H5AN

Note: 1.

When a rated time of 99 min 59 s or 99 h 59 min is selected, the overflow values of the digital display when using the DOWN (countdown) 
function will be indicated as 9959, 9958, 9957, ... in modes F, K, and Q.

2.

In this timing chart, the number of step advances during the one-shot time varies in accordance with the selected rated time and duration 
of the one-shot time.

3.

In C and P modes, set time value n should be sufficiently longer than the one-shot time t.

K

In UP mode, the digital display 
continues to increment up to “9999”, 
even after reaching the set value and 
then returns to all zeroes. In DOWN 
mode, the digital display continues up 
to 9999, and the decrements “9998, 
9997, ...,” after reaching all zeroes. 
The timer restarts the timing operation 
when the incrementing or 
decrementing value reaches the set 
value.
The output is generated during the 
one-shot time. The timer repeats this 
cycle.

P

For the digital display, the value at the 
up is held during the one-shot time; 
however, the timing operation of the 
timer returns to the initial setting when 
the set time has elapsed and the timer 
restarts the timing operation. When 
the set time has elapsed, the output 
signal is generated during the one-
shot time. The timer repeats this cycle.

Q

In UP mode, the digital display 
continues to increment after reaching 
the set value during the one-shot time. 
In DOWN mode, the digital display 
continues to 9999 and then 
decrements “9998, 9997, ...,” after 
reaching all zeros during the one-shot 
time. However, in both UP and DOWN 
modes, the digital display returns to 
the initial setting after the one-shot 
time and the timer restarts the timing 
operation. When the set time has 
elapsed, the output signal is 
generated during the one-shot time. 
The timer repeats this cycle.
