Pin 1 connect to VDD (+) = Retriggerable
Pin 1 connect to VSS (-) = Non-Retriggerable
Pin 1 connect to VDD (+) = Retriggerable
Pin 1 connect to VSS (-) = Non-Retriggerable

Tx is LED On timer. Factory default is 6.6 second. Tx = 24,576 x R20 (Ω) x C7 (F) = 24,576 x 15,000 x 18 nF x 10-9 = 6.6 second
Ti is inhibit movement after LED Off timer. Factory default is 4.8 second. Ti = 24 x R8 (Ω) x C8 (F) = 24 x 2,000,000 x 100 nF x 10-9 = 4.8 secondModified
This item connect Pin 1 to V+ So it already config as retriggerable.
Next modified R20 to 407K.
Tx = 24,576 x R20 (Ω) x C7 (F) = 24,576 x 475,000 x 18 nF x 10-9 = 210 secondNext modified R8 to 2M + 100K in parallel.
Ti = 24 x R8 (Ω) x C8 (F) = 27 x 95,238 x 100 nF x 10-9 = 0.25 second
