Figure 57 - OFF-delay Timer Function Block Diagram
The OFF-delay timer function block performs a timer operation for an OFF-
delay set in 10 ms increments. The range for this delay is from
0 ms…300 seconds. The default setting is 0 ms.
(1) The Output Enable signal will not turn ON if the synchronization time requirement is not met (that is, operation inputs for both
hands must be completed within 500 ms), but this is not considered an error.
