Parameter Range Default Notes
For relay outputs, depending on the relay output settings, the effect
might not be linear.
Manual AVR
slope
0 to 200 %/s
10 %/s of genset
nominal reactive
power
The controller increases or decreases the analogue output by this
amount when the digital input is activated.
For relay outputs, depending on the relay output settings, the effect
might not be linear.
Parameters
Controller types: These parameters only apply to the GENSET and EMERGENCY genset controllers.
These parameters define the controller mode after certain other modes and events. You can configure these parameters under
Configure > Parameters > Local power management > Return modes > After SWBD control.
If the controller was put under Switchboard control, but is now no longer under Switchboard control, this parameter determines the
controller mode.
Table 2.7
Mode parameter
Options Notes
No mode change
The default. After Switchboard control, the controller returns to the mode it was in before it was under
Switchboard control.
SEMI mode After Switchboard control, the controller mode is semi-automatic (SEMI).
AUTO mode After Switchboard control, the controller mode is automatic (AUTO).
Events that force controllers under switchboard control
The following events force all the controllers in the section to operate under Switchboard control:
• The Power management > Force all controllers in section to SWBD control command or digital input on ANY controller in the
section.
• Any breaker position failure in the section.
• Any critical alarms in a connected controller (that is, a controller with a closed breaker) in the section:
◦ Duplicate controller ID
◦ Missing all controllers
◦ System not OK alarm on any controller (that is, there is a problem with a hardware module in that controller)
◦ ACM voltage measurement error alarms
◦ [Source] L1-L2-L3 wire break
◦ [Busbar] L1-L2-L3 wire break
◦ [Source] L1 wire break
◦ [Source] L2 wire break
◦ [Source] L3 wire break
◦ [Busbar] L1 wire break
◦ [Busbar] L2 wire break
◦ [Busbar] L3 wire break
• Power management system disabled, as shown by any of these alarms:
◦ PMS disabled due to an error
◦ Network protocol incompatible
◦ Different single-line configurations
◦ Controller type mismatch
◦ Single-line missing/none active
◦ Priority network error
