INTEGRATION
• The pulse input mode starts the operation by starting the sig-
nal input.
• When using the unit by starting it with the power on, short-
circuit the signal terminal (8-pin: Q to R, 11-pin: E to Y
and screw: to ).
96
• Each signal input such as signal, reset, stop and lock inputs is applied by short-circuiting its input terminal and common termi-
nal (8-pin type: terminal Q, 11-pin type: terminal E and screw terminal: terminal ) respectively.
• The 8-pin type does not have a stop input or lock input.
6
• The integrating input mode is operated by the integrated
time of the signal input. In other word, the timer operates only
when the signal input is performed.
• When the elapsed value is cleared by the reset input, the
output is reset.
• When using the unit by starting it with the power on, short-
circuit the signal terminal (8-pin: Q to R, 11-pin: E to Y and
screw: to ).
