1 s between successive dips.
