Sel. No.
NO NC
Fastest Deceleration Command — Using dynamic braking (if enabled and supported), stops the motor at the
122 123
fastest rate allowed by the load.
Preliminary Excitation — Applies an excitation current to the motor (holds shaft stationary) for the duration of the
124 125
activation.
136 137 Start-Stop HOA — Activates the Auto Start-Stop operating mode in accordance with the settings of F385.
Low Suction/No Flow Protection — Will not allow the ASD to start if activated, or terminates the ASD output
138 139
upon activation (if running) in the event of the loss of feed water or a closed output valve at the pump output.
Sealing Water — Once an adequate water supply is detected at the pump seal via a reed switch, activation enables

140 141
the ASD for normal operations.
Virtual Linear Pump Enable/Disable Switch — Activation enables the Virtual Linear Pump function for
142 143
normal operation. The Virtual Linear Pump function is disabled when the terminal is not active.
144 145 TBA ON Float — Activation runs the ASD at the setting of F390.
TBA OFF Float — Activation has a dual function:
146 147
1) Changes the operating mode from Process Hold to Direct.
2) Turns off the ASD.
148 149 TBA Trigger Float — Activation changes the operating mode from Process Hold to Direct.
TBA Warning Float — This input is typically connected to a float switch that, when activated, annunciates that the
fluid level is now critical. The discrete output terminals OUT1 and/or OUT2 may be associated with the activation (set
150 151
OUT1/OUT2 to TBA Alarm Float to activate an auxiliary system — i.e., aux pump, relief valve, audible/visual
alarm, etc.).
TBA Hand-Off-Auto — Activation enables Time-Based Alternation operation. Operates in conjunction with the
152 153
setting of F417.
154 155 V/Hz Rate Switching —
156 157 Manual Boost Switching —
Note: The Selection Number is used when setting the terminal via communications.
NO/NC = Normally Open/Normally Closed.
