Product Description
The TTD™ Annunciator System is comprised of two separate components, the Display Head
unit and Control Inputs/Outputs mounted on a Plug-in Power Supply. The TTD product 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.
Incorporated in the TTD annunciator’s non-volatile memory:
• Run Hours/Elapsed Time Meter
• Last 10 Shutdowns with associated run hours
• Last 4 Alarms with associated run hours
• Selectable RS232/RS485 serial communications
• Selectable baud rates running hours
• Running hours
Optional Features:
• Pre/Post lube timed functionality
• Tachometer w/ Overspeed and Underspeed setpoints
• No-Flow Switch Detection
Display Head (TTD-H)
The 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. 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 onboard
backup battery to retain the fault display after shutdown on ignition powered units.
