Brake Transformer
The transformer powering the brake board can be set from 80 VAC
to 280 VAC depending on tap settings and whether taps are connected in series or parallel.
Maximum power is 300 VA. This setting is made at the factory per your configuration selec-
tions.
If you are unable to achieve adequate brake current, check transformer wiring. If the windings
are wired in series; rewire in parallel.
If coil current is excessive, check transformer wiring. If the windings are wired in parallel;
rewire in series.
