SOLENOID TRANSIENT VARIABLE RESISTANCE FEEDBACK FOR EFFECTER POSITION DETECTION |
摘要 |
Feedback from a solenoid is achieved by adding at least one variable resistance in parallel with the solenoid current feedback circuit for position detection. The resistance has current flowing therethrough when a switching device actuated by the solenoid is in one position or transitions from one position to at least one other position. A feedback current may be measured in the current feedback circuit and the position of the switching device in response to actuation thereof by the solenoid may be determined from the measured feedback current. |
