OVERVIEW The Tower Pivot Monitor (TPM) is an end device in the Internet of Things (IoT) for agriculture. It is installed on the electrical terminal screws of the fault alignment microswitch in the existing tower box on the center pivot used for field irrigation. It has three wire connections to the Forward, Reverse, and Neutral span cable control wires. Its job is to report position and direction of a pivot and monitor the fault alignment microswitch. It sends this information to a Gateway device. The Gateway listens for packets from end devices and periodically makes a cellular data connection to forward the accumulated end device packets to a server along with its own packets. The Gateway acknowledges packets from edge devices. The Gateway also holds downlink packets from the server for edge devices and sends them to the device after the next uplink packet from the device in lieu of an acknowledge. Tower Box Tower Box Tower Box Tower Box Tower Box Tower Box Center Pivot Tower Box Tower Pivot Monitor With a tower monitoring system installed, you can:
Tell which direction a pivot is running. Tell when it starts and stops. Tell approximately where the pivot is in the field using GPS. Tell when it has a safety stop and whether the stop was caused by alignment of the tower on which the TPM is installed. Tell when the TPMs microswitch is becoming faulty before it fails completely.*
Stop the pivot remotely, by interrupting the alignment fault detection control wire.*

This product meets the applicable FCC Part 15 rules. Operation is subject to the following two conditions:
(1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. To limit RF exposure, please ensure 8 inches (20 cm) of separation from the transmitter antennas at all times. 1.4 Installation Safety Only certified electricians should install the tower alignment monitors and tower pivot monitors. Wear appropriate safety gear. 1.4.1 Pivot Safety Read and follow your pivot manufacturers safety instructions and guidelines. Do not part a vehicle in the path of the irrigation pivot towers. Before installing the TPM on a pivot, insure that power to the pivot is off. Use a harness to tether to a solid point that could hold your weight while working up high on a pivot. Only certified electricians should install the tower alignment monitors and tower pivot monitors. 1.4.2 Ladder Safety Read and follow all safety instructions from the ladder manufacturer. Do not use a ladder under overhead power wires. Do not exceed the weight rating of the ladder. Set the ladder on s firm surface with both legs touching the ground where they will not slip or sink. Set the ladder at the proper angle. Ensure that both sides of the top of the ladder rest firmly against a solid surface Have a second person hold the base of the ladder. Keep three points of contact with the ladder. Do not overreach when working on a ladder.

The board can be damaged by static discharge. Even discharge that you cannot feel can potentially damage sensitive circuits. The TPM board should be kept in its anti-static bag until the tower box cover has been removed and it is ready to be installed on fault alignment microswitch. 1.5.2 Wiring The TPM has a pre-wired three position pluggable terminal block. The three wires connect to pivots Forward, Reverse, and Neutral span cable control wires. This is done on the tower boxs terminal block on the side opposite the span cable connections. The TPM wires are labeled. The TPMs neutral wire is white. Because of the variation in wire colors between the different pivot manufacturers the TPMs forward and reverse wires are black. Table 1 shows the various pivot manufacturer control wire colors. Control Wires Forward Reverse Neutral Alignment Fault Lindsay Pink Yellow White Brown Reinke Purple Pink White Brown Valmont Brown Orange White Yellow TPM Black (labeled) Black (labeled) White (labeled) Mounts on microswitch Table 1 Pivot Control Wire Colors 1.6 Installation Packet Series The TPM will automatically send five data packets via radio to the Gateway after it is powered up the first time by the Forward or Reverse control wires. It sends a version packet, a configuration packet, a status packet, a pivot monitor packet, and a location packet. These packets are sent with a special send-it-now flag to make the Gateway forward them immediately instead of holding them until the next normal cellular connection. The TPM turns on its GPS receiver continuously to acquire time and location. This is indicated with short cyan flashes every two seconds. It needs date and time to set its real time clock. It needs location to send the location packet. IT MUST BE ABLE TO RECEIVE FROM GPS SATELLITES TO FUNCTION CORRECTLY. After acquiring time and before location is acquired, it sends the version, status, and pivot monitor radio packets. The TPM stays on as long as the pivot is running forward or reverse. It holds enough power to send a pivot monitor and location packet after the pivot stops. 1.7 Indicator Description Since the TPM is housed in a tower box and the cover must be on the tower box to run the pivot and the pivot must be running forward or reverse for the TPM to be powered, the TPM indicator will not be visible. Indicator information is given here only for informational completeness. The TPM has a red-green-blue LED indicator to convey status. But since it is only powered up while the pivot is running, the user cannot normally see this information. The table below gives the meaning of colors and flashes.
