Device Planning
Planning of a device means to reduce the functional range to a degree that suits the protection task to be
fulfilled, i.e. the device shows only those functions you really need. If you, for example, deactivate the voltage
protection function, all parameter branches related to this function do not appear in the parameter tree any more.
All corresponding events, signals etc. will be deactivated too. By this the parameter trees become very
transparent. Planning also involves adjustment of all basic system data (frequency etc.).
But it has to be taken into account that by deactivating, for instance,
protective functions, you also change the functionality of the device. If you
cancel the directional feature of the overcurrent protections then the device
no longer trips in a directional way but merely in a non-directional way.
The manufacturer does not accept liability for any personal or material
damage as a result of wrong planning.
A planning service is also offered by Woodward Kempen GmbH .
Beware of inadvertent deactivating protective functions/modules
If you are deactivating modules within the device planning all parameters of
those modules will be set on default.
If you are activating one of these modules again all parameters of those
reactivated modules will be set on default.
