NOTE
Limit Control temperature readings below 90% of the values set by thumb switches are
blanked out. Depress and release the DISPLAY switch, as required, to obtain temperature
indications.
(10)Depress the TI Limit Control POWER OFF switch.
(11)Access the Thermocouple Jack Panel and move plugs 1-4 to T53/T55/T63/64 position. Ensure that
the system is in the T53 or T64 mode (Reference FEDS operator's manual).
(12)Connect the thermocouple calibrator to connector P801 of cable 20090768-1.
(13)Depress TI Limit Control POWER ON switch.
(14)Set the Engine Oil Inlet Temperature thumb switches on the Limit Control Panel to 300 F.
(15)Adjust the calibrator to the temperature settings in the table above. Record the TI reading and verify
that the TI Limit Control Panel indications are within the tolerance limits. Adjust as necessary.
36. Temperature Limit Control - Engine Oil Delta Temperature
a. Performance Check
(1) T700 Procedure: Connect Temperature Calibrator to P57. Connect a thermocouple to P56. Adjust
thumbwheel switch setting to 150 for Oil Δ Temperature. Input the temperature set point values listed
below and note the TI indications.
(2) T53/55/63/64 Procedure: Connect Calibrator to P802. Connect a thermocouple at P801. Adjust
thumbwheel switch setting to 150 for Oil Δ Temperature. Input the temperature set point values listed
below and note the TI indications.

37. Dynamometer Lube Inlet Temperature (0 to 200 F)
a. Performance Check
(1) Ensure that plug 3 of the Thermocouple Jack panel is in the T700 position. Ensure that the system is
in the T700 mode (Reference FEDS operator's manual).
(2) Connect the thermocouple calibrator to J20 (+), Dyno Tank, using Type Jx thermocouple wire.
(3) Depress the TI Limit Control POWER ON switch.
(4) Adjust the thermocouple calibrator output for 32 F.
(5) Verify that the TI Limit Control Panel reading is between 29 and 35 F. Adjust potentiometer R-33 as
necessary.
(6) Set the TI Limit Control DYNAMOMETER LUBE INLET TEMPERATURE / THUMBWHEEL switches
to 200.
(7) Adjust the calibrator output to the temperatures listed below. At each temperature, verify that the TI
readings are within tolerance limits listed in the table below. Adjust TI as necessary.
