Control Panel

  • The Series 7550 is a family of self contained control panels that provide a complete control system designed for accurate and safe control of our inline air heaters.
  • These control panels contain a proprietary microprocessor based Process Controller and solid state relay, which uses rapid response technology to provide accurate air temperature control.
  • The control system also has an independent high limit controller that de-energizes the built-in safety contactor if an unexpected condition attempts to overheat the heating element.

Recommended Fusing

These ultra fast blow fuses are recommended as protection for the power circuits within the controller. The power circuits contain Solid State Relays (SSRs) that are sensitive to any overcurrent or short circuit conditions. Standard fusing will not open quickly enough to protect the SSRs.

If these recommended fuses are not used and the heater power is shorted internally or to ground, it is probable that the SSRs will fail in a permanently closed state. After appropriate repairs, and upon restarting the controller, the result will be power continuously applied to the heater causing a runaway heat output condition if the SSRs have not been replaced. Using the recommended fusing should prevent this.

These fuses must be appropriately installed in series with the incoming power to the controller. Contact the fuse supplier or their distributor for installation details.
