Explanation of function and operation
1. 16-bit operation (ANR and ANRP)
When the command input turns ON, a state relay working as annunciator (S900 to S999) in the ON status is reset.
• If two or more state relays are ON, the state relay with the smallest number is reset.
• If two or more state relays are ON, the state relay with the smallest number is reset.
When the command input is set to ON again, the state relay with the next smallest number is reset among state
relays working as annunciators (S900 to S999) in the ON status.
relays working as annunciators (S900 to S999) in the ON status.
