8. Programming
8.1 Selection of the mode of operation
Simple installation is possible through the selection of the preprogrammed mode of operation. This determines the basic
function of the device; factory setting
1.01 = speed controller (activation via 0-10 V signal).
The controller configuration is automatically carried out during selection of the application related mode of operation. The
factory presets in accordance with the mode of operation are based on many years of experience, which is suitable for
many applications. Under special circumstances, these can be individually adapted (
F Controller Setup: Controller
Configuration).
The purpose of the device is to reach and maintain the target values set. To accomplish this, the measured actual value
(sensor value) is compared with the adjusted target value, and the controlled value (modulation) is deduced from this.
1. Pay attention to the application examples and carefully determine the mode of operation.
2. Then changeover to the selected mode of operation.
