Method
1. If possible, make sure that there is enough power available for the system. That is, are there enough
gensets running to supply the system?
2. Use the
Switchboard control
switch (on the switchboard) to change the controller to SWBD control.
3. Depending on the problem you can use the switchboard to do the following actions. If you cannot do these
actions during switchboard control, the controller will not be able to do them either. You will have to
continue troubleshooting to find the source of the problem.
a. Start the genset.
b. Use the GOV up and GOV down inputs to control the frequency from the genset.
c. Do a manual synchronisation and close the breaker.
d. Manually regulate the load to de-load the breaker, and then open the breaker.
e. Stop the genset.
