2 Basic safety instructions
2.1 Designated use
The Thermophant T is a temperature switch for monitoring, displaying and regulating process
temperatures. The device has been safely built with state-of-the-art technology and meets the
applicable requirements and EC Directives. It can, however, be a source of danger if used
incorrectly or for anything other than the designated use.
2.2 Installation, commissioning and operation
Installation, electrical connection, commissioning, operation and maintenance of the measuring
system must be carried out by trained, qualified specialists authorised to perform such work by
the facility's owner-operator. The specialist must have read and understood these Operating
Instructions and must follow the instructions they contain. The device may only be modified and
repair work carried out if this is explicitly permitted in the Operating Instructions. Damaged
devices which could be a source of danger may not be commissioned and must be labelled and
identified as defective.
2.3 Operational safety
The measuring device meets the general safety requirements according to EN 61010-1 and the
EMC requirements according to IEC/EN 61326 in addition to the NAMUR recommendations NE
21, NE 43 and NE 53.
• Functional safety
The Thermophant T temperature switches were developed according to the standards IEC
61508 and IEC 61511-1 (FDIS). The device version with PNP switch output and additional
analog output is equipped with fault detection and fault prevention facilities within the
electronics and software.
•Ex-area
The Thermophant T is not approved for use in Ex-areas.

In the event of a fault in a sealing ring (O-ring) or seal, the following measures must be taken:
• Remove the thermometer, clean the thread and the O-ring groove
• Replace the sealing ring or seal
• Perform CIP following installation
In the case of weld-in connections, exercise the necessary degree of care when carrying out
welding work on the process side:
• Suitable welding material
• Flush-welded or with welding radius > 3.2 mm (0.13 in)
• No recesses, folds or gaps
• Honed and polished surface, Ra ≤0.76 μm (0.03 μin)

7.1.5 Settings for output - 2x switch output
• Hysteresis function
The hysteresis function enables two-point control via a hysteresis. Depending on the
temperature T, the hysteresis can be set via the switch point SP and the switch-back point
RSP.
• Window function
The window function enables the monitoring of a process temperature range.
• NO contact or NC contact
This switch function is freely selectable.
• Delay times for switch point SP and switch-back point can be set in increments of 1 s. By this
means undesirable temperature peaks of short duration or of high frequency can be filtered
out.
• Factory setting (if no customer-specific settings have been ordered): Switch point SP 1: 45 °C
(113.0 °F); Switch-back point RSP 1: 44.5 °C (112.1 °F) Switch point SP 2: 55 °C (131.0 °F);
Switch-back point RSP 2: 54.5 °C (130.1 °F)
