2. FACTORY ACCEPTANCE TEST (FAT) PLAN

2.1 OVERVIEW

The FAT plan described in this section is designed to verify that the GOS meets the requirements as laid out in SPEC-0080 GOS Design Requirements Document (DRD) at the NSO Boulder Lab (the “factory”). For this reason the GOS will be tested standalone and interfaces to the facility will be simulated. Inspections will be performed by DKIST personnel with appropriate training (i.e. mechanical inspections done by mechanical engineer/technician). Manual tests will be run using engineering GUI widgets, whereas automated tests can be run using Jython scripts built with the DKIST Test Applications Framework (TAF). Testing of the GOS optics is not covered in this document. Instead, please refer to PROC-0027 Polarization Optics Test Plan.

2.2 TEST DESCRIPTIONS

This section describes the steps necessary to verify all requirements where the verification method was listed as either inspection or manual-test in the PA&C Compliance Matrix CMX-0021. Those tests with a verification method of auto-test include an automated test (see PA&C source tree $ATST/src/jython/atst/pac/tests) which includes details of what the requirement is, what the test steps are and what conditions have to be met for the test to be considered successful.

2.3 TEST CONFIGURATION

Most of the requirement verification relies on the same test configuration. Rather than repeat that information for each requirement the standard configuration is captured here. Verifications which rely on a non-standard configuration call that out in their pre-conditions section.

2.3.1 Environment

NSO Boulder Lab, N130 Modular clean room, class 100,000 Temperature range: 68-70 degrees Celsius GOS assembly mounted on two 1 ton saw horses Other lab equipment used as noted in test details

GOS FAT Plan


2.3.2 Mechanical

Deviations of the test configuration to the final integrated configuration at the summit are indicated in the following table:

Test Configuration Integrated Final Configuration

Fittings Compression NPT

Tubing Tygon Steel‐braided PTFE Core

Mount Two 1 ton saw horses GOS frame mounted to TMA per ICD interface

Temperature 21‐25 deg C Varies between 0‐20 deg C

Pump 3 GPM Recirculator Facility Pump

Table 1: Deviations from Final Integrated Configuration

Further details are included in the following sections for specific test configurations.

2.3.3 Electrical

The GOS electronics will be installed in the OSS rack in the NSO, Boulder lab. The bulkhead interface on the OSS rack and on the GOS frame will be used in the testing. Electrical connections to the GOS as tested in the lab are compliant with the ICD 1.1 – 3.1.1 TMA to PA&C and DKIST-DWG-00342. GIS system is not available for testing, therefore the interface between the GIS and GOS as described in ICD 3.1.1 – 4.5 PA&C to GIS will be tested at the DKIST summit. For our purposes, the GOS Safe Torque Off (STO) function was tested independently to ensure proper functioning.

2.3.4 Software

Software/Hardware Configuration: Operating System – the operating system will be CentOS 7.3 running kernel version 3.10 Common Services – the Canary 10 release will be used Java – Java version 1.8 as required by the use of Canary 10 The PACCS release tagged as “beta_rc1” in the ATST CVS repository The PACCS software is installed on the PACCS computer according to the software manual The PACCS software and GUI will run on the PACCS control computer The CSF services and database will be hosted on nsocsf.int.colorado.edu Network connectivity between all machines listed above is through NetGear 1Gbit switch

Unless otherwise stated the GOS software and its dependencies should be installed as per the instructions in PACCS User’s Manual. The PACCS release will include the file $ATST/admin/pac/pacSite.config.fat and that file should be used for configuring the PACCS for the FAT. See SPEC-0022 for details on the pkgDevel framework and how to configure a system and the PACCS Maintenance Manual for an explanation of the PACCS pkgDevel options.

GOS FAT Plan


The PACCS should be in the running state for all of its tests and unless otherwise noted may remain running between tests. The PACCS and its GUI should be started following the instructions in PACCS User’s Manual. The PACCS requires an event from the TCS in order for the occulter tracking to work properly. Thus the TCS will be installed on another machine on the same CSF network and configured to produce the tracking event per ICD 3.1.1 – 4.4 PA&C to TCS. .

2.4 TESTS

The following sub-sections describe the lab acceptance tests that will be performed:
