SPOTTER features:
how it works:
• Power lines are surrounded by an electric eld (E-eld).
• The strength of the E-eld surrounding the power line is dependent on several variables such
as but not limited to: voltage, the presence of multiple lines, and distance
• The NS uses a wire antenna running the length of the boom or mast of the equipment on
which it is installed to detect E-eld along it’s entire length.
• The NS detects the relative strength of the E-eld, translating it into audible and visual cues
to help you stay away from power lines.
• Adjustable sensitivity allows the NS to compensate for higher or lower voltage power lines or
overall distance from a power line
• The NS can be connected to the E-stop or hydraulic “dead-man” circuit on your pump

2. Wire harness:
plug harness into bottom of NS
external siren cable (marked with red indicators)
• run cable towards the top of turret, cab, the location where you want to mount the siren
antenna cable (marked with white indicators)
• run antenna cable towards boom and up and through pump turret leaving enough slack in the
wire to allow the turret to turn (approx 5 feet)
• securely attach harness portion of antenna as far up the boom as it will reach-securely
fastening with provided zip ties
• NOTE: the portion of antenna cable on the harness is NOT sensitive to the power line E-eld
power wires (red/black)
• the Voltek NS operates on either 12 or 24V DC power systems
• it is recommended that the Voltek NS is wired into the PTO system on your pump (when
PTO is engaged the Voltek NS will turn on as soon as it receives power and will be ready to
operate)
• run power wires (white and red) to power source that is controlled by the PTO
• use supplied splices to attach the fuse holder (fuse included) to the positive (red) lead before
connecting to power.
• connect positive (red) to power and negative to a sufcient ground
hydraulic/E-stop wires (grey/yellow)
• the Voltek NS can control either an E-stop circuit or dead-man hydraulic circuit by breaking
continuity in the circuit when the NS reaches “SHUTDOWN” (see operation)
• run wire leads towards circuit you wish to control (“dead-man” circuit that controls overall
boom movement is recommended)
• splice into circuit using provided splices
• the Voltek NS will now open a relay-breaking continuity in this circuit when in SHUTDOWN
mode causing the E-stop to shutdown or the hydraulics to deactivate (depending on which
system you have integrated this feature with).

and tighten screw
expanded view of antenna connector
• install the antenna connector on the harness end of antenna wire (see diagram below).
IMPORTANT NOTE:
Antenna wire ends MUST be connected together-otherwise the Voltek NS will indicate an
antenna fault (indicated by dashed lines on E-eld meter) and will not function.
• plug Antenna Attenuator in between harness portion of antenna (indicated by white band)
and boom portion of antenna
• the Antenna Attenuator decreases the overall sensitivity by over 50% and is used for antenna
longer than 30 meters or 100’.
• the attenuator can be removed to increase the sensitivity, however you will experience earlier
warning for power lines
You are now ready to use your Voltek NS system

Turning the Voltek NS on:
Press and hold the power button for 1 second. When Voltek NS is rst turned on it will be set to maximum
sensitivity. The Voltek RESET button also ashes for 15 seconds after rst powering up. Pushing the
ashing reset button will reset the Voltek NS to the previously selected sensitivity level when the unit was
turned off. The Voltek NS will also perform a self test of the antenna check to ensure proper operation
(E-eld strength meter will indicate self test function with a dotted line).
Adjusting the sensitivity:
The sensitivity can be adjusted using the up or down buttons. As the sensitivity increases or decreases,
the meter will display the current level of sensitivity in the overall range. When the sensitivity increases,
the range which the Voltek NS will detect E-eld gets larger and the NS indicates “warning” or “shutdown”
from a further distance. Conversely, with a lower sensitivity selected the NS will indicate warning or
shutdown from a closer distance to the power line.

E-Field strength meter:
The antenna of the Voltek NS is sensitive to certain frequencies within the E-eld surrounding overhead
power lines. The NS measures the relative intensity of these frequencies and displays this information on
the color coded E-eld strength meter.
• GREEN – Indicates relatively low E-eld strength: you are within a safe distance of operation.
• YELLOW – Indicates strong E-eld presence: you are operating within close proximity of a power
line–work carefully and remain alert. When the Voltek NS indicates WARNING on the meter, the
external siren will alert you with a pulsating tone with increasing frequency as you move closer to the
power line.
• RED – Indicates very strong E-eld - the Voltek NS will indicate SHUTDOWN and the siren will be in
full alarm with a constant tone (If installed, the E-stop/hydraulic circuits will be interrupted, stopping or
shutting down machine).
Setting the sensitivity level:
Always start with the Voltek with sensitivity set to maximum until you are able to locate nearby power
lines. Once an overhead power line has been identied, adjust sensitivity accordingly. Move equipment
to the closest proximity to the power line while maintaining a safe distance (no closer than 20 feet) and
set the Voltek NS sensitivity to indicate SHUTDOWN, then move equipment away. Now the Voltek NS is
set to your specic job-site and will prevent you from encroaching on your predetermined proximity to the
power line.
Hydraulic system/E-stop integration:
The Voltek NS has a built in relay circuit which can integrate and control the hydraulic cut out or E-stop
systems on your equipment and stop or shut down your machinery before it contacts a power line. When
the Voltek NS E-eld strength meter is in the red, it will indicate SHUTDOWN and break continuity with
the circuit it is integrated with, which will disable your machine. Once this occurs, hold down the RESET
button and move your equipment away from the E-eld until meter is back in the yellow or green. If
the reset button is released before you are back in the yellow or green, the Voltek NS will go back into
shutdown mode.
Antenna self check:
The Voltek NS conducts a self check of the antenna every 30 seconds to ensure proper operation and to
detect any faults with the system. The sensitivity meter will briey display a dashed line when the antenna
self check occurs. If a fault is detected, the sensitivity meter will continue to display a dashed line and you
will hear an intermittent tone from the siren. A fault is usually caused by damage to the antenna. If this
occurs, inspect antenna for cuts or other damage and replace if necessary.
Resetting SHUTDOWN alert: (if feature has been integrated with your equipment)
If the SHUTDOWN alert has been activated and the machinery has stopped operating or moving, press
and HOLD the RESET button to allow the operator to move the equipment away from the power line until
the E-eld strength meter is in the yellow “warning” or green level. If the button is not held until the meter
indicates yellow or green the SHUTDOWN mode will still be active.
Turning the Voltek NS off:
Press and hold the power button until the unit turns off (approximately two seconds).
System Overview and operation: (continued)
IMPORTANT NOTE: This feature is optional. For some applications, the sudden
stopping of equipment due to this feature can potentially be hazardous. It is up to
your discretion whether or not you wish to use this feature.

Linking your Spotter remote with Voltek NS
• Turn on both devices.
• Press and hold the link button on both devices for approximately 3 seconds. The link light will
ash blue (green on Voltek NS).
• While the link buttons are ashing on both devices, hold the Spotter over the Voltek NS with
the top facing down. After about 10 seconds, both devices will beep and the link lights will
turn green. The devices are now linked and communicating with each other. (If you do not do
this within approximately 30 seconds, the link procedure will be canceled and the link buttons
will stop ashing.
• Once devices are linked, they remember the link, even after powering off.
• Once the devices are linked the Voltek NS may be operated with or without the Spotter.
Operating the Voltek NS with or without the Spotter
• Voltek NS on, Spotter off: the Voltek NS will operate normally. If no wireless devices are
active, the Link button will be red.
• Voltek NS on, turn Spotter on: The Voltek NS will beep once and the Link button will turn
green. The devices wil begin communicating.
• Voltek NS on, turn Spotter off: The Voltek NS will alert the operator with a beep once every
30 seconds and the Link button will ash red/green while the Voltek NS continues to operate.
Press the Link button on the Voltek NS to stop the alert. If no wireless devices are active, the
Link button will turn red.
Understanding the Spotter Link Status Button:
• The Spotter links to one Voltek NS device at a time. Linking to a new Voltek NS causes the
previously established link to be forgotten.
• Good signal: Normal operation
• Link button is green, ashes when sending/receiving data
• Able to receive meter and status data from Voltek NS
• Able to transmit button presses to Voltek NS
• Weak signal: Unable to control Voltek NS, but still able to see Voltek NS status.
• Link button is ashing yellow
• Single beep to warn operator
• Able to receive meter and status data from Voltek NS
• Failed to transmit button presses to Voltek NS due to poor signal.
• No signal: Unable to operate
Spotter System Overview and operation: (continued)
Voltek NS User Guide Page 10

Troubleshooting:
• Link button is ashing red
• Constant beeping to warn operator (press Link button to silence)
• Failed to receive meter and status data from Voltek NS. (Displays dotted line pattern and
Warning indicator)
• Failed to transmit button presses to Voltek NS.
• Voltek NS may be powered off, out of range, or not linked to the Spotter.
• If the link button is yellow or red, try the following:
• Move Spotter closer to the Voltek NS.
• Avoid hills, large metal objects, or walls blocking line-of-sight to the Voltek NS.
• Mount the Voltek in a location that is higher or closer to a window or open area.
Battery Operation:
The Spotter comes with a 12V cigarette lighter adapter and a 120-240VAC adapter for charging
the battery. You may have the Spotter on or off while charging, but it will not display charge
status unless it is turned on. A full charge takes approximately 3.5 hours.
Battery Specications:
• Charging temperature range: -10°C (14°F) - 45°C (113°F)
• Discharging temperature range: - 20°C(-4°F) – 60°C(140°F)
• Run time: approx 15 hours
Keep in mind that actual run time can be affected by:
• Amount of activity occurring while in use
• Signal strength
• Battery temperature
• Battery age
To prolong battery life:
It is OK to perform a partial charge as needed. You do not need to “top off” the battery.
Do not keep plugged in to charger for long periods of time once it is fully charged. Keeping the
battery 100% charged increases stress on the battery and can reduce life span.
For long-term storage (several months), it is best if the battery is about 50-80% charged.
Do not leave the battery deeply discharged for long periods of time. This can permanently
damage the battery.
