Configure Generator Test EPSS

Generator Test EPSS includes:

• Generator Test EPSS Report
• Generator Test EPSS Vista diagrams
• Generator Run History

 

NOTE: Before starting the configuration, the monitoring devices must be installed, communicating and connected to the relevant electric circuits. The generator and automatic transfer switch (ATS) digital and analog outputs must be connected to the equivalent inputs on the monitoring devices.

NOTE: All statuses for a specific ATS must be recorded by the same monitoring device. All statuses for a specific generator must be recorded by the same monitoring device.

You need to configure the system before you can use any of the EPSS features. The configuration includes these high-level steps:

Step 1: Setting up the monitoring devices in the PME software.

Step 2: Defining generators, ATSs, and groups in the Generator Performance Configuration tool.

Step 3: Generating Vista diagrams in the Generator Performance Configuration tool.

Step 4: Configuring and saving the EPSS Test report in Reports.

 

Step 1: Setting up the monitoring devices in the PME software:

1. Add the devices that are monitoring the generators, ATS, and load to PME, using Management Console or Device Manager.

   See EPSS devices for information on supported device types.

2. Configure the digital inputs on the devices for the generator and ATS status measurements, for each generator and ATS, with the following settings and labels:

   NOTE: PME includes ION framework templates for the generator and ATS input measurements. These templates provide a starting point for configuring ION devices to monitor generator and ATS status data. If you use ION devices to monitor these inputs, see ION device frameworks for EPSS monitoring for more information.

   ATS status signals:

   Signal	Input Setup	Label(**)
   ATS Normal	Mode: KYZ Event Log: On Event Priority: 64	ATS Normal
   ATS Test	Mode: KYZ Event Log: On Event Priority: 64	ATS Test
   ATS Emergency	Mode: KYZ Event Log: On Event Priority: 64	ATS Emergency
   ATS Power Outage(*)	Mode: KYZ Event Log: On Event Priority: 64	Power Outage

   Generator status signals:

   Signal	Input Setup	Label(**)
   Generator Stopped	Mode: KYZ Event Log: On Event Priority: 64	Gen Stop
   Generator Running	Mode: KYZ Event Log: On Event Priority: 64	Gen Run
   Generator Starting(*)	Mode: KYZ Event Log: On Event Priority: 64	Gen Start
   Emergency Power Source Available (EPA)(*)	Mode: KYZ Event Log: On Event Priority: 64	EPA Available

   (*)These signals are not required for the EPSS Test module. They can optionally be included in the EPSS report.
   (**) The labels shown in the table are recommended labels; they are recognized by PME Alarms and categorized as Asset Monitoring alarms. PME creates measurement definitions based on the digital input labels. You can use different labels if necessary.

3. Configure the analog inputs on the devices for the generator engine measurements, for each generator, with the following labels:

   NOTE: PME includes an ION framework template for the generator analog input measurements. This template provides a starting point for configuring ION devices to monitor generator engine data. If you use ION devices to monitor these inputs, see ION device frameworks for EPSS monitoring for more information.

   Signal	Label(**)
   Engine Temperature (or Coolant Temperature)	Engine Temp
   Exhaust Gas Temperature (if single exhaust)	Ex Gas Temp
   Exhaust Gas Temperature Left (if dual exhaust)	Ex Gas L Temp
   Exhaust Gas Temperature Right (if dual exhaust)	Ex Gas R Temp
   Engine Oil Pressure(*)	Engine Oil Prssr
   Other Engine related measurements, for example battery voltage(*)	<your custom label>

   (*)These signals are not required for the Generator EPSS Test module. They can optionally be included in the EPSS report.
   (**) The labels shown in the table are recommended labels. PME creates measurement definitions based on the analog input labels. You can use different labels if necessary.

4. Configure logging on the devices for the following parameters:

   NOTE: Do not use software logging for the ATS and generator status data. Software logging introduces unpredictable time delays which result in low timestamp accuracy for the logged data. Always use device on-board logging for this data.

   Parameter	Type	Channels/Msrmnts	Logging Interval
   ATS Status Signals	Digital Input Statuses	3-4	Log all ATS statuses every time one of the ATS statuses changes. NOTE: When one of the ATS statuses changes, all the ATS statuses must be logged with the same timestamp.
   Generator Status Signals	Digital Input Statuses	2-4	Log all generator statuses every time one of the generator statuses changes. NOTE: When one of the generator statuses changes, all the generator statuses must be logged with the same timestamp.
   Generator Engine Data	Analog Input Measurements	2 or more	Log engine data with a 1-minute logging interval. NOTE: Use the generator Run signal to start the logging and the Stop signal to end the data logging.
   ATS Load Data	3-Phase Power System Measurements(*)	kW tot or kVA tot	Log ATS load data with a 1-minute logging interval. NOTE: Use the ATS Test and Emergency signals to start the logging and the Normal signal to end the data logging.
   Generator Electrical Data	3-Phase Power System Measurements	Vln a,b,c,avg; Vll ab, bc,ca,avg I a,b,c,avg; kW tot; kVA tot; PF sign tot; Frequency	Log generator electrical data with a 1-minute logging interval. NOTE: Use the generator Run signal to start the logging and the Stop signal to end the data logging.

5. (Optional) Configure the device to generate a Transfer Time alarm in PME for an EPSS run. See EPSS Transfer Time alarm for details.
6. (Optional) Configure the device for remotely switching the ATS into Test mode. See Remote control of ATS Test mode for details.

Next, define the generators, ATSs, and groups in the Generator Performance Configuration tool.

Step 2: Defining generators, ATSs, and groups in the Generator Performance Configuration tool:

1. Open the Generator Performance Configuration tool.
2. On the Generators tab, add a generator, set its nameplate rating, and map the sources and measurements for the electrical, engine, and status measurements.
3. Repeat step 2 for all the generators that are part of your emergency power supply systems.
4. On the Transfer Switches tab, add an ATS, set its priority level, and map the sources and measurements for the load and status measurements.
5. Repeat step 4 for all the ATSs that are part of your emergency power supply systems.
6. (Optional) On the Equipment tab, add any additional equipment for which you want to include data in the EPSS report. Map the source and measurement for this equipment.
7. On the Groups tab, add a group representing an EPSS, and assign the generators, ATSs, and equipment that are part of the EPSS to this group.
8. Repeat step 7 for all your emergency power supply systems.

NOTE: The groups you create with the Generator Performance Configuration Tool are available for selection as inputs to the Generator Test EPSS Report. All generators and transfer switches that are defined in a group are included in the report when that group is selected. You have the option to exclude generators and transfer switches in a group from a report by selecting this option in the report inputs section.

See Generator Performance Configuration Tool with EPSS Test Module for information on how to use the tool.

Next, generate Vista diagrams in the Generator Performance Configuration tool.

Step 3: Generating Vista diagrams in the Generator Performance Configuration tool:

1. Open the Generator Performance Configuration tool.
2. Confirm that the Generators, ATSs, and Groups are defined.
3. On the Groups tab, click Generate Vista Diagrams.

See Generator Performance Configuration Tool with EPSS Test Module for information on how to use the tool.

Next, configure and save the EPSS Test report in Reports.

Step 4: Configuring and saving the EPSS Test report in Reports.

1. Open Reports in PME Web Applications.
2. Add a new Backup Power > Generator Test EPSS Report.
3. Set the report input parameters and save the report.

See Generator Test EPSS Report for information on report input parameters.
