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. T
1
, T
2
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 T
1
and T
2.
4. For ON- and OFF-delay model
(E3A2-XCM4D), T

are
independently variable.
