DC Gearbox WeedRoller Owner's/Part Manual

OPERATION 3.2 ADJUSTING THE SWITCH ARMS During operation, the WeedRoller motor will turn the magnet mounted on the pivot tube in the direction of one of the two switch arms. The proximity sensor mounted on the arm will detect the magnet and signals the smart switch to reverse the direction of the motor. The motor will turn until the other proximity sensor detects the magnet; then the motor will reverse again. The roller tubes have a maximum arc of 270 degrees. If the switch is set for more than 270 degrees, the motor may hit the rear post weldment during operation. The magnet is positioned on the pivot tube pointing towards the rollers. Adjust the magnet right or left to achieve the desired arc. The amount of roller tube arc depends on the amount of arc between the proximity sensors mounted on the adjustable switch arms. Adjust the switch arms for desired WeedRoller arc. Position the magnet between the switch arms. Increase the arc between the switch arms for more roller arc. Decrease the amount of arc between the switch arms for less roller tube arc. LOAD REVERSE The smart switch is designed for varying conditions. Inital setting from the factory is 5.5 amp draw. The smart switch tracks the amp draw for 10 cycles (sweeps) and resets the maximum amp draw (used to reverse the motor caused by an overload conditions) automatically based on conditions. • Example: The initial setting is 5.5 (maximum) amp draw when the WeedRoller is first used. The smart switch records a 3 amp draw (highest amp draw during 10 cycles) and resets the maximum amp draw from 5.5 amp draw to 3.5 amps. (.5 amps above peak current of 3 amps). The smart switch now reverses the WeedRoller tubes if the motor draws 3.5 amps or more. The smart switch continues to monitor the amp draw and reset the maximum amp draw each 10 cycles as previously explained. RESETTING THE ELECTRONIC CONTROLLER Check for stuck roller tubes or obstructions before resetting the smart switch. See Preventing Problems Caused by Muddy Conditions on page 11 for more information on operating the WeedRoller in these conditions. Reset smart switch if adjusting the switch arms or moving the WeedRoller. Figure 11: Switch Mount Assembly PROTECTION CIRCUITRY OPERATION The smart switch has a protection circuit that monitors the WeedRoller motor current draw. During normal operation, the motor will draw about 2.0 amps. The green light on the smart switch stays lit when the WeedRoller is operating normally. The switch reverses the motor before the roller tubes complete the arc set by the switch arms if the motor draws more amps than the maximum amp draw for more than three seconds. The green light ﬂashes if the protection circuitry activates. The counter resets automatically if the roller tubes complete the arc set by the switch arms before the counter gets to six. The light ﬂashes red if the motor rotor locks or if the motor short circuits. 10 WeedRoller Owner's/Parts Manual 51285 R121411
