To let operator know of potentially dangerous conditions, Series TSF-DF provides visual alarm and 16 A SPST relay output when process has reached high temperature limit. Once temperature has returned to normal, non-alarm condition, unit can reset automatically or be manually reset by user. Buttons on face of control can only be used to reset alarm condition, preventing user from tampering with settings. All programming is done through master control and program configuration key.
