2. Turn the power off once, connect the Controller Link Network and turn the
power on again. Check that the Unit is participating in the Network.
If the INS indicator is lit and the ERC and ERH indicators are off, then the
Unit is in the Network.
3. Return the Polled node/polling node setting of the node in which the Unit
was replaced to “polling node.” For C200HX/HG/HE and CQM1H-series
Controller Link Units, the EEPROM Clear bit will already be set to not clear
EEPROM.

4. Restart the Controller Link Unit or turn the power off and then back on
again, and then check to see if the Unit is participating in the Network.
If the INS indicator is lit and the ERC and ERH indicators are not lit, then
