Assembly and installation instructions
21. Functional testing of connected assemblies
The KaController provides the option of checking the function of the
external units connected independently of the software application. The
function of individual assemblies, such as the EC fan, can be directly
activated and checked by means of inputs on the KaController.
The functional checks of the connected assemblies are called up and
performed by the following operating steps:
1. Switch off the KaController by:
Press the ON/OFF key or
Press the navigator for a minimum of 5 seconds or
Turn the navigator dial to the left until OFF appears
2. Call up the Parameter menu by pressing the navigator dial for a
minimum of 10 seconds. The display shows "Para" and then "CODE"
with the value 000 in sequence.
3. Select the password (code) 77 by turning the navigator dial and confirm
by pressing the navigator dial.
4. "L01" is shown on the display and the functional testing of the
connected assemblies can start.
Important:
The individual test steps are called up by pressing the navigator dial.
The standard view with "OFF" showing appears once the test has been
completed (L09).
* The control automatically detects the requisite sensors on the analogue inputs AI1 - AI3 using the DIP
switch settings. The respective display (L01-L03) flashes if sensors are faulty or not connected.
