Digital Tattletale by Murphy Selectronic®
The LCDT Selectronic® Tattletale® is a compact fault annunciator
with an electronic alarm/shutdown control system. It was designed
to protect engine-driven or motor-driven compressors and pumps. The
Tattletale® 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 gives a digital
reading of the tripped sensor and the lockout timer countdown.
As the heart of the system, the LCDT’s basic annunciator component
has two variations: the Model LCDT-NO, which accommodates normally
open sensors, and the Model LCDT-NC, which accommodates normally closed
sensors. The LCDT accommodates 47 sensor inputs, 15 of which may be
locked out during start-up by the start/run timer delay.
