All other jumper selections remove the +15V dc power from the pins of
connectors CN14F, CN15F, and CN16F on the optional feedback module.
There are three variable resistors (pots) located on the optional feedback
module. Use these pots to adjust the +5V dc output to the non-motor
mounted feedback devices. Figure 4B.21 shows the optional feedback
module pots,corresponding connectors and lists the pots and their
corresponding connectors and pin numbers on the optional feedback module.

Adjust the pots so that the +5V dc voltage of pins 14, 15, and 16 at the
feedback device end of the feedback cable is within the operating voltage
range of the non-motor mounted feedback device. The pot adjustment
depends on the:
length of the cable running from the optional feedback module to the
non-motor mounted feedback devices
+5V dc operating voltage range of the non-motor mounted feedback
devices
If adjusting the pots does not adjust the +5V dc output so that it falls within
the operating voltage range of the non-motor mounted feedback device, an
external +5V dc power supply is required or the feedback device cable
must be shortened.
