CONFIGURATION PARAMETERS
Analog/Digital Input/Output Options and Functional
Description
This section includes detailed configuration informa-
tion for VAV air handling unit control.:
• Configuration Parameters
• Setpoint Parameters
• Analog Inputs
• Digital Inputs
• Analog Outputs
• Digital Outputs
• VAV Configuration Requirements
The tables list the available inputs and outputs, their
control numbers, the label as it appears in the S7600A
Keyboard Display Module, and a functional description of
the point as it is used in the control algorithm.
Configuration parameters are listed with their descrip-
tions and recommended values. Input and output points are
assigned to specific W7600 and W7601 terminals by using
the ZM7601 or ZM7603 software. However, a W7600
control system provides only the number of physical ana-
log and digital input and output channels available for the
particular W7600 model applied. For example, the W7600A
provides four analog outputs and eight digital outputs.
Therefore, if more than four analog or eight physical digital
outputs are required, a W7601 Expansion Module must be
added to the system.
Also, inputs and outputs defined in these tables are
specific to the PM7600B, which means that inputs and
outputs defined for the PM7600B may be wired
only
to the
W7600 containing the PM7600B.
NOTE: Alarm priority level 99 is the lowest prior-
ity and will not generate an alarm in the control-
ler or on the network for remote and physical
analog inputs. This eliminates multiple alarms
on the network when datasharing from a source
point. All other alarms with priority 99 will
generate alarms in the controller and on the
network.
