  1. Power the unit correctly: The TM-630S uses a wide voltage input (check your label: usually AC/DC 12-240V). Connect Line (L) and Neutral (N) to the designated power terminals. Reverse polarity on DC models will fry the unit.
  2. Relay contact rating: The internal relay is typically rated for 10A at 250V AC. Do not exceed this. For motors or pumps, derate to 5A.
  3. Trigger signal: In modes like F-2 or F-5, the trigger requires a "dry contact" (simple switch) or an active low voltage (check manual for your exact version).
  4. Memory loss: If the display flashes F--E, the unit has lost its memory due to power interruption during setup. Reprogram it from scratch.
