The Tracker IPm wind speed setup will accept pulse or 4-20mA inputs from any commercially available anemometer. You can set it up in m/s or mph as long as you keep the engineering units the same for all the variables ie: meters/sec or mph.
Wind Speed Thresholds
There are 2 wind speed thresholds for each axis found in tab F IN.
- The lower threshold variable is WIND_HIGH in m/s or mph.
- The higher threshold variable is WIND_HIHI in m/s or mph.
You must decide what position in degrees you want the motors to go when each of the thresholds are reached.
- The lower threshold position variable is WIND_H_ALT for the Altitude motor or WIND_H_AZ for the Azimuth motor found in tab F IN.
- The higher threshold position variable is WIND_HH_ALT for the Altitude motor or WIND_HH_AZ for the Azimuth motor found in tab F IN.
- If the values for WIND_H_AZ and WIND_HH_AZ are zero then the azimuth drive will not got into protection mode. Altitude on the other hand will go to zero degrees elevation.
On a blustery day and the wind reaches the preset threshold momentarily, it would not make sense for the tracking motor to go in and out of protection mode. The Tracker IPm uses configurable dead bands and timers to put the tracker into protection mode and leave it until the inclement weather passes.
Alarm Delay Timer
This timer requires the program wait for the respective threshold to be met for the specified time before protection mode is enacted.
- WIND_ALMDELAY is configured in milliseconds ie 5000 = 5 seconds found in tab L IN.
Once the WIND_HIGH speed has been met for the required time, the variable WIND_ALMDB (found in tab F IN) provides a dead band value in m/s or mph that keeps the Tracker in protection mode even though the wind speed has dropped below the WIND_HIGH threshold.
For example say your WIND_HIGH threshold is set at 30 mph and your WIND_ALMDB is set for 5 mph. The unit will go into HIGH protection mode when the wind reaches 30 mph (for the allotted seconds) and will remain in alarm until the wind speed drops below (30-5) 25 mph.
There are 2 dwell timer setting in seconds which determine how long the tracker will stay in protection mode after the wind has returned to an acceptable level.
- WIND_H_DWELL for High threshold in seconds found in tab L IN.
- WIND_HH_DWELL for High-High threshold in seconds found in tab L IN.
You can utilize the analog input as a primary or secondary wind speed input. The Tracker IPm will take the higher of the two inputs and execute the protection algorithm.
Secondly you can use the analog input with a handheld test meter to test your configuration in case there is no wind
Refer to the wiring diagram for the proper wire locations on the Tracker IPm.
If your anemometer utilizes a reed switch, then this is a two wire set up. Simply connect one wire to terminal 17 (+) and the other to terminal 34.
For a Hall input this requires a three wire set up with the 3rd wire connected to terminal 18 (-). A pull up resistor may be required so check the manufacturer’s installation instructions for a 24VDC system.
Tracker IPm now offers another way to calibration your tracker without a PC by using manual control switches. If you wish to use external switches for manual control and calibration, this is an easy way to do so. Since the switches are connected to low voltage (24VDC) signal terminal, micro toggle switches can be used. Use 3 position toggle switches which are Normally Open – OFF – Normally Open. Toggle type is preferable to momentary.
The Auto / Manual switch required to operate the Tracker IPm is included here. This is a two position SPST toggle switch.
Note Tracker IPms running on software version 1026 / 2026 / 3026 and above allow calibration of the tracker using only the toggle switches.
Enabling Calibration Utilizing Manual Switches
Operations / Test I/O
Select Tab D OUT
With Auto/Manual switch set in Auto, simply move one axis at a time in the desired direction. Hold the switch in place for short periods to bring the tracker into position. Holding it down too long may cause the tracker to over shoot. The user may leave MANUAL_CAL ON or turn off to prevent unauthorized local changes to calibration.
With Auto/Manual in the Manual position, each switch will move the tracker in the desired direction temporarily but go back to its current tracking position when put back into Auto.

Once the software loads, it should connect to the Web in a few minutes. If after 4 or 5 minutes it still does not connect, cycle power and then check your Internet connection. This is done by plugging your lap top into the same Ethernet port on the network that the Tracker IPm will use. Open a standard browser and confirm you are able to surf the Web. Make sure your WiFi connection is off. If a connection cannot be made, contact your network administrator.
