Adding a new generator

To add a new generator:

1. On the Generator tab, click New.
2. Complete the following fields to define the generator:
   • Name - Enter a unique name to identify the generator.
   • Location - (Optional) Add information about the physical location of the generator.
   • Description - (Optional) Add information about the generator, such as make and model.
   • Electrical Data
     • Source - Select the monitoring device that records the electrical data of the generator.
     • Prime Nameplate Rating - Enter the rated generator power output. Refer to the generator's nameplate for this value.
     • Unit - Select the unit of measurement for the generator rating value.
   • Engine Temperature Data - Select the check box to enable this property. Complete the following fields:
     • Source - Select the monitoring device that records the engine temperature of the generator.
     • Measurement - Select the engine temperature measurement.
     • Unit - Select either F (for Fahrenheit) or C (for Celsius) for the temperature unit of measurement.

       NOTE: The same unit is used for the generator test Evaluation Method setting.

   • Exhaust Gas Temperature Data - Select the check box to enable this property. Complete the following fields:
     • Source - Select the monitoring device that records the exhaust gas temperature of the generator.
     • Single Exhaust or Dual Exhaust - Select whether the exhaust gas temperature is measured for a single exhaust or a dual exhaust generator.
     • Measurement - Select the exhaust gas temperature measurement.
     • Unit - Select either F (for Fahrenheit) or C (for Celsius) for the temperature unit of measurement.
   • Edit Evaluation Method - Set the evaluation method and the pass/fail criteria for generator tests. See Editing the generator Evaluation Method for more details.
   • Assign Engine Data - Associate data from the monitoring device with engine data measurements defined in the tool. See Assigning engine data for more information.

     NOTE: You can define Engine data measurements in the Edit Engine Data editor at the top of the Generators tab. See Editing Engine Data for more details.

   • Status Measurements - Configure the monitoring device and the measurements used to record the generator states.
     • Source - Select the monitoring device that records the generator states.
     • Starting - Select the check box to enable this property. This state indicates that the generator is starting. Select the measurement that provides the Starting state input, and enter the Active Value for the measurement.
     • Running - This state indicates that the generator is running. Select the measurement that provides the Running state input, and enter the Active Value for the measurement.
     • Stopped - This state indicates that the generator has stopped. Select the measurement that provides the Stopped state input, and enter the Active Value for the measurement.

     NOTE: Two stop signals could be sent from the generator controller: the initial stop signal which is followed by 3- to 5-minute cooling period, and the final stop signal after the cooling period is complete. If the generator has two stop signals, use the measurement for the first stop signal before the generator goes into the cooling mode. Do not use the stop signal after the cooling period.

     Example:

     Assume that the system has been configured with measurements of GENStarting, GENRunning, and GENStopped. You assign these measurements to the Starting, Running, and Stopped states respectively and enter 1 as the Active Value for each.

     • When the generator starts, the active value for GENStarting becomes 1, and Starting is the state for the generator.
     • When the generator is running, the active value for GENRunning becomes 1, and Running is the state for the generator.
     • When the generator stops, the active value for GENStopped becomes 1, and Stopped is the state for the generator.

     Additional notes about the Status Measurements:

     If there is only one measurement to indicate that the generator is either running or stopped, then you select that measurement for both the Running and Stopped states, and assign a different active value for each. For example, if the measurement used to indicate whether a generator is running or not is GenRunningStopped, define the states like this:

     For the Running state:

     1. Select GenRunningStopped as the measurement.
     2. Set the Active Value to 1.

        When the generator is running, the active value for GenRunningStopped is 1, and Running is the state for the generator.

     For the Stopped state:

     1. Select GenRunningStopped as the status measurement.
     2. Set the Active Value to 0.

        When the generator is stopped, the active value for GenRunningStopped is 0, and Stopped is the state for the generator.

     • Tune Signals - For each of the Starting, Running, and Stopped measurements, click the Tune Signals check box to apply tuning to the status measurement's timestamp. If Tune Signals is selected, enter the tuning signal in the Time Value +/- field. The tune signal must be between -30,000 ms and 30,000 ms. Tune signals work in conjunction with Status Measurements to accurately depict the actual sequence of events within the EPSS system. Use the signals when there are recurring inaccuracies in generator signals.

       Example: If the generator Starting measurement is consistently delayed by 40-50ms, the tune signal can be set to 45ms to ensure its accurate representation in the sequence of EPSS events.

     • Monitor for EPS Available - Select the check box to enable this property. This state indicates that the emergency power source (EPS) is available. Select the measurement that provides the EPS Available state, enter the active value for the state measurement, and enter the Required Time (Seconds). The Required Time value specifies the amount of time required to be considered a pass for a generator test evaluation.
   • Battery Waveforms - Select the check box to enable this property. Complete the following fields:
     • Source - Select the monitoring device that captures the battery voltage signature (waveform).
     • Measurement - Select the battery voltage signature (waveform capture) measurement, for example V4 Waveform.
3. Click Apply to save the changes and keep the configuration tool open. Click OK to save the changes and close the configuration tool.
4. (Optional) Repeat these steps to define other generators.
