The D-TEC Features:
•
Two detection modes that operate simultaneously:
o
Electric Field (E-Field) detection to sense the presence of nearby high voltage
AC
o
Magnetic Field (H-Field) detection to sense the presence of nearby high current
AC
•
An LED Look-Up Light and an Ambient Light Sensor to ensure the Look-Up Light only
illuminates when it is dark
•
The D-TEC communicates over an RS-485 link with the Universal Control Box which
acts as the communications master. This means the Universal Control Box initiates all
communication. The D-TEC only allows or disallows the operator to extend the mast and
does not provide direct power to the mast. Both the D-TEC and the Universal Control
Box perform self-diagnostic routines each time the Mast System is powered up.
Specifications for the D-TEC are listed in Table 1-3.
