CONTROLLER OF ROTARY SWITCH

摘要

A controller of a rotary switch receives, via a contact receiver, signals from a plurality of fixed contacts of a rotary switch that rotates a movable contact to connect the movable contact to any of the fixed contacts, and outputs a command based on the received signals. The controller of the rotary switch monitors a transition of an output code received from the contact receiver, and determines that a failure has occurred in the rotary switch when the transition of the output code does not match a transition pattern of the output code of the case where the rotary switch operates normally.

1. A controller of a rotary switch that receives, via a contact receiver, signals from a plurality of fixed contacts of a rotary switch that rotates a movable contact to connect the movable contact to any of the fixed contacts, and outputs a command based on an output code of the rotary switch formed of the received signals, comprising:
a failure detection unit configured to monitor a transition of the output code received from the contact receiver, and determines that a failure has occurred in the rotary switch when the failure detection unit detects the transition that does not match a transition pattern of the output code of a case where the rotary switch operates normally.
