See https://www.youtube.com/video/Z8WCjC1IPwk?ecver=2

How to check the operation of a control transfomer on an L&L automatic kiln. Applies to all automatic kilns that are not 480 volts. The control transformer reduces the incoming line voltage from 240, 208 or 220 volts to 24 volts for the control and 12 volts for the relays.

Parts
  • See this page for 12 KVA control transformers used on kilns with three sections or less.
  • See this page for 30 KVA control transformers used on kilns with four or more sections.
