Setting curve
The resistance value to be set depends on the nominal secondary trans-
former current and the temperature gradient of the transformer and results
from the following setting curves:

Example:
Nominal secondary transformer current: 1.9A
Required gradient: 26K
Resistance value from setting curve: 6.2Ω
ü Open the cover plate.
1. Determine the necessary resistance value from the setting curve (6.2Ω in
this example).
