User Manual RLSW®9 Increased operational reliability for your machine/system thanks to continuous monitor- ing of the sensor, the sensor elements and the connecting cable for short circuits and wire breaks during operation. In addition, the electronics are continuously monitored by internal test routines.
User Manual RLSW®9 4. INSTALLATION AND COMMISSIONING Installation and commissioning must be carried out by authorised and qualified personnel. The connection to the main supply (L, N) must be made via a protected circuit breaker with standard fuses. The general VDE regulations must always be observed (VDE 0100, VDE 0113, VDE 0160). If the potential-free contact is connected to a safety extra-low voltage, the connecting cables must be suf- ficiently insulated up to the terminal, as otherwise the double insulation to the mains voltage side may be impaired.
User Manual RLSW®9 4.2 Electrical connections / terminal assignment The electrical connections are located in the housing under the cover with the membrane keypad. The cover is opened by inserting a flat, approx. 4 mm wide screwdriver into the slot on the right and then pushing the screwdriver slightly inwards/leftwards.

User Manual RLSW®9 Further switching point setting options 1 (optional): Relative If the switching point is set to "flow%" under menu item 4: "Alarm", you will be prompted to set a number between 1 and 99 when you press Menu/T1. This number corresponds to the switch- ing point as a percentage of the set maximum flow, e.g: Maximum flow = 10 m/s, switching point 50%, real switching point is then 5 m/s.
User Manual RLSW®9 4.4 Menu settings You can access the setting mode by pressing and holding (approx. 3 s) the "Menu" button on the cover or T1 in the appliance itself. Please note that the number and type of menu items may vary depending on the specification and design.
User Manual RLSW®9 To finalise the changes, exit the menu under "Display ok" with "Save and exit", otherwise the data will be lost. If the dimension of the display is changed (e.g. from m/s to l/min), it is essential to readjust the switching threshold and, if necessary, the measuring range.

User Manual RLSW®9 Information on the RLSW®9 M8 with remote sensor The RLSW®9 is also available with a remote sensor. The supplied sensor has a connection cable with a length of 2.5 metres as standard (special lengths are available on request). This length must not be changed due to the calibration.
User Manual RLSW®9 5. MAINTENANCE INSTRUCTIONS The air flow sensor should be serviced at regular intervals, i.e. that when used in heavily the air flow sensor is cleaned if the media is contaminated. The following procedure is expedient: ▪ Dismantling the airflow monitor ▪...
