Product Description
PLEASE NOTE: This factory installed upgrade/option is only available for purchase as an upgrade or with a new kiln. It cannot be ordered without ordering an L&L kiln.

Electronic High Limit Back Up Control

The High Limit Control is shown below the DynaTrol on the product photo.

High Limit Control

  • Bartlett High Limit Control with latching relay acts as a back up to the main DynaTrol control.
  • You set a high limit temperature on this control for the kiln.
  • If the DynaTrol fails for any reason then this acts as a "back stop" 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.

Back Up Contactor Option

  • The normal configuration for the control breaks the power to the negative of the relays.
  • However, you can also purchase this with back up 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.
