Mounting of sensor (F9)
Mount sensor so that airflow is passing through the cross-hole in the sensor shaft. The wire length between sensor and monitoring de-
vice should not exceed 100 m. If sensor cable is laid in one duct together with current-carrying lines (e.g. supplying motors or solenoid
valves), we recommend shielding sensor wires. The sensor must be connected with the flow monitor according to the connecting dia-
gram. Interchanging connections will cause malfunction.
Setting (all types):
The flow velocity to be monitored is preset at the »Flow rate« potentiometer on the circuit board inside the device (red LED lighting). The
red LED goes out as soon as flow velocity drops below the preset value and does not rise back to the value to be maintained within the
preset switch-off delay. Set trimmer »Hysteresis« so that according to flow conditions (smooth or turbulent flow), restless switching
behaviour is avoided and without variation spread getting too wide. Reduce or cut off flow generation for checking flow monitoring. The
red LED extinguishes and the "Flow" output relay drops out while the »Alarm« relay is activated. By pressing the Reset button, the device
is reset to its initial condition.
Devices with start bridging (KLSW 5 ⁄ 6)
Applications exist, where ventilator motors need a long run-up period so that the required flow (depending on the setting of the device's
sensitivity) will be available not until run-up is completed. During run-up, the flow monitor could switch to failure. On the KLSW 6, adjustable
start bridging (2 – 120 s) is integrated, bridging the start-up phase. During this period, output relay »Flow« is activated, the red LED »Air
flow« lights up. Thereby, the device acts as if flow would exist so that switch-off is avoided. We recommend to switch on devices with start
bridging together with the flow generator, as bridging time is only activated at the time mains voltage is switched on. When monitoring
device is switched on earlier, the internal time might have expired before flow is strong enough.
