Murphy Display Head for TTD Series Fault Annunciator - TTD-H

The Murphy Display Head TTD-H 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.

FEATURES:

• Fully-configurable fault annunciator
• Alarm and shutdown control system for engine-driven pumps and compressors
• Monitors 48, user-configurable, sensor inputs from N.O. and/or N.C. sensors
• User selectable templates provide ease of retrofit by selecting configuration of existing annunciators via display keypad or download from computer with windows based MConfig installed
• Serial communications port with selectable baud rates up to 38,400
• One display head is common to all configurations allowing fewer spare parts required to be maintained in the field
• CSA Class I, Division 2, Groups B, C, and D
• Intuitive display icons to display status and assist in setup and operation result in greater ease of operation and interface
