RHEASREG KLSW 3 ⁄ KLSW 4
Series KLSW electronic airflow monitors are used for monitoring ventilators and dampers, for flow-dependent monitoring of humidifiers
and electric heating registers according to DIN 57100, part 420, or for applications in connection with DDC systems. Function: After
applying operating voltage (green LED lighting) and building up the desired flow velocity (yellow LED lighting) within the starting delay,
the »Alarm« relay is activated and the subsequent device is released. Sometimes detrimental heating ⁄ humidifying without air discharge
is so avoided. In case the necessary airspeed is not reached within the starting delay, the »Alarm« relay drops out.
Contacts 12 ⁄ 11 close. When preset flow rate is reached again, the »Alarm« relay is reactivated.
Contacts 11 ⁄ 14 close. By pressing the Reset button, the device is reset to its initial condition.
