Universal Temperature Converter KCD2-UT2-(Ex)1 Overview The temperature converters KCD2- UT2-(Ex)1 of the K-System (referred to as UT2) are used for temperature measurement. Resistance temperature detectors, thermocouples, potentiometers or voltage sources can be connected to the inputs of the converter. The device converts the input signals into proportional current signals or voltage signals. -
Page 6: Safety Instructions
If malfunctions cannot be eliminated, place the devices out of service and protect them from accidental use. The devices may only be repaired directly by the manufacturer Pepperl+Fuchs. Any opening or change in the units are dangerous and are therefore not to be performed. They void any warranty. -
Page 7: Explosion Protection
For secondary explosion protection, that is, measures to avoid the ignition of a surrounding explosive atmosphere by electrical MANUAL equipment, Pepperl+Fuchs will gladly provide you with a copy of the EXPLOSION PROTECTION "Ex-protection manual" for a nominal fee. Please pay particular attention to EN 60079-0, EN 60079-11 and EN 60079-15 or the corresponding national provisions. -
