(3)
Remove the temperature controller (AMM 21-61-81/401).
S 866-031
(4)
Make sure the pack has been off for 20 minutes or until it has reached ambient temperature.
E. Resistance Check Procedure
S 976-032
(1)
Measure the temperature adjacent to the applicable duct temperature sensor.
S 976-033
(2)
Write down the temperature.
S 976-034
(3)
For the duct temperature limit sensor for the flight compartment, measure the resistance from pin 21 to pin 22 on connector D454 for the temperature controller (WDM 21-61-01).
S 976-036
(4)
For the duct temperature limit sensor for the passenger cabin, measure the resistance from pin 21 to pin 22 on connector D456 for the temperature controller (WDM 21-61-01).
S 976-038
(5)
For the duct anticipator temperature sensor for the passenger cabin, measure these resistances (WDM 21-61-01):
(a)
The resistance from pin 14 to pin 15 on connector D456 for the temperature controller.
(b)
The resistance from pin 15 to pin 16 on connector D456 for the temperature controller.
S 976-040
(6)
For the duct anticipator temperature sensor for the flight
compartment, measure these resistances (WDM 21-61-01):
(a)
The resistance from pin 14 to pin 15 on connector D454.
(b)
The resistance from pin 15 to pin 16 on connector D454.
(7)
Write down the resistance in Ohms that you measure.
S 976-055
(8)
Find the temperature on Figure 601 that is nearest to the
temperature that you wrote down.
