Using the unattended start protection and the Start Check Function
in Combination
• When used in combination with the start check function (3008Hex-61Hex = -61, 2), a run operation
error (alarm code: 24, sub code: 5) is generated by the start check function, and this is given priority.
For this reason, to cancel the run operation error, turn the RUN command OFF and then perform a
reset operation.
• For details on the start check function, refer to 8-7-3 Start Check Function on page 8-69.
