Timer
n Timer Time
The time set for the timer is the delay time for the ON-delay timer, the delay
time for the OFF-delay timer, or the pulse width for the one-shot timer. Set
the time according to the requirements of the control system (e.g., PLC).
The timer time can be set to between 0 and 5,999 ms.
n Timer Disable
If the timer is disabled, judgement outputs will be made immediately and
the output response time will be determined by the number of samples to
average.
n OFF-delay Timer
When the measured value changes from HIGH to PASS or from LOW to
PASS, turning OFF the PASS output is delayed for the timer time.
n ON-delay Timer
When the measured value changes from HIGH to PASS or from LOW to
PASS, turning ON the PASS output is delayed for the timer time.
n One-shot Timer
When the measured value changes from HIGH to PASS or from LOW to
PASS, the PASS output is turn ON with a pulse width equivalent to the
timer time.
When PASS output pulses overlap, the latter pulse has priority. Therefore,
overlapping pulses might sometimes become a single pulse rather than
separate pulses.
Note: Neither the HIGH nor the LOW output are output when the one-shot timer
is selected.
Refer to 4-5-6 FUN Mode Status Transitions.
