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.

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.
Wind: 0.0 (mph)
1: 25 2: 50
