A method of detecting a single point of failure includes: placing a portion of a machine being monitored by a plurality of monitoring devices in a first position; causing the portion to cycle to a second position during a first cycle; measuring a component of electrical power provided by a first power supply unit while the portion cycles during the first cycle; returning the portion to the first position; causing the portion to cycle to the second position during a second cycle; measuring the component of electrical power provided by a second power supply during the second cycle; determining that an amount of the component of electrical power provided during either the first or second cycle is equal to or less than a minimum value; and generating an alarm.
