1 Introduction
1.2 Application
Surface-mounting thermostats Series ATH.-SE-.. are approved for monitoring
installations on steel-hulled ocean-going ships (e.g. steam and boiler plant,
indirect heating systems) as:
❏ Temperature monitor (TW)
❏ Safety temperature monitor STW (STB)
❏ Safety temperature limiter (STB).
The versions comply with DIN EN 14597 and are approved as per the guidelines of the Classification Societies:
- Germanischer Lloyd
- Det Norske Veritas
- Bureau Veritas
- Pressure Equipment Directive 97/23/EC CE0036
(ATH.-SE-20 and ATH.-SE-70 only)
Cutting through or kinking the capillary of the surface-mounting thermostats
A
Type ATH.-SE-.. will lead to permanent failure of the instrument!
1.3 Marking
H
Surface-mounting thermostats Type ATH.-SE-.. are approved as per DIN EN 607302-9.
1.4 Safety notes
In the event of a measuring system breakage, the filling liquid can escape.
H
There is currently no statement by the health authority concerning hazards to
health in the event of short-term exposure and low concentration, e.g. in the
event of a measuring system break.

3.4 Capillary / temperature probe / sheath
3.4.1 General
Cutting through or kinking the capillary will lead to permanent failure of the
A
H
instrument!
Minimum permissible bending radius of the capillary is 5 mm.
The temperature probe must be fitted in a JUMO sheath, otherwise the
approval of the surface-mounting thermostat becomes invalid.
The temperature probe must be completely submerged in the medium.
In order to ensure the general accuracy of response, the instruments must only
be used with the sheaths supplied from the factory (diameter D = 8, 10 mm).
Only probes with a diameter d = 8 mm may be fitted in sheaths with a diameter
D = 10 mm.
When the operating medium is air, connection type "10" (without sheath) must
be selected.

The plain cylindrical probe, Form 10 must only be used in pressureless
medium.
Due to the general accuracy of response, the instrument must only be used
with the factory-supplied sheaths.
3.6 Mounting the probe
( 1 )
( 2 )
Submerge the sheath and the temperature probe (2) into the medium and
H
ensure that the temperature probe (2) is completely submerged in the medium
because otherwise, greater switching point deviations will occur.
For thermostats with longdistance line (abbreviation
"f"), the temperature probe
is fastened in the sheath by
means of the clamping
piece (1) for connection
types "20".

4.1 Regulations and notes
4 Installation
V
❏ The electrical connection must only be made by qualified personnel.
❏ The choice of cable, the installation and the electrical connection must
conform to the requirements of VDE 0100 “Regulations for the installation
of power circuits with nominal voltages below 1000 V”, or the appropriate
local regulations.
❏ If contact with live parts is possible while working on the unit, it must be
completely disconnected from the supply.
❏ Earth the instrument at the PE terminal to the protective conductor. This
cable must have a cross-section that is at least as large as the supply
cables. Earth cables must be run in a star configuration to a common earth
point which is connected to the protective earth of the supply. Do not loop
earth cables, i.e. do not run them from one instrument to another.
❏ Apart from faulty installation, incorrect settings on the thermostat can affect
the proper functioning of the following process or lead to damage. Setting
up must therefore be restricted to qualified personnel. Please observe the
appropriate safety regulations in this respect.

( 5 )
✱ Open the case.
➈ Section 3.2 “Opening the case”, page 10.
✱ Pass the connection cable (cable diameter 10 — 16,5 mm) through the
screw connection (3). Fitting type"X" (no special tools), screw connection
up to 2.5 mm
✱ Remove the protective cover ( 4 ).
✱ Establish the connection to the terminals ( 1 ) in accordance with the appro-
priate connection diagram.
✱ Connect the protective conductor to terminal PE ( 2 ).
✱ Refit the protective cover ( 4 ) and snap it onto the guide lug ( 5 ).

4.2.1 Closing the case
✱ Make sure that the plastic gasket in the lower part of the case ( 2 ) is seated
correctly.
On thermostats with code -70, the external reset button ( 3 ) must be located
H
precisely on top of the internal reset button ( 4 ) for the microswitch, since this
is the only way the reset button ( 3 ) can be operated from the outside.
✱ Place the upper part of the case ( 1 ) onto the lower part ( 2 ).

Cable relief ✱ Turn the screw connection ( 1 ) clockwise until the cable inlet is sealed and
the cable is secured against pulling out. The cable has to be protected
against vibration overload by leaving sufficient extra cable length ( 2 ).

5.3.2 Response to low temperature
H
a measuring system breakage (leakage).
On the STB, the microswitch is additionally locked.
If the probe temperature goes below the minimum value of -10 °C, the circuit is
opened.
After the minimum probe temperature is exceeded, the STB must be manually
reset.
➈ Section 5.2 “Resetting the STB”, page 19.
The TW and STW reset automatically.
5.4 Using the STW(STB) as STB
V
The restart lock as per DIN EN 14597 must be ensured by the subsequent circuit. This circuit must be in accordance with VDE 0116.
