20 Q9 ASD Installation and Operation Manual
Terminal Descriptions
Note: The programmable terminal assignments may be accessed and changed from their
default settings as mapped on pg. 41 or via the Direct Access method: Program
Direct Access Applicable Parameter Number. See the section titled Program
Mode Menu Navigation on pg. 41 for the applicable Direct Access parameter
numbers.
For further information on terminal assignments and default setting changes, see the
sections titled Default Setting Changes on pg. 57 and Input Terminals on pg. 44.
Note: See the section titled Cable/Terminal Specifications on pg. 213 for the Q9 ASD
conductor and terminal electrical specifications.
Note: Programmable terminals will not retain their settings indefinitely in the event of a
power loss. Connect an external +24 VDC supply to the SU+ terminal to retain the
programmable settings in the event of Control Power loss (See Figure 20 on pg. 24).
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 on the Frequency Command
screen. This input terminal may be programmed to any of the functions listed in Table 4 on pg. 186
(See F113).
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 functions listed in Table 4 on pg. 186 (See F114).
F — The default setting for this terminal is Forward run command. The F terminal is activated by
connecting CC to this terminal (Sink mode). This input terminal may be programmed to any of the
functions listed in Table 4 on pg. 186 (See F111).
R — The default setting for this terminal is Reverse run command. The R terminal is activated by
connecting CC to this terminal (Sink mode). This input terminal may be programmed to any of the
functions listed in Table 4 on pg. 186 (See F112).
S1 — The default setting for this terminal is Fire Speed. The function of this input as Fire Speed is to
run the motor at the Preset Speed #1 setting upon activation. This terminal may be activated by
connecting CC to this terminal (Sink mode) and may be initiated by a fire alarm signal or fire/smoke
sensing device. This input terminal may be programmed to any of the functions listed in Table 4 on
pg. 186 (See F115).
S2 — The default setting for this terminal is Preset Speed 2. The function of this input as
Preset Speed 2 is to run the motor at the Preset Speed 2 setting upon activation. The terminal may be
activated by connecting CC to this terminal (Sink mode). This input terminal may be programmed to
any of the functions listed in Table 4 on pg. 186 (See F116).
S3 — The default setting for this terminal is Damper Feedback. The function of this input as Damper
Feedback is to complete the requirements for normal system operation as described in Table 4 on
pg. 186. The S3 terminal is activated by connecting CC to this terminal (Sink mode). This input
terminal may be programmed to any of the functions listed in Table 4 on pg. 186 (See F117).
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 (See F603). This input
terminal may be programmed to any of the functions listed in Table 4 on pg. 186 (See F118).
