Safety--1 SPECIFIC WARNING AND CAUTION STATEMENTS . 1--1 1. 4. 6 Communications Interface Module . 1--2 1. 4. 16 Upper Air (Fresh Air Make Up) . [. . . ] Pass/Fail Criteria:The test fails immediately if: --all three sensors are not configured or are invalid. --the ambient temperature or return air temperature sensors are invalid at the start of the test. The test fails if: --the high pressure switch if open at the start of the test. --the high pressure switch fails to open within 15 minutes. --a valid discharge temperature exceeds 137. 78 C (280 F). --a valid discharge pressure or valid condensing pressure exceeds 390 psig. The test passes if the high pressure switch opens within the 15 minute time limit and before any of the valid and configured sensors exceed their limits. Requirements: Test P7--0 must pass for this test to execute. Setup: The condenser fan is started and a 60 second timer is started. Pass/Fail Criteria: Passes the test if the high pressure switch (HPS) closes within the 60 second time limit, otherwise, it fails. Discharge Thermistor Test P7--0 High Pressure Switch Open P7--1 High Pressure Switch Closed 3--29 T-340 Table 3- Controller Pre-7 -trip Test Codes (Sheet 4 of 4) Setup: If the container temperature is below 15. 6C (60F), the set point is changed to 15. 6C, and a 180--minute timer is started. The left display will read "P8--0. " The control will then heat the container until 15. 6C is reached. If the container temperature is above 15. 6C at the start of the test, then the test proceeds immediately to test P8--1 and the left display will change to "P8--1. " Pass/Fail Criteria: The test fails if the 180 minute timer expires before the control temperature reaches set point. The display will read "P8--0, " "FAIL. " Requirements: Control temperature must be at least 15. 6C (60F). Setup: The set point is changed to 0C (32F), and a 180--minute timer is started. The left display will read "P8--1, " the right display will show the supply air temperature. The unit will then start to pull down the temperature to the 0C set point. Pass/Fail Criteria: The test passes if the container temperature reaches set point before the 180 minute timer expires. Requirements: Test P8--1 must pass for this test to execute. This test is skipped if the DataCORDER is not configured or not available. The unit will be required to minimize control temperature error (supply temperature minus set point) until the timer expires. The control temperature will be sampled at least once each minute starting at the beginning of P8--2. [. . . ] Locate, wires CB21/CIA3, CB22/CIA5 and CB23/CIA7 that have been tied back in the wire harness. Remove the protective heat shrink from the ends of the wires. d. Attach three wires CB21/CIA3, CB22/CIA5 and CB23/CIA7 to the CIM at connection CIA. g. Locate connectors CIA and CIB, remove plugs if required, and attach to the module. [. . . ]
