WARNINGUse of the grounded T/C, meaning that the T/C junction is at the same potential of the metal protection sheath of theT/C assembly, may cause calibration shifts <strong>and</strong>/or erratic temperature readings of the input. The use of a grounded T/Cin a process using electrical energy for heating, may also cause damage to the <strong>12LS</strong>.The ungrounded T/C, meaning that the T/C junction is electrically isolated from the metal sheath of the T/C assemblyis recommended by ANAFAZE for use as the type of T/C to be use with the <strong>12LS</strong>.When updating an existing temperature control system with the ANAFAZE <strong>12LS</strong>, it is highly recommended that allgrounded T/C in use with the old system be changed to ungrounded types of T/C.3.3.9RTD INPUTSRTD's should have external signal conditioning with an isolated 4-20ma output or the equivalent for connection to the<strong>12LS</strong>. Please consult ANAFAZE for additional information.3.3.10 INFRARED NON-CONTACT TEMPERATURE SENSORSThe ANAFAZE IRSM (infrared sensing module) is ideally suited for many infrared non-contact temperatureapplications. It can be supplied by ANAFAZE as a fully integrated system with the <strong>12LS</strong> configured to providepower for up to four IRSM modules <strong>and</strong> for direct connection of the IRSM output. The following connections arerequired if the IRSM internal ambient sensor is not used:+--------------------------------------------------------------+¦ TABLE 3-2.
