3.6 Step-by-Step Installation Instructions

1. Insert P0914XL vertically into the slot of P0914 series dedicated backplane inside 19-inch control cabinet;

2. Connect 24VDC regulated power supply and confirm positive/negative polarity correctly;

3. Wire thermocouple probes to matched terminal assembly (TA), distinguish positive and negative thermocouple wires strictly;

4. Lock all wiring terminals to prevent loose contact and signal drift;

5. Power on the cabinet, open I/A Series configuration software to select corresponding thermocouple type for each channel;

6. Check LED indicators: steady green = normal collection, flashing red = channel open/short-circuit fault.
