1 FORWARD
Thank you for purchasing NovaLynx products. NovaLynx has been designing and manufacturing
weather instruments since 1988. NovaLynx represents several well-known brands of quality
manufacturers, including Gill Instruments, RM Young, Kipp & Zonen, and Vaisala. It is our hope that our
products will meet all your monitoring requirements.
2 INTRODUCTION
The 200-WS-21-A Dual Set Point Wind Alarm includes a rotating cup style anemometer (NovaLynx
200-WS-01B) and internal alarm buzzer. Two independently controlled relays are provided to operate
external equipment such alarm lights or sirens. The Wind Alarm can function as an irrigation or
fountain over-ride controller.
The back-lit LCD display is easily visible through the transparent cover. With the cover removed the
unit is programmed by push-button controls without the need to connect a computer. All set points
and the maximum wind speed value are stored in non-volatile memory. DIP switch settings select the
units (mph or kph) and enable/disable the buzzer.
Programmable Features:
Alarm Set Point Wind speed threshold for the alarm
Channel 1 0-100 mph or 0-160 kph (Default 25 mph / 40 kph)
Channel 2 0-100 mph or 0-160 kph (Default 50 mph / 80 kph)
Alarm ON Delay 0-99 seconds before alarm/ relay activation (Default 5 sec)
Alarm OFF Delay 0-99 seconds before alarm / relay de-activation (Default 5 sec)
When in alarm mode, a blinking LED indicates which relay(s) are active. Each relay can be connected in
the normally open or the normally closed mode. It is the responsibility of the installer to properly
insulate any connections to the relay terminals, especially if high voltages are present. It is also
important to provide an earth grounding wire to protect the controller from static discharge,
whether or not the relays are connected.
3 SPECIFICATIONS
The anemometer is rated for wind speeds up to 125 miles per hour (201 kph) and has a starting
threshold of approximately 1.2 mile per hour (2.0 kph). The Wind Alarm LCD can display speeds up to
99.9 (mph or kph), but the control logic continues to operate above this limit.

NovaLynx Corporation________________________________________________________________________________
200-WS-21-A Page 5 February 2021
The controller requires a 12V AC or DC power supply. The NovaLynx 200-WS21P Power Pack (sold
separately) is suitable in most applications, and comes with the proper terminals for easy connection.
4 PRE-INSTALLATION CHECKOUT

4.1 Power Supply Connection
The 200-WS-21P Power Pack (sold separately) is provided with ¼"
spade connectors that fit the terminals at the lower left corner of
the Wind Alarm circuit board. If you are using a different power
supply, crimp the provided accessory connectors to your 12V AC
or DC power source. Plug the AC Adapter into a wall outlet and
confirm the green power LED on the Wind Alarm circuit board
turns on.
The display should look similar to the
illustration on the right. This is the
operating mode screen.
NOTE: If you see the word "Temp:"
instead of "Wind:" then the DIP
switches are in the wrong position.
Refer to the "DIP Switch Settings"
section of the manual to correct this
situation.

4.5 DIP Switch Settings
The DIP switches are pre-set at the factory and should not need to be adjusted. However, sometimes
during installation they get changed accidentally.
1. The Dual Set Point controller is designed to operate as either a wind alarm or temperature
alarm. The DIP switch marked "Wt" determines which mode is selected. Set this switch to OFF
for wind alarms.
2. Set the "Wu" switch to OFF for wind speed in miles per hour (MPH). Set the switch ON for
kilometers per hour (KPH).
3. The "Tu" switch sets the temperature units. This is not relevant to the wind alarms, so it doesn't
matter how this switch is set.
4. The "Si" (silent) switch determines whether the internal buzzer operates. The normal setting is
OFF which allows the buzzer to operate. The ON setting silences the buzzer.
The controller checks the positions of the DIP switches when the unit initializes during power-up.
Disconnect the AC Adapter for a few seconds and then re-connect power to change modes after
changing any switches.
5 ANEMOMETER INSTALLATION
WARNING: Avoid overhead power lines whenever possible. If there are overhead power lines, use
extreme care to prevent contact with the power lines while installing the equipment. NovaLynx
recommends using only experienced equipment installers to avoid injury.
5.1 Anemometer Siting Considerations
Choose a mounting location for the wind sensor that is free of obstructions since nearby objects can
create eddy currents that will affect the wind measurements. Try to locate the wind sensor so that the
nearest object is 10 x T away from the wind sensor mast, where T is the height of the object.

NovaLynx Corporation________________________________________________________________________________
200-WS-21-A Page 9 February 2021
Roof mounted sensors should be placed on the upwind side of the building and away from all exhaust
vents. If the sensor is located on top of a building the sensor height should be 1.5 x H, where H is the
height of the building.
In all cases when the wind sensor data is to be correlated to National Weather Service data or World
Meteorological Organization data, the standard exposure is 33 feet (10 meters) above the ground.
5.2 Anemometer Mounting
CAUTION: Be careful when working on equipment that is mounted above you. Do not allow others to
stand below when equipment is being installed as falling objects can be hazardous.
The 200-WS-01B anemometer is usually mounted at the top of a supporting mast. The base of the
sensor accepts ¾" IPS pipe size or any other 1" to 1-1/16" (25 to 27 mm) outside diameter pipe. If the
anemometer cannot be mounted at the top of a mast, the NovaLynx 200-153 Mounting Arm (sold
separately) can be used to mount the sensor to the side.
The supporting mast or tower should be properly grounded to minimize lightning damage. Where
lightning strikes are likely a lightning rod above the level of the sensor, preferably on a separate tower,
should be installed.
Position the wind sensor onto the end of the mast or mounting arm. Secure the sensor to the mast
using the set screws provided in the sensor base. Do not use excessive force when tightening the
screws.
5.3 Cable Installation
The PVC jacket of the cable will last for many years outdoors under normal circumstances. In harsh
environments it may be necessary to protect the cable with conduit.
Route the sensor cable down the mast and to the monitoring equipment in the most direct manner.
Leave a "drip loop" of cable below the entry point to the equipment enclosure to help keep moisture
out. Fasten the cable to the mast with cable ties to prevent whipping during high velocity winds. For
best results, use plastic cable ties that are resistant to ultra-violet radiation and place them at two foot
intervals. Do not over-tighten.

Wire Diagram for 200-WS-01B Wind Speed Sensor
NOTE: The shield wire in the sensor cable is electrically connected to the shaft holding the bearing /
cup assembly. The purpose is to bleed off static that would otherwise affect the sensor output. It is
important to earth ground the shield wire for best results.
5.5 Anemometer Maintenance
Wind sensors experience vibration due to high velocity wind. The vibration can loosen the mounting
screws or the support structure. Regular inspection of the mounting hardware is required to prevent
damage to the sensor.
1. Tighten the mounting screws if necessary (do not strip the threads in the plastic base of the
sensor).
2. Spin the anemometer cup assembly. It should turn freely. A drop of light machine oil (e.g.
fishing reel oil) may be applied when needed. Do not use penetrating oil such as WD40 because
it will wear off quickly leaving the bearing dry and susceptible to rust.
3. Inspect the cable and ensure it is secured to the mast to prevent damage due to wind whipping.
4. A repair kit (Part number 2502-14-10B) is available in case one of the cup arms is broken.
6 WIND ALARM CONTROLLER INSTALLATION
6.1 Controller Location
To be effective the Wind Alarm controller must be in a location where one can view the display and hear
the alarm. At the same time it should not be accessible to unauthorized personnel. It will need to be
mounted near a 120VAC receptacle for power. If the controller is inside a building the sensor cable will
need to be routed outside so that the sensor can be exposed to the wind.

NovaLynx Corporation________________________________________________________________________________
200-WS-21-A Page 11 February 2021
6.2 Controller Mounting
There are 4 knock-out locations inside the controller box for placing screws. It will be necessary to remove
the circuit board to access these points. After mounting the case to your wall or panel, install the small
caps that are included in the accessory bag to cover the screw locations. The caps will help keep moisture
from entering the box. Replace the controller circuit board and secure it with the mounting screws.

NovaLynx Corporation________________________________________________________________________________
200-WS-21-A Page 12 February 2021
7 CONNECTIONS
Please refer to the connection diagram in Appendix A of this manual.
The anemometer and AC adapter (200-WS-21P, sold separately) are supplied with connectors that fit
the ¼" spade terminals on the Wind Alarm circuit board. Extra connectors are provided for connecting
an earth ground and alarm relay connections. You will need a crimp tool or heavy duty pliers to make
these connections. You will also need to provide insulated wire for the earth ground and relay
connections. Stranded wire (14 to 16 AWG) is preferred.
Standard Wire Wire Connector with an
Connector extra lug for Earth Ground
7.1 Anemometer Connection
Route the anemometer cable through the gland fitting and into the case. Connect the earth ground
connector with the tab facing down, to make room for the other connections. Attach the red and black
wires as indicated on the drawing (Appendix A).
Prepare a suitable length wire with a standard wire connector, and connect it to the lug on the earth
ground connector. Route the other end of this wire to a good earth ground – an electrical box with an
earth connection or a metal cold water pipe that actually enters the ground. Failure to provide a ground
may cause erratic operation and make the system more vulnerable to damage from nearby lightning
strikes.
7.2 Power Connection
NOTE: It is good practice to program the set points and delays, and then operate the system using the
visible LEDs and buzzer as alarm indicators for testing the system before connecting the relays to your
external equipment.
Route the wiring from the AC Adapter or other power supply through the cable gland and attach the
positive terminal (marked with red shrink wrap or a white stripe on one lead) to the ACin / DCin
terminal. Connect the ground wire to the ACin / DCgnd terminal. The power input accepts 12 volts AC
or DC.
NovaLynx recommends connecting the AC Adapter to an outlet with a surge suppressor. Power strips
with surge suppressors are often used to protect computer equipment and are readily available.
Check your connections to make sure there are no stray wires that could cause a short circuit. Plug in
your power supply. The green power LED should turn on and the word "Wind:" will be displayed. If you
see the word " Temp:" instead of "Wind:" then the DIP switches are in the wrong position. Refer to the
"DIP Switch Settings" section of the manual to correct this situation.

NovaLynx Corporation________________________________________________________________________________
200-WS-21-A Page 13 February 2021
7.3 Relay Connections
There are two internal relays for alarms or operating pumps, etc. Please refer to the specifications to
ensure the internal relays are rated for the load you intend to control. If the contact rating is less than
required an external relay will be needed (not supplied). Refer the installation to a qualified electrical
contractor.
WARNING: Turn off all power sources before connecting to the relays. Identify which relay(s) you will
be using and which function is required. When there is no alarm, the N.O. contacts are OPEN. This
contact is used to turn something ON when there is an alarm. The N.C. contact does the opposite, i.e.
turns something OFF when there is an alarm.
The relay contacts are "dry". Connect the Hot lead to C1 for relay #1 or to C2 for relay #2. Connect the
corresponding N.O. or N.C. output to the load. The return side of the load must be connected to
Neutral to complete the circuit. Connect the grounding wire to the Earth Ground lug.
WARNING: The unused spade lug (N.O. or N.C.) will be electrically HOT under some circumstances.
Place a spare connector or insulating tape over the unused lug to prevent anyone from touching it
accidentally.
Be sure you have programmed the Wind Alarm to the settings you desire and the system is operating
properly before you connect power to your external devices.
8 ALARM FUNCTIONS
The Wind Alarm controller must be in Operating Mode in order for the alarms
to activate. Alarms are disabled while programming and when the unit is in
Paused Mode. Be sure to return the unit to Operating Mode when the alarm
function is required. (See GO button instructions). Operating Mode Screen
Alarm Channel #1:
The audible alarm will beep at 400 millisecond intervals (if enabled) and the relay will energize when
the threshold and Delay-Before-ON timeout has occurred. A red LED on the circuit board will also flash.
Alarm Channel #2:
The audible alarm will beep at 200 millisecond intervals (if enabled) and the relay will energize when
the threshold and Delay-Before-ON timeout has occurred. A red LED on the circuit board will also flash.
When both alarms occur together, the beeping will be at 200 millisecond intervals.
Paused Mode
Press the GO button to place the controller in Paused Mode to turn off the alarms and relays. The
controller will remain in this mode indefinitely unless the power to the controller is interrupted. Press
GO again to return to operating mode.
CLEAR Button (temporarily clears the alarm)
The CLEAR button will stop the alarms by clearing the Delay Before ON timeout. If the wind speed is
higher than the threshold the alarm will activate again when the timeout occurs.
