Cummins 300-6314-01 PowerCommand Display-Control Assembly

Overview

The Cummins 300-6314-01 is a genuine PowerCommand display-control assembly used on Cummins/Onan industrial and standby diesel generator sets, providing the operator interface for engine and generator monitoring, alarm annunciation, and control functions. Despite the generic “Engine” label sometimes attached to this part number, the 300-6314-01 is not an engine component itself – it is the symbol-and-text control display panel (Display-Cntrl, SYM, ENG T) that reads engine and generator status from the genset control module and presents it to the operator at the control panel, and it has been discontinued by Cummins as an OEM part, now supplied through the aftermarket parts network.

Seven Star LLC supplies the Cummins 300-6314-01 PowerCommand display-control assembly as an authorized-partner channel to standby power operators across Oman and the GCC, supporting hospitals, data centres, oil and gas facilities, and commercial buildings that run Cummins/Onan diesel generator sets equipped with this control panel. Because the 300-6314-01 has been discontinued and superseded across several PowerCommand HMI generations, our team can help confirm whether the direct replacement or a compatible successor display is the correct fit for your specific genset control panel before ordering.

Measurement and Operating Principle

The 300-6314-01 display does not measure engine parameters directly; it receives digitized engine and generator data – oil pressure, coolant temperature, battery voltage, RPM, fault codes, and generator output parameters – from the genset’s engine control module (ECM) and generator control module over the internal control bus, then renders that information on its symbol-and-text LCD for the operator standing at the control panel. The display also provides the local interface for alarm acknowledgment, control mode selection (auto/manual/off), and menu navigation into diagnostic and configuration screens.

Because the display is the operator’s primary window into genset health, its accuracy and responsiveness directly affect how quickly a facility engineer can identify a developing fault – low oil pressure, high coolant temperature, or a charging system fault – before it escalates into an unplanned shutdown. A failed or unreliable 300-6314-01 display can leave a generator effectively unmonitored at the panel level even while the engine control module continues to function normally in the background.

Engineering Design

The Cummins 300-6314-01 display-control assembly is built to the PowerCommand control panel form factor used across a range of Cummins/Onan industrial genset control panels, with a keyed connector and mounting footprint designed for direct swap into the existing panel enclosure. The unit weighs approximately 0.72 kg (1.59 lbs) and is classified within Cummins’ electrical products range under the power generator control subcategory, reflecting its role as a control and monitoring component rather than a mechanical engine part.

As a discontinued OEM part, the 300-6314-01 is now sourced through the Cummins/Onan aftermarket parts network, where genuine remanufactured and new-old-stock units are available as direct-fit replacements. Facilities running older PowerCommand-equipped gensets rely on this continued parts availability to keep legacy control panels in service without a full panel retrofit.

Industrial Applications for the Cummins 300-6314-01

The Cummins 300-6314-01 display-control assembly is used on standby and prime power diesel generator sets serving hospitals, data centres, oil and gas facilities, telecommunications sites, and commercial buildings across Oman where uninterrupted power is critical. It is typically replaced when the existing panel display fails, becomes unreadable, or loses communication with the genset control module, restoring full local monitoring and control capability without needing to replace the entire control panel.

Seven Star LLC, as an authorized partner supporting Cummins/Onan standby power equipment in Oman and the GCC, helps facility engineers in Muscat, Sohar, Duqm, and Salalah source the correct display-control assembly for their genset control panel generation, minimizing downtime during scheduled maintenance or emergency panel repairs.
