Refer to the functional description and be sure the settings you choose result in relay
performance appropriate to your application.
As you enter settings, they are compared with setting limits above. Then the relay computes
internal settings from your entries and checks to ensure that they fall within the specified
range.
For example, let CTR= 1000 and 50N1 = 1. Each of these settings is admissible alone, but
together they result in a secondary pickup setting of 1 mA, which is out of range. Internal
setting error messages indicate out-of-range settings after you enable the new settings (refer to
the Specifications for the secondary ranges of the relay elements).
The AUTO setting selects PORT 1, 2, or both of the two serial ports for automatically
transmitted messages. The table below shows the effect of each possible setting:
