The temperature switch TRS 5-50 is used in conjunction withtemperature sensor TRG 5-6.. as safety temperature limiter ormonitor, for instance in steam boilers and (pressurised) hotwater plants. When the max. admissible temperature in thesuperheater or the inlet line is reached, the safety temperaturelimiter or monitor switches the heating off.The temperature switch TRS 5-52 is designed for use inconjunction with temperature sensors TRG 5-63, TRG 5-64,TRG 5-65, TRG 5-66, TRG 5-67 and TRG 5-68.FunctionA platinum resistance thermometer Pt 100 to EN 60751 isused as temperature sensor for the temperature switch TRS5-50. A three-wire configuration is used for the electricalconnection.The temperature switch processes the temperature-dependent changes in resistance of the temperature sensor and,during normal operation, the seven-segment LED displayshows the adjusted switch-off temperature TMAX (°C) andthe actual value T (°C).The switchpoint for MAX temperature can be variably adjustedwithin the measuring range. Once the MAX temperature isreached both output contacts of the temperature switchopen the safety circuit and the seven-segment LED displayfor TMAX is flashing.In addition the relay contact for external signalling equipmentis closed.If the system is configured as safety temperature monitor,the temperature switch does not automatically interlock thedeactivation of the heating. As soon as the temperature hasfallen below the non-adjustable hysteresis, the safety circuitwill be closed again.However, if the system is configured as safety temperaturelimiter, the temperature switch automatically interlocks thedeactivation of the heating. Note that once the temperaturehas fallen below the non-adjusted hysteresis, the equipmentmust be reset manually or externally in order to close thesafety circuit.Any error or malfunction that occurs in the temperaturesensor, the electrical connection or the temperature switch isindicated by the seven-segment LED display and the outputcontacts will be opened.An automatic self-testing routine monitors the safety functions in the temperature switch and the temperature sensor.In the event of a malfunction the safety circuit opens instantaneously and switches the heating off.Parameter settings can be changed, a MAX temperaturealarm can be simulated and the equipment can be reset byoperating the rotary button.For external temperature indication the equipment is optionally available with an actual-value output 4-20 mA.
