Programmable Temperature Converter Type ST Technical Conditions, Installation, and Connection These technical conditions are valid for the temperature converters type ST. They define the technical data, method of installation, ordering and verification, and other basic information. 1. Terminology 1.1 Temperature Converter ST Industrial programmable temperature converter type ST converts of output signal from temperature sensor to unified or agreed output electrical signal. All types of resistance and voltage sensors may be used as temperature sensor in this device, eventually, after agreement with the producer, they may have a different output. It is possible to reprogram the gauging range either with PC or with a communicating cable KX-1. It is also possible to change the type of used temperature sensor. 2. Generally 2.1 Usage and Fabrication of the Temperature Converter ST Temperature converters type ST are used for converting of output signal from temperature sensor to unified or agreed output electrical signal. Thanks to its possibility of easy resetting or inverting its gauging range, choosing of temperature sensor type either with PC or with a communicating cable KX-1 the converter is widely used in automated systems. The converter type ST is produced in a plastic box so that it could be assembled to a wall. 3.

Installation and Operation The ST converter is to be screwed to an appropriate place on a wall. The sensor is to be connected to the input clamp in the lower part of the terminal box. The output signal and transmitter plugging are to be connected to the control system or to the visual display unit with the wires according to the table n. 2. Plugging of the temperature transmitter according to the table n. 2 must be done only by a person authorized in terms of the regulation 718/2002 Z. z., while they must observe these technical conditions and other relevant norms and instructions. The connecting wires must be chosen according to the environment, possibility of electromagnetic interference, and technical conditions of the temperature transmitter. In case of using the manometers in conditions, when voltage surges may appear, the producer recommends to protect the manometers with surge barriers, for example PBM – MERET.
