Q9 Plus Bypass ASD/Bypass Box Installation and Operation Manual

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

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

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

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

relay.

FLA

— The normally-open leg of the

relay.

Note:

The

FLA

FLB

and

FLC

contacts are rated at 2A/120 VAC and 2A/30 VDC.

— The default function assigned to this terminal is the

Frequency Mode 1

setting. The

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.

— The

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.

— The default function assigned to this terminal is to carry out the

Frequency Mode 2

setting. The

function of the

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

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.

— The function of the

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

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.
