Subsite 86Bv2 Series Operation instructions

FCC Statement
This device complies with Part 15 of the FCC Rules. Operation is
subject to the following two conditions: (1) this device may not cause
harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
Changes or modifications not expressly approved by The Charles
Machine Works, Inc. could void the user’s authority to operate the

This equipment has been tested and found to comply with the limits for
a Class A digital device, pursuant to Part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the
operator’s manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is
likely to cause harmful interference in which case the user will be

86Bv2/86BGv2
Series Beacons
The Subsite®Electronics dual frequency 86Bv2/86BGv2
series beacons are designed to function as one part of a
guidance system for horizontal directional drilling units.
These 29 kHz (and 12kHz with dual frequency option)
beacons transmit roll angle, beacon temperature,
beacon battery status, and pitch information and
perform best in Ditch Witch®approved tool housings.
To prolong battery life, these beacons sleep after 20
minutes with no roll and wake when rolled completely
around twice. To allow beacon to enter sleep mode after
5 minutes, roll beacon to 5 o’clock.
Communication Features
Roll angle transmission: 12 positions.
Beacon temperature: sent in 10% steps to 100% and
in 5% steps from 100% to 120%.
Typical operating temperature is 70% or less.
However, temperature spikes can destroy beacon
before operator can cool beacon down. If
temperature goes above 70%, stop drilling, pull
back 3’ (.9 m), and pump fluid into hole until beacon
cools down.
NOTICE:
• Operating beacon at temperatures above 100%
will cause beacon overheating and failure and will
void beacon warranty. Monitor beacon
temperature carefully.
• Operating fluid-assisted drilling system without
proper fluid flow will cause overheating and
damage to beacon and tool head.
Beacon battery status: sent in 20% increments.
Pitch: sent in ranges from -100 (45° down) to +100 (45°
up).• sent in 1% increments for standard beacon
• sent in 0.1% increments up to 45%, then 1% up to
100% with grade option.
Troubleshooting
Beacon will signal operator if error is detected during
self tests. If you see one of these signals, contact your
Ditch Witch®dealer.
Pitch Sensor: beacon transmits alternating plus and
minus signals instead of pitch readings. Pitch readings
will be unreliable until problem is corrected.
Power Regulation: beacon regulates antenna power
level over battery life.
• If beacon is unable to maintain regulation, it will
signal operator by cycling battery status (100%, 80%,
60%, 40%, 20%, 0%, 100%, 80%, . . .). Do not
attempt depth estimates.
Possible reasons for this warning are:
• beacon damage • wrong type of batteries
• bad tool housing • ignoring low battery warning
• incorrectly installing beacon into tool housing
• using alkaline batteries in AT tool head

NOTICE: High temperature is the primary
cause of beacon failure. Monitor beacon
temperature carefully.

ORIGINAL INSTRUCTION

Install Batteries and
Select Frequency
1. Unscrew cap.
2. Check for and correct the
following conditions:
• dirty or damaged threads.
• missing, dirty or worn foam
washer on battery cap and
bottom of battery chamber.
• missing, worn or damaged
springs.
• missing, damaged or dirty
o-ring. Clean or replace as
needed.
3. Insert, positive end first, one Power Stick battery
(p/n 222-1369) or one Electrochem CC 3.67 V
Lithium.
Dual Frequency Beacons:
•To select 12 kHz frequency, hold beacon vertical
to the ground with the forward isolator pointed
toward the ground.
•To select 29 kHz frequency, hold beacon vertical
to the ground with the forward isolator pointing
toward the sky.
4. Install batteries. Keep beacon steady while hand
tightening cap firmly. Use tracker to confirm beacon
is functioning.
Note: Frequencies may be switched after they are
initially set. See “Switch Frequency While Drilling”
section.
IMPORTANT: For maximum performance, use only
Power Stick battery (p/n 222-1369) or Electrochem CC
3.67 V Lithium batteries. Standard “C” cell alkaline
batteries can cause intermittent operation and beacon
signal errors.
Test Operation
Use a tracker to test beacon function before leaving for
jobsite and after every battery change.
To test beacon function:
1. Turn on tracker, select frequency (if equipped with
dual frequency) and adjust gain so that signal
strength is approximately 50% (see tracker
operator’s manual).
2. Roll beacon and look at display for corresponding
roll positions.
IMPORTANT: When flat top on front isolator is at 12
o’clock, beacon should be sending 3 o’clock to
tracker.
3. Tilt beacon and look at display for corresponding
pitch positions.
4. Check beacon battery status and temperature.
For best results, replace batteries daily. (Using weak
batteries can cause erratic signal and/or damage.)
Recalibrate tracker to beacon after changing batteries.
Install Beacon into Tool Housing
IMPORTANT: Check beacon operation and condition of
both isolators before installing beacon into tool housing.
1. Lay beacon into tool housing with flat top isolator
toward bit and flat side facing up.
2. Check for proper beacon alignment by rolling
housing on the ground and watching for
corresponding roll positions on tracker display.
IMPORTANT: After installing beacon into tool housing,
calibrate tracker for each frequency before drilling.
Calibrate Tracker to Beacon
1. Select beacon frequency, if necessary.
2. Install beacon into drill head and place on ground
exactly 10’ (3 m) away from tracker. Make sure no
metal objects including drilling unit and drill pipe are
within 20’ (6 m) of tracker and toolhead.
3. Position tracker parallel to center of drill head.
4. Turn tracker on and press and hold depth and up
arrow keys until calibration mode is entered.
Release keys.
5. Verify calibration by moving tracker 15’ (4.5 m) away
from toolhead. Check depth. If reading is not 15’
(4.5 m), recalibrate tracker.
6. Repeat for other frequency, if needed.
Switch Frequency While Drilling
(Dual Frequency Option)
1. Allow beacon to go to sleep.
2. Rotate beacon within a minute of it going to sleep to
switch frequency.
If beacon is rotated after it has been asleep longer
than a minute, the frequency will not change.
Remove Beacon from Tool Housing
IMPORTANT: Remove beacon before mud in beacon
chamber hardens and locks beacon into housing.
1. Remove beacon from tool housing.
IMPORTANT: If beacon will not come out, do not
use force. Try soaking housing in water until dried
mud inside housing softens. If beacon still will not
come out, contact your Ditch Witch®dealer for
advice.
2. Clean beacon and remove battery.
3. Wash and lubricate tool housing.
