Manual Override
Manual Override can be used to disable the PumpSmart control algorithm and operate the pump at a preset
speed. PumpSmart may be placed into manual override through DI-2 (e.g. Hand-Off-Auto switch or separate
Manual Override switch) or through selection via keypad entry. When in Manual Override the keypad will display
the message “WARNING MANUAL OVERRIDE.”
When parameter 12.01 START/STOP is set to 2 WIRE/HOA and DI-2 is closed, PumpSmart will disable the control
and protection algorithms and operate at the speed set in parameter 12.07 MANUAL OVERRIDE RPM.
!
!! WARNING !!
Placing the drive in Manual Override disables ALL Pump Protection functionality except E-
stop/permissive and Keypad failure. Ensure that operating conditions are satisfactory for safe and
reliable pump operation before enabling the manual override function.
NOTE: When using a Digital Input to enable the manual override function, PumpSmart looks solely at the state of
DI-2 and DI1L. The state of DI-1 does not effect the enabling of the manual override function.

Minimum Speed Options
When the PumpSmart PS200 reaches the minimum speed that is set in parameter 14.02 MINIMUM SPEED, it can
be programmed to stay at that minimum speed indefinitely, or to shut-down. This reaction applies to conditions
where PumpSmart is trying to regulate to a setpoint, when it faults due to a secondary protect condition, or there
is little or no process demand.
If the parameter 14.05 CONFIG SPEED MIN is set to SPD=MINSPD, the drive will stay at minimum speed until the
process demand increases, it is shutdown manually, or a fault occurs forcing it to shutdown. If it is operating at
minimum speed due to a Secondary Protect fault, it will stay at minimum speed until the fault is reset.
If a Pump Protect condition exists and CONFIG SPEED MIN is set to SPD=MINSPD, PumpSmart will try to reset the
fault while at minimum speed if parameter 12.02 AUTO RESTART is set to “ON” and parameter 25.04 ERROR
RESET is set for the desired number of attempts. If the fault has not cleared after the selected number of resets
has been attempted, the pump will be shut down. If parameter 25.04 ERROR RESET = 0, the pump will be shut
down upon a Pump Protect fault.
If parameter 14.05 CONFIG SPD MIN is set to SPD=0, the drive will stop the pump for Pump Protect and
Secondary Protect faults. The reaction to stop the pump when at minimum speed can be delayed for up to 1800
seconds by programming parameter 14.06 STP DELAY MIN SPD.
