DRA/DRB — These terminals are used to complete the Damper Response function. The DRA-to-
DRB connection is a requirement for normal Q9 Plus Bypass ASD/Q9 Plus Bypass Box operation.
These terminals may be connected using a jumper or used to Enable/Disable the system as a function of
an event or condition that will open or close this circuit. See the section titled Theory of Operation on
pg. 13
for further information on these terminals.
DSA/DSB (OUT1) — The default function assigned to this output contact is Damper Command. As
such, it is used to switch an externally-supplied 120 VAC to the damper motor. This output terminal
may be programmed to provide an indication (open or closed) that a user-selected function has occurred
or is active. Once the ASD receives a run command, any terminal that is set to the Damper Command
function changes state. This function may be used to signal external equipment (e.g., switch power to
the damper motor). The OUT1 contact is rated at 2 A/120 VAC and 2 A/30 VDC. See the section titled
Theory of Operation on
pg. 13
and the Q9 Plus ASD Installation & Operation Manual for further
information on this terminal.
OUT2 A/B — The default function assigned to this output contact is ACC/DEC Complete. This
output terminal may be programmed to provide an indication (open or closed) that a user-selected
function has occurred or is active. This function may be used to signal external equipment (e.g., activate
the brake). The OUT2 contact is rated at 2A/250 VAC. See the Q9 Plus ASD Installation & Operation
Manual for further information on this terminal.
FLC — FLC is the common leg of a single-pole double-throw form C relay. The FL relay is the Fault
Relay by default but may be programmed to any of the selections listed in the Q9 Plus ASD
Installation & Operation Manual.
FLB — The normally-closed leg of the FL relay.
FLA — The normally-open leg of the FL relay.
Note:
The FLA, FLB, and FLC contacts are rated at 2A/120 VAC and 2A/30 VDC.
RR — The default function assigned to this terminal is the Frequency Mode 1 setting. The RR
terminal accepts a 0 – 10 VDC input signal that is used to control the function assigned to this terminal.
This input terminal may be programmed to control the speed or torque of the motor via an amplitude
setting or regulate by setting a limit. The gain and bias of this terminal may be adjusted for application-
specific suitability. See the Q9 Plus ASD Installation & Operation Manual for further information on
this terminal.
RX — The RX terminal accepts a ±10 VDC analog input signal and controls the function assigned to
this terminal. This input terminal may be programmed to control the speed, torque, or direction of the
motor. It may also be used to regulate (limit) the speed or torque of the motor. The gain and bias of this
terminal may be adjusted for application-specific suitability. See the Q9 Plus ASD Installation &
Operation Manual for further information on this terminal.
I — The default function assigned to this terminal is to carry out the Frequency Mode 2 setting. The
function of the I terminal is to receive a 4 – 20 mA input signal that controls a 0 – 80 Hz output (or the
user-selected function). This input terminal may be programmed to control the speed or torque of the
motor and may not be used when using the V input terminal. It may also be used to regulate (limit) the
speed or torque of the motor. The gain and bias of this terminal may be adjusted for application-specific
suitability. See the Q9 Plus ASD Installation & Operation Manual for further information on this
terminal.
V — The function of the V terminal is to receive a 0 – 10 VDC analog input signal that is used to
control a user-selected function. This input terminal may be programmed to control the speed or torque
of the motor and may not be used when using the I input terminal. It may also be used to regulate (limit)
the speed or torque of the motor. The gain and bias of this terminal may be adjusted for application-
specific suitability. See the Q9 Plus ASD Installation & Operation Manual for further information on
this terminal.
