ComAp InteliDrive DCU Industrial Engine Controller

An engine controller for pump, compressor and industrial drive sets

The ComAp InteliDrive DCU Industrial is a specialised engine controller for land-based industrial machinery. It controls, monitors and protects diesel or gas engines and the driven application, for engine-driven compressors and pumps running either at a single speed (SS) or at variable speed (AS). The datasheet lists the application as pump and compressor sets.

It speaks to up to ten CAN J1939 devices (or KWP2000 type) at the same time, which suits machinery with several ECUs and aftertreatment modules. Speed control is available for Tier 4 Final and Stage V engines, and the front panel is sealed to IP65. A low-temperature version is also offered under a separate order code.

Technical specifications

Extension modules and displays

More than 100 binary inputs and outputs are available through CAN modules.

Functions

The controller offers integrated load and clutch control, load sharing for propulsion engines, virtual shared inputs and outputs over CAN, a running hours meter, a starts counter and configurable Modbus registers. A large PLC interpreter and monitor are included, and remote monitoring is possible over Modbus, TCP/IP, AirGate and WebSupervisor.

Specifying notes

Confirm the engine ECU protocol and its J1939 messages, the speed signal and the sensor types against the analogue inputs. Hardware figures in the datasheet include 4.7 k ohm binary input impedance with a minimum input duration of 110 ms, a D+ output up to 300 mA, 10-year flash data retention, and 9 W heat radiation. The datasheet issue date is 2021, so check current firmware and hardware version with the project data. For generator-set duty look instead at gen-set controllers such as the ComAp InteliGen4 200 paralleling controller.

How the ComAp InteliDrive DCU ID2DCUINBAA works

The controller starts, runs and stops an engine that drives a pump or a compressor. It reads engine speed, oil pressure, temperature and other signals, and talks to the engine control unit over CAN J1939. It keeps the speed at the setpoint, and it can also control load and clutch outputs. If a value goes outside its limits, the controller raises an alarm or shuts the engine down.

Installation, commissioning and maintenance notes for the ID2DCUINBAA

Mount the controller in the panel and fuse the supply. Wire the engine inputs, the outputs and the speed pick-up. Connect the CAN link to the ECU. Load the configuration and test the start, stop and alarm functions before the set goes into service. Read the history after tests.

Documents and quotation

Seven Star LLC supplies ComAp engine and generator controllers on request. The datasheet is attached. Send the engine make and ECU type, the application, the sensors and the communication requirement. Related parts are in Diesel Generator Spare Parts. Confirm the version before ordering, and state whether the low-temperature variant is needed for a cold-start site, since it carries a different order code.

Analogue inputs AI1 to AI4 are unipolar with 10-bit resolution and jumper-selectable voltage, resistance or current ranges, while AI5 to AI8 are bipolar with up to 16 bits and thermocouple capability. Vibration is rated 5-25 Hz at 1.6 mm and 25-100 Hz at 4 g, with shock of 200 m/s2.
