OFF-delay Operation by External Signal
Upon power application (connect power to terminals A and X short-
circuit terminals M and O when using the 12/24 VDC operated timer
with 12 VDC power supply) and start input application (short-circuit
terminals F and A), output is produced immediately, and if the start
input is continuously applied, the time-limit operation can be sus-
pended by applying a reset input before the set time has elapsed.
(Although the reset input has been continuously applied before ap-
plying a start input, output will be produced upon applying a start in-
put.)
With terminals A and D short-circuited, the time unit initiates the
time-limit operation upon opening these terminals and when the set
time has elapsed, output is reset.
When operating an external start or reset input contact, the current
that flows from terminal F to terminal A (start input) or from terminal
D to terminal A (reset input) is approx. 0.1 mA. Therefore, use of a
high-reliability contact is recommended for start and reset inputs.

When using the 12/24 VDC operated timer with a 24 VDC
power supply, open terminals 13 and 15.
Others
When cleaning the timer, confirm that the sealing tape is securely in
place. Do not clean without this sealing tape affixed.
Use alcohol type (IPA, ethanol) solvent which are less chemically
reactive. Note that use of other solvents may damage the materials
used for the timer. Clean the Timer in less than 2 minutes. The
cleaning solution must be 50_C or less.
The tails of the connecting leads are solder-plated with consider-
ation given to temperature at the time of soldering. When soldering
the leads, keep the temperature at 260"C!5"C and complete sol-
dering within 10 s.
