3.8 Special functions
The following section should facilitate the adjustment and programming of special functions.
3.8.1 Program timer / counter
Two timers are incorporated in the COMBIVERT. As long as one of the adjustable starting conditions (LE.18/
23) or a programmable input (LE.17/ 22) is set, the timer counts until reaching the final range value. If one of the
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
37/ 38 is set with reaching an adjustable switching level (LE.00...07). It can be used to set an output.
