Important Safety Instructions

Your Skymetry WTU-14 has been carefully designed to give you years of safe,
reliable performance. As with all electrical equipment, however, there are a few
basic precautions you should take to avoid hurting yourself or damaging the unit:

• Read the installation and operating instructions in this manual carefully. Be
sure to save it for future reference.

• Read and follow all warning and instruction labels on the product itself.

• To protect the Skymetry WTU-14 from overheating, make sure all openings
on the unit are not blocked. Do not place on or near a heat source, such as a
radiator or heat register.

• Do not use your Skymetry WTU-14 near water, or spill liquid of any kind into
it.

• Be certain that your power source matches the rating listed on the AC power
transformer. If you’re not sure of the type of power supply to your facility,
consult your dealer or local power company.

• Do not allow anything to rest on the power cord. Do not locate this product
where the cord will be abused by persons walking on it.

• Do not overload wall outlets and extension cords, as this can result in the risk
of fire or electric shock.

• Never push objects of any kind into this product through ventilation holes as
they may touch dangerous voltage points or short out parts that could result in
a risk of fire or electric shock.

• To reduce the risk of electric shock, do not disassemble this product, but
return it to Sensaphone Customer Service or another approved repair facility
when any service or repair work is required. Opening or removing covers may
expose you to dangerous voltages or other risks. Incorrect reassembly can
cause electric shock when the unit is subsequently used.

• If anything happens that indicates that your Skymetry WTU-14 is not
working properly or has been damaged, unplug it immediately and follow the
procedures in the manual for having it serviced. Return the unit for servicing
under the following conditions:

1. The power cord or plug is frayed or damaged.

2. Liquid has been spilled into the product or it has been exposed to water.

3. The unit has been dropped, or the enclosure is damaged.

4. The unit doesn’t function normally when you’re following the operating
instructions.

iii

CAUTION: To reduce the risk of fire or injury to persons, read and follow these
instructions:

1. Replace the battery only with the same or equivalent type recommended
by the manufacturer.

2. Do not dispose of the battery in a fire. The cell may explode. Check with
local codes for possible special disposal instructions.

3. Do not open or mutilate the battery. Released electrolyte is corrosive and
may cause damage to the eyes or skin. It may be toxic if swallowed.

4. Exercise care in handling battery in order not to short the battery with
conducting materials such as rings, bracelets, and keys. The battery or
conductor may overheat and cause burns.

Chapter 1: Introduction

Chapter 1: Introduction

Congratulations on your purchase of the Skymetry WTU-14 by
Phonetics, Inc.

The WTU-14 Wireless Telemetry Unit is a powerful monitoring,
alarm, and control system. Its built-in wireless technology means
you won’t need a telephone line to communicate with the unit. It
can monitor and control your environment and equipment using
eight dry contact inputs, six analog inputs, built-in power failure
detection, and two relay outputs. It can perform simplex or duplex
alternating pump control using a level transducer or float switches.
The unit can also perform machine-to-machine control among mul
tiple WTU-14 devices. Up to 8 machine-to-machine control algo
rithms can be configured per device so that input conditions on one
Skymetry WTU-14 can logically control outputs on another using
simple, fill-in-the-blank, comparison programming. The unit fea
tures several communication options including: voice telephone call,
e-mail, and text messaging. You can also request a status report
from most two-way text devices, like alphanumeric pagers and
cell phones. The Skymetry WTU-14 is fully programmable via the
included Skymetry Software package for Windows or through the
unit’s web page at www.skymetry.com.

-

-

-

The WTU-14 will produce a web page of input and output status
and alarm history that can be viewed at www.skymetry.com. You
can also program the unit or control outputs from the web page.
The Skymetry is the ultimate choice for remote monitoring and
control where telephone lines are non-existent or too expensive.
Applications include pump houses, cable TV huts, remote equip

-

ment rooms, and tower light monitoring.

On the front of the unit are LED indicators to show the operat

­ing status (Power, Battery OK, In-Range, Registered, Alarm, and
Outputs). All programming is stored in nonvolatile memory so that
all programming is retained even without power. The unit will per

­form alarm event logging of the 14 inputs, power, and battery to the
Skymetry web page. A complete status report of all monitored con

ditions can be retrieved via e-mail for viewing on a computer or text
messaging device. The Skymetry.com web page can be updated on
demand to allow viewing of the current conditions at the site from
any internet-connected computer. The unit comes in an aluminum
housing with mounting tabs and is optionally available in a plastic
NEMA-4X enclosure with a 36-hour battery backup.

Web Page Initialization

Your Skymetry WTU-14 is accessible via the internet at www.
skymetry.com. From the web page you can view status, make
programming changes, and even control outputs. Before any of
these features can be utilized, the unit must first initialize the web
server. This happens automatically immediately after your f irst local
programming session with the unit. As soon as you disconnect from
your first programming session the unit will begin to update the
web server with all of its programming. This may take an hour or
two depending on how many parameters were programmed. During
this initialization period it is recommended that the unit remain
powered on and no additional programming changes take place. For
detailed information on the Skymetry web page see Chapter 10.

Data Message Usage

Your Skymetry WTU-14 communicates over the wireless network
using data messages. These are transmitted whenever an alarm mes
sage is delivered, machine-to-machine command is sent, or a web
update is requested. The number of data messages used for each
type of transmission is shown below in the table:

Programming Refresh to the Web Page 9 to 115

The last item, Programming Refresh to the web, depends on how
many changes were made since the last update. Only items that have
changed will be sent. Typically, once the unit has been programmed,
additional programming changes are minimal. However, if you were
to completely reprogram the unit and change every parameter, then
the maximum number of data messages would be transmitted.

Chapter 2: Installation

Operating Environment

The Skymetry WTU-14 should be mounted and operated in a
clean, dry environment. The unit must communicate to the wireless
network, so care must be taken not to install the unit inside a metal
cabinet or other location that will prevent the unit from receiving
a radio signal unless the antenna can be relocated to a location
free of obstruction. The unit is microprocessor-controlled and, as
a result, should not be installed near devices that generate strong
electromagnetic fields. Such interference is typically generated by
power switching equipment such as motors, contactors, or variable
frequency drives. Where this is unavoidable, mount the unit in a
separate, grounded steel enclosure with an external antenna (see
Appendix F: Accessories). A poor operating environment may result
in unwanted system resets and/or system lockup. The temperature
range the unit can operate in is -20°F to 158°F (-29°C to 70°C).

Activating your Skymetry WTU-14

Your Skymetry device must be activated on the wireless network
before you can send or receive messages
gramming is performed for the first time.

To activate your Skymetry WTU-14 device, fill out the activation
form included with the package and follow the instructions, or con
tact your sales representative with the device serial number.

Your Skymetry WTU-14 is activated when the “In Range” and
“Registered” LEDs are lit.

sider placing the unit inside of a cabinet for safety. Use a plastic
or fiberglass cabinet to minimize the signal loss on radio reception.
When installing the unit inside of a metal cabinet, be sure to use an
external antenna as the metal will shield the unit from receiving a
radio signal.

On the top and bottom of the housing are mounting holes to attach
the unit to either a panel or wall. The mounting surface should be
sturdy enough to support 2 lbs.

The unit should be mounted using four #10-32 bolts where appro

­priate, or four #10 tapping screws. (The screw kit for the Skymetry
WTU-14 includes (4) #10-32 screws, (4) #10-32 nuts, and (4) #10
lockwashers). When mounting the unit to a wall, make sure the
mounting screws fully engage a solid member (for example, a stud)
of the support structure. Mount the Skymetry WTU-14 in an upright
position so that you can easily connect wires to the terminal strips.
The dimensions of the enclosure are: 8.0" x 6.1" x 1.6". See Figure 1.

Antenna Information

The Skymetry WTU-14 comes with a unity-gain stub antenna
designed specifically for the frequency range required. In order
to comply with FCC RF exposure, the external antenna must be
mounted in a location where people will never come within 20cm of
the antenna. The gain of the antenna may not exceed 0dBi. For opti
mum antenna performance, there should be no metal objects within
close proximity of the antenna.

-

WARNING Do not over-tighten the antenna on the
Skymetry WTU-14; this may cause

permanent dam-

age to the device.

The antenna must be connected before the device is powered up.

Connecting the Power Supply

The Skymetry WTU-14 requires a 15VDC 800mA power supply
(part number FGD-8250) to operate. This power supply will charge
an external 12V battery (2–12AH) and provide the necessary power
to transmit messages over the wireless network.

WARNING: Do not substitute supplies with lower
capacity.

Connect the positive terminal of the Power Supply to the +Vin ter
minal on the Skymetry WTU-14.

Connect the negative terminal of the Power Supply to the -Vin ter
minal on the Skymetry WTU-14.

Connecting a Battery

In the event of a power failure, the Skymetry WTU-14 can oper­ate from a 12V sealed lead-acid gel-cell rechargeable battery. The
duration of battery time depends on the capacity of the battery (see
chart below). The unit incorporates circuitry to maintain the proper
charge for a 12V gel-cell battery whenever the power supply is
plugged in. The unit also includes special circuitry to prevent the
battery from being damaged in the event of an extended power out
age. The battery should provide approximately 5 years of service
before needing replacement.

Figure 5: Battery connection

The battery is considered low at 12.0V and the Battery LED will
blink at this voltage level. If main power is less than 7.0V and the
battery voltage reaches 11V, the battery LED will go out and the
unit will go into hibernation mode (a low-power mode in which the
unit shuts down). The unit will return to its regular operating mode
when either the main power is restored or the battery voltage rises
above 11.5V. If the battery voltage continues to fall below 10.5V, the
unit will disconnect the battery to prevent deep discharge damage to
the battery. The unit will not reconnect the battery until the battery
voltage rises above 12.5V.

Grounding

Connect a #14AWG copper wire to the earth ground terminal
(marked “EG”) on the left end of the terminal strip and connect the
other end to a ground rod or metal cold water pipe (See Figure 6). It
is extremely important that the earth ground connection be as short
as possible. The ground rod should have sufficient depth to provide
a low impedance connection to earth. This connection is required
for the surge/lightning protection circuits to function properly.

27

Skymetry WTU-14 Manual

NOTE: Proper earth grounding of the Skymetry
WTU-14 is required for warranty coverage.

Ground rods can typically be found at local electrical supply houses
and/or hardware stores. You MUST contact your state “Call before
you dig” hotline at least two days before you install your ground
rod, to insure that it is safe to install the ground rod in a chosen
area.

Figure 6: Grounding the Skymetry

Wiring Sensors to Dry Contact Inputs

The WTU-14 has 8 Dry Contact inputs that can be used to moni­tor Normally Open (N.O.) or Normally Closed (N.C.) sensors. In
addition, they can also be used for pulse counting and equipment
run-time accumulation. When used for pulse count or run time
functions, the unit will count the pulse (or accumulate time) when
the input changes to the opposite of its normal state.

Dry contact sensors are wired to the terminals labeled D1 through
D8. The corresponding Ground terminals are located on the lower
level terminal strip. The input type is programmed within the
Skymetry Software.

WARNING: Do not use sensors, switches, or relays
that supply any voltage or current to the Skymetry
WTU-14.

28

Chapter 2: Installation

Figure 7: Sensor connected to a dry contact input]

Any N.O. or N.C. sensor can be attached to the WTU-14 using 18–
24 gauge wire. For distances of 1000' or more, use heavier gauge
wire. When running wire outdoors it is recommended that shielded
cable be used. Connect the shield to a good earth ground or metallic
cold water pipe. The total resistance of the circuit cannot be greater
than 100 ohms. Use wire appropriate for the application. See the
wire length recommendations, later in this chapter.

The WTU-14 may have more than one sensor connected to the same
terminal, however, the normal condition for each sensor on the same
terminal must be identical (either all N.O. or all N.C.).

Normally Closed Sensors

To wire more than one normally closed sensor on one input, they
must be connected in series. Connect a lead from the first sensor to
one of the Dry Contact Inputs on the terminal strip. Next, take the
other lead from the first sensor and connect it to one lead from the
next sensor. Continue connecting sensors end-to-end until you have
connected all of your sensors. Take the second lead from your last
sensor and connect it to the ground screw on the WTU-14 terminal
strip. See Figure 8.

Multiple N.C. inputs are typically magnetic reed switches to moni
tor the security of windows and doors.

Normally Open Sensors

To wire several normally open sensors to one Dry Contact input,
connect them in parallel. To do this, take one lead from each sen
sor and attach it one of the Dry Contact Input terminals. Then take
the second lead from each sensor and attach it to the corresponding
ground terminal. See Figure 9.
