Parameter window - Startup/Run-on

This parameter window is visible if the Startup/Run-on parameter in
level), p.21 is set to Yes.
Start-up behavior
Options:
This parameter enables the fan to start from the OFF state with a defined fan speed. This fan speed is
immediately applied.
In order to guarantee that the fan motor starts safely, it can be useful to start it on a higher fan speed first
so that the torque is higher during start-up.
Note
However, with a step switch, the previous fan speeds are switched on consecutively. With the changeo-
ver switch the fan speed is switched on right away.
The delay between the switchover of two fan speeds (contact change) is taken into account.
The dwell times in a fan speed, which are taken into account in automatic operation, are inactive and will
only be taken into account after the start-up phase.
The start-up behavior is a technical characteristic of the fan. For this reason, this behavior has a higher
priority than an active limitation or forced operation.
