Detecting deviations and faults when Sample Clauses

Detecting deviations and faults when comparing with nominal behaviour To detect deviations in machine components, where the external environment and applications contribute less than in the previous example, Volvo CE would like to compare the operation variables with an average or nominal behaviour gained from the complete machine fleet of the same model. The nominal behaviour is analysed and following sent out to the machines in the form of thresholds etc. depending on usage profile. This help to calibrate the fault detection routines on each machine. In the Smart Vortex project, an example where the pressure build up in transmission clutches will be studied. If the pressure build up is not correct, the results will be slippage which must be avoided. Any deviations from the nominal behaviour can help to indicate that slippage might occur in the future. The following data stream is needed to study the gear shift from forward first gear to forward second gear:  Show the average of the 10 latest gear shifts F1-F2 for the time data of control valve downstream pressure starting at gear switch and ending 1 s after clutch speed difference is zero. Given this type of data stream for all possible gear switch combinations:  Show the group of 10% machines of a given model that deviates the “most” from the others in terms of all the pressure build up data streams A similar case is the deviation of gear shift comfort among machines. This demands on-board Fast Fourier Transformation (FFT) filtering:  Show the average of the 10 latest gear shifts F1-F2 for the frequency range of 1-3 Hz for FFT filtered time data of longitudinal accelerometer starting at gear switch and ending 1 s after clutch speed difference is zero.  Show the group of 10% machines of a given model that deviates the “most” from the others in terms of all the FFT filtered longitudinal acceleration data streams

Detecting deviations and faults when comparing with nominal behaviour The deviating groups of machines could even be hierarchic, if the deviating groups in the last section were retrieved from each context group. In this way, the deviating machines can be studied in more detail using interactive fault diagnosis: • Given a deviating machine with respect to transmission clutch pressure build up data stream, initiate a remote interactive fault diagnosis session. Operator secures safety. • Show in real-time in a flow diagram the pressure of all transmission clutches with sampling frequency 50 Hz. At the same time display the reference pressure from transmission Electronic Control Unit (ECU) • The mechanic demands actuation of valves according to given scheme and/or manually. Show deviation of valve position to reference signal. • Play sound of mobile microphone with upper frequency limit from database. Machine operator places microphone at suitable position.

  • Environmental Conditions A Phase I environmental site assessment (or update of a previous Phase I and or Phase II environmental site assessment) and, with respect to certain Mortgage Loans, a Phase II environmental site assessment (collectively, an “ESA”) meeting ASTM requirements conducted by a reputable environmental consultant in connection with such Mortgage Loan within 12 months prior to its origination date (or an update of a previous ESA was prepared), and such ESA (i) did not identify the existence of Recognized Environmental Conditions (as such term is defined in ASTM E1527-05 or its successor, hereinafter “Environmental Condition”) at the related Mortgaged Property or the need for further investigation, or (ii) if the existence of an Environmental Condition or need for further investigation was indicated in any such ESA, then at least one of the following statements is true: (A) an amount reasonably estimated by a reputable environmental consultant to be sufficient to cover the estimated cost to cure any material noncompliance with applicable Environmental Laws or the Environmental Condition has been escrowed by the related Mortgagor and is held or controlled by the related lender; (B) if the only Environmental Condition relates to the presence of asbestos-containing materials, radon in indoor air, lead based paint or lead in drinking water, the only recommended action in the ESA is the institution of such a plan, an operations or maintenance plan has been required to be instituted by the related Mortgagor that can reasonably be expected to mitigate the identified risk; (C) the Environmental Condition identified in the related environmental report was remediated, abated or contained in all material respects prior to the date hereof, and, if and as appropriate, a no further action, completion or closure letter or its equivalent, was obtained from the applicable governmental regulatory authority (or the Environmental Condition affecting the related Mortgaged Property was otherwise listed by such governmental authority as “closed” or a reputable environmental consultant has concluded that no further action or investigation is required); (D) an environmental policy or a lender’s pollution legal liability insurance policy that covers liability for the Environmental Condition was obtained from an insurer rated no less than “A-” (or the equivalent) by Xxxxx’x, S&P and/or Fitch; (E) a party not related to the Mortgagor was identified as the responsible party for the Environmental Condition and such responsible party has financial resources reasonably estimated to be adequate to address the situation; or (F) a party related to the Mortgagor having financial resources reasonably estimated to be adequate to address the situation is required to take action. To Seller’s knowledge, except as set forth in the ESA, there is no Environmental Condition at the related Mortgaged Property.

  • Inspections and Testing Each Interconnected Entity shall perform routine inspection and testing of its facilities and equipment in accordance with Good Utility Practice as may be necessary to ensure the continued interconnection of the Customer Facility with the Transmission System in a safe and reliable manner. Each Interconnected Entity shall have the right, upon advance written notice, to request reasonable additional testing of an Interconnected Entity’s facilities for good cause, as may be in accordance with Good Utility Practice.

  • Inspections and Tests 26.1 The Supplier shall at its own expense and at no cost to the Procuring Entity carry out all such tests and/or inspections of the Goods and Related Services as are specified in the SCC.

  • Technical Standards Applicable to a Wind Generating Plant i. Low Voltage Ride-Through (LVRT) Capability A wind generating plant shall be able to remain online during voltage disturbances up to the time periods and associated voltage levels set forth in the standard below. The LVRT standard provides for a transition period standard and a post-transition period standard.

  • Trunk Forecasting Requirements 14.2.1 Initial trunk forecast requirements. At least ninety (90) days before initiating interconnection in a LATA, Alltel shall provide Verizon a two (2)-year traffic forecast that complies with the Verizon Interconnection Trunking Forecast Guide, as revised from time to time. This initial traffic forecast will provide the amount of traffic to be delivered to and from Verizon over each of the Interconnection Trunk groups in the LATA over the next eight (8) quarters.

  • Initial Forecasts/Trunking Requirements Because Verizon’s trunking requirements will, at least during an initial period, be dependent on the Customer segments and service segments within Customer segments to whom CSTC decides to market its services, Verizon will be largely dependent on CSTC to provide accurate trunk forecasts for both inbound (from Verizon) and outbound (to Verizon) traffic. Verizon will, as an initial matter, provide the same number of trunks to terminate Reciprocal Compensation Traffic to CSTC as CSTC provides to terminate Reciprocal Compensation Traffic to Verizon. At Verizon’s discretion, when CSTC expressly identifies particular situations that are expected to produce traffic that is substantially skewed in either the inbound or outbound direction, Verizon will provide the number of trunks CSTC suggests; provided, however, that in all cases Verizon’s provision of the forecasted number of trunks to CSTC is conditioned on the following: that such forecast is based on reasonable engineering criteria, there are no capacity constraints, and CSTC’s previous forecasts have proven to be reliable and accurate.

  • Use of Trunk Forecasts Trunk forecasts provided pursuant to this Agreement must be prepared in good faith but are not otherwise binding on CBB or Verizon.

  • GEOGRAPHIC AREA AND SECTOR SPECIFIC ALLOWANCES, CONDITIONS AND EXCEPTIONS The following allowances and conditions shall apply where relevant: Where the company does work which falls under the following headings, the company agrees to pay and observe the relevant respective conditions and/or exceptions set out below in each case.

  • Additional Requirements for Sleeping Rooms The Contractor shall provide departing Attendees a secured area for storing belongings.

  • Interconnection Facilities Engineering Procurement and Construction Interconnection Facilities, Network Upgrades, and Distribution Upgrades shall be studied, designed, and constructed pursuant to Good Utility Practice. Such studies, design and construction shall be based on the assumed accuracy and completeness of all technical information received by the Participating TO and the CAISO from the Interconnection Customer associated with interconnecting the Large Generating Facility.
