Critical Precautions
-
ESD Protection: Always wear a grounded wrist strap.
-
Extreme High-Voltage/Current Hazard: Relay outputs switch 115VAC/15A—lethal. Use proper insulation.
-
Relay Inductive Derating: For inductive motors, derate from 15A to 11A.
-
SS Polarity: Solid-state outputs are DC-only and polarity-sensitive.
-
SS Overcurrent: If output exceeds 6.5A, LED flashes red.
-
RTD Wiring: Use 3-wire Pt100 RTDs.
-
AI Model Learning: Requires 120-hour initial learning.
-
Fan Health Baseline: 14-day baseline required.
-
Quad-Redundant Paths: All four paths must be connected for full fault tolerance.
-
CPU Compatibility: Requires Mark V CPU firmware v10.0 or higher.
-
Power Supply: Draws 8.5A on +5V rail—power supply upgrade is mandatory.
