General safety instructions

1 General safety instructions

For your own safety, follow these instructions concerning the mounting, start up, and opera-

tion of the thermostat:

−The thermostat is to be mounted, started up or operated only by trained and experienced

personnel familiar with the product.

According to these mounting and operating instructions, trained personnel refers to

individuals who are able to judge the work they are assigned to and recognize possible

dangers due to their specialized training, their knowledge and experience as well as

their knowledge of the applicable standards.

−Upon installation of the electric cables and connecting the device, observe the VDE

regulations as well as the regulations of your local power supplier. Make sure all

electrical connections are installed only by trained and experienced personnel.

To avoid damage to any equipment, the following also applies:

−Proper shipping and storage are assumed.

The device with a CE marking fullls the requirements of the Directives 2014/30/EU and

2014/30/EU, 2014/35/EU and 2011/65/EU.

The EU declarations of conformity are included in the Appendix of these instructions.

Design and principle of operation

2 Design and principle of oper-

ation

The thermostats are equipped with a

changeover contact. When the thermostat is

triggered, the connection between connec-

tions 1 and 2 are interrupted and the con-

nections 1 and 4 are connected (see Fig.5

on page14).

Safety temperature monitor (STM)

A snap-action switch in the STM is triggered

when the temperature at the temperature

sensor rises above the adjusted set point.

When the temperature falls below the set

point by approximately 8K, the switch re-

turns to its original position.

The contact opens or closes when the tem-

perature at the temperature sensor falls be-

low –20°C. It automatically closes or opens

again when the temperature at the tempera-

ture sensor rises above –20°C.

The STM is triggered when the capillary tube

breaks.

Temperature regulator (TR)

The snap-action switch is triggered when the

temperature at the temperature sensor rises

above the adjusted set point. When the tem-

perature falls below the set point by approxi-

mately 4K, the switch returns to its original

position.

Safety temperature limiter (STL)

The snap-action switch is triggered and

locked when the temperature at the tempera-

ture sensor rises above the adjusted set

point. When the temperature falls below the

set point by approximately 10%, the

snap-action switch can be unlocked manual-

ly.

The contact opens or closes when the tem-

perature at the temperature sensor falls be-

low –20°C. It automatically closes or opens

again when the temperature at the tempera-

ture sensor rises above –20°C.

The contact opens or closes when the system

fails. It is not possible to unlock the device.

2.1 Typetesting

The thermostats are tested by the German

Technical Inspectorate (TÜV) according to

DINEN14597.

Inuence of mean ambient

temperature based on the set point

A shift of the switching point arises when the ambient temperature at the

knob and at the capillary tube deviates from the calibration ambient tem-

perature of +22°C:

Higher ambient temperature g Lower switching point

Lower ambient temperature g Higher switching point

This inuence is minimized by temperature compensation.
