Chapter 3 Part Replacement Procedures
1. Cut and remove the appropriate sizing resistor(s) (if necessary) from the
pulse transformer board based on the drive size. See Ta b le 13
or Tab l e 14
for the appropriate configuration.
Sizing Resistor Configuration
Table 1 3 and Table 1 4 indicate the value of the designated resistor (R1 - R5)
when left in place on the pulse transformer board, or indicate “Remove” when
the resistor should be cut off and removed from the board. “–” indicates that
this resistor is not contained on the pulse transformer board for the designated
drive size.
Table 13 - 230V AC Input Drives
Table 14 - 460V AC Input Drives
2. Connect the leads of the multimeter to pins 13 and 14 of connector XR
on the pulse transformer board (polarity is not important) and, using
the TA potentiometer on the lower right corner of the pulse transformer
circuit board, set the total resistance (RTA) to the appropriate value as
indicated in Ta b le 15
or Tabl e 16 in the Total Resistance Values section
on page 72
