for the UPCA and Machine Controller connectors. Pin 1 is on the
left side of the UPCA - J4 connector and on the right side of the
machine controller PCA board J1 connector. On the original
cable, the yellow wire identifies pin 1 (Fig. 1, Fig. 2).
bDisconnect the UPCA J4 MACHINE CONTROL connector. Note
that the yellow wire (pin 1) is located on the left side of the
connector (Fig. 1 & Fig. 2).
cDisconnect the Machine Controller J1 MACHINE CONTROL
connector. Note that the yellow wire (pin 1) is located on the
right side of the connector (Fig. 1 & Fig. 2).
dRemove the cable from the machine controller cable clips (Fig.2).
Discard the cable.
4Before installing the new cable, apply dielectric grease into each of
the eight connector pin sockets for both of the new machine control
cable connectors. Clean and wipe any excess grease from the
connector housing.
Note:
Use your fingertip to completely fill each pin socket with grease.
