9.2 Temperature chart of the start-up stages
When started up, the EC-30C carries out a self-test to check the main components of the
unit.
The self-test consists of six testing steps. Each of the test steps is symbolized by a smiley
icon. After successful self-testing the unit enters the starting phase and starts cooling.
When the display shows a ‘Test failed’-icon, the unit has detected an error. The cooler will
not enter the start-up phase.
If the self-test has failed, the display alternates between the screen with the smileys and
the service screen. These screens will remain on the display until the problem has been
solved.
Generally in a cases like this the unit has to be sent to M&C for check-up and/or repair.
Please contact our service department by phone before sending the unit.
Note
Please find more details about the self-test on page 19 chapter ‘7.3
Self-monitoring after powering-on the unit’ .
After successful testing, the unit starts the cooling process. It is carried out in several differ-
ent stages, shown in the following phase diagram.
