3 Product overview

3.1

Application

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 is deduced from this.
The device has two separate control circuits and two sensor inputs (0 - 10 V, 4 - 20 mA, KTY 81-210,
PT 1000).
Speed controllers for fans or fans with an integrated controller can be activated via the 0 - 10 V signal
or the parallel option of the MODBUS Master interface.
3.2

Maintenance

The device must be checked for soiling and, if necessary, cleaned in periodic intervals.
