9.5.2.15 Timer function overwrite | 21D |
The timer output can be overwritten for a settable time with a selectable status if required ( timer).
To overwrite the timer function by pressing keys until the next timing change => “Override Time” =
0 min.
The override time is activated by pressing a key at a digital input (example for D1 not inverted). The
bypass time can be ended prematurely by pressing another key.
If the contact remains closed, the override time also run out, then a short interruption is required to
reactivate.

Example: speed limitation over Timer (Function
| 3D | )
The timer limits the maximum speed for a certain period of time (e.g. timer ON from 6:00 - 10:00 am).
With the “Override Timer” contact the limitation (from 6:00 - 10:00 am) activated by the timer can be
cancelled for an adjustable period “Override Time” (
timer / timer function overwritten: Override
Status = OFF)
To activate the limitation outside the programmed time (10:01 - 5:59 am) => “Override Status” = ON
9.5.3 Configuration of analog inputs “E1”and “E2”
9.5.3.1 Signal adaption E1 and E2
If required, an adaptation of the specification signal / speed characteristic curve is possible
Information
Setting options depending on the version of the software available!
These settings are mostly practical for the operating mode with rotational speed specification over an
external signal. In operating modes (as of 2.01) this setting is not suited for influencing the regulation
process.
