OUTPUT CIRCUIT DIAGRAMS
Note: 1. For E3A2-XCM4 amplifier with-
out built-in timer functions,
operation follows the NORM
mode shown with multi-function
time delay model.
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 ON-
and 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.
