For E3A2-XCM4 amplifier without built-in timer functions, operation follows the NORM mode shown with multi-function time delay model. Incident Interrupted NORM ON OFF ON-D. ON OFF OFF-D. ON OFF O.S.D. ON OFF T T T LIGHTON Multifunction (-T) T T T T T T T ON/OFF-D. ON OFF NORM ON OFF ON-D. ON OFF OFF-D. ON OFF O.S.D. ON OFF T T T Output mode (No output) DARK ON T T T T T T ON/OFF-D. ON OFF T1 LIGHT-ON ON OFF DARK-ON ON OFF ON+OFFdelay (-D) T2 T1 T2 T1 T2 4 4 T2 T1 2. T1, T2 and T denote set time, variable within 0.1 to 5 second range. 3. For multi-function time delay model (E3A2-XCM4T), the ONand OFF-delay time settings will be the same for T1 and T2. 4. For ON- and OFF-delay model (E3A2-XCM4D), T1 and T2 are independently variable.
