Description :
The operation On-Delay timer retentive counts the time when the qualification input is active (ON). The timer bit is activated when the current value becomes greater than or equal to the preset time (PT). When the qualification input is deactivated (OFF), the current value of the On-Delay timer retentive is maintained. This allows to accumulate the time for more activation periods of the input. The current value of the timer can be reset with the input (R). The timer goes on counting once reached the preset value and sops when once reached the maximum value 32767.
