| When LT Series is powered up and the system is
booted, the relay of the alarm output circuit turns ON. When
a major error or watchdog error occurs, this relay switch turns
OFF. An external fail-safe circuit can be provided to monitor
this relay output. |
 |
Note: This relay switch is OFF from the time the power is turned
on until the LT Series system is booted. The external monitoring
circuit must be started after the LT Series system is booted. |
