IGS-NT Combi, SW Version 3.0, ©ComAp – May 2013
IGS-NT-Combi-3.0 Reference Guide.PDF
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.
