LIBERO LINE FRY TOP INDUCTION
4.5.3.5 S4, COOKING TOP COUPLING
This test is made to check the quality of the coupling between pots and generator, the function is more useful
on HOB appliances.
Fry tops do not need to do this test this because the cooking surface is already coupled with the generators
and the quality of the bonding is guaranteed by the materials of the cooking top that is built on the appliance.
However, a quick explanation of how this test works.
Service Utility S4: Power supply v cooking plate coupling rate (pot coupling rate).
POW
Hob Control. Also referred as “Power Board” (POW).
TESLA Single-phase, generator, 3500W
The test is done in three steps:
•
Step 1: The POW measure the main power supply voltage without load (power request zero).
•
Step 2: On FRYTOP appliances the max power is applied to all coils (power level 9) to every coils
(generators) belonging to the cooking area. Real generated power is estimated measuring the current on the
coil and a coupling factor is showed as:
Coupling factor % = (Estimated power / Requested power) %
Where estimated and requested power is the sum of the values measured on every single coil (generator)
belonging to the area under test.
Visualization is done as P x where:
P0
→
0% to 9% P5
→
50% to 59%
P1
→
10% to 19% P6
→
60% to 69%
P2
→
20% to 29% P7
→
70% to 79%
P3
→
30% to 39% P8
→
80% to 89%
P4
→
40% to 49% P9
→
90% to 100%
•
Step 3: Main power supply voltage is measured with the cooking zone under test at max power.
