Mode and signal input

Information
Simple installation is possible through the selection of the preprogrammed mode of operation (
Start-up)
This determines the basic function of the device; factory setting
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 (
"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.
By selection of the mode the function for control circuit 1 is determined, this influences the following outputs (factory setting):
1. Analog output "A1" 0 - 10 V with function
2. MODBUS Master interface
