1. Warnings Devices in this manual are not to be used in an Ex-area or environment which requires devices to meet the ATEX directive. If such device is required, please seek contact with our local sales representative. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation.
IC Compliance: RSS General (English) Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.

5 Disassembly and assembly instructions It is recommended to loosen and tilt the antenna to horizontal possition before opening the top cover. When assembling it is recommended to use SMA torque wrench to avoid damage from over tightening the antenna connector. Before opening the top cover be aware that the top cover holds O-ring sealant, which could drop off when performing the opening procedure. To open the top cover: 1. Tilt the lever outwards to snap the locking pin loose.
2. or unscrew the locking screw, if lever is not used for locking.
6 Replacing Battery 3. Detach the wire of the battery holder kit from the transmitter. 4. Loosen 2 pcs of screws used to fasten battery holder kit to battery holder plate.
5. Replace the battery. (Note: positive pole of the battery is at the end of red wire.
7 Detaching Transmitter 6. Disconnect battery cable if not disconnected. 7. Disconnect all wires from transmitter. 8. Remove the antenna.
9. Loosen and remove hexagonal cable adapter. 10. Loosen and remove the hex nut from SMA connector. The washers, antenna adapter and bushing rubber behind it will become loose, remove these parts. 11. Loosen 2 pcs of screws which are used to fasten the transmitter plate to frame. 12. Remove the transmitter and the sensor flange by lifting from the transmitter.
13. Note that there are 2 pcs of locking washers under the transmitter. They are used to lock the sensor flange to transmitter. 14. Remove the locking washers to remove the sensor flange from transmitter. Replace the transmitter. 15.
8 Sensor connections Transmitter has two inputs S1 and S2 in which temperature sensors or linear resistors can be connected. Transmitter has one AUX-input in which analog signal can be connected. Temperature sensors can be either Pt100, Pt1000 with 2-, 3- or 4-wire connection or thermocouple type E, J, K, N, R, S, T, B, L or U. Analog signal can be within current range 0...20 mA (0...23 mA) or voltage 0...10 V (0 - 11 V).
Cable colors according to IEC 584, except U- ja L-types according to DIN 43710.
9 Installation Installation configuration is application specific, in example the depth of the pipe measured, sensor type, and other mechanical parts in the assembly will define the final installation dimensions. Simplified installation example is illustrated in the picture below: 10 Spare parts Product code 5078683 5103996 5108800 5078690 5084342 5083211 5103294 Name Antenna 90 degree angle 868MHz Antenna straight 868MHz Antenna 90 degree angle 915MHz Battery 3.
