| ||
| High Speed | Setup: The high speed Evaporator Fan is turned off, a current draw test is done | ||||
| after 10 seconds. |
|
|
| ||
Evaporator Fan |
|
|
| |||
Pass/Fail Criteria: Passes if change in current draw is within the range | ||||||
| Motors Off | |||||
| specified. Fails if AL11 or AL12 activates during test. | |||||
|
| |||||
|
|
|
|
| ||
|
| Setup: The High Speed Evaporator Fan is turned on and run for eight minutes, | ||||
|
| with all other outputs |
| |||
Supply/Return Probe | Pass/Fail Criteria: A temperature comparison is made between the return and | |||||
supply probes. |
|
|
| |||
| Test | NOTE: If this test fails, | ||||
|
| |||||
|
| (this test and the PRIMARY/ SECONDARY) pass, the display will read “P5” | ||||
|
| “PASS.” |
|
|
| |
|
| Requirements: For units equipped with secondary supply probe only. | ||||
|
| Pass/Fail Criteria: The temperature difference between primary and secondary | ||||
|
| probe (supply) is compared. |
| |||
Supply Probe Test |
| NOTE |
| |||
|
| If this test fails, | ||||
|
| and the SUPPLY/ RETURN TEST) pass, because of the multiple tests, the | ||||
|
| display will read ’P 5’ ’PASS’. |

| Requirements: For units equipped with secondary return probe only. | ||||
|
| Pass/Fail Criteria: The temperature difference between primary and secondary | ||||
|
| probe (return) is compared. |

| NOTES |
| ||
Return Probe Test | S If this test fails, | |||||
|
| tests (this test and the SUPPLY/ RETURN) pass, because of the | ||||
|
| multiple tests, the display will read “P 5,” “PASS.” | ||||
|
| S The results of | ||||
|
| clear control probe alarms. |
| |||
|
| Setup: The compressor is started. If it is the first compressor start, the | ||||
|
| compressor reliability enhancement logic (CREL) is executed, running a current | ||||
| Single Speed | draw test with the additional outputs (if installed) in the following states: | ||||

|
| Setup: Prior to this testing the ambient temperature is checked. If the ambient | ||||
|
| temperature is less than 60_F, the high speed compressor test will run first. If the | ||||
| Dual Speed | ambient temperature is greater than 60_F, or if the ambient temperature is | ||||
| invalid, the low speed compressor test will run first. Once the first compressor | |||||
| Compressor Tests | |||||
test has been completed, the switch over to the other compressor test will follow. | ||||||
(For dual speed | ||||||
| Upon entry to this test section, the high speed evaporator fan should already be | |||||
| units) | |||||
| running, if not, it is started. After the evaporator fan has run for five seconds, the | |||||
|
| |||||
|
| high speed condenser fan is started. After the condenser fan has run for five | ||||
|
| seconds, the compressor test is run. |
