Empty Run Test Data Mp-Lab - Electrolux FOM 71 CLS Maintenance Manual

FOM 71 MP-Lab
Empty run test data
During the CLS MP-Lab ring test, data was obtained from a number of laboratories.
This data is useful when checking that the reference machine in the laboratory is
performing as expected.
Please note: This data is obtained from runs with an unloaded machine. Therefore,
the energy and process times obtained here cannot be compared with the same
parameters applied during a test series carried out with a loaded machine. However,
empty test runs are not affected by load differentials or detergent batches and will
only produce results that are specific to the machine.
Table 1 below shows the estimated/defined values for Cotton 60°C, as well as av-
erage values from the RRT 2008 ring test.
The RRT 2008 average values were obtained from the RRT 008 IEC/CENELEC/CE-
CED ring test. These values are based on empty run tests undertaken at 15 different
laboratories.
The definitions used in Table 1 differ from those given in IEC 60456 and below are
applicable to Table1.

Time from the start of first filling to the start
of the retardation phase at the end extraction
sequence.
The time until the heating relays have been
switched on during the different heating peri-
ods.
The time from start of first filling until the start
of first rinse water supply.
The first filling time (26 litre). From closure of
door lock relay to end of filling.
The temperature of the supplied cold water.
The temperature at the time the heating relay is
switched off after reaching the 40ºC enzyme
step.
The temperature in the bath just
prior to the heating up to 60ºC.
