Output quantity can be adjusted by changing the cycle time set in the
adjustment level to 1 and by changing the ON duty (%) set value. The set value
shows the ON duty (%) and can be set to a value between 0 and 100 (%).
When the cycle time is 0, the output will always be OFF. When the cycle time
is not 0 and when ON duty has been set to 0 (%), the output will always be
OFF. When ON duty has been set to 100 (%), the output will always be ON.
Output mode D: Signal OFF-delay (Timer resets when power comes ON.)
Output mode E: One Shot (Timer resets when power comes ON.)
Output Mode F: Cumulative (Timer does not reset when power comes ON)
