[. . . ] 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. 6_C (60_F), the set point is changed to 15. 6_C, and a 180--minute timer is started. The left display will read "P8--0. " The control will then heat the container until 15. 6_C is reached. If the container temperature is above 15. 6_C 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. 6_C (60_F). Setup: The set point is changed to 0_C (32_F), 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 return probe temperature error (supply temperature minus set point) until the timer expires. The return probe temperature will be sampled at least once each minute starting at the beginning of P10--2. Pass/Fail Criteria: If the average recorded temperature is within +/-- 1. 6_C (+/-- 2. 9) of set point, the test passes. If the average temperature is outside of the tolerance range or if the DataCORDER return temperature probe is invalid, the test fails and the control probe temperature will be recorded as --50. 0_C. P10--2 will auto--repeat by starting P10--0 over. 3--30 P8--0 Perishable Mode Heat Test P8--1 Perishable Mode Pulldown Test P8--2 Perishable Mode Maintain Temperature Test P9--0 Defrost Test P10--0 Frozen Mode Heat Test Frozen Mode P10--1 Pulldown Test Frozen Mode P10--2 Maintain Temperature Test T-340 Table 3- DataCORDER Function Code Assignments -8 NOTE Inapplicable Functions Display "-- -- -- -- -- " To Access: Press ALT. dC1 dC2 dC3--5 dC6--13 dC14 TITLE Recorder Supply Temperature Recorder Return Temperature DESCRIPTION Current reading of the supply recorder sensor.

Ensure that the unit power is off AND that the unit power plug is disconnected. Open control box, see Figure 6--26 and remove low voltage shield. If using factory provisioned wiring, remove the circuit breaker panel, with circuit breaker, from the control box. [. . . ]
