established, the controller will attempt to provide a polymer flow rate that will provide the user a
desired “solution” concentration. B-series controllers, upon the user entering primary and
secondary water flows, will automatically adjust the pump speed to provide the current and
future user requested solution concentration. If water flows change concentration errors will
occur.
B++ Series
B++ Series controllers come equipped with both primary and secondary water flow rate
monitoring. Having flow rate meters allows the system to automatically monitor and display
both water flows. This monitoring of water flow automatically allows adjustment of the polymer
flow rate. Water flow disturbances and flow deviations are sensed and concentration is
continuously corrected by pump speed/flow adjustment, providing consistent real-time
concentration control.
3.2 Polyfeeder B-Series Remote Controller General Description
The Polyfeeder B controller provides system level control, monitoring, system status indication,
and programmability of the polymer make-down system. Control mechanisms include water
supply activation, mixing chamber motor activation, and polymer pump speed/flow pacing via an
internal PLC. The controller provides a control panel user interface allowing three modes of
operation via a three way switch. These modes are: local, off, and remote. See section 6.2.1 for
detail descriptions. The controller also provides monitoring functions via an LCD display and
lamp indicators. Major system elements such as water valve status (open or closed), mixing
chamber motor state (on/off) and polymer pump state (on/off) are indicated by red indicators.
System alarming is indicated via yellow indicator and alarm reset is provided with a red push
button. All programmability is performed via the UP, DOWN, and ENTER keys and the LCD
text display. System local starting and stopping is provided using the green start stop.
4. Equipment Inspection
Check all equipment for completeness against the order and for any evidence of shipping damage.
Shortages or damage must be reported immediately to the carrier and your authorized representative or
distributor.
5. Storage
5.1 Short Term
Storage of your PolyFeeder
®
system for up to 12 months is considered short-term. The recommended
short-term storage procedures are:
a) Flush the system with an oil to remove all neat polymer from the system. Do not introduce
water into the neat polymer piping as it will cause clogging once neat polymer is reintroduced.
b) Remove all water from piping to avoid bursting of pipes in situations where the ambient
temperature could drop to levels below which water freezes.
c) Store the system indoors at room temperature in a dry environment.
