6 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 and are approved as per the guidelines of the Classification Societies: - DNV GL - Bureau Veritas - Pressure Equipment Directive CE0036 (ATH.-SE-20 and ATH.-SE-70 only) A Cutting through or kinking the capillary of the surface-mounting thermostats 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 Safety notes H In the event of a measuring system breakage, the filling liquid can escape. 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.

10 3 Mounting 3.2 Opening the case Opening Unscrew the two lead-sealable cheese-head screws ( 5 ) Remove the upper part of the case ( 1 ) ( 5 ) ( 5 ) ( 1 ) V Ensure that the gasket is seated correctly when reassembling! 3.3 Fixing the surface-mounting thermostat Operating position unrestricted (for open-air mounting on request) Code s (rigid stem) The case journal is secured in the enlarged open end of the sheath by two fixing screws Code f (with capillary) by ½" pipe thread on the case journal 10

11 3 Mounting 3.4 Capillary / temperature probe / sheath General A Cutting through or kinking the capillary will lead to permanent failure of the 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. H 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 Approved process connections Temperature probe 10 Sheaths 20, 30 H refer todata sheet ! 11

12 l 3 Mounting 3.5 Permissible pressure at the sheath Sheaths 20 and 30 A The following values refer to the maximum pressure of the probe mounting concerned. The maximum pressure which can be sealed depends on the mounting conditions and may possibly be lower Stainless steel sheath Material Tube and nipple material: X 6 CrNiMoTl Temperature Tube diameter 8 x 0.75 mm or conical 10 x 0.75 mm Max. permissible pressure Max. permissible pressure 100 C 92bar 74bar 150 C 88bar 71bar 200 C 83bar 67bar 300 C 72bar 58bar Permitted flow velocities on request Sheath "20" made of brass Sheath "20" tube and nipple material: brass Temperature Tube diameter 8 x 0.75 mm 10 x 0.75 mm Max. permissible pressure Max. permissible pressure 100 C 50 bar 40 bar 150 C 48 bar 39 bar Emitted flow velocities H A on request 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. 12

13 3.6 Mounting the probe H 3 Mounting Submerge the sheath and the temperature probe (2) into the medium and 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". ( 1 ) ( 2 ) 13

14 4.1 Regulations and notes V 4 Installation 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. 14

15 4 Installation 4.2 Electrical connection 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 2 conductor cross-section. Establish the connection to the terminals ( 1 ) in accordance with the appropriate connection diagram. Connect the protective conductor to terminal PE ( 2 ). 15

16 4 Installation Connection diagrams TW / STW (STB) Closing the case STB as N/C contact with signal contact STB with (N/C) break contact Make sure that the plastic gasket in the lower part of the case ( 2 ) is seated correctly. H On thermostats with code -70, the external reset button ( 3 ) must be located 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 ). ( 3 ) ( 1 ) ( 2 ) H ( 5 ) ( 4 ) ( 5 ) Tighten the lead-sealable cheese-head screws ( 5 ). 16

17 4 Installation 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 ). Close the case. 17

18 5 Settings 5.1 Setting the limit value Open the case. ➈ Section 3.2 Opening the case, page 10. Set the limit value on the set point setter ( 5 ) using a screwdriver. (1) Top stop ( 2 ) Bottom stop ( 3 ) Set point indicator ( 4 ) Scale division ( 5 ) Set point setter 18

19 5 Settings 5.2 Resetting the STB After the temperature has fallen below the set limit value (safe temperature limit) by about 10% of the scale range, the microswitch can be reset. Action Unscrew the cap nut (1). Press the reset button (2) until the micro switch is reset. Screw the cap nut (1) back on 5.3 Self-monitoring Behaviour in the event of a measuring system breakage H On the STB and STW (STB), the circuit stays open permanently in the event of a measuring system breakage (leakage). On the STB, the microswitch is additionally locked Response to low temperature H The electrical circuit opens when cooling the probe of STW (STB) and STB down to the negative temperature range, but it then closes again if the temperature rises. The STB must be unlocked manually if the minimum probe temperature is exceeded. The STW (STB) unlocks itself automatically. 5.4 Using the STW(STB) as STB V The restart lock as per DIN EN must be ensured by the subsequent circuit. This circuit must be in accordance with VDE
