Brand New
Manufacturer warranty Description
The LCDT Selectronic Tattletale system is a compact fault annunciator with an electronic alarm/shutdown control system. It's designed to protect engine-driven or motor-driven compressors and pumps. The annunciator indicates the sensor, and hence the parameter, that causes an alarm or shutdown. In addition, a means is provided for testing the operation of each sensor without initiating an alarm or shutdown. Employing a liquid crystal display, the LCDT system gives a digital reading of the tripped sensor and the lockout timer countdown.
Intended for use with all Swichgage instruments without OS option.
Features:
- Timed start up override for up to 15 sensors
- Liquid Crystal Display of tripped sensors and the lockout timer countdown
- Test timer for shutdown override during sensor test
- Intrinsically safe annunciator unit: Class I, Division 1, Group D Hazardous Locations
- Explosion-proof power supply
- Battery power to maintain electronics while engine is not running
