E-E-FlexFlex™™ Design ConceptsDesign Concepts


E-E-FlexFlex™™ Design ConceptsDesign Concepts• ALTIVAR® 61 AC Variable Torque Drive

– Large, easy to use Graphic Display on door mounted keypad

– Quick start-up menu with macro-configuration for HVAC Pumps and Fans

– Network connectivity for building automation networks

• Thermal Management System– 1-50 HP Type 1 - No internal fans

– 1-7.5 HP Type 1 - No heat sink fan

• Front accessible heat sink fans– Eliminates rear access requirements

– Ease of repair / service


E-E-FlexFlex™™ Design ConceptsDesign Concepts

• Enclosure Designs– Type 1 rated construction

• Designed for indoor use -- enclosure protects components from physical contact with operating personnel

• Top and bottom conduit entry with knockouts

– Type 12K rated construction• Designed for indoor use environments containing dust, dirt, fibers, lint, and non-

corrosive dripping liquids

• Top and bottom conduit entry with knockouts

– Type 3R rated construction• Designed for outdoor use -- protection from rain, sleet, and ice formation

• Ideal for ground level or rooftop applications

• Bottom conduit entry with knockouts


E-FlexE-FlexTMTM Design Concepts Design Concepts

Seismic Qualification Option for Ground and Roof Level Applications

• Meets 2003 IBC and ASCE 7 standards for seismic qualification in accordance with ICC ES AC156 testing protocol with an Importance Factor of 1.5 for 42 states.

• Some exceptions include California, Alaska, Hawaii, Kentucky, Tennesse, and Arkansas which are site specific.

• When mounted in accordance with published guidelines, the E-FlexTM enclosure is designed and constructed to withstand violent vibration loads.

• E-FlexTM Drives have been subjected to actual shaker table tests and not just theoretical anchorage and bolt-hole calculations for seismic ratings.


E-E-FlexFlex™™ - - Type 3RType 3R

• Complete Type 3R Product Lineup

– 1 to 100 HP @ 460 VAC

– 1 to 50 HP @ 208/230 VAC

– Compact Design

• 4 physical frame sizes

• Same mounting size as Type 1 and 12K Indoor Enclosures



• Lower Installed Cost– Shorter conduit runs to motor

• Reduces motor lead lengths by mounting drive closer to motor

• Reduces need for motor protection filter

– Ideal for retrofit installations• Relieves overcrowding in mechanical

rooms

• Reduces heat load in mechanical rooms by mounting outdoors

10



• Thermal Management System– +14 to 122F (-10 to 50C) ambient

temperature rating • Thermostatically controlled space heater

• No air conditioner or special heat exchanger required

– Vermin filters on inlet and outlet ventilation openings

– “It can handle the weather”

11


E-E-FlexFlex™™ - - Power OptionsPower Options

• Circuit Breaker Disconnect (standard)

– UL 508C listed

• Short circuit protection for both drive and bypass

• Eliminates expensive and non-stock, current limiting type fuses

– Coordination with NEMA ICS 7.1

• Worse case short circuit protection

• Enhanced personnel safety exceeds minimum UL requirements

12



• Emergency Full Speed Bypass Option

– Mechanical & Electrical interlocked-improved reliability

• Prevents accidental back feeding of line voltage to drive

– Sequenced to provide motor isolation in drive ready state

– Bypass and Isolation contactors fully rated

– Class 20 overload in bypass mode• Provides longer acceleration

time for high inertia fans

13



• Input Line Contactor– Automatically removes power from

drive controller when in ready state• Competition offers only manual

isolation

– Used with bypass to meet 3-contactor bypass requirements

– Not available with Type 3R• Necessary to maintain input

power to prevent condensation build up

• Power requirement for space heaters

14



• Enclosed Line Reactor– 3% reactor is standard

– 5% line reactor is optional

– Reduces input line RMS currents to match output current

– Provides additional transient protection from over voltages, power factor capacitor switching

15


E-E-FlexFlex™ ™ - - Control OptionsControl Options

• Control Functions and Options– HAND-OFF-AUTOMATIC Selector Switch

• Provides remote operation of drive and bypass

• Auto Restart capability with 2-wire control

– 3 to 15 PSI Pressure Transducer Pneumatic Interface• For retrofit applications using pneumatically controlled devices

– TEST-NORMAL Selector Switch (available only with Bypass package)• Allows the user to test drive operation without turning the motor

• Allows the user to test drive operation while running in bypass

– Pilot Light Options• POWER ON • AUTO MODE

• DRIVE RUN • BYPASS RUN

• FAULT

16


E-E-FlexFlex™™ - - Control OptionsControl Options

• Control Functions and Options– Smoke Purge Relay

• Provides interface to building fire protection system

• Overrides operator controls and runs motor at full speed on bypass for smoke evacuation

• Operates drive at high speed setting when bypass is not supplied

– Freeze / Fire Stat Interlocks• User provided contact (normally closed) from HVAC system

• Prevents drive or bypass operation in the event of excessive heating or cooling by the HVAC system

– Auxiliary Contacts• Form C relays for drive run and fault indication

– Building Automation Network Communication Capability• LonWorks, Modbus, BACnet, Metasys N2, Apogee P1 and Ethernet
