If desired, a second input may be used to monitor the internal IRSM ambient temperature. Consult ANAFAZE formore information.3.3.11 SCALING AND CALIBRATIONThe ANAFAZE <strong>12LS</strong> includes a scaling provision to convert analog inputs into engineering units. Section 4.5.2.3describes how to set the automatic scaling.3.3.12 DIAGRAMS OF TYPICAL INPUTSCH # +IN O--- White ---------------------------IN COM O--- Red ---------------------------Earth GND O-- T/C Wire Shield if used------CH # +IN O--- Yellow --------------------------IN COM O--- Red ---------------------------Earth GND O-- T/C Wire Shield if used------CH # +IN O-------------------------------------IN COM O------------------------------------Earth GND O-- Shielded wiring recommended-----Type J T/CUNGROUNDEDType K T/CUNGROUNDED4-20mAdc/Voltage3.4 CONTROL OUTPUTS+-----------------------------------------------------+¦ WARNING! -- GROUND LOOP POTENTIAL ¦+-----------------------------------------------------¦¦ The ground of every control output is connected to ¦¦the ANAFAZE <strong>12LS</strong> logic ground.

These are provided on the 50 pin ribboncable connector <strong>and</strong> are set for heat/cool whether or not they will be used for each application.1. Each output may be individually programmed as a different type (on/off, CTP, or DZC.).2. Each output can be individually programmed to be direct or reverse acting [both outputs can be the same].3. There may be a deadb<strong>and</strong> programmed for heat/cool, <strong>and</strong> within that deadb<strong>and</strong> both outputs will be off.3-14
