3. Mounting / General information

Capillary / temperature probe / pocket

General information

■

If the capillary of the surface-mounting thermostat is cut through or becomes

kinked, this could result in permanent device failure!

■

The minimum bending radius allowed for the capillary is 5 mm.

■

JUMO pockets must be used when installing the temperature probe, if the approval

for the surface-mounting thermostat is to remain valid.

■

The temperature probe must be fully immersed in the measurement medium.

■

When air is the measurement medium, you must choose a process connection

without a pocket.

■

To ensure the general accuracy of the operating value, the instruments must only

be used with the pockets supplied on delivery (diameter D = 8, 10 mm).

■

Only a probe of diameter d = 8 mm may be used in pockets of D = 10 mm.

■

Multiple assignments of pockets are only allowed with 2 or 3 cylindrical probes of

Ø 6 mm and pockets of 15 x 0.75 mm.

■

If two probes are assigned, the spring clip provided on delivery must be installed in

the pocket.

■

With pockets 22, 32, 41, 42 and 45 made from St 35.8I/16Mo 3 materials, the

allowed operating period at operating temperatures above 420°C is limited to
200,000 hours. Compliance with TRD 508 is essential for applications in this range.

5. Installation

Regulations and notes

■

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

V

■

The choice of cable, the installation and the electrical connection must

conform to the requirements of VDE 0100 “Regulations on the Installation of
Power Circuits with Nominal Voltages below 1000 V” and the appropriate
local regulations.

■

If contact with live parts is possible when working on the device, it must be

completely disconnected from the electrical supply.

■

Ground the instrument to the protective earth at the PE terminal. The cross-

section of this cable must be at least the same as that of the supply cables.
Wire the grounding conductors in a star configuration to a common earth
point that is connected to the PE conductor of the electrical supply. Do not
loop the grounding cables, that is, do not run them from one instrument to
another.

■

Apart from faulty installation, incorrect settings on the thermostat may also

adversely affect the proper functioning of the subsequent process or cause
other damage. It should only be possible for qualified personnel to make
these settings. Please observe the relevant safety regulations for such
matters.

Resetting the STB

Once the temperature has fallen below the set limit (safe temperature limit) by about
10% of the scale range, the microswitch can be reset.

1.

Open the housing

2.

Press the reset button
until the microswitch is
reset.

Self-monitoring

Response to a fracture of the measuring system

With the STB and STW (STB), a fracture of the measuring system (leaking)
causes the circuit to stay open permanently. With the STB, the microswitch is

also locked.

Response to low temperature

Using the STW (STB) as an STB

V

With the STW (STB) and STB, if the probe temperature falls below the
minimum value of -20°C, the circuit opens. Once the probe temperature has
risen above the minimum value, the STB must be reset manually .

With the STW, reset is automatic.

The required lock-out facility must be ensured by the subsequent circuit. This
circuit must comply with VDE 0116.
