The Paragon EL7200/208‑240 is a dual‑channel programmable electronic time controller designed for industrial or commercial lighting, HVAC, motors, and pumps on 208–240 V AC. Common failures include power supply module burnout (visible brownout or blown fuses), relay contact wear or arcing leading to intermittent or stuck outputs, and internal PCB component degradation such as electrolytic capacitors or ICs that can cause the unit to freeze or display error codes. First‑check diagnostics: verify input voltage and fuse integrity; inspect the relay contacts for corrosion or pitting; test the power supply rails with a multimeter; review any displayed fault codes against the user manual; and perform a visual inspection of the PCB for burnt components or loose connections.[oss-gpt-20b]
