NEW TECHNOLOGIC® 5500 CONTROLLER
LATEST ADDITION TO BELL & GOSSETT’S POWERSAVE® LINE

Morton Grove, IL - March 15 2002

A new combination multiple-pump and multiple-zone pump controller designed to provide optimum performance, reliability and energy savings has been added to Bell & Gossett’s popular Powersav® line of Technologic® pump controllers.

The new Technologic 5500 Series has the capability to receive sensor inputs, stage pumps, control AFD speed and monitor motor performance in order to meet system demands. Furthermore, it combines PID functions, setpoint modification, and system and component status into a single, central, user-friendly unit.

The controller is designed to safeguard against damaging hydraulic conditions including: motor overload, pump flow surges, hunting and end of curve (flow sensor required). It is also capable of staging and destaging pumps based on an Efficiency Optimization Program to provide the lowest kW draw.
Other standard features of the Technologic 5500 Series include:

· Operator Interface Diagnostics
· Multi-fault Memory and Recall
· Pump Elapsed Time (Individual)
· Communication to BAS
· Manual and Automatic Alternation
· Automatic Start of Lag Pump upon Lead Pump Failure (in Variable or Constant Speed Mode)
· Data Logging of Alarms, Pump Run Time & Signal Data
· Fused 24-Volt Power Supply
· NEMA 1 Enclosure

A special memory storage function prevents accidental loss of data due to voltage surge or spike. In the event of a complete power outage, all field-preset values remain stored and can be recalled.

Offering the same proven “Common Logic” set-up and operating format as other controllers in the family of Technologic Controllers (Technologic 350 and 500), the 5500 provides the same clear, detailed messages, status indications and diagnostics in plain English on a 4 line, 20 character illuminated LCD display for easy viewing in all lighting conditions.
