MODE
MODE tri-state input operation mode selection. following table Override Control (for PT8A2621 only): term "override" refers change operating mode switching power switch twice within seconds. When chip working AUTO mode (MODE openned), output activated valid trigger signal output active duration controlled OSCD oscillation period. lamp switched from AUTO mode either switching MODE switching power switch twice within Table Operation Modes MODE MODE Status Open Operation Mode AUTO

Note:Flash only TRIAC Rev. used reset device. internal pull-high active low. CRST extend power-on initial time. openned (without CRST), initial time seconds. Figure
Description Output always RELAY sends high level relay driving; TRIAC pulse train output synchronized triac driving. Output always OFF: RELAY sends level relay driving; TRIAC sends high level triac driving. Outputs remain state until activated valid trigger input signal. When working AUTO mode, device allows override control switching signal.
