Digital Output Connections; Table 24 - Digital Output Connections - York YCAV0267E Installation Operation & Maintenance

MICRO PANEL
TABLE 24 lists the digital outputs and the plug/termi-
nals of the circuit board they originate from. Not all of
the outputs will be used on every unit. Signal levels
may be 12VDC, 120VAC, or a dry contact (no voltage)
closure). 120VAC signals typically may show only
one connection point; the other will be neutral (Wire
2). Outputs which reference multiple boards, such as
"Chiller Control Board / Relay Board 1" indicate the
signal originates on the Chiller Control Board as a 0-
12VDC digital signal (example: J9-1) that is then fed
to the Relay board and output as a dry contact closure
between TB1-20 and 19. In this case, outputs from both
boards are called out in the table.

The 0-120VAC single digital outputs from the Relay
Output Boards are referenced to neutral (Wire 2). For
example, the fan output on TB1-6 is a single 120VAC
output. 0-12VDC outputs from the Chiller Control
Board are referenced to 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. Refer
to the wiring diagrams whenever there is a requirement
for tracing out these signals.
