1 Introduction
1.1 Safety information
General information
This manual contains information that must be observed in the interest of your
own safety and to avoid damage to assets. This information is supported by
symbols which are used in this manual as follows.
Please read this manual before commissioning the device. Keep the manual in a
place accessible to all users at all times. If difficulties occur during
commissioning please refrain from carrying out any manipulations that could
jeopardize your warranty rights.
Warning signs
CAU ION!
This symbol in combination with the signal word
indicates that damage to assets or data loss will
occur if suitable precautions are not taken.
Note signs
IP!
This symbol refers to important information about
the product or its handling or additional use.
REFERENCE!
This symbol refers to Further information in other
sections chapters or manuals.

1.2 Description
The head transmitter WTX700 designed for industrial applications consists of the
transmitter with integrated transmission unit and an antenna-battery case. The
transmitter is designed for integration into the connection head. Integration into
customer-specific connection heads is also possible. The antenna-battery case is
installed on the connection head via a thread (M20 x 1.5).
The measured value is transmitted wireless by the receiver (WRX900) displayed
on the LCD display and provided on the receiver via the RS485 interface as well as
an analog output. The radio frequency within the ISM band (Industrial Scientific
and Medical Band) is 868.4 MHz. This frequency is almost insensitive to external
interferences and allows transmission even in a rough industrial environment.
When using the antenna wall holder with the 10 meter long cable for the receiver
the maximum open air range is 300 m.
A lithium battery 3.6 V 2.2 Ah (size AA) is used for the transmitter power supply.
Transmitter (probe) and receiver can be configured with the optional setup
program (probe ID transmission interval measuring range and if necessary
probe type). The configuration data can be archived and printed. Changed
parameters can be overwritten again with the factory settings at any time. The
connection between transmitter and PC is established via a PC interface
(USB/TTL).
Configuration can be preset if stated at time of order.

2 Identifying the instrument version
2.1 Probe ID
Position
The factory set probe ID is stated on a sign fitted on top of the transmitter.
Probe ID
The probe ID is factory set. It must be entered and activated on the receiver to
establish communication between the probe and receiver. The probe ID can be
changed to customer specific requirements using the setup program. The user
must ensure that probes with identical probe IDs are not used together.

3 Probe preparation
3.1 Fitting/exchanging the battery
CAU ION!
Ensure that soiling moisture and vapors cannot enter the
device. The device could be destroyed. When
inserting/changing the lithium battery ensure that the
device is not exposed to soiling moisture and vapors.
CAU ION!
The probe does not function if the poles are incorrectly
connected. The battery and the probe electronics could be
damaged. Ensure that the poles are correctly connected.
CAU ION!
Incorrect batteries put safety at risk. The device could be
destroyed when using incorrect batteries. Only use the
lithium battery available as accessories.
Power supply of the probe is provided by the included 3.6 V 2.2 Ah lithium
battery inserted in the antenna-battery case ready for use. Battery service life
depends on the set transmission interval and the ambient temperature: approx. 1
year with the factory-set values (transmission interval 15 s) and room
temperature.

If the battery was removed or must be replaced proceed as follows:
Step Activity
1 Undo the battery lid screw (A) on the antenna-battery case and
open the case lid (B).
2 Press on the battery in the area of the minus pole (D) to remove the
battery (C).
3 When inserting a battery always insert the minus pole (D) side first
followed by the plus pole (E).
4 Close the case lid (B) again and ensure the correct seal position.
5 Retighten the battery lid screw (A).

3.2 Battery service life
The battery service life depending on the transmission interval (2 s 15 s 30 s 90
s) and the ambient temperature are shown in the following figure.
3.3 Disposal of lithium batteries
Please dispose of all batteries according to the national regulations. Insulate the
contacts of lithium batteries not completely discharged. Disposal of batteries
together with domestic waste is expressively prohibited. Batteries can be
deposited at communal waste collection points or the local retailers.

5 Installation
5.1 Information about fastening, securing and arrangement
IP!
Install the antenna-battery case vertically to the
top and if possible with free view to the receiver
antenna.
IP!
Never cover or coat the antenna-battery case with
metallic objects. Otherwise the probe range is
impaired.
IP!
For optimum probe function ensure a minimum
spacing of 200 mm between the probes.
