for Jenbacher XT and XT3

DIA.NE XT/XT3 remote alarm acknowledgement

The GE Jenbacher XT and XT3 engine controllers are a very comprehensive and robust engine management system. The controller’s warning and alarm conditions are displayed and managed on the local HMI or, if available, through the WIN web application from remote.

Alarm conditions will almost always result in the generator being switched off and locked out for further operation until the alarms are physically cleared and acknowledged by an operator. By default, remote acknowledgement of alarms is not allowed for in a controller. Therefore, returning the generator to operation requires an operator to be locally present at the control panel.

Adding the Stark RESET module to your XT/XT3 engine controller empowers you to get your engines restarted faster when you are away from the panel.

Remote alarm management

Increased generator runtime

Reduced staff travel time


RESET: Single 24VDC interface for integration with client PLC

RESET PLUS: WIN integration for full visibility

Requirements XT or XT3 controller

For RESET: client SCADA for integration

For RESET PLUS: WINserver connected to each controller

Remote network access to either client SCADA or WINserver

Reset Plus

A Stark RESET module should be installed by an competent technician in each XT/XT3 control panel. A single 24VDC input is then provided from the client’s PLC to provide a RESET command.

The RESET functionality is integrated with the client’s SCADA system from where the operator diagnoses, manages and acknowledges the XT/XT3 warnings and alarms. Remote access to the SCADA system allows for remote acknowledgment of the XT/XT3 alarms.

Depending on your existing SCADA configuration, managing individual warning and alarm conditions for the controller may not be feasible. Although possible, often the SCADA only offers a high-level interface for the XT/XT3 controller.

In this case, diagnostics for safe acknowledgement may be available through the GE Jenbacher WIN web application. Most generators are installed with the necessary WINserver hardware which offers operators a HMI-like remote interface.As an optional add-on to the Stark RESET module, RESET PLUS provides an upgrade to the existing WIN web application. As such, the operator can diagnose, manage and acknowledge

alarm conditions through a familiar and comprehensive interface. Remote access to the WIN web application allows for remote acknowledgment of the XT/XT3 alarms.  Although still possible, a 24VDC command signal from the client PLC is no longer required.

With RESET PLUS, the WIN web application is upgraded to allow for alarm acknowledgement.

The WIN alarm management page is upgraded with an additional RESET button.

User Management and Critical Alarms

Alarm conditions that have not been physically cleared, can obviously not be acknowledged. For example, a low water pressure condition will need the water pressure to be restored before the alarm can be acknowledged. Nontheless, even acknowledgement of cleared alarm conditions inherently carries some level of risk.

Stark highly recommends that only experienced operators use the Stark RESET functionality, and only following in-depth diagnostics of the alarm condition. Nonetheless, not all alarm conditions carry the same risk and the client may wish to have certain alarms blocked from remote acknowledgement.

The Stark RESET module does not offer a possibility to implement selective acknowledgement. This must be implemented through the operator interface in SCADA, or it can be provided through RESET PLUS in the upgrade of the WIN web application.


Choosing between Stark RESET or RESET PLUS depends on the desired operator interface to manage alarms. Stark recommends:

  • RESET, when the funcitonality will be integrated in an existing SCADA system which has good visibility of alarm conditions in the XT controller.

  • RESET PLUS, when a WINserver is available with remote access and the client whishes to use this as the in-depth alarm management interface.
