ComAp IG-NTGC HW 1.3-TO Replacement for InteliGen

Product Overview

ComAp IG-NTGC HW 1.3-TO Replacement for InteliGen: Smooth Transition, Zero Compromise on System Stability

When a generator control system goes down, every minute of unplanned downtime translates directly into production loss, safety risk, and costly emergency response. The ComAp IG-NTGC HW 1.3-TO — part of the proven InteliGen Series — is a purpose-built automatic gen-set controller designed for seamless integration into existing generator management architectures. Whether you are replacing a failed unit, upgrading from an earlier InteliGen hardware revision, or migrating away from a discontinued controller platform, the IG-NTGC HW 1.3-TO delivers the compatibility, reliability, and field-proven performance that industrial maintenance teams depend on.

At TOPNLMS, every IG-NTGC HW 1.3-TO unit is sourced directly from authorized supply channels, pre-shipment tested against ComAp factory specifications, and backed by a 12-month warranty. We stock this controller specifically to support facilities that cannot afford extended lead times when a critical gen-set goes offline.

Seamless Upgrade Solutions: Migrating to IG-NTGC HW 1.3-TO

A successful gen-set controller migration is never just about swapping the main control unit. The IG-NTGC HW 1.3-TO sits at the center of a broader control architecture, and understanding the surrounding components is essential for a smooth, low-risk cutover.

The most common starting point for maintenance engineers is the communication infrastructure. If your existing installation uses the ComAp IG-IB (InteliGen Internet Bridge) for remote monitoring or SCADA integration, the IG-NTGC HW 1.3-TO is fully compatible — no gateway reconfiguration is required. Similarly, facilities running Modbus RTU or CAN bus protocols to upstream SCADA or BMS systems will find that the IG-NTGC’s native protocol support eliminates the need for protocol converters during migration.

On the wiring side, the IG-NTGC HW 1.3-TO maintains the same terminal block layout as earlier InteliGen NT hardware revisions. This means existing engine sensor wiring — including oil pressure transducers, coolant temperature sensors, and fuel level senders — can typically be reconnected without modification. Engineers replacing units in the field frequently note that the ComAp IG-PTM (Power Transfer Module) and associated IG-AVRi (Automatic Voltage Regulator interface) remain fully compatible, preserving the integrity of the generator’s voltage regulation and load-sharing logic.

For facilities managing multiple gen-sets in parallel operation, the ComAp IG-MU (Master Unit) and IG-ECU (Engine Control Unit) modules continue to operate without firmware changes when paired with the IG-NTGC HW 1.3-TO. This is particularly valuable in data center, hospital, and industrial plant environments where parallel gen-set synchronization is critical to uninterrupted power supply.

Panel builders and system integrators should also verify the condition of terminal blocks and DIN rail mounting hardware within the control cabinet during the replacement process. Worn or corroded terminal connections are a common secondary failure point that, if left unaddressed, can cause intermittent faults on the newly installed controller. Replacing terminal blocks at the same time as the controller is a low-cost step that significantly reduces the risk of a repeat callout.

If the legacy installation includes an older InteliVision 5 or InteliVision 8 HMI panel, these remain compatible with the IG-NTGC HW 1.3-TO over the CAN bus interface. No HMI firmware update is required in most cases, though TOPNLMS recommends verifying the HMI firmware version against ComAp’s compatibility matrix prior to commissioning.

Finally, for sites where the gen-set feeds into a ComAp InteliMains NT (IM-NT) mains controller for automatic mains failure (AMF) operation, the IG-NTGC HW 1.3-TO integrates directly into the existing AMF logic without requiring changes to the IM-NT configuration. This preserves the site’s established load transfer sequences and alarm hierarchies.

TOPNLMS maintains ready stock of the IG-NTGC HW 1.3-TO to support urgent replacement scenarios. Units are dispatched within 1–3 business days from Xiamen, with worldwide express shipping options available. Each unit undergoes pre-shipment functional testing and is packaged in anti-static, impact-resistant materials to ensure safe arrival.

Retrofit Guidance FAQ

Q1: Can the IG-NTGC HW 1.3-TO replace an earlier InteliGen NT hardware revision without rewiring?
In the vast majority of installations, yes. The IG-NTGC HW 1.3-TO maintains backward-compatible terminal block assignments with earlier InteliGen NT revisions. Existing engine sensor wiring, relay output connections, and communication cables can typically be reconnected directly. TOPNLMS recommends reviewing the ComAp wiring diagram for your specific engine interface before commissioning to confirm pin-for-pin compatibility.

Q2: Is the existing InteliGen configuration file (*.igc) compatible with the IG-NTGC HW 1.3-TO?
Configuration files created with ComAp’s InteliConfig PC software are generally portable between InteliGen NT hardware revisions. The IG-NTGC HW 1.3-TO supports configuration upload via the standard USB/RS-232 programming cable. If the legacy configuration was created on a significantly older firmware version, a firmware upgrade on the new unit may be required before loading the file — TOPNLMS technical support can advise on this process.

Q3: What communication protocols does the IG-NTGC HW 1.3-TO support for SCADA integration?
The IG-NTGC HW 1.3-TO natively supports Modbus RTU over RS-232 and CAN bus. With the optional IG-IB Internet Bridge module, Modbus TCP/IP and web-based remote monitoring are also available. This makes the controller compatible with the majority of industrial SCADA, BMS, and energy management systems currently in use, without requiring additional protocol gateways.

Q4: What does the 12-month warranty cover, and what is the replacement process?
TOPNLMS’s 12-month warranty covers manufacturing defects and functional failures under normal operating conditions. Each unit is tested prior to shipment. In the event of a warranty claim, TOPNLMS provides a replacement unit or full refund within the warranty period. Contact our technical team at [email protected] with your order number and a description of the fault — our average response time is within 24 business hours.

Warranty Assurance
