9. Adjusting the leak sensor
The functionality of the leak sensor should be checked once a year.
Perform the following test:
The device is switched on.
The device is standing vertically with the door closed.
The device runs at a temperature between 20-30°C.
Syringe
Methanol: 25 µl and 100 µl
Cellulose
Procedure
Process
1.
Put the methanol with the syringe on a piece of cellulose.
2.
Immediately place the cellulose into the interior of the thermostat.
3.
Close the door.
25 μl methanol: No alarm is triggered
100 μl methanol: Alarm is triggered
Note:
Open the door between the two tests for a few minutes to evapo-
rate the methanol of the first test.
If this test does not bring the desired results, connect the device to the
service tool software. Set the “Leak Value” (1) by adjusting the “Hardware
LS Sensitivity” (2) gradually in the service tool software. By increasing
the value more sensitivity and by decreasing the value less sensitivity is
achieved.
