Summary of content (9 pages)

PAGE 1
MERLIN 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. Determine where you are going to locate both the rooftop sensors and the read-out.
PAGE 2
MERLIN TRIPOD MOUNT EVE MOUNT INSTALLATION CHIMNEY MOUNT (continued) VENT-PIPE MOUNT 8 FEET 6 Follow the instructions supplied with the antenna mount and secure the mast to the mount. WALL MOUNT 7 CABLE CLIPS Secure the wire to the building using cable clips (do not use regular WIRE staples). Form a drip loop where the wires enter the hole drilled through the exterior wall. Caulk the hole when done.
PAGE 3
MERLIN OPERATION With the switch in the center (resting) position, MERLIN will display the information indicated by the illuminated function (Present, Peak, Average, or Forecast). To select a function, move the switch to the right and allow it to return to the center. This toggles Merlin to the next function. Repeat this until you see the function that you wish. To auto-sequence through all of the functions, hold the switch to the right for at least three seconds.
PAGE 4
MERLIN OPERATION (CONTINUED) Peak Wind- When first powering up MERLIN, after long power outages, or when totally resetting, the Peak Wind direction LEDs will not function until at least 1 MPH wind has been recorded. Average Wind- The first reading after setting the Average will be the current wind speed. This reading will settle out as MERLIN accumulates more data. Prevailing wind direction lights will not function until 12 minutes after powering up or resetting.
PAGE 5
MERLIN TROUBLE SHOOTING (WIND DIRECTION) Perform the latch up corrections as previously detailed. The unit will now perform the self test, all LEDS will light for about 3 seconds. If you do not have time to check that all LEDS light, repeat the procedure. This will cause the self test to start again. If some or all of the LEDS do not light, then the fault is in the instrument. IF ALL LEDS LIGHT...... 1 Select Units of Measuret Disconnect the sensor wires from the back of the meter.
PAGE 6
MERLIN TROUBLE SHOOTING (WIND SPEED) VOLT-OHMETER Select Units of Measuret FROM AC ADAPTER AC ADAPTOR (NO POLARITY) 3 BLACK AND WHITE WIRES FROM ROOF TOP SENSORS IF THERE IS WIND...... 1 Disconnect the black and white wires from the back of the indicator and connect them to volt-ohmeter as shown. Set for low range AC Volts. 2 If the sensor is operating properly, you will achieve these approximate readings: 8-9 MPH = 0.15 VAC rms 17 MPH = 0.31 VAC rms 51 MPH = 0.97 VAC rms 102 MPH = 2.
PAGE 7
MERLIN INFORMATION FOR THE MERLIN USER Warning: Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.
PAGE 8
IMPORTANT ADDITIONAL INFORMATION Components: Along with the indicator, the following components are included with this instrument: Rooftop sensors: To insure a clear unobstructed path for the wind to the sensors, they should be mounted on some type of antenna mast at least 8-10’ above the highest object on your roof. Remember, your roof is also an obstruction and it usually requires at least 8’ of height to avoid the turbulence it creates. AC Adaptor: This instrument requires its own AC Adaptor.

Electrical Damage – Common Causes & Recommended Prevention Electrical damage can be caused by many different factors. Below are some of the more common causes and some suggested methods of minimizing potential problems. Common Causes: Storm Activity – lightening in your area can do damage to your instruments in different ways. The obvious way is due to a direct or nearby strike.
