? Elapsed value cleared when power is turned on.
? Time limit start initiated when start input goes on; start input ignored if time limit interval
is in progress.

Remarks
and notes
Start
? Elapsed value cleared when power is turned on.
? Time limit start initiated when start input goes on; start input ignored if time limit interval
is in progress.
? The pulse input mode starts the operation by starting the
start input.
? When using the unit by starting it with the power on, short-
circuit the start terminal (8-pin: Q to R , 11-pin: E to Y and
screw terminal: 6 to 9 ).
Start
? Elapsed value not cleared when power is turned on (power failure backup function).
? When power is turned back on, same status is maintained for output as that previous
to power going off.
? The integrating input mode is operated by the integrated
time of the start input. In other word, the timer operates only
when the start 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 start terminal (8-pin: Q to R , 11-pin: E to Y and
screw terminal: 6 to 9 ).
? Each signal input such as start, reset, stop and lock inputs is applied by short-circuiting its input terminal and common terminal
(8-pin type: terminal Q , 11-pin type: terminal E and screw terminal: terminal 6 ) respectively.
? The 8-pin type does not have a stop input or lock input.
