5.5 Setting up the channels

Wizard

The Wizard performs a test with minimum power consumption to determine whether the channel can be switched on safely. There are options for selecting the operating mode, setting setpoints and special functions, grouping, performing a controller adjustment (adaptation) and starting the channel automatically after a successful test. Setpoints and other settings are reset to the default settings. You can customise the basic settings in advance in the device settings (see Section 9.2.3, “Basic settings”). The channel settings can also be customised after running the wizard.

Typical errors are recognized:

• Short circuit
• Sensor break
• Heating short circuit
• Polarity error
• No load

Adaptation

The channel is heated for a certain time or to a certain temperature and then cooled down. New control parameters are now determined from the measured data.

Diagnosis

The selected channels are subjected to a complete diagnosis. This means that fault current, current consumption, sensor polarity and thermal coupling are tested. In addition, an adaptation is carried out and the nominal output level is determined.
