If the sensor cable is laid in a duct together with other live cables (e.g. motors or solenoid valves), we recommend shielding the sensor cable (connect a shield). Sensors with shielded cables are available as accessories from SEIKOM Electronic. page 6... -
Page 7: Installation
Operating instructions NLSW®45-3 SIL1 Analog ▪ To avoid malfunctions, the sensor cable must be extended with a cross-section of at least 1.5 mm². The maximum cable length should not exceed 50 m. ▪ Maintenance instructions: Regular cleaning is necessary depending on the application. Maintenance intervals must be determined and specified as required 4.2 Installation It is mounted using the PG7 thread on the sensor housing. -

Page 10: Typical Output Values
Operating instructions NLSW®45-3 SIL1 Analog Set the "Start delay" potentiometer [Delay] (orange) to the desired start-up delay time of approx. 5 ... 60 seconds (left stop approx. 5 seconds/right stop approx. 60 seconds) Apply mains voltage. The green LEDs light up. The device is ready for operation within 2 seconds. -
Page 11: Switching Point Setting
Operating instructions NLSW®45-3 SIL1 Analog If the NLSW®45-3 SIL1 Analog is set to a different measuring range, the curve scales accordingly. For example, Iout at a maximum set air flow of 10 m/s or 25 m/s is approx. 20 mA in each case. The media temperature has only a negligible influence on the current or voltage output and switching point. -
Page 12: Servicing And Maintenance
Operating instructions NLSW®45-3 SIL1 Analog Small flow change in the low flow velocity range: The switching point can be selected with a greater distance to the measured value of the normal flow, as the measured value change is large when the flow changes. -
