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.

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.
