TM5-6115-593-34 NAVFAC P-8-631-34 TO-35C2-3-463-2 d. Speed Switch Disassembly.  Refer to figure 13-1, cut safety wire and disassemble in sequence of index numbers observing the following: (1) If either the rotor assembly, the body assembly, or the spacer are damaged or defective, replace, defective part. Reassembly. is the reverse order of figure 13-1 sequence of index numbers.  Refasten with lockwire after readjustment. (2) Repeat the test and adjustment procedures in paragraph C, above. (3) Refer to Operator/Crew and Organizational Maintenance manual and install speed switch. 13-4.  ELECTRONIC TYPE SPEED SWITCH (Code "B"). To test speed switch refer to figure 13-3 and the following: a.General.  The electronic speed switch performs in the same manner as described in paragraph 13-3a except, rather than operating by centrifugal force the switch operates electronically. Output switch contacts are rated for 10 amps.  Elements S9-1 and S9-2 reset anywhere between 0 and 100 rpm (typically set for 50 rpm) below actuation speed. b.Speed Switch Removal.  The electronic speed switch is removed in the identical manner to the centrifugal switch referred to in the Operator/Crew and Organizational Maintenance Manual. c. Speed Switch Tests (1) With an ohmmeter on the RX1 scale, verify that the switch contacts are as shown in figure 13-3. (2) Connect a variable speed drive device to the speed switch drive.  The drive device must have a tachometer in order to determine the device speed in rpm's. (3) Apply 24V DC (+) to pins A,  D and F and (-) to pin I. (4) Start variable drive and gradually increase speed.  Using a DC voltmeter (0-50V DC minimum scale) across pins B (+) and (-) verify that voltage goes to zero between 290 and 310 rpm.  At this speed voltage at pin C should be at 24V DC. (5) Reduce speed gradually and verify that voltage at pin C goes to zero volts 0-100 rpm lower than pick-up rpm in step 4.  At this speed voltage at pin B will return to 24V DC. (6) With voltmeter between pins E (+) and I (-), zero voltage should be indicated.  Increase speed and verify that pin E voltage goes to 24V DC between 590 and 610 rpm. (7) Reduce speed gradually and verify that pin E voltage returns to zero volts 0-100 rpm lower than pick-up rpm in step 6. (8) With voltmeter (+) connected to pin J, zero volts should be indicated.  Gradually increase speed and verify that voltage goes to 24V DC between 1100 and 1150 rpm. At this speed, voltage at pin H will be at zero volts. (9) Reduce drive speed to zero rpm.  Voltage at pin H should remain at zero and voltage at pin J should remain at 24V DC until the blue reset button is depressed. (10) All trip speed settings are factory set and cannot be field adjusted. d. Speed Switch Disassembly Since there are nib moving parts except the speed switch drive with virtually no load applied, disassembly is not required since wear is practically non-existent. 13-5.  STARTER ASSEMBLY (Code A).  To service the components of the starter 13-4
