Accounting Policies [Abstract]
Computer Software Developed for Internal Use	Computer Software Developed for Internal Use Computer software developed for internal use is capitalized in accordance with provisions of the Accounting Standards Codification, or ASC, Topic 350-40, Intangibles Goodwill and Other—Internal Use Software. The Company capitalizes direct costs incurred to develop internal-use software during the application development stage after determining software technological requirements and obtaining management approval for funding projects probable of completion. Capitalization of the internal-use software development costs ceases upon substantially completing the project and placing the software into service based on its intended use. During the nine months ended June 30, 2016, the Company capitalized direct costs of $2.9 million associated with development of software for its internal use which are included within "Property, plant and equipment, net" in the accompanying unaudited Consolidated Balance Sheets. There were no internal-use software development costs as of September 30, 2015.
Deferred Financing Costs	Deferred Financing Costs The Company records commitment fees and other costs directly associated with obtaining line of credit financing as deferred financing costs which are presented within "Other assets" in the accompanying unaudited Consolidated Balance Sheets. Deferred financing costs are amortized over the term of the related financing arrangement and included in interest expense in the accompanying unaudited Consolidated Statements of Operations. During the three and nine months ended June 30, 2016, the Company incurred $0.7 million in deferred financing costs associated with obtaining line of credit financing. Amortization expense of approximately $12,000 during the three and nine months ended June 30, 2016 was included in interest expense in the accompanying unaudited Consolidated Statements of Operations. Please refer to Note 8, “Line of Credit”for further information on this arrangement.
Use of Estimates	Use of Estimates The preparation of unaudited consolidated financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates are associated with accounts receivable, inventories, goodwill, intangible assets other than goodwill, long-lived assets, derivative financial instruments, deferred income taxes, warranty obligations, revenue recognized using the percentage of completion method, pension obligations and stock-based compensation expense. The Company bases its estimates on historical experience and various other assumptions, including in certain circumstances, future projections that management believes to be reasonable under the circumstances. Although the Company regularly assesses these estimates, actual results could differ from those estimates. Changes in estimates are recorded in the period in which they occur and become known.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In June 2016, the Financial Accounting Standards Board, or FASB, issued a new accounting guidance for reporting credit losses. The new guidance introduces a new "expected loss" impairment model which applies to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables, loans, held-to-maturity debt securities and other financial assets. Entities are required to estimate expected credit losses over the life of financial assets and record an allowance against the assets' amortized cost basis to present them at the amount expected to be collected. Additionally, the guidance amends the impairment model for available for sale debt securities and requires entities to determine whether all or a portion of the unrealized loss on such debt security is a credit loss. The guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019. Early adoption of the newly issued guidance is permitted for fiscal years, and interim periods within those years, beginning after December 15, 2018. The standard should be applied as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. The Company expects to adopt the guidance during the first quarter of fiscal year 2021 and is currently evaluating the impact of this guidance on its financial position and results of operations. In May 2016, the FASB issued an amendment to the revenue recognition guidance released in May 2014. The amendment is intended to reduce the cost and complexity of applying the revenue recognition guidance and result in a more consistent application of the revenue recognition rules. The amendment clarifies the implementation guidance on collectibility, non-cash consideration and the presentation of sales and other similar taxes, as well as transitional guidance related to completed contracts. The guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017 and should be applied at the time of the adoption of the revenue recognition guidance issued in May 2014. Early adoption of the newly issued guidance is not permitted. The Company expects to adopt the guidance during the first quarter of fiscal year 2019 and is currently evaluating the impact of this guidance on its financial position and results of operations. In April 2016, the FASB issued an amendment to the revenue recognition guidance released in May 2014. The amendment clarifies the implementation guidance on identifying performance obligations and licensing. Specifically, the amendment reduces the cost and complexity of identifying promised goods or services and improves the guidance for determining whether promises are separately identifiable. The amendment also provides implementation guidance on determining whether an entity's promise to grant a license provides a customer with either a right to use the entity's intellectual property (which is satisfied at a point in time) or a right to access the entity's intellectual property (which is satisfied over time). The guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017 and should be applied at the time of the adoption of the revenue recognition guidance issued in May 2014. Early adoption of the newly issued guidance is not permitted. The Company expects to adopt the guidance during the first quarter of fiscal year 2019 and is currently evaluating the impact of this guidance on its financial position and results of operations. In March 2016, the FASB issued an amendment to the accounting guidance to simplify accounting for share-based payment awards issued to employees. The amendment requires recognition of excess tax benefits or deficiencies within income tax expense or benefit and changes their presentation requirements on the statement of cash flows. Additionally, the entity can make an accounting policy election to either estimate the number of awards that are expected to vest, consistent with the current accounting guidance, or account for forfeitures as they occur. The guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. Early adoption of the newly issued guidance is permitted. The Company expects to adopt the guidance during the first quarter of fiscal year 2018 and is currently evaluating the impact of this guidance on its financial position and results of operations. In March 2016, the FASB issued an amendment to the revenue recognition guidance released in May 2014. The amendment clarifies the application of the principal versus agent guidance, identification of the units of accounting, as well as application of the control principle to certain types of arrangements within the scope of the guidance. The guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017 and should be applied at the time of the adoption of the revenue recognition guidance issued in May 2014. Early adoption of the newly issued guidance is not permitted. The Company expects to adopt the guidance during the first quarter of fiscal year 2019 and is currently evaluating the impact of this guidance on its financial position and results of operations. In February 2016, the FASB, issued a new accounting guidance for reporting lease transactions. In accordance with provisions of the newly issued guidance, a lessee should recognize at the inception of the arrangement a right-of-use asset and a corresponding lease liability initially measured at the present value of lease payments over the lease term. For finance leases, interest on a lease liability should be recognized separately from the amortization of the right-of-use asset, while for operating leases, total lease costs are recorded on a straight-line basis over the lease term. For leases with a term of twelve months or less, a lessee is permitted to make an accounting policy election by class of underlying assets to forgo a recognition of right-of-use assets and corresponding lease liabilities and record a lease expense on a straight-line basis. Entities should determine at the inception of the arrangement whether a contract represents a lease or contains a lease which is defined as a right to control the use of identified property for a period of time in exchange for consideration. Additionally, entities should separate the lease components from the non-lease components and allocate the contract consideration on a relative standalone price basis in accordance with provisions of ASC Topic 606, Revenue from Contracts with Customers. The guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018 and should be adopted via a modified retrospective approach with certain optional practical expedients that entities may elect to apply. The Company expects to adopt the guidance during the first quarter of fiscal year 2020 and is currently evaluating the impact of this guidance on its financial position and results of operations. In November 2015, the FASB issued an amendment to the accounting guidance to simplify the presentation of deferred income tax assets and liabilities in a statement of financial position. Deferred income tax assets, net of a corresponding valuation allowance, and liabilities related to a particular tax-paying component of an entity within a particular tax jurisdiction shall be offset and presented as a single noncurrent amount in a statement of financial position. Deferred income tax assets and liabilities attributable to different tax-paying components of an entity or different tax jurisdictions shall not be offset and be presented separately. The guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. Early adoption is permitted. The guidance can be adopted via either a prospective or a retrospective approach for all deferred income tax assets and liabilities presented in a statement of financial position. The Company expects to adopt this guidance during the first quarter of fiscal year 2018 and is currently evaluating the impact of this guidance on its financial position and results of operations. In September 2015, the FASB issued a new accounting guidance to simplify the presentation of measurement-period adjustments recognized in business combinations. Measurement-period adjustments will no longer be recognized by the acquirer retrospectively and will be recorded by the acquirer during the period in which they were determined. The guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015 and should be applied prospectively to the adjustments that occur after the effective date of the guidance. Early adoption is permitted for the financial statements that have not been issued, and the Company adopted the guidance during the first quarter of fiscal year 2016 to simplify the presentation of the measurement period adjustments in its consolidated financial statements. During the six months ended March 31, 2016, the Company recorded a measurement period adjustment of $1.1 million related to the acquisition of Contact Co., Ltd and recognized its impact in the accompanying Consolidated Balance Sheets as of the period then ended in accordance with the provisions of the newly adopted guidance. There was no impact on the results of operations during the six months ended March 31, 2016 as a result of this adjustment. This adjustment would have been applied retrospectively and recognized as a reclassification in the accompanying Consolidated Balance Sheets as of September 30, 2015 in accordance with provisions of the previous guidance. In August 2015, the FASB issued an amendment to the accounting guidance which clarified the presentation and subsequent measurement of debt issuance costs related to line of credit arrangements based on the SEC's Staff announcement made in June 2015. In accordance with the guidance, debt issuance costs related to line of credit arrangements can be presented as an asset and subsequently amortized ratably over the term of the arrangement, regardless of whether there are any outstanding borrowings on the arrangement. The guidance became effective upon its issuance and was adopted by the Company during the fourth quarter of fiscal year 2015. The adoption of the guidance did not have an impact on the Company's financial position and results of operations. In February 2015, the FASB issued an amendment to the accounting guidance for consolidations of financial statements by changing the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. The guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015. Early adoption is permitted. The guidance can be adopted either via a full retrospective approach or a modified retrospective approach by recording a cumulative-effect adjustment to beginning equity in the period of adoption. The Company expects to adopt the guidance during the first quarter of fiscal year 2017. The Company is currently evaluating the impact of the guidance on its financial position and results of operations. In January 2015, the FASB issued new accounting guidance to simplify income statement classification by removing the concept of extraordinary items from Generally Accepted Accounting Principles, or GAAP. As a result, items that are both unusual in nature and infrequent in occurrence will no longer be separately reported net of tax after the results of continuing operations. The guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015 and can be adopted retrospectively or prospectively based on an entity's election. Early adoption is permitted. The Company expects to adopt the guidance during the first quarter of fiscal year 2017. The adoption of the guidance is not expected to have a material impact on its financial position and results of operations. In May 2014, the FASB issued new accounting guidance for reporting revenue recognition. The guidance provides for the recognition of revenue when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. A five-step process set forth in the guidance may require more judgment and estimation within the revenue recognition process than the current GAAP, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. The guidance was initially effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. In August 2015, the FASB issued an amendment deferring the effective date of the guidance by one year. The guidance should be adopted retrospectively either for each reporting period presented or via recognizing the cumulative effect at the date of the initial application. Early adoption is permitted only as of annual reporting periods, including the interim periods, beginning after December 15, 2016. The Company expects to adopt the guidance during the first quarter of fiscal year 2019 and is currently evaluating the impact of this guidance on its financial position and results of operations. In April 2014, the FASB issued an amendment to the accounting guidance for reporting discontinued operations. The amended guidance raises the threshold for disposals to qualify as a discontinued operation by requiring a component of an entity that is held for sale, or has been disposed of by sale, to represent a strategic shift that has or will have a major effect on operations and financial results. A strategic shift could include the disposal of a major line of business, a major geographical area, a major equity method investment or other major parts of an entity. In addition, the guidance allows companies to have significant continuing involvement and continuing cash flows with the discontinued operation. The guidance became effective for fiscal years, and interim periods within those years, beginning on or after December 15, 2014 and is applied prospectively. The Company adopted the guidance during the first quarter of fiscal year 2016. The adoption of the guidance did not have an impact on the Company's financial position and the results of operations.
