System Start
Controller door 3 position selector switch. Determines if controller is
enabled locally (ON) or is enabled remotely (REMOTE) by a dry contact to
start or stop control action. The middle switch position OFF disables the
controller and initiates a flush cycle if this switch is left in this position >2
seconds after first operating in either ON or REMOTE.
Polymer Pump
Controller door 2 position selector switch. Determines the setpoint for pump
control action which can either be pump speed or % concentration. If set to
the LOCAL position the setpoint is based on the keypad entry and if set to
REMOTE then the setpoint input is from a remote 4-20 mA signal.
Inline / Batch
The user must choose the mode of operation from a keypad menu selection.
Default is Batch mode and the setpoint is % concentration. The polymer
pump is automatically adjusted to maintain the desired % concentration
regardless of fluctuations of the dilution water flow. Inline mode requires the
user to calculate the percent concentration desired and then manually adjust
the pump speed based upon the measured dilution water flow rate.
Emulsion / Mannich
The user must choose the type of polymer being used by the ProMix feeder.
If emulsion then a maximum of 1.0% concentration is permitted in the mixing
chamber. If Mannich is selected then the maximum is 10.0% concentration.
Batch mode will automatically limit the polymer feed to maintain these
concentrations.
