1. Safety instructions

When mounting, initiating and operating these transmitters

it is important to observe the respective national safety

precautions and regulations in eect (e.g. VDE 100).

Nonobservance of the applicable regulations may cause

severe injury to persons or damage to equipment. Only sta

with suitable qualication should work with these transmitters.

Before initial operation check the suitability for the intended application.

In particular, it is important to fulll the ambient and operation conditions

as specied in the WIKA data sheet TE 19.03. Use only congured

transmitters.

2. Before mounting

2.1 Transmitters with standard measuring ranges

Series T19 transmitters with standard measuring ranges are congurable

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 congured.

To work properly, the transmitter has to be congured. Make

sure that the transmitter is congured before mounting.

Conguration is to be carried out as described in section 3.

As an option standard measuring ranges can be congured at the factory

and in this case the appropriate measuring range is printed on the rating

plate. Transmitters with standard measuring range congured 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

recongured. Special measuring ranges can be recognised by a 9 as last

digit in the model designation: T19.x0-xx0-9

Special measuring ranges are congured at the factory and can be

immediately tted at the measuring point and put into operation.

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: Snapt the bottom to the case again

Model T19.30: Snapt 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 ax in the connecting head using screws in pressure springs.

WIKA Operating Instructions Temperature Transmitter T19

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 axed 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.!

6. Maintenance

The temperature transmitters described here are maintenance-free!

The electronics incorporate no components which could be repaired or

replaced. Depending upon operating conditions, it may be advisable to

check the adjustment yearly. Adjustment as per section 7.

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.
