ZAP ALERT
TM
OPERATING INSTRUCTIONS
WARNING: It is important to read and understand
these instructions before using the
ZAP-ALERT
TM
.
The ZAP-ALERT
TM
is an electrical power line strike indica-
tor to be used in conjunction with earth boring equipment.
The
ZAP-ALERT
TM
signals contact and damage to buried
power lines from 100 volts AC to 100,000 volts AC. Any
voltage over 42 volts peak between the
ZAP-ALERT
TM
unit and the grounding stake will trigger the alarm.
WARNING: The ZAP-ALERT
TM
will not be set off by
coming near a power source. It only sounds an alert
after electrical contact has been made. Safety equip-
ment and safety apparel must be used at all times.
Mounting:
The ZAP-ALERT
TM
is mounted under the console.
The power outlet for ZAP-ALERT
TM
is adjacent to it. The
female receptacle is used to bring power from the power
cable to the
ZAP-ALERT
TM
siren.
OPERATION
Power Source:
The ZAP-ALERT
TM
uses a standard 12-volt DC power
source. Connect the black wire of the power cable to
the positive (+) battery terminal and the white wire to the
negative (-) battery terminal. Do not use any fuses in the
lines powering the
ZAP-ALERT
TM
. The ZAP-ALERT
TM
must always have power whenever in use. Do not con-
nect the power source to a switch that may inadvertently
be turned off while working.
Plug the power cord into the female receptacle on the
console.
Sensing Stake:
The sensing stake should be connected to the insulated
bolt on the front of the
ZAP-ALERT TM box. Push the
sensing stake into the ground at least 6’ away from the
equipment,
perpendicular to the bore path . It is im-
portant for the earth stake to be inserted into soil which
electrical current can pass through. If the earth stake is
in extremely dry soil or asphalt, the ZAP-ALERT
TM may
not function. If it must be inserted in extremely dry soil,
moisten the soil around the sensing stake to improve soil
conductivity. Be sure to fully insert the sensing stake into
the ground.
Insulated Blanket:
The insulated blanket should be positioned to protect the
operator from inadvertent contact with the pit wall. Place
the blanket in the desired position and install the stakes in
the ground to hold the blanket in place. Drive the stakes
fl ush with the ground.
Testing:
Connect the power cord to the power source and to the
female receptacle on the console. Lay the sensing stake
on the ground. (Do not insert the stake into the ground
at this time.) Connect one lead of the test set to the
sensing stake. Connect the other lead to an exposed
metal part on the machine. Press the test button on the
hand held tester. Check that the
ZAP-ALERT
TM
siren is
sounding. When you have confi rmed the operation of the
ZAP-ALERT
TM
, press the reset button to stop the siren.
WARNING: Do not operate the machine unless the
test system confi rms that the
ZAP-ALERT
TM
system
is operational.
Resetting After A Strike:
Once you have made a strike, the siren will continue to
sound as long as current is passing into the machine and
soil. If you attempt to reset the
ZAP-ALERT
TM
, the siren
will not stop until the current has stopped.
WARNING: Do not stop the siren by resetting the
ZAP-ALERT
TM
until you have confi rmed that the elec-
tric power has been locked out. If the power has not
been properly shut off , an automatically resetting
circuit breaker could reenergize the power line, or
contact between the boring tool and power line may
recur if they are close to each other.
