2.2 Applications with GCB control and no MCB Typical applications:

• MRS (SPM): Manual or remote start/stop of a single engine Typical applications:

• Multiple sets running in island-parallel Typical applications:

• CHP with no island operation (no backup)

2.3 Applications with GCB control with external MCB control Typical applications:

• AMF with multiple sets running in island-parallel. MCB controlled by a simple mains protection relay or InteliMains

• AMF with no break return (multiple sets). MCB controlled by InteliMains-NT. • Parallel to Mains with AMF for multiple sets (CHP) MCB controlled by InteliMains-NT.

Typical applications:

• CHP with external MCB control. Normally the load is higher than gen-set capacity and non-preferential load must be switched off before gen-set can be switched to island operation.

2.4 Generic applications Controller performs individual steps like:

• Gen-set start • GCB dead bus closing • Synchronizing • Load control mode • Reverse synchronizing • Gen-set stop

Steps are driven by commands from an external device, e.g. PLC. This device is responsible for all sequencing (steps order). Typical applications:

• Complex systems with several buses where PLC controls each step of the gen-set. • Complex CHP applications controlled from a central PLC

Required setting: Set SysAMFstrtDel and SysAMFstopDel setpoints at 1s for fast response on BI Sys start/stop Input MCB FEEDBACK should not be configured

Description without MGCB • When BI Sys start/stop closes, sets are starting with a delay SysAMFstrtDel. The first set with a

correct voltage and frequency closes the GCB to the dead bus, others are synchronized. • When the relay BI Sys start/stop is opened, all GCBs are opened at the same time with a delay

SysAMFstopDel.

Description with MGCB • When BI Sys start/stop closes, sets are starting with a delay SysAMFstrtDel. The first set with a

correct voltage and frequency closes the GCB to the dead bus, others are synchronized. • BI Load res 2 is controlled by MGCB to differentiate the load reserve necessary before closing of

MGCB (setpoints LoadRes Strt 2 and LoadRes Stp 2), and operational load reserve while the system is loaded (setpoints LoadRes Strt 1 and LoadRes Stp 1).Typically before MGCB closing the higher reserve is needed to absorb the full load. Once loaded, the load reserve can be reduced to e.g. level of the biggest single consumer.

• MGCB is closed by BO Syst res 1 OK of any running genset and then held by MGCB feedback. • When the relay BI Sys start/stop is opened, all GCBs are opened at the same time with a delay

SysAMFstopDel. Loss of voltage at the bus opens MGCB.

• BI Load res 2 is controlled by MGCB to differentiate the load reserve necessary before closing of MGCB (setpoints LoadRes Strt 2 and LoadRes Stp 2), and operational load reserve while the system is loaded (setpoints LoadRes Strt 1 and LoadRes Stp 1).Typically before MGCB closing thhigher reserve is needed to absorb the full load. Once loaded, the load reserve can be reduced to e.g. level of the biggest single consumer.

Required application System configuration/ default archive: IG/IS-MINT.ant and IM-MCB/MGCB.ant

Description without MGCB • The IM-NT controller opens MCB after the mains fails or after the gen-sets are running according to

setpoint AMF settings:MCB opens on. • The IM-NT controller closes binary output Sys start/stop which is connected to Sys start/stop inputs

of the gen-set controllers if: a) If IM-NT binary input Rem start/stop gets active (AUT mode only). b) If AMF condition is sensed in IM-NT and the gen-set group should be started as stand-by power

source (AUT mode only). c) If PeakShaving function senses that it is suitable to start the gen-set group in order to lower the

mains import (AUT mode only). d) If Start button is pressed on IM-NT front panel or remotely (MAN mode only). The signal can be

deactivated by pressing the Stop button. If the controller is switched from AUT to MAN mode, the internal status of the flip-flop circuit created by Start-Stop buttons is set to follow the previous state in AUT mode. E.g. if the gen-set group has run in an AMF situation in AUT mode, switching to MAN will not stop it (= Sys start/stop output stays active).

• After binary input Sys start/stop closes the gen-sets are starting with a delay SysAMFstrtDel. It is similar to setpoint EmergStart del in SPtM application. The first set with a correct voltage and frequency closes the GCB to the dead bus, others are synchronized.

• When the mains returns, IM-NT synchronizes gen-sets to the mains with limitations given by setpoints ProcessControl:ParallelEnable and Synchro enable (see Table on p.7 in IM-NT-MCB-MGCB-X.X.pdf).

Description with MGCB • The IM-NT controller opens MCB after the mains fails or after the gen-sets are running according to

setpoint AMF settings:MCB opens on. • The IM-NT controller closes binary output Sys start/stop which is connected to Sys start/stop inputs

of the gen-set controllers if: a) If IM-NT binary input Rem start/stop gets active (AUT mode only). Before the output Sys

start/stop is activated, the MGCB close command is issued (if ProcessControl:MGCBparalClose = YES).

b) If AMF condition is sensed in IM-NT and the gen-set group should be started as stand-by power source (AUT mode only). MGCB is not closed before the GCBs but only after a reasonable amount of gen-sets have synchronized to the bus (load reserve achived). c) If PeakShaving function senses that it is suitable to start the gen-set group in order to lower the


mains import (AUT mode only). Before the output Sys start/stop is activated, the MGCB close command is issued (if ProcessControl:MGCBparalClose = YES). d) If Start button is pressed on IM-NT front panel or remotely (MAN mode only). The signal can be deactivated by pressing the Stop button. If the controller is switched from AUT to MAN mode, the internal status of the flip-flop circuit created by Start-Stop buttons is set to follow the previous state in AUT mode. E.g. if the gen-set group has run in an AMF situation in AUT mode, switching to MAN will not stop it (= Sys start/stop output stays active).


• When the mains returns, IM-NT synchronizes gen-sets to the mains with limitations given by setpoints ProcessControl:ParallelEnable and Synchro enable (see Table on p.7 in IM-NT-MCB-MGCB-X.X.pdf).

Hint: It is possible to use virtual shared inputs/outputs to connect for example Sys start/stop output from IM-NT to corresponding binary input of all controllers instead of hardwiring it. See chapter Shared virtual I/O periphery. PeakShaving function should be used in order to lower the mains import (AUT mode only).

PeakShaving settings: PeakLevelStart: PeakLevelStop to 32000 kW PeakLevelStop: 0 to PeakLevelStart kW PeakAutS/S del: 1-3200 s. Function is active only for PeakAutS/S del <> OFF. If PeakLevelStart is reached for PeakAutS/S del time then the IM-NT controller closes binary output Sys start/stop which is connected to Sys start/stop inputs of the gen-set. Sys start/stop is deactivated after PeakLevelStop is reached for PeakAutS/S del. Hint: The Peak start/stop function activates the common output signal Sys start/stop in IM-NT. The signal is intended to be directly connected to Sys start/stop inputs of all gen-set controllers in the system, e.g. using SHBIN/SHBOUT peripherals.

Required application System configuration/ default archive: IG/IS-MINT.ant and IM-MCB/BTB.ant

Description without MGCB • The IM-NT (MCB) controller opens MCB after the mains fails or after the gen-sets are running

according to setpoint AMF settings:MCB opens on. • The IM-NT controller closes binary output Sys start/stop which is connected to Sys start/stop inputs

of the gen-set controllers in the corresponding group if: - If IM-NT (MCB) binary input Rem start/stop gets active (AUT mode only). - If AMF condition is sensed in IM-NT (MCB) and the gen-set group should be started as stand-by power source (AUT mode only). - If PeakShaving function senses that it is suitable to start the gen-set group in order to lower the mains import (AUT mode only). - If Start button is pressed on IM-NT (BTB) front panel or remotely (MAN mode only).

If the controller is switched from AUT to MAN mode, the internal status of the flip-flop circuit created by Start-Stop buttons is set to follow the previous state in AUT mode. E.g. if the gen-set group has run in an AMF situation in AUT mode, switching to MAN will not stop it (= Sys start/stop output stays active).


• When the mains returns, IM-NT (MCB) synchronizes gen-sets to the mains with limitations given by setpoints ProcessControl:ParallelEnable and Synchro enable (see Table on p.7 in IM-NT-MCB-MGCB-X.X.pdf).

• The gen-set controllers know whether they are connected to the Mains from binary input MCB feedback that can be configured on binary output InMainsParal (using VPIO for instance). This binary output is distributed over the CAN bus and indicates which BTBs are closed and so which logical groups are interconnected and connected to the Mains. Based on this information the gen-set controllers are controlled by one or another IM-NT (MCB) controller.

Description with MGCB • The system with this topology has to be separated into 4 logical groups by 3 IM-NT (BTB)

controllers. It is not possible to use IM-NT MGCB application for this purpose. • The IM-NT (MCB) controller opens MCB after the mains fails or after the gen-sets are running

according to setpoint AMF settings:MCB opens on. • IM-NT (BTB) controller closes automatically BTB/MGCB if

- bus voltages are within the limits (Sync ctrl:Phase window, Voltage window) - there is voltage on one of the buses and closing to dead bus is enabled by ProcessControl:DeadBusClosing - binary input BTB disable is not closed - it is enabled by setting of ProcessControl:Synchro enable, Mains coupling setpoints





Hint: It is possible to use virtual shared inputs/outputs to connect for example Sys start/stop output from IM-NT to corresponding binary input of all controllers instead of hardwiring it. See chapter Shared virtual I/O periphery. For BTB controllers the BI BTB Feedback should be configured as Group link input as well.

4. Virtual peripherals

4.1 Integrated PLC The NT family controllers contain a virtual PLC module that can be “connected” to the system. The activation of the PLC is done in the Modules card in GenConfig. Depending on the controller HW type, a different number of functions and function types is available. See the table below for complete overview. The internal PLC can simplify or even avoid the external logic in a switchboard, bringing another level of control system integration. The PLC has analog and binary inputs and outputs that can be interfaced to any suitable controller analog value, physical or logical binary input and output.

PID analog input can be configured to any analog value (physical input) Requested value, Input Bias and PID setting can be configured as constant or setpoint or analog value (physical input) from the object list. PID works when binary input GATE is not configured. Sensor fail on measured (or requested) value set PID output to Input bias and blocks PID calculation. There is configurable LoLimit (for 0V or 0mA output) and HiLimit (10VDC or 20mA) for analog output configuration.

Output Up Binary output UP. Output Down Binary output DOWN. Period Period of PID calculation: 100 to 5000 msec. Actuator Period of PLC calculation: 100 to 5000 msec.

PID analog input can be configured to any analog value (physical input) Requested value and PID setting can be configured as constant or setpoint or analog value (physical input) from the object list. Active binary input GATE blocks PID calculation - binary outputs are inactive. Example: Adjust 5 sec when time from open to close valve is 5 sec. Sensor fail on measured (or requested) value blocks PID calculation. Hint: Constants should be set 10 times higher then in IS-CU for the same behavior

I/O Note Input cnt Counter binary input. Input clr Counter clear (reset) binary input. Input lim Analog – limit level input (max 65535). Output Binary output – over limit indication.

Counter can counts rising or falling edge. The result is stored in volatile memory and it is lost when controller is switched off. Binary output is activated when counter is over limit. Output stays closed even if counter overflow over maximum 65535. Counter contains binary Reset input (level sensitive) that set counter to zero, resets binary output and blocks counting when active. Maximal counter value is 65535 (16 bites wide) and continues to zero. The minimal pulse period is 0,2 sec (max 5 Hz) - in this case the counter overflow after 218 minutes.

Timer Periodic signal generator. Maximal number of functions: 2

I/O Note Input reload val Analog value specifies period of Binary output change [ 0,1s]. Input reload Closed binary input Reload reloads timer period when closed. Input run Binary input must be closed to activate Timer. Output Binary output.

Binary output changes state with period given by analog Input reload val [ 0,1s ] when Binary input Run is closed and Binary input Reload is opened. Timer starts with low state period when selection Firs down is ticked. E.g. Output changes state each 10 sec when input value is 100. Timer reloads (accepts period change) in the end of period or when binary input Reload is closed. Reload function can be useful when very long time period is running.

Delay Delay module – adjustable delay for rising/falling or the both edges of an output pulse. Maximal number of functions: 16

This module allows to create own output pulse, which is derived from an input pulse by a delay of its rising/falling or the both edges. With using of delay block, a condition Tup < Tdown + TIN has to be fulfilled. Note: output pulse is not generated if condition Tup < Tdown + TIN is not fulfilled. The function can be used as a noise filter – it does not accept an input pulse shorter than 100 ms.

Analog output follows analog input if Reset is active if it is not active analog output is frozen and stays at the last known value. Example: The regulation PID module with binary output is used to maintain required heating temperature through the UpDn module by change of valve position. Before the engine is ready to take, the load the logical binary output LBO: Ready to Load is inactive and the valve position is given by the Default output setpoint. When the engine is ready to take the load the LBO: Ready to Load is active and PID module changes the heating temperature by series of pulses and accordingly the UpDn module reaches the required temperature (Req.temp. setpoint) by the change of valve position. The characteristic of the PID regulation loop is given by the PLC setpoints: GAIN, INT and DER. The changing speed (per second) of the valve position is limited by the Speed up and Speed down setpoints. The AO: Valve position can be changed in the limits given by the Limit1 and Limit2 setpoints.

4.2 Internal virtual I/O periphery The controller features many logical outputs, i.e. outputs that could be configured to physical outputs (terminals of the controller itself or of expansion modules). But sometimes it is necessary to bring the output signal back to the input, if a special behaviour is required. E.g. logical binary output Batt volt is linked with only a Warning type alarm, and from some reason it is required that the engine be stopped in this case (at certain site). You can achieve this by bringing the signal to physical output and then connect it to a physical input. Then this input can be configured with a Shutdown type protection. The disadvantage of the above solution is that you are losing one input and one output of the controller / expansion module, which is costly. The virtual periphery simulates this within the controller, bringing a group of “physical outputs”, linked with a group of “physical inputs”. So you can configure a logical output of the controller to this module, and then configure a protection (or a link to logical input) to the “physical input“ part of the module, as you would do with real inputs. The same can be done with PLC I/O, so e.g. a complex evaluation of a protection in PLC can be brought directly to an input configured for this protection type.

4.3 Shared virtual I/O periphery It is often required that certain signals be brought to all controllers in the group. For example MCB feedback, System Start/Stop, Common Shutdown signal etc. These are all binary signals. Sometimes analog signals are required as well, like engine room temperature signal, where too high temperature can cause the nominal power of all gen-sets in the room to be reduced (power derating function). IG/IS-NT controllers have a provision to make it easier when designing such an application. These controllers have a sophisticated system of shared virtual modules, where one controller is a signal server and the other controllers are recipients of this signal. The signals are distributed via the CAN bus which typically interconnects all the controllers on one site.

Configuration These virtual modules can be added / removed like any other HW module in GenConfig / card Modules. Then they appear in the list of inputs or outputs in the card I/O.

SHBOUT/SHAOUT modules They behave like standard output modules, but the signals assigned to them don’t appear on any physical output, instead of that are distributed via the CAN bus to other controllers. Each module has 8 outputs.


ShBIN/SHAIN modules They behave like standard input modules, i.e. you can assign any logical input signal that is available in the controller to them, or configure a protection based on their activity. Each module has 8 inputs.

SHBOUT + SHBIN modules There are four channels (i.e. 4 groups of 8 binary inputs/outputs) available for binary signal sharing. Each channel can have its source (SHBOUT module) in different controller. All other controllers can be configured as the recipients of this channel (SHBIN module).

In this particular example, the SYSTEM START signal which should command the start / stop for all the controllers on the site, is transferred from the terminal (physical binary input) to the SHBOUT module. All other controllers on the site should be configured in the way that the signal is picked up in the same position (1-8) where it has been assigned to in SHBOUT module. The signal is then picked up from the module and can be used by the controller’s FW or PLC like any other physical binary input:

5. Controller configuration tricks

Force value Force value feature enables a Binary input to switch between two different values of a setpoint:

BI: Force value Nominal power Opened 100 kW Closed 200 kW

Or between (FV) setpoint and Analog input (or in general any value):

BI: Force value Nominal power Opened 100 kW Closed Analog input (given

by the curve converted output)

Hint: If Force value is active, it is not possible to change setpoint value (e.g. from InteliMonitor). Force value has to be deactivated first. Configure Force value in GenConfig.
