Troubleshooting
Adding a new module in to an IED
Procedure:
1. Switch the IED off and insert the new module.
2. Switch the IED on, wait for it to start, and then perform a HW reconfig.
3. Perform a license update in PCM600.
The new module is now available in PCM600 and is ready to be configured.
Removing a module from an IED
Procedure:
1. Remove all existing configuration for the module in PCM, and write that configuration to the
IED.
2. Switch the IED off and remove the HW module.
3. Switch the IED on, wait for it to start, and then perform a HW reconfig.
4. Perform a license update in PCM 600.
Moving a module in an IED from one position to another
Procedure:
1. Remove all existing configuration for the module in PCM, and write that configuration to the
IED.
2. Switch the IED off and move the HW module.
3. Switch the IED on, wait for it to start, and then perform a HW reconfig.
4. Perform a license update in PCM600.
The new module is now available in PCM600 at the new position and is ready to be configured.
13.3 Repair instruction
164
If any configuration that makes the module needed remains, then the HW reconfig
will not remove the module.
The module will still be needed. An error indication for the module will appear, if the
module is physically removed from the IED and the IED is restarted with some part
of the configuration still requiring the module.
Never disconnect the secondary connection of a current transformer circuit
without short-circuiting the transformer's secondary winding. Operating a current
transformer with the secondary winding open will cause a massive potential build
up that may damage the transformer and may cause injuries to humans.
