Connection and commissioning must be performed by properly authorized and qualified personnel!
Connection to mains supply (L, N) must be made by means of a protected isolating switch with the usual fuses. As a matter of principle, the General VDE Regulations must be complied with (VDE 0100, VDE 0113, VDE 0160). If the potential-free contact is connected to an extra-low safety voltage, sufficient insulation must be provided for the connecting cables up to the terminal, since otherwise the double insulation to the mains voltage side may be impaired. The current load capacity of the potential­free contact is limited to 6 A. Therefore, the electrical circuit of the potential-free contact must be protected by a 6.3 A fuse.
Commissioning
• Install and connect the flow controller in accordance with installation instructions and conditions.
• Set trimmer „Sensitivity“ to minimum sensitivity (left limit stop).
• Connect mains voltage. The green LED lights up. Set nominal rate of flow.
• Slowly turn coarse potentiometer „Sensitivity“ clockwise until the yellow LED lights up and the signal output
switches. In order to avoid erroneous switching at low changes of flow, turn the fine potentiometer slightly past the switching point.
• Check this setting after about 2 – 3 minutes and, it required, readjust by turning the fine potentiometer.
Trouble shooting
Problem Possible Cause Corrective Action
KSW.. does not function at all None or wrong mains voltage
KSW.. does not detect flow Sensor not installed correctly Check installation conditions
KSW.. exhibits changed tripping behavior
KSW.. switches at rapid temperature increase of the medium

Sensor heavily contaminated by the medium
Temperature gradient is outside of technical specifications
Check mains voltage and connection
Carefully clean sensor with water
Turn potentiometer „Sensitivity“ slightly further clockwise. Check temperature gradient of the system.

The flow controllers of the series KSW.. are used to monitor flow speeds of liquid and watery media within the stated technical specifications. The main area of application is the control of pumps and cooling circuits.
Proper use
The flow controllers of the series KSW.. are intended to be used in monitoring of flow speeds of liquid and watery media within the specified technical data. The main area of application is the control of pumps and cooling circuits.
Function principle
The flow controllers of the series KSW.. function according to the calorimetric principle. The units are switched when a certain pre-selected threshold value is reached.
Flow > / = threshold value signal output switched yellow LED „Flow” is on Flow < threshold value signal output not switched yellow LED „Flow” is off

Installation Conditions KSW..
To avoid malfunctions, the following points should be observed.
• The tip of the sensor (15 mm) should be as close as possible to the center of the pipe and must be within the full flow of the gaseous medium.
• In case of deposits or air inclusions in horizontal pipes the KSW.. should be installed sideways.
• In case of vertical pipes, the direction of flow should be upwards.
• Maintain a free inlet distance of 5xD upstream of the sensor and 3xD outlet distance downstream of the
sensor.
• Screw in the flow controller by means of the hexagon of the sensor housing only.
• The flow controller can be installed in any position.
