Proven Application Environments
The IG-NTC HW v1.3-TO has been deployed across a wide spectrum of critical power infrastructure:
- Data Centers & Colocation Facilities: AMF and load-sharing control for N+1 and 2N generator configurations, ensuring sub-10-second transfer times and zero unplanned downtime.
- Industrial Manufacturing Plants: Continuous prime power management for process lines where utility interruption causes significant production loss.
- Hospitals & Healthcare Facilities: Life-safety standby power systems compliant with IEC 60364 and NFPA 110 requirements.
- Marine & Offshore Platforms: Genset paralleling on vessels and offshore rigs where vibration resistance and compact form factor are critical.
- Telecom Base Stations: Remote AMF control with SCADA integration via RS-485 Modbus for unmanned sites.
- Mining & Heavy Industry: Robust operation in high-dust, high-vibration environments with extended temperature range.
- Commercial Real Estate: Multi-genset synchronization for large building complexes with utility paralleling capability.
Engineering Advantages
- Multi-Unit Paralleling: Native CAN bus architecture supports synchronization of up to 32 gen-sets without external synchronizing relays, reducing panel complexity and wiring cost.
- Flexible AMF Logic: Configurable mains failure detection thresholds (voltage, frequency, phase sequence) with programmable transfer delays to match utility requirements.
- Engine Protection Suite: Integrated monitoring of oil pressure, coolant temperature, fuel level, battery voltage, and speed with configurable alarm/shutdown thresholds.
- SCADA-Ready Communication: RS-485 Modbus RTU and optional Ethernet Modbus TCP allow seamless integration with plant DCS, BMS, or SCADA platforms.
- ComAp PC Suite Compatibility: Full parameter configuration, event log download, and firmware updates via InteliConfig software — no proprietary hardware dongle required.
- Field-Proven HW v1.3-TO Revision: Incorporates hardware improvements addressing early-revision I/O noise susceptibility, making it the preferred replacement for HW v1.0–v1.2 installations.
- Battery-Backed Operation: Wide-range DC supply (8–36 V) ensures controller remains operational during deep battery discharge scenarios common in remote standby sites.
System Architecture & Signal Flow
The IG-NTC operates as the central intelligence node in a gen-set control panel. The typical signal flow is as follows:
- Mains Monitoring: Three-phase voltage and frequency are continuously sampled. On detection of mains failure (per configured thresholds), the AMF sequence initiates.
- Engine Start Sequence: The controller issues a start command to the engine ECU or starter relay, monitors crank/run feedback, and enforces configurable start attempts and warm-up timers.
- Voltage & Frequency Stabilization: Generator output is monitored; the controller waits for stable V/Hz within tolerance before issuing a breaker close command.
- Load Transfer: The generator breaker closes (and mains breaker opens in open-transition, or synchronization occurs in closed-transition mode).
- Parallel Operation (Multi-Unit): Via CAN bus, multiple IG-NTC units share load data and execute droop or isochronous load sharing algorithms.
- Mains Return & Retransfer: On mains restoration, the controller executes a configurable retransfer sequence with cool-down timer before shutting down the engine.
- Event Logging & Alarm Annunciation: All events, alarms, and shutdowns are time-stamped and stored in non-volatile memory, accessible via front panel or PC Suite.

Technical FAQ
Q: Is the IG-NTC HW v1.3-TO compatible with ComAp InteliConfig software?
A: Yes. InteliConfig (all versions supporting InteliGen firmware 2.x and above) is fully compatible. Parameter upload/download and event log retrieval are supported via RS-232 or USB-RS232 adapter.
Q: Can this controller handle closed-transition (make-before-break) transfer to mains?
A: Yes, with appropriate configuration and a synchronizing module. The IG-NTC supports both open-transition and closed-transition (soft transfer) modes when the synchronization check relay output is wired correctly.
Q: What is the maximum number of gen-sets that can be paralleled on a single CAN bus network?
A: The InteliGen CAN bus architecture supports up to 32 controllers per network segment, suitable for large data center or industrial plant configurations.
Q: Is Modbus TCP supported natively or does it require an expansion module?
A: The base IG-NTC unit supports Modbus RTU over RS-485 natively. Modbus TCP over Ethernet requires the optional IB-NT (Internet Bridge) communication module.
Q: What is the difference between HW v1.3-TO and earlier hardware revisions?
A: HW v1.3-TO incorporates revised analog input filtering circuitry and improved EMC shielding on the I/O connector block, addressing noise-induced false alarms reported in v1.0–v1.2 field installations. It is the recommended replacement revision for all legacy IG-NTC deployments.
Q: Can Konmask supply the matching InteliGen expansion modules (IL-NT, IM-NT)?
A: Yes. Contact us with your full BOM and we will source the complete module set from the same verified supply chain.
