In elapsed time mode, the present value returns to 0; in remaining time mode, the present value returns to the set value.
• The following table shows the delay from when the reset signal is input until the output is turned OFF. (Reference values)
Inputs
Count
• Reads counting signals.
• Increment and decrement inputs accepted.
Reset
• Resets present value and outputs.
*2
• Counting cannot be performed during reset input.
• Reset indicator is lit while reset input is ON.
