NOTE:  
RPM of the gen-set has to be measured using pick up or via ECU. It is not possible to evaluate the RPM 
form frequency of the generator voltage when cleaning mode is in use. 
 
WARNING!  
Be aware that activation of LBI CLEANING ensures only that under voltage and under frequency protection is 
not active and allows gen-set to run with frequency and voltage out of limits of protections. Activating of this 
input does not ensure that the voltage excitation is really switched off. The excitation of the generator has to 
be unconditionally switched off directly on the AVR of generator while the cleaning function is in use! 
Automaticallocation of addresses on intercontroller CAN2 
In Combi application it is possible to use the function of automatic negotiation of addresses of controller on 
CAN2. For more information about this function se the description of setpoint CANnegotiation. 
Force value – step by step guide 
In this chapter there is complete step by step guide which shows how to use Force value function of the 
controller. 
Forcing of values is used to change particular setpoint temporarily by activation of related Binary Input. This 
is used to change function of controller under given conditions (e.g. there are two different periods during the 
day when Export limit given by distribution network is required or not). 
WARNING!  
Setpoints must not be written continuously (e.g. via Modbus connection)! If continuous change of setpoints 
is required, combination of External values and Force value function needs to be used. The memory that 
holds setpoints is designed for up to 10
5
 writings. Than memory may be damaged! 
Setpoints that are available for forcing may be identified by Force value button on the right side in GenConfig 
(see the figure below). 
 
When the button is clicked, Force value dialog appears.
