Topics covered in each DVD

This program covers the most common switches, timers, and control devices found in your plant. You have hundreds (probably thousands) of these devices in your plant. At a cost of $25 to $250 per component, this program will quickly pay for itself.

We show how these devices work, how they are wired, and how to troubleshoot them. This program also provides the first step in learning ladder diagrams.

Solve Even the Trickiest Component Failures
  • Avoid costly wiring mistakesóread multiposition selector switches in ladder diagrams
  • Read the action and timing diagrams of ON-delay and OFF-delay timers so that when something goes wrong, you'll know exactly which component to
  • Avoid intermittent problemsómake sure control relays are receiving the proper steady voltage
  • Learn how to cut your spare parts inventory to a minimum since many control devices share components
  • Troubleshoot tricky push button problemsódon't replace the whole thing when it might just be the contact blocks
