Installing/mounting General instructions Ambient conditions The transmitter is suitable for standard and extended ambient conditions acc. to DIN/ EN/IEC/ANSI/ISA/UL/CSA 61010-1. It can be used indoors as well as outdoors. Process conditions Note For safety reasons, the transmitter must only be operated within the permissible process conditions.
Installing/mounting 4.3 Mounting instructions Figure 4.1 Mounting via a mounting bracket Mounting instructions Installation position When mounting the device, keep a distance of at least 200 mm (7.874 in) from the vessel wall. If the device is installed in the center of dished or round vessel tops, multiple echoes can arise.

Installing/mounting 4.3 Mounting instructions Reference point Figure 4.3 Reference point Inflowing medium Do not mount the transmitters in or above the filling stream. Make sure that you detect the medium surface, not the inflowing product. Figure 4.4 Mounting of the radar transmitter with inflowing medium Mounting nozzle For nozzle mounting, the nozzle should be as short as possible and its end rounded.

Access protection Bluetooth radio interface Devices with a Bluetooth radio interface are protected against unwanted access from outside. This means that only authorized persons can receive measured and status values and change device settings via this interface. Bluetooth PIN A Bluetooth PIN is required to establish Bluetooth communication via the adjustment tool (smartphone/tablet/notebook).

Setup with smart device (Bluetooth) Connecting Connecting Start the adjustment app. The smart device searches automatically for Bluetooth- capable transmitters in the area. The devices found are listed. Select the requested transmitter in the device list. Authenticate When establishing the connection for the first time, the operating tool and the transmitter must authenticate each other.
Operating To configure the device: Download and install the SITRANS mobile IQ app from the App store to your mobile device. Launch the app. Devices in range will appear. Click on the device you wish to connect to. On first connection, a PIN code shipped with the device needs to be entered (see Device Bluetooth and SITRANS LR100 Operating Instructions, 08/2020, A5E49829004...

Diagnostics and troubleshooting Maintenance Maintenance If the device is used properly, no special maintenance is required in normal operation. Precaution measures against buildup In some applications, buildup on the antenna system can influence the measuring result. Depending on the transmitter and application, take measures to avoid heavy soiling of the antenna system.
Diagnostics and troubleshooting 9.3 Diagnosis, fault messages • Signal processing Fault rectification The first measures are: • Evaluation of fault messages • Checking the output signal • Treatment of measurement errors A smart device (smartphone/tablet) with the adjustment app or a PC/notebook with the PDM and the suitable EDD offer you further comprehensive diagnostic possibilities.
