Overview

Thank you for purchasing the MAC3 wind speed alarm and controller. This
manual is designed to lead you through a step-by-step process to install and operate the MAC
Note: If this unit is being used as an ALARM, it is to be used as an aide to your current safety program, and it is not to be used exclusively in operations that may affect personal and/or property safety. Please do not use the time delay feature when using the instrument as a wind speed alarm.
It is advisable to bench test your MAC3prior to final installation.
3 properly. Please read thoroughly prior to installation.

Installation

PROPER INSTALLATION IS IMPORTANT. IF YOU NEED ASSISTANCE, CONSULT A CONTRACTOR, ELECTRICIAN, TELEVISION ANTENNA INSTALLER, OR HOME ELECTRONICS SPECIALIST. CHECK LOCAL BUILDING CODES PRIOR TO INSTALLATION.
1. Determine where the MAC3
speed sensor(s) will be located.
A. Feed the terminal lug end of the shielded wind
speed cable through the bottom of the enclosed rubber boot and connect the lugs to the terminals on the bottom of the wind speed sensor (no polarity) using the supplied 4-40 nuts in the hardware bag. Do not adjust the nuts that are already on the sensor.

B. Slide the stub mast through the rubber boot and insert
the stub mast into the bottom of the wind speed sensor. Secure the sensor to the mast using the cotter pin supplied in the hardware bag. Coat all wire connections with a rubber silicone sealant and slip the boot over the sensor.
Page 5

C. Secure the sensor and the stub mast to your antenna mast (not
supplied, but available) with the two hose clamps supplied in the hardware bag. Choose a mount that best suits your location and provides at least eight feet of vertical clearance.
D. Follow the instructions suplied with the antenna mount (not
included, but available). Secure the wire to the building or structure using proper cable clips (not included).

E. Wire the included MAC3 power/sensor shielded cable to the
terminal strip supplied in the hardware bag. Terminal strip is marked 1-6, where:
1 = Red = +12VDC/24VDC 2 = Black = Common from Power Supply 3 = White = Sensor 1 (no polarity) 4 = Green = Sensor 1 (no polarity) 5 = Orange = Sensor 2 (optional, no polarity) 6 = Blue = Sensor 2 (optional no polarity)

F. Attach the MAC3 power/sensor shielded cable to the left socket and
twist the cap to lock it in place.
G. Apply proper voltage (12VDC to
24VDC) to terminals 1 and 2 of the terminal strip. Follow screen prompts on the MAC3 (see operating
instructions).

H. Secure MAC3 indicator in a proper mounting location using the
screws supplied in the hardware bag. Secure the terminal strip with the screws supplied in the hardware bag to ensure the wire connections are stable. The MAC
3 indicator and anemometer are
weather-tight to the IP65 standard and are rated for use from -40°F to 158°F (-40°C to 70°C).

The MAC3 Wind Speed Alarm & Controller can be used in various
configurations.
program, it should only be used in either the NORMAL ALARM or LATCHING OUTPUTS mode. The RANGE ALARM and TIME DELAY OUTPUT modes are suitable when the MAC3 is being used as a controlling device only.
1. Normal Alarm: Use this feature to customize the Set-Points of the MAC3.
In NORMAL ALARM mode, the alarm and relay Set-Point will activate when the wind speed reaches the Set-Point value. The alarm and relay will deactivate when the wind speed drops below the same Set-Point.

Troubleshooting

Please note, the operating temperature of the MAC3 is -40°C (-40°F) to -70°C
(158°F). The MAC
reaching these temperatures, the screen will show a warning to alert the user.
1. No Display: Check to make sure that the power supply is connected and
verify its rated output with a multi-meter. If still no display, unplug the power cord from the MAC
a. When the ambient temperature is close to an operating limit, the
MAC

-22°F /-30°C or greater than +140°F/+60°C, warm or cool the MAC
and then re-try powering up.

2. Sensor/Cable failure: If the wind speed display changes to “CONTINUITY
TEST FAILURE HIGH RESISTANCE”, or “HIGH OHMS” in 2-sensor operation, check to ensure that there are no breaks in the cable. To test the sensor, disconnect the cable and, using a multi-meter, measure the resistance across the terminals of the sensor. If the sensor is good it will show aprroximately 700 ohms.
3. Change Lock Code Screen: If the entered old code is wrong, then the
screen values are all reset to zero and the first digit of the old code value is re-selected.
