reset conditions (LE.20/25) is met or one programmable input (LE.19/24) is set, the timer jumps back to zero.
The clock source and the counting direction is adjusted with LE.21/26. It can be counted in seconds, hours or
by a special programmed input for that. The current timer content is displayed in ru.43/44. Switching condition
