Channel 16 of Analog Board 1 is dedicated to reading motor
amps, either through the use of the on board current trans-
former when using a 0-5 amp CT, or from an external source.
When reading motor amps directly at the P8 terminal strip
from a CT, the input signal cannot exceed 5 amps. An external
DC Ma or voltage device, may be used as an alternate method
of reading motor amps. Connect the wiring to connector
P7B as shown in the diagram below:
