1. Safety instructions
When mounting, initiating and operating these transmitters
it is important to observe the respective national safety
precautions and regulations in eect (e.g. VDE 100).
Nonobservance of the applicable regulations may cause
severe injury to persons or damage to equipment. Only sta
with suitable qualication should work with these transmitters.
Before initial operation check the suitability for the intended application.
In particular, it is important to fulll the ambient and operation conditions
as specied in the WIKA data sheet TE 19.03. Use only congured
transmitters.
2. Before mounting
2.1 Transmitters with standard measuring ranges
Series T19 transmitters with standard measuring ranges are congurable
by means of solder bridges. Access to the solder bridges is gained after
removing the bottom of the casing. Mounted transmitters have to be
dismantled rst before they can be congured.
To work properly, the transmitter has to be congured. Make
sure that the transmitter is congured before mounting.
Conguration is to be carried out as described in section 3.
As an option standard measuring ranges can be congured at the factory
and in this case the appropriate measuring range is printed on the rating
plate. Transmitters with standard measuring range congured at the
factory can be immediately tted at the measuring point and put into
operation.

2.2 Transmitters with special measuring ranges
Series T19 transmitters with special measuring ranges cannot be
recongured. Special measuring ranges can be recognised by a 9 as last
digit in the model designation: T19.x0-xx0-9
Special measuring ranges are congured at the factory and can be
immediately tted at the measuring point and put into operation.
3. Conguration
3.1 Working sequence
Model T19.10 head mounting:
Remove case bottom
Model T19.30 rail mounting:
Remove case lid
Set the solder bridges for the
desired measuring range in
accordance with tables 1 – 7. The
measuring ranges to be selected
depend on the model of the
transmitter.
Model T19.10: Snapt the bottom to the case again
Model T19.30: Snapt the lid to the case again. Insert lid with its long
side into the case, then press lid to the case until it locks into place
Adjust zero point and span by means of potentiometer as described
in section 7!
Note the measuring range on the rating plate (for example, with
waterproof bretip pen)

4. Mounting
4.1 Mounting for head mounting version
The transmitters for head mounting (Model T19.10) are designed to be
mounted on a measuring insert in a DIN connecting head with form B.
The connecting wires of the measuring insert must be approx. 50 mm
long and insulated.
Insert the measuring insert with the mounted transmitter in the protective
sheath and ax in the connecting head using screws in pressure springs.

4.2 Mounting for rail mounting version
The transmitters for rail mounting (Model T19.30) are designed for
mounting on a standard rail or for wall mounting.
■
Rail mounting
The transmitter is axed without the use of auxiliary parts by sliding
onto a 35 mm top hat rail (DIN EN 50022-35).
De-mounting is done by freeing the snap parts.
■
Wall mounting
Lever the snap parts outwards with a screwdriver until they lock into
place. Mount case to the wall by means of two screws.
5. Electrical connections
In the case of the transmitters described here there is an
internal galvanic connection between the sensor input and
analogue output.
No external conducting is to be made (for example, by
earthing) between the connected temperature sensor and
analogue output!
We recommend the use of crimped connector sleeves in the
case of exible leads.
For Model T19.30 the connection cable of a temperature
probe must be shielded and grounded.
To connect a Pt100 sensor in a 2-wire connecting circuit:
Set a jumper between the input terminals 2 and 3 in accordance with
section 5.1.!

7. Adjustment of transmitter
The adjustment of the zero point and the span is carried out with
potentiometers. In order to adjust the transmitter output to optimal values
please adjust to the desired value by turning the potentiometer in one
direction only.
Example
Adjust the potentiometer in a clockwise direction.
The potentiometer has to be turned clockwise (the output current gets
higher) until the signal shows the desired value.
If the potentiometer is turned too much (the output current is too high),
the potentiometer must be turned back again until a value below the
desired value is reached (output current is too low). Adjust the potentio-
meter in a clockwise direction again until the desired value is reached.
Repeat steps as necessary.
