NOTICE: The information contained in this document is subject to change without notice. Please read these Operating Instructions before commissioning the instrument. -
Page 4: Area Of Use
1.6 Area of use nVent RAYCHEM NGC-40-SLIM limiters are used for temperature limiting of electrical heaters in industrial and potentially explosive atmospheres. The NGC-40-SLIM is a safety temperature limiter. NGC-40-SLIM units are approved for use in non-hazardous areas. Where needed the temperature sensor of the unit can be placed in Zone 1, Zone 2, Zone 21 and Zone 22 when the sensor is hazardous area approved. -

NGC-40-SLIM units can be reset by means of a Trip Reset push button, an external hardwired signal or via dedicated software. The output of the unit will only be enabled when all conditions are safe; meaning that the temperature measured by the limiter RTD has dropped below the limiter set point and when there are no other faults being detected. -
Page 14: Reset Safety Temperature Limiter
Refer to section 3.7 below for the procedure to change the safety limiter set point. The safety temperature limiter operates totally independent of the temperature control system and has its own temperature inputs (RTD Limiter). In case of a defect to any part of the NGC-40-SLIM unit the device shall be de-energized before replacing the defective equipment. -

3.9 Safety related system characteristics The failure types of; sensor break, sensor short, sensor misconnected and random hardware failure are permanently monitored. IMPORTANT NOTICE In case a failure of the safety system is detected either during operation or during routine maintenance when executing a function test the unit should be switched off and taken out of service. - Page 16 Europe, Middle East, Africa Lietuva/Latvija/Eesti Suomi +32 16 213 511 +370 5 2136633 Puh. 0800 11 67 99 Fax +32 16 213 603 Fax +370 5 2330084 salesfi@nVent.com thermal.info@nVent.com info.baltic@nVent.com Sverige België / Belgique Magyarország +46 31 335 58 00 +32 16 21 35 02 +36 1 253 4617 salesse@nVent.com...
