All parameters are set on an additive basis. Some parameters
have fixed upper and lower thresholds.
If you set a value below the minimum setting, the minimum
setting applies.
If you set a value above the maximum setting, the maximum
setting applies.
Parameters marked with "∞"allowtodeactivate the associated
protection stage. To do so, set all switches to "on" position.
The setting ranges for the parameters can be found in the
Technical Data (2.11) or on the indications on the front panel.
