The cable used to connect the Sensor unit to the RCP should be connected to the bottom of the
Sensor unit and wired into the RCP PC board as shown.

D-TEC® Functionality
The optional D-TEC® Sensor provides additional limited protection against raising the mast into
power lines. On Night Scan fold-down units, as soon as the mast begins tilting, the control begins
initiating the D-TEC® Sensor and self-tests it until it either passes, or the mast reaches the point
where the RCP becomes active (at 90°). Assuming that it passes, the operator is then permitted
to extend the mast. For vertical mast applications, the self-test is performed during power up and
the unit begins actively sensing. If the mast senses an electrical field strength above the alarm
threshold, the mast will stop extending even though the operator continues to push the "Mast Up"
button. In this case, there will be a message displayed on the alphanumeric display of the
Remote Control(s) (for Night Scan models). If the operator believes the sensed condition to be
false, they may clear it in either of two ways: momentarily initiating an Auto Stow® function, or
lowering the mast to the bottom of the 90° position (for fold-down models). This will clear the
alarm and allow the operator another chance to raise the mast to its full extension. The following
messages may be displayed on the Remote Control(s).
The following table contains possible D-TEC® messages:

D-TEC® Testing
The D-TEC®
Sensor is
performing a self-
test.
The D-TEC® has repeatedly been trying to pass
the self-test while moving to the RCP active
position. Normally, it will pass one of these
attempts and no message will be displayed. If not,
once there it tries one more time to pass and this
message will displayed during the self-test.
Power Line E-Field
The D-TEC® has
sensed voltage
from a power line.
A power line may be in close proximity. If so, move
the vehicle to a location away from the power line,
and then redeploy the system.
