The fifth data section displays the Analog Outputs
(AO) that can be viewed from the Service Mode. The
Analog Output signals are typically referenced to the
common (return, ground) in the system. J12-3 can also
be used as common, as well as chassis ground, or the
common terminal point on the Chiller Control Board.
See the wiring diagrams. GND on the plug. Displays
for systems 3 and 4 are skipped if the systems are not
present on the chiller. XXX is replaced with ON or
OFF in the actual display. The state of these outputs is
only viewable unless the password 9675 (ENTER)
key was entered from the initial Service Mode dis-
play with the UNIT switch in the OFF position. The
chiller will not be permitted to run when the outputs
are made active. The outputs can be programmed for
a specific % output by keying in the value and press-
ing the (ENTER) key. These messages will only be
displayed in English.
