Introduction

Thank you for buying Summit. These instructions are designed to take you step by step through the
process of installing and using Summit. Carefully following these instructions will help ensure many
years of trouble free service from your Summit installation. If you are uneasy about climbing a roof
and running wires you should consult a qualified professional. TV antenna, satellite dish, ham radio,
home entertainment and alarm system installers are good choices. You should be able to locate some
of these professionals in your area by consulting the yellow pages. It is always best to show prospec­tive installers these instructions and obtain quotations from a few different installers in your area.

Preparing for Installation

What you need for the installation

To install Summit you will need the following items.

Components Included with Summit Master

You may want to check off each item as you unpack the instrument.

! Indicator (readout, brass case)
! Pluggable terminal strips (one 5 position, one 3 position and, two 2 position)
! Wind speed sensor (generator)
! Wind direction sensor (distributor)
! 2 Rubber boots for wind sensors
! Temperature sensor with 100’ of 2 conductor shielded cable attached
! 100’ 8 conductor shielded cable (for wind sensors)
! 120 VAC to 24 VDC adapter with 6’ of cable
! Straight stub mast

! Hardware kit which includes:

! 2 Stainless steel cotter pins
! 10 Brass hex nuts #4-40 (there are 2 extra)
! 2 #6 pan head 1” long wood screws
! 2 Stainless steel hose clamps. These are used to secure the stub masts to the

main support mast. The included clamps are suitable for 1” to 2-1/2” diameter
main support masts. If you are using a larger diameter main support mast you
will need to obtain larger hose clamps from your local hardware store.

Components Not Included with Summit

Main support mast. See the “Choosing locations for the components” section for details.

Light oil or grease for coating the sensor terminals (e.g. WD-40, vaseline, white lithium grease)

Optional Components for Summit installations

Ice-Free wind sensor set

Summit Remote(s)

Choosing locations for the components

Wind Sensors

The higher the wind sensors are
mounted the more unobstructed
their exposure to the wind and the
more accurate their readings. We
recommend that you mount the
sensors at least 8 to 10 feet above
the highest object on the roof. TV
antenna masts and mounts are

pages). Antenna mounts are
available in a wide variety of

5 to 8 Feet

configurations, some of the more
common types are shown in the
diagram.

Temperature Sensor

Select a location for the temperature sensor that is protected from direct sunlight and clear of poten­tial physical damage. A North exposure, 5 to 8 feet above the ground is recommended (see diagram).
Keep the sensor away from sources of heat such as windows, doors and, dryer vents. Alternatively
you can mount the sensor in a properly sited meteorological instrument shelter. If neither of these
options works for your installation, a radiation shield may be the solution, please contact us for more
information.

Indicator

Summit’s large size allows it to be easily read from over 100 feet away when properly installed. For
best viewing you should avoid locations where direct sunlight will shine on the instrument. You
must also have an AC outlet near the selected location. The AC adapter supplied with Summit has a
6 foot cord. You can extended this distance by splicing on wire to the adapter. The table below gives
the maximum distances allowed for various gauges of wire.

Sensor Wires

Now that you have selected the locations for the components you should measure how much wire
you will need for the sensors. The 100 foot cables supplied are usually adequate for most installa­tions. However, you can use up to 500 feet of wire with the sensors.

If you need to, you can extend the supplied wire by splicing on extra cable or, you can buy a longer
spool of wire. The wind sensors use 24 AWG 8-conductor shielded cable and the temperature sensor
uses 24 AWG 2-conductor shielded cable.

If you splice on additional wire, you should solder the splices and, insulate them well for long term
reliability. You should make the splices and prepare the end of the wires like the 100’ wire that is
supplied before proceeding.

If you are using wire not supplied by Maximum, you should prepare the ends of the wires like the
100’ wire that is supplied before proceeding.

Installation

Trial wiring

You should do a trial wiring before running the wires through the walls. Perform the trial wiring in
the comfort of your home, garage, etc. This will ensure your confidence in the instruments’ opera­tion. If you are extending the length of any of the wires, you should do that before proceeding.

First we will wire the 8 conductor shielded cable for the wind sensors. Connect the wind sensors to
the end of the cable that has ring lugs using the brass hex nuts supplied. The 3 and 5 terminal con­nectors attach to the stripped and tinned end of the cable following the pattern shown in the diagram.
The chart below shows the wire color to sensor terminal number assignments. If you are using cable
with different wire colors you should write in the colors here and on the label on the back of the
instrument.

Attach a 2 terminal connector to the temperature sensors 2-conductor cable. The temperature sensor
wires are not polarity sensitive.

Connect a 2 terminal connector to the AC adapters 2-conductor cable. The
adapter is polarity sensitive so be sure to connect the wires as shown in the
diagram.

Configuration and Testing

We’re now ready to configure the units of measurement and test the system. First, the units of
measurement jumpers need to be set. There are six standard PC type jumpers like you find on the
circuit boards in a PC. When the jumper cap is mounted on the jumper pins, the jumper is closed, if
the cap is not mounted on the pins, the jumper is open (see diagram). The first four jumpers control
the units of measurement for wind speed, the fifth jumper sets the units of measurement for tempera­ture and, the sixth jumper sets master or remote operating mode. Summit is shipped with the jumpers
set for: Speed = MPH, Temperature = °F and Mode = Master (see diagram). The following table
shows all of the valid jumper settings. If you want to use other units of measurement then you must
change the jumper settings using the table and diagrams.

Now it’s time to plug the terminal strips into the indicator. Note that there is a plug already installed
in the space for the optional ice-free wind direction sensor, don’t remove this plug unless you are
using the optional ice-free wind sensor set (see separate ice-free sensor instructions). To plug in a
terminal, position it with the screw heads oriented toward the middle of the indicator and press into
place firmly. The connectors will snap into place when inserted correctly. Go ahead and plug the
terminals into the appropriate positions on the indicator (see diagram) The AC adapter connects to
the position labeled 24Vdc, do not plug the AC adapter into a 110VAC outlet yet.

Before we power up the instrument you need to understand the boot sequence.

When Summit is powered up it first lights up all the LED’s for 3 seconds.

Next Summit turns off all the LED’s for 2 seconds.

During this time Summit is reading the jumper settings and doing it’s POST (Power On Self Test).

The POST codes are now shown on the speed and temperature digits for 6 seconds.

The wind speed 10's digit shows whether the instrument is in master or remote mode, 0 = Remote
and 1 = Master.

The wind speed 1's digit shows the type of remote, if the instrument is a remote, 0 = Normal remote,
1 = High remote, 2 = Low remote, 4 = Chill remote.

The temperature 100's digit shows the wind sensor type, 0 = Ice Free, 1 = Standard.

The temperature 10's digit indicates the wind speed units of measurement, 7 = m/s, E = km/h, L =
Knots, P = MPH and, Blank = Beaufort.

The temperature 1's digit shows the temperature units of measurement, 0 = °F, 1 = °C

Finally Summit starts a ten second countdown for start of normal operation. The wind speed digits
count from 0 to 9 and, the temperature digits move towards the current reading, during this period.

Now plug the AC adapter into a 110VAC outlet. Check the POST codes to make sure you have
installed all jumpers correctly. Once the instrument has completed the boot sequence, the tempera­ture digits should be showing the current temperature at the sensor. Next spin the cups of the wind
speed sensor and see that a wind speed reading is shown. Finally, turn the wind direction vane and
verify that the wind direction lights change (Note - the wind direction reading only updates once per
second. If you turn the vane rapidly some LED’s will not light.). This completes the testing, unplug
the AC adapter form the 110VAC outlet and, disconnect the wires from the sensors and terminal
connectors.

Final installation

The indicator hangs on the wall from the two
hanger holes on the back. The holes will accept #10
or #8 screws and are located on 16 inch centers for
easy mounting (see diagram). Depending on the
wall material you may need to use wall anchors,
molly bolts, etc. Install the indicator mounting
screws now.

Make a hole in the wall behind the Indicator
through which all wires will be fed. CAUTION:

DO NOT MOUNT THE INDICATOR WITH
ANY WIRES UNDER ITS LIP BECAUSE OF
SHORT CIRCUIT HAZARD.

Feed the AC Adapters’ cord from the AC outlet,
through the wall to the Indicator.

Run the 8 conductor cable between the mounting location for the wind sensors and the back of the
Indicator (through the hole in the wall).

6

Mount the temperature sensor assembly with the supplied #6
wood screws as shown.

Run the cable attached to the temperature sensor from the
sensors mounting location to the back of the Indicator.

Form a drip loop with the wire that extends at least 8 inches
below the exit from the sensor and at least 8 inches below the
point of entry in the building, as shown. Anchor any exposed
wire with insulated staples or cable clips being careful to avoid
puncturing the insulation.

Mount the generator (wind speed sensor) to the straight stub
mast and secure it with a cotter pin. Mount the distributor
(wind direction sensor) on the formed stub mast (“formed” in a
lazy z shape) so that the #3 terminal lies over the horizontal mast arm
as shown (see diagram). Secure the distributor to the mast with a
cotter pin.

Slip the wind senor wires through the rubber boots. Connect the wires
to sensors like you did during the trial wiring. When completed
double check your wiring for correct number to color match up, that
the nuts are secure and, that no lugs touch one another.

Coat the brass terminals on both sensors with a light oil or grease
(e.g. WD-40, vaseline, etc.). Slide the boots onto the masts and up
around the sensor bodies.

Proceed to secure the stub masts with the sensors to the base mast using the hose clamps. Before
final tightening, turn the formed mast arm (with the distributor/vane assembly) to point true north
(see diagram). (If you use a magnetic compass, remember to allow for the magnetic declination for
your location. This information is available from your local airport.)

Secure the wires to the masts using cable ties or electrical tape so that it does not whip in the wind.

At the indicator, connect the cables to the terminal connectors. Plug the terminal connectors into the
indicator. Hang the indicator on the mounting screws.

Plug the AC Adaptor into the 110 VAC outlet. Verify that the POST codes are correct. This com­pletes the installation of Summit.

Symptom Things to check

LED’s do not light. AC Adapter wiring.

AC adapter power, 24 to 28 VDC.
AC outlet power, 110 to 120VAC.
Indicator fuse.

Fuses keep blowing. AC Adapter wiring.

No wind speed reading. Wind speed sensor wiring.

Field Test: Disconnect the wind speed sensor wires
from the terminal connector. Using a jumper wire (a
paper clip will do), momentarily make a short circuit
between terminals #7 and 8, a few times per second.
You should get a reading on the wind speed display. If

it does read this new value then the problem is either a
problem in the wires or a defective sensor.

No wind direction reading. Wind direction sensor wiring.

Field Test: Unplug the AC adapter from the AC outlet.
Disconnect the wind direction sensor wires from the
terminal connector. Connect a jumper wire (a paper clip
will do), between terminals #1 and 3. Plug the AC
adpater back into the AC outlet. Watch the POST code
to make sure it indicates standard wind sensors (tem­perature 100's digit = 1). If the POST code shows 0
(ice-free sensors) then the problem is in the indicator. If
the POST code is correct, wait for the instrument to
finish the boot sequence. You should get a reading of
NNE on the wind direction display. Next test the other
directions by moving the jumper wire to the following
positions. 2 to 3 = ESE, 4 to 3 = SSW, 5 to 3 = WNW.
If it does read these wind directions then the problem is
either in the wires or a defective sensor.

Temperature always reads -40°. Temperature Sensor wires

Field Test: Disconnect the temperature sensor wires
from the terminal connector. Connect a jumper wire (a
paper clip will do) to the terminal connector. Plug the
terminal connector into the indicator. The temperature
should slowly climb to 122°F (50°C). If it does read
this new value then the problem is either an open circuit
in the wires or a defective sensor.

Temperature always reads 122°F (50°C). Temperature Sensor wires

Field Test: Disconnect the temperature sensor wires
from the terminal connector. The temperature should
slowly drop to -40°. If it does read this new value then
the problem is either a short circuit in the wires or a
defective sensor.

The m/s units for wind speed won’t work even though the jumpers are set correctly.

Make sure that there is a terminal connector installed in
the ice-free direction terminals and, that the connector
has a jumper wire connecting terminals #1 and 2.

Appendix C Common Questions and Answers

Q What are the two push button switches for?

A The two push button switches are only used with remotes that calculate Highs, Lows or

Averages. They are used on the remotes for setting the time of the built-in clock. See the
seperate remote instructions for details.
