3.2.2.1.4 Parameter window - Startup/Run-on
This parameter window is visible if the Startup/Run-on parameter in Parameter window A: Fan (Multi-
level) , p.21 is set to Yes .
Start-up behavior
Options: No
Yes
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.

Yes : The following parameters appear:
Switch on over fan speed
Options: 1/2/3
Here you set which speed the fan uses to start from the OFF state.
Minimum dwell period
in switch on fan stage in s [1...65,535]
Options:
1…5…65,535
This parameter defines the minimum dwell time for one of the switch on speeds.
