1.3 Description

The highly precise, electronic temperature switch comprises a sheath with built-in temperature
probe, a process connection as well as an attached case with LCD display for the electronics.
Depending on the application, the following output variants are available: 1x PNP or 2x PNP
switching output (binary output) or 1x PNP switching output and 1x analog output.

The configuration of the output signal and the measuring range can be customized.
Depending on the version, the electronic temperature switch can be used in an operating tem-

perature range from -50 to +150 °C, -50 to +260 °C and -50 to +500 °C. The analog output sig­nal 4 to 20 mA, 0 to 20 mA, 0 to 10 V or reversed 20 to 4 mA, 20 to 0 mA and 10 to 0 V is
available linearized (temperature linear).

The electronic temperature probe is designed for industrial applications and complies with the
European Standards to guarantee electromagnetic compatibility (EMC).

3.1 Installation notes

CAUTION!

The electrical connection must only be carried out by qualified personnel!

• Ensure that the fuses of the load circuits are suitable for the maximum loads to avoid dam­age to the device.

• The electromagnetic compatibility meets standard EN 61326.

• Do not connect any additional consumers to the voltage supply of the device.

• The device is not suitable for use in areas with an explosion hazard (Ex areas).

• In addition to a faulty installation, also incorrectly set values on the device could impair the
orderly function of the following process or lead to damage. For this reason, always provide
safety devices/guards independent of the device, the setting of which is restricted to expert
personnel.

6.9 Setting the output signal scaling

The output signal scaling describes how the measured temperature is "converted" to an output
signal.

Simple example:
Actual

The device has a measuring range (1) from -50 to +150 °C and the output signal 4 to 20 mA
(3).

Set point

The customer wants that the "Customer measuring range“ (2) -50 to +150 °C (100 % from the
measuring range (1)) complies with the 4 to 20 mA (100 %) output signal (3).

(1) Measuring range (2) Customer specific measuring range

(3) Output signal

48

Customer specific scaling

It is frequently desired that a part of the measuring range is scaled to the output signal.

Example:
Actual

The device has a measuring range (1) from -50 to +150 °C and the output signal 4 to 20 mA
(3).

Set point

The customer wants that the "Customer scaling range“ (2) 0 to 50 °C (25 % from the measuring
range (1)) complies with the 4 to 20 mA (100 %) output signal.

Scaling is 1 : 4 (25 % : 100 %).

Inverting the output signal

The device offers the possibility to invert the output signal (3).
During this process the output signal

• 0 to 20 mA is inverted to the output signal 20 to 0 mA

• 4 to 20 mA is inverted to the output signal 20 to 4 mA

• 0 to 10 V is inverted to the output signal 10 to 0 V

6.9.1 Setting the scaling start value (Sc.Lo)

TIP!

The output signal can only be scaled on devices with analog output.

Setting range: Measuring range

Factory-setting: Measuring range start

Example:

The device has a measuring range from -50 to +150 °C.
The device output signal is 0 to 20 mA.

Objective: The range from 0 to 100 °C (customer scaling) is to be displayed on the out-

put side by 0to20mA.

Setting: Scaling start value (Sc.Lo) = 0

Scaling end value (Sc.Hi) = 100

Result: At a temperature below 0 °C, the device indicates an error (measuring

range gone below) and provides the respective error signal (0 mA) on the
analog output.

At a temperature of 0 °C, the device provides 0 mA on the analog output.

At a temperature of 100 °C, the device provides 20 mA on the analog out­put.

At a temperature exceeding 100 °C, the device indicates an error (measur­ing range exceeded) and provides the respective error signal (22 mA) on
the analog output.
