* Conﬁguration dependent. Non-SIL2 fully conﬁgurable. SIL2 ﬁxed conﬁguration and only applicable for High Level sensor ** For failure types please connect the device to the Bluetooth App, enter fault state mode, and read the failure type *** Fault can be detected at any detected level, ie. 2 or all 3 lights on

Not recommended in these applications because

1) A High Level Alarm may not be registered at a power failure

2) A Low Level Alarm may not be registered at a power failure

- The LLS device should only be used with approved media listed under General speciﬁcations. Use with other medias must be validated by Danfoss before installation.

- Verify that the installation and operating conditions of the device respects those speciﬁed in this guide, especially concerning the supply voltage and environmental conditions.

- All service and maintenance operations must be performed by qualiﬁed personnel.

- Installation must comply with local standards and legislation.

- Before carrying out any maintenance operations on the device, disconnect the device from the main power supply.

- Before unscrewing the LLS device from the pipe or tank ensure that pipe or tank is empty and not under pressure.

- Liability for injury or damage caused by incorrect use of the device lies solely with the user.

- Depending on the application, the metallic part of the instrument may be hot or cold.

- If media detection or non-detection by the level switch could generate a hazard the SIL version and speciﬁc instructions described in the safety manual (periodic proof test) should be used. The SIL safety manual can be downloaded from Danfoss web site or by scanning the QR code below.
