Understanding and Using the Handheld
Transmitter Indicator Lights
The individual holding the transmitter can push the Lock
Drill (Off) button to stop the drill rotation and thrust. This
is primarily used to stop/lockout the drill operations in the
following situations:
•
When installing or removing a drill head or reamer
•
Whenever someone needs to approach the drill pipe or
head anywhere in front of the machine
•
Placing a wiper on the drill pipe
•
When the locator operator identifies a problem requiring
immediate shutdown of drilling
When it is safe to resume drilling, the individual holding the
transmitter can press the Unlock Drill (On) button. This
button sends a signal to the receiver that allows the machine
operator to reset the system and restore the thrust and rotary
functions.
The following table lists the various states of the indicator
