Pivots use conductor span cable to carry electricity from the pivot panel,through the collector ring, through each tower box and ultimately to the Last Regular Drive Unit. The cable contains wires for both power (480 VAC) and control (120 VAC) circuits. Wires within the cable are color-coded to designate the function of each wire.





The safety circuit is the most important circuit on the pivot. It ensures that the pivot runs safely and will shut down the machine if it’s not operating correctly. This series circuit runs from the control panel, out through each tower box to the end of the machine and back again. If anything along the way goes wrong, the machine will shut down, reducing the chance of crashes and/or structural damage to the machine.





Irritech tower boxes use Honeywell micro switches, Schneider contactors and UL Recognized terminal blocks. We have designed and developed an indicator light underneath the tower box which will provide an instant visual alert if there is a break in the safety circuit. You also can scan the QR codes printed on our tower box and panel to find the trouble shooting videos and documents.
