Add a snubber or diode across the load. | | Buttons unresponsive | Lock mode enabled (if featured) | Power cycle device. Press and hold START + SET for 5 seconds. | | Display shows "Err" or "----" | Invalid time setting (e.g., T1=0 with T2>0) | Re-enter programming and set T1 to at least 1 unit. | | Trigger doesn’t start timer | Wrong signal level (3.3V vs 5V/12V) | Apply >70% of supply voltage to IN pin. |
