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 (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. DIP switch
settings select the units (mph or kph) and enable/disable the buzzer.
Each alarm channel has three programmable settings:
Delay before Alarm 0-99 seconds above threshold before alarm activation (Default 15 sec)
Alarm Set Point Wind speed threshold for the alarm (Default 15 mph)
Delay after Alarm 0-99 seconds below threshold before alarm de-activation (Default 15 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 TECHNICAL SPECIFICATION
The anemometer is rated for wind speeds up to 125 miles per hour and has a starting threshold of
approximately 1.2 mile per hour. The Wind Alarm LCD can display speeds up to 99.9 mph, but the
control logic continues to operate above this limit.
The controller requires a nominal 12V ac or dc power supply. The 200-WS21P power pack (sold
separately) is suitable in most applications, and comes with the proper terminals for easy connection.

4 PRE-INSTALLATION CHECKOUT
The controller can be operated before installation to become familiar with the menus and programming
features. You will need a power supply and the Wind Alarm controller. The sensor and relays will not be
connected for these tests.

NovaLynx Corporation________________________________________________________________________________
200-WS-21-A Page 6 November 2018
4.1 Power Supply Connection
The 200-WS-21P power supply (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, use the provided accessory connectors to wire to your 12V
ac or dc power source. Plug the AC Adapter into a wall outlet and
check that 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.
4.2 Menu Navigation

4.4 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. It is
necessary to disconnect the AC Adapter for a few seconds and then re-connect power for the unit to
change modes.
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.
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: Always 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 often mounted to the top of the supporting mast. A mounting arm
(Part number 200-153) is available for mounting to the side of the mast or tower. 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.
The mast should be easy to reach for servicing the sensor and should be properly anchored and
grounded. A tilt-down arrangement can eliminate the need for lifts or ladders during installation and
service.
If the supporting mast or tower is metal it should be properly grounded to minimize lightning damage.
Installations where nearby lightning strikes are likely should include a properly grounded lightning rod

NovaLynx Corporation________________________________________________________________________________
200-WS-21-A Page 9 November 2018
above the level of the sensor, preferably on a separate tower. It may be necessary in some locations to
contact a local contractor to ensure that local electrical codes have been met by the installer.
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. Tighten the screws until the sensor base can no longer be manually rotated.
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. Avoid sharp bends, excessive twisting, scrapes and nicks.

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.
Therefore 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.

NovaLynx Corporation________________________________________________________________________________
200-WS-21-A Page 10 November 2018
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 short spray of light oil such as
WD40 can be applied to the bearing located in the hub of the cup assembly.
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.
6.2 Controller Mounting
There are 4 knock-out locations inside the controller box for placing screws. It will be necessary to remove
the controller to access these points. After mounting the case to your wall or panel, use the provided caps
to cover the screw locations. This will help keep moisture from entering the box. Replace the controller
circuit board and secure it with the mounting screws.

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. Stranded wire of 14 – 16 gage 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.
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
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.
We recommend 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.
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, before connecting the relays to your external equipment. Recheck 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 12 November 2018
7.3 Relay Connections
There are two relays for connection of external alarms or to operate/disable pumps, etc. Please refer to
the specifications to ensure the relays are rated for the load you intend to control. If the contact rating is
less than required an external contactor may be required. 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 contacts are "dry". Connect the hot lead to C1 for relay #1 or to C2 for relay #2. The N.O. or N.C. is
then connected to the load, and the neutral of the load completes the circuit.
Notice 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 if there is any chance that someone might put their
fingers on 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.
