Check that the transformer(s) are sized properly.
• If a common transformer is used, make sure that polarity is observed on the secondary. This means connect all No. 1 wires to one leg of the transformer and all
No. 2 wires to the other le
g
of the transformer.
• If multiple transformers are used with one control si
