WIND ALARM

OPERATION / INSTALLATION INSTRUCTIONS

Thank you for purchasing the Maximum wind speed alarm system. The Maximum
wind speed alarm system is a dual set point digital instrument. It contains a yellow
light to display one set point, a red light to display the other set point. When both
alarms activate an audible buzzer will turn on. Each set point controls a SPDT relay
(rated at 5A at 30VDC), that can be used to turn on or off many devices.

*** IMPORTANT ***
This instrument is to be used as an aide to your current safety
program, and is not to be used exclusively in operations that may
affect personal and/or property safety.

Installation
Proper Installation is important. If you need assistance, consult a

contractor electrician, or television antenna installer (check with
your local building supply, or hardware store for referrals). To
promote confidence, perform a trial wiring before installation.

1. Determine where you are going to locate both the rooftop sensor and the read-

out.

2. Feed the terminal end of the three-conductor cable through the bottom of the

enclosed rubber boot and connect the lugs to the terminals on the bottom of the
wind speed sensor. Wire the clear wire to number 6 on the generator, black
wire to number 7 on the generator, green wire to number 8 on the generator.
(Do not adjust the nuts that are already on the sensor).

3. Slide the stub mast through the rubber boot and insert the stub mast into the

bottom of the wind speed sensor. Secure with the cotter pin. Coat all

connections with silicone sealant and slip boot over the sensor.

4. Secure the sensor and the stub mast to your antenna mast (not supplied) with

the two hose clamps. Radio Shack and similar stores have a selection of
antenna masts and roof mounting brackets. Choose a mount that best suits your
location and provides at least 8 feet of vertical clearance above objects on the
roof.

5. Follow the instructions supplied with the antenna mount and secure the mast to

the mount.

6. Secure the wire to the building using cable clips (do not use regular staples).

7. Feed the cable through the wall to where the read-out is going to be located.

8. Remove Clear Cover. Remove the circuit board from the plastic enclosure by

removing the screws on each corner. Tilt the enclosure forward until the circuit
board pops out.

9. Remove the outside nut from the base of the enclosure. Feed the sensor and

power wires through the nut. Then, into the enclosure of the instrument through
the opening. Do not power the instrument yet.

10. Connect the wires to the circuit board terminal strips. Connect the green sensor

wire to terminal marked # 1. Connect the black sensor wire to terminal marked #

2. Connect white (clear) sensor wire to terminal marked # 3.

11. Connect the negative power wire to terminal marked # 4. Connect the

positive power wire to terminal marked # 5. Note: Use only a 9 – 15 VDC
power source.

12. Place circuit board back into the enclosure. (You may need to pull back on the

wires while you are trying to place circuit board back into the enclosure. It may
also help to place the connector side in first then the top of the circuit board).
Replace the screws to secure the circuit board. Re-attach the nut to the base of
the enclosure. Nut should be in tight as it acts as strain relief for the cables and
protection from moisture.

13. Apply power to the instrument and check operation.

OPERATION

The thumbwheel switch right below each LED controls the yellow or red warning
light. Adjust the speed that you want to set off the yellow or red light by pushing the
adjustment lever on the thumbwheel switch to the desired wind speed. Once the
wind speed reaches the level set on the thumbwheel switch the yellow or red light will
turn on and activate the relay. When both lights are activated, the buzzer will sound.

The relays are SPDT. If you are looking right at the relay terminal block, the yellow
light controls terminals 6, 7, and 8. With the alarm off 7 and 8 are normally closed
and 6 and 8 are normally open. The red light controls terminals 9, 10, and 11. With
the alarm off terminals, 10 and 11 are normally closed and terminals 9 and 11 are
normally open.
