13. Troubleshooting
13.1 Troubleshooting the system in Switchboard control
The exact procedure for operating the system in Switchboard control depends on your switchboard design. Follow the guidelines
from the switchboard supplier.
Class societies require a certain amount of protections included in the switchboard. For example, there must be a synchronisation
check before closing a breaker.
Operate system in Switchboard control
You should only operate the system in Switchboard control, if you are a trained and experienced operator. Even though
the controller protections are active, you can create undesirable conditions during switchboard control. Your actions can
also disrupt the power supply.
General information about switchboard control
When you place a controller in Switchboard control, it no longer controls the GOV and AVR regulators. All logic for the genset (start
and stop) and breaker (open and close) is deactivated. The controller's protections remain active.
Controller protections during switchboard control
During switchboard control, the controller protections respond to alarm situations. However, the controller does not
prevent you from creating alarm situations.
How to troubleshoot in Switchboard control
1. Make sure there is enough power available for the system. You might need to have extra gensets running.
2. Move the Switchboard control switch (on the switchboard) to change the controller to Switchboard control.
3. Depending on the problem, you can use the switchboard to do a series of actions:
a. Start the genset.
b. Use the GOV up and GOV down inputs on the switchboard 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.
4. If you cannot do these actions with the switchboard, the controller can not do them either. You must continue your
troubleshooting to find the source of the problem.
13.2 Troubleshooting alarms
The system has many pre-configured and configurable alarm protections. An active alarm has an active alarm protection to protect
the system and equipment. Activated alarms require action to resolve the problem in the system.
