TROUBLESHOOTING
POINT
When the standby system is powered OFF, the control system CPU module
develops in a STANDBY SYS.DOWN (error code: 6300) continuation error.
After the replacement of the standby system CPU module is complete, reset
errors in the control system CPU module as necessary.
Refer to Section 8.2 for the error resetting method.
Disconnecting the Cable
Disconnect the network cable from the target network module.
Refer to the manual of the network module, for disconnecting the network cable.
Replacing the Standby System's Network Module
1) Disconnect the network module from the main base unit.
2) Attach the replacement network module (a network module of the same type as the control
system network module).
For removal and installation of the network module, refer to the manual of the used network
module.
Wiring
Connect the network cable to the network module.
Refer to the manual of the network module, for connecting the network cable.
Turn on the Standby System's Power Supply
1) Match the position of the standby system CPU module's RUN/STOP switch with that of the
control system.
2) Set the control system CPU module's RESET/L.CLR switch to the central position
3) Turn the standby system power supply ON.
Confirm the Power Supply Module's POWER LED
Confirm that the power supply module's POWER LED is ON (green), and that power is being
supplied properly.
