Abstract
Methods and apparatus for monitoring solenoid valve health are disclosed. A switchbox includes a state manager, a position detector, and a notification generator. The state manager changes an activation state of a solenoid valve between a first state and a second state in response to an initiation signal of a solenoid valve test. The position detector determines, based on position data obtained at the switchbox from an integrated position sensor of the solenoid valve, whether a core of the solenoid valve has moved by at least a threshold change in position within a predetermined time period following the change of the activation state of the solenoid valve. The notification generator generates a notification in response to the position detector determining that the core did not move by at least the threshold change in position within the predetermined time period. The notification indicates that the solenoid valve failed the solenoid valve test.
