Sub menu Description
Sensor test The following sensors are tested:
• Lower opto: status On or Off.
To carry out the test of the sensor, an object, eg. a cup
or a pot must be placed on the platform or held in front
of the sensor and removed again. The status should
be “On” when the sensor detects an object, and “Off”
when it is removed.
If the status of the sensor does not switch from ‘On’ to
‘Off’ or vice versa when an object is inserted or
removed, it is an indication that the switch or sensor is
defect or not positioned correctly. Check the sensor
and replace if necessary.
See how sensor is replaced in chap. 5D, page 5D-1.
