Load shedding outputs for partial load switching.  
Derating 1 act    
Indicates activity of derating function 1. 
Derating 2 act    
Indicates activity of derating function 2. 
 
Binary outputs – Control loops 
Speed up  
Speed dn  
Binary outputs for Synchronizing and Load control. Outputs can be used instead of analog Speed governor 
output for older engine types. Minimum pulse duration is 0,15 sec. Maximum pulse duration is 10,0 sec. 
Hint:
 
When Speed governor output stays near to the limit value (SpeedGovLowLim+0,2 V or SpeedGovHiLim-0,2 
V) for more than 2 sec, the “Wrn SpdRegLim” message is displayed in the Alarm list and recorded to History. 
When AVRi output stays on <2% or >98% for more than 2 sec, the “Wrn VoltRegLim” is displayed in the 
Alarm list and recorded to History. 
Corresponding warning is blocked when Binary outputs Speed Up, Speed Dn or AVR up, AVR dn are 
configured to a physical BO or VPIO. 
It is not recommended to process these signals via the internal PLC, as the precise signal timing would be 
distorted.

These outputs are controlled remotely from InteliMonitor or other tool. The user selects the requested state 
of these outputs via the buttons in this program. 
Hint: 
Outputs can be used to switch on/off some auxiliary devices in the control panel.
