Electronic Back Up Control

L91 Future Control High Limit

Back-Up Control

High Limit Control

  • Future Design Industrial FM Approved High Limit Control
  • You set a high limit temperature on this control for the kiln.
  • If the main controller fails for any reason then this acts as a "backstop" and shuts the kiln down.
  • It latches in the closed position until the High Limit control is manually reset by pressing a button on the face of the control.

Backup Contactors

  • The normal configuration for the control breaks the power to the negative of the relays.
  • However, you can also purchase this with backup contactors which will be completely redundant power contactors so that if one or more contactors fail in a closed position then the kiln still cannot climb above the High Limit set point.
