Note: 1. Allow at least 0.1 s for the Timer reset time if the power
supply is reset due to an interruption in the power supply.
2. The minimum input pulse width (for start, reset) is 0.05 s.
3. The letter "t" in the timing charts indicates the set time, and
"t-a" means that the period is less than the set time.
(t - a < 1)
4. In J Mode, there will be only one output even if the start input is
longer than the set time.
5. H3CR-AP model incorporates start input only. As such, the
power supply is reset.
6. Model H3CR-AS only has operation equivalent to time-limit
contact: NO.
7. When the setting dial is turned all the way past 0 for
intantaneous output, "t" (set time) in the above time chart is
0-sec operation.
8. During timer operation, the flash frequency changes when
90% of the set time has been reached.
Start and reset are also both enabled when the gate signal is ON.
