How to proceed the transformer adjustment (with topped filtering board):
1. Measuring of the terminal voltage on the ceiling terminal.
2. The terminal voltage of the emergency supply is similar to the reference value (D.C.). The reference value (D.C.)
is measured on the ceiling tube’s terminal connection situated behind the filtering board. The secondary tap on the
transformer should be chosen in that way that the above measured reference value (D.C.) is reached. This proce-
dure is valid for separately mounted transformers with filtering board as well as on ceiling tube mounted trans-
formers with filtering board.
The following taps can be chosen:
