26 Q9 Plus Bypass ASD/Bypass Box Installation and Operation Manual
I/O Monitoring and Control
The Q9 Plus Bypass ASD/Q9 Plus Bypass Box can be controlled by several input types and
combinations thereof, as well as operate within a wide range of voltage levels. This section discusses
the control methods and supported I/O functions.
The Terminal Board (shown on pg. 30 ) of the Q9 Plus Bypass ASD/Q9 Plus Bypass Box supports
discrete and analog I/O functions. Table 1 lists the names, descriptions, and the default settings (if
programmable) of the input and output terminals of the Terminal Board . See the section I/O Terminal
Descriptions on pg. 27 for more information on the listed terminals.
Table 1. Terminal Board Terminal Names and Functions.
Terminal
Name
Circuit Type
Function
(Default setting if programmable)
ST
Discrete Input
Connect to CC to
activate (Sink
mode).
Standby — Multifunctional programmable discrete input. Activation required for normal ASD
operation.
RES
Reset — Multifunctional programmable discrete input. Activation resets ASD when Faulted
— ignored when not Faulted.
F Forward — Multifunctional programmable discrete input.
R
Reverse — Multifunctional programmable discrete input.
S1 Fire Speed — Multifunctional programmable discrete input.
S2
Preset Speed 2 — Multifunctional programmable discrete input.
S3 Damper Feedback — Multifunctional programmable discrete input.
S4
Emergency Off — Multifunctional programmable discrete input.
CIA/CIB Interlock
Customer Interlock — The CIA -to- CIB interlock connection is accomplished via a jumper, a
relay, etc., and is required for normal system operation.
DRA/DRB Damper Input
Damper Response — The DRA -to- DRB connection is accomplished via limit switches at the
opened damper and is required for normal system operation.
DSA/DSB
(OUT1)
Switched
Output
Damper Command — Multifunctional programmable dry contact that is used to open/close
the 120 VAC damper motor power circuit when the motor is ASD-driven.
OUT2 A/B
Acc/Dec Complete — Multifunctional programmable output that changes state when the
programmed acceleration or deceleration ramp is reached.
FLC Fault relay (common).
FLB
Fault relay (N.C.).
FLA Fault relay (N.O.).
RR
Analog Input
Frequency Mode 1 — Multifunction programmable analog input (0.0 to 10 volt input — 0 Hz
to Maximum Frequency).
RX
Unassigned — Multifunctional programmable analog input (-10 to +10 VDC input).
I
Frequency Mode 2 (default setting) — Multifunctional programmable analog current input (4
[0] to 20 mADC input — 0 Hz to Maximum Frequency).
V Unassigned — Multifunctional programmable analog voltage input (0 to 10 VDC input).
AM
Analog Output
Output Current — Multifunctional programmable voltage output that is proportional to the
output current of the ASD or to the magnitude of the function assigned to this terminal.
FM
Output Frequency — Multifunctional programmable Current or Voltage output that is
proportional to the output frequency of the ASD or to the magnitude of the function assigned to
this terminal. Select
Current or Voltage at F681 .
P24
DC Output
24 VDC (200 mA max.) output.
PP
10.0 VDC (10 mA max.) voltage source for the external potentiometer.
FP
Pulsed Output
Output Frequency — Multifunctional programmable output pulse train of a frequency based
on the output frequency of the ASD or of the magnitude of the function assigned to this
terminal.
CC
— Return for all input and output terminals ( DO NOT connect to Earth Gnd ).
