The TTD-H is a solid-state fault annunciator and shutdown control system designed to protect engines, compressors and their associated equipment. The TTD model will accept 48 sensor inputs from normally open and/or normally closed sensors. Each of the 48 inputs can be configured for Shutdown or Alarm Only. Any input can be locked out by one of the two Start-Run timers, or configured as Class C, ESD or Ignore. The annunciator provides for both closing of a fuel valve and grounding of an ignition after a time delay.

The TTD-H Display Head displays operational and configuration data. Configuration parameters are entered via keypad or download from MConfig software. The operator interface will accept digital inputs directly on the back of the unit. Power is provided to the Display Head via a direct Phoenix connector or a cable connecting to a remote mounted power supply (Murphy Part #: PSU-2-T [50700594] / not included). The display head contains the microprocessor, the Liquid Crystal Display (LCD), the membrane keys for configuring the sensors inputs and the sensor input terminal blocks. The TTD liquid crystal display annunciates any fault from the sensor inputs, displays engine speed, and elapsed time. Other features for the TTD model are: built-in Test Mode to test the sensor circuits without shutting down, Pre-lubrication and Post-lubrication timers, and on-board backup battery to retain the fault display after shutdown on ignition powered units.
