|
| Requirements: Control temperature must be at least 60_F. |
|
|
|
| Setup: The set point is changed to 32_F, and a 180 minute timer is started. The |
|
|
Perishable Mode | left display will read |
|
| |
The unit will then start to pull down the container temperature to the 32_F set |

Pull Down Test |
|

| point. |
|
| |
|
|
|
| |
|
| Pass/Fail Criteria: The test passes if the container temperature reaches set |
|
|
|
| point before the 180 minute timer expires. |
|
|
|
| Requirements: Test |
|
|
|
| Setup: The left display will read |
|
|
|
| air temperature. A 60 minute timer is started. The unit will be required to |
|
|
|
| maintain the 32_F temperature to within + or |
|
|
|
| DataCORDER recording is executed. The recorder supply probe temperature |
|
|
|
| running total (and its associated readings counter) will be zeroed out for the |
|
|
| Perishable Mode | remainder of the recording period at the start of this test, so that the actual value |
|
|
Maintain | recorded in the DataCORDER will be an average of only this test’s results. Once |
|
| |
| Temperature Test | a recording interval is complete, the average recorder supply temperature will be |
|
|
|
| recorded in the DataCORDER, as well as stored in memory for use in applying |
|
|
|
| the test pass/fail criteria. |
|
|
|
| Pass/Fail Criteria: If the recorded temperature is within |
|
|
|
| from test start to DataCORDER recording, the test passes. If the average |
|
|
|
| temperature is outside of the tolerance range at the DataCORDER recording, the |
|
|
|
| test fails. |
|
|
|
|
|
|
|
|
| Setup: The defrost temperature sensor (DTS) temperature will be displayed on |
|
|
|
| the left display. The right display will show the supply air temperature. The unit |
|
|
|
| will run FULL COOL for 30 minutes maximum while the DTS sensor temperature |
|
|
|
| is above 10_C. Once the DTS is below 10_C, the unit simulates defrost by |
|
|
|
| running the heaters for up to two hours, or until the DTS senses the temperature |
|
|
Defrost Test | above 25.6_C. |
|
| |
Pass/Fail Criteria: The test passes if DTS is sensed above 25.6_C before a two |
|
| ||
|
|
|
| |
|
| hour timer times out. The test fails if DTS does not go below 10_C after 30 |
|
|
|
| minutes of full cooling, and/or the heater termination thermostat (HTT) is open |
|
|
|
| when the DTS is below 10_C. The test also fails if the HTT opens anytime during |
|
|
|
| the defrost cycle and/or the return air temperature exceeds 120_F anytime |
|
|
|
| during the heat cycle. |
|
|
|
| 3 | ||
|
| Setup: After completion of the DTS test, the set point will be set to 7_C (45_F). |
| |
Frozen Mode |
| SECTION | ||
when the container temperature reaches set point, or if the container |
| |||
|
| The left display will read “P100,” and if the container temperature is below 45_F, |
|
|
|
| will continue this display until the container temperature is raised to set point. |
|
|
|
| The left display will change to “P101” and execute the frozen pull down test |
|
|
| (Setup) Test | temperature initially was greater than or equal to set point. The maximum time |
|
|
|
| allowed in heat mode is one hour. |
|
|
|
| Pass/Fail Criteria: If this time limit is exceeded, the test fails. There will be no |
|
|
|
| pass indication for this test. However, if the test fails the display will read “P100,” |
|
|
|
| “FAIL.” |
