Methods and systems for determining the status of a solenoid. A method includes measuring a plurality of parameters associated with a current conducting through the solenoid. The measured parameters are compared to predetermined reference parameters to determine the status of the solenoid. A system includes a sensor configured to measure a plurality of parameters associated with a current conducting through the solenoid. The system includes a control module configured to receive the measured parameters and operable to compare the measured parameters to predetermined reference parameters to determine the status of the solenoid.

Solenoid status determination methods and systems

Communications systems and methods for transmitting extendible conveyor control signals along an extendible conveyor. A conveyor communication system includes a first transceiver for use on a stationary boom of an extendible conveyor system, configured to communicate with a conveyor main control of the extendible conveyor system. The conveyor communication system includes a second transceiver for use at an end boom of the extendible conveyor system, configured to communicate with a control station on the end boom. The second transceiver is configured to receive wireless communications from the first transceiver over a wireless communications link.
