I/O Terminal Descriptions
Note:
The programmable terminal assignments may be accessed and changed from their
default settings as described in the
Q9 Plus ASD Installation & Operation Manual
.
ST
— The default setting for this terminal is the
Standby
mode controller. As the default setting, this
terminal must be activated for normal system operation. The
ST
terminal is activated by connecting
CC
to this terminal (Sink mode). When deactivated,
OFF
is displayed at the
Frequency
Command
screen.
This input terminal may be programmed to any of the discrete terminal functions that are listed in the
Q9 Plus ASD Installation & Operation Manual
.
RES
— The default setting for this terminal is
Reset
. The
RES
terminal is activated by connecting
CC
to this terminal (Sink mode). A momentary connection to
CC
resets the ASD and any fault indications
from the display.
Reset
is effective when faulted only. This input terminal may be programmed to any
of the discrete terminal functions that are listed in the
Q9 Plus ASD Installation & Operation Manual
.
F
— The default setting for this terminal is
Forward Run
. The
Forward Run
terminal is activated by
connecting
CC
to this terminal (Sink mode).
Forward Run
runs the motor in the
Forward
direction for
the duration of the activation. This input terminal may be programmed to any of the discrete terminal
functions that are listed in the
Q9 Plus ASD Installation & Operation Manual
.
R
— The default setting for this terminal is
Reverse Run
. The
Reverse Run
terminal is activated by
connecting
CC
to this terminal (Sink mode).
Reverse Run
runs the motor in the
Forward
direction for
the duration of the activation. This input terminal may be programmed to any of the discrete terminal
functions that are listed in the
Q9 Plus ASD Installation & Operation Manual
.
S1
— The default setting for this terminal is
Fire Speed
. The
Fire Speed
terminal is activated by
connecting
CC
to this terminal (Sink mode). The function of this input as
Fire Speed
is to run the motor
at the
Preset Speed 1
setting for the duration of the activation and is typically initiated by a fire/smoke
sensing device. This input terminal may be programmed to any of the discrete terminal functions that
are listed in the
Q9 Plus ASD Installation & Operation Manual
.
S2
— The default setting for this terminal is
Preset Speed 2
. The
S2
terminal is activated by
connecting
CC
to this terminal (Sink mode). The function of this input as
Preset Speed 2
is to run the
motor at the
Preset Speed 2
setting for the duration of the activation. This input terminal may be
programmed to any of the discrete terminal functions that are listed in the
Q9 Plus ASD Installation &
Operation Manual
.
S3
— The default setting for this terminal is
Damper Feedback
. The
Damper Feedback
terminal is
activated by connecting
CC
to this terminal (Sink mode). The function of this input as
Damper
Feedback
is to complete the requirements for normal system operation as described in the section titled
Theory of Operation
on
. This input terminal may be programmed to any of the discrete terminal
functions that are listed in the
Q9 Plus ASD Installation & Operation Manual
.
S4
— The default setting for this terminal is
Emergency Off
(normally closed). The
Emergency Off
terminal is activated by opening the connection to
CC
(Sink mode). The function of this input as
Emergency Off
is to remove power from the output of the ASD and may apply a supplemental braking
system using the method selected at the
Emg Off Mode
selection parameter (
F603
). This input terminal
may be programmed to any of the functions that are listed in the
Q9 Plus ASD Installation &
Operation Manual
.
CIA/CIB
— These terminals are used to complete the
Customer Interlock
function. The
CIA
-to-
CIB
connection is a requirement for normal
Q9 Plus Bypass ASD/Q9 Plus Bypass Box
operation. These
terminals may be connected using a jumper or are used to Enable/Disable the system as a function of a
user-selected event or condition that will open or close this circuit. See the section titled
Theory of
Operation
