(Even in bypass mode, the new ABB E-Clipse Bypass talks always with Architecture Automation Systems)
NEW BERLIN, Wis., January 22, 2008…ABB today appear the aing bearing of bypass technology in motors drives, which are acclimated throughout the HVAC (Heating Ventilation & Air Conditioning) industry. Calling it “a bypass with brains,” the new ABB E-Clipse Bypass is the aing archetype about-face in cyberbanking bypass design– ideal for bank ascent and/or applicable into air-handling units and pumping bales on all types of OEM accessories acclimated in the HVAC industry.
“Bypass technology is acclimated in affiliation with about two-thirds of all drive installations for motor ascendancy in HVAC applications,” addendum Jeff Miller, carnality president, bartering sales, ABB Low Voltage Drives. “Bypass technology allows architecture managers to accumulate motors in constant-speed operation, if and aback drives charge to be maintained, or accountability for some reason. Such operation can be critical, decidedly for ensuring intake- and exhaust-air admirers accomplish during all conditions, including fire,” he said.
Ideal Aback The new ABB E-Clipse Bypass is the aboriginal architecture to communicate, like ABB’s drives, anon with Architecture Automation Systems. “That keeps ability managers in absolute ascendancy of all their HVAC requirements, alike in altitude area electrical challenges may cruise out the drives. It’s an ideal aback technology and accessory that is a cast new development for this market,” Miller said.
This accession decidedly extends ABB’s aboriginal E-bypass design, alien in 1998. Worldwide, there are added than 100,000 E-bypass installations in operation. Further abstraction of this bazaar – its applications and requirements – resulted in the new artefact line, which is actuality alien to the bazaar at the all-embracing AHR (Air-Conditioning, Heating, Refrigerating) Exposition in New York.
ABB E-Clipse Bypass – Technology to the Aing Akin The ABB E-Clipse Bypass takes the abounding agenda microprocessor-based controls pioneered in the aboriginal E-bypass “to the aing akin – a seismic advance,” according to Mike Olson, manager, HVAC applications. “The technology incorporates new capabilities that acknowledgment the needs of the alteration and evolving chump and bazaar requirements.”
Available in a UL Type 1, UL Type 12 or NEMA 3R asylum – and chip with ABB’s ACH DriveIT Low Voltage 550 adjustable-speed AC drives — the two-contactor bypass appearance both a account about-face that disconnects the drive for service, and a capital abstract about-face or ambit breaker. The bifold about-face eliminates downtime, aback the motor/load never needs to go offline; this aback affection – ensuring ceaseless operation – continues to accomplish bypass drives the adopted best amid added than bisected of all bartering applications, according to ABB.
Common Protocols are Accepted Feature; Ascendancy Through All Conditions! The ABB E-Clipse Bypass includes the added accepted HVAC protocols as accepted features. Included in every bypass alien are Modbus RTU, Johnson Controls N2, Siemens FLN, and BACnet communications protocols. Added protocols, such as LonWorks, Profibus-DP, Ethernet/IP, Modbus TCP, DeviceNet and CANopen, are accessible as constituent advantage cards.
This next-gen bypass technology additionally extends the consecutive communications for VFDs that ABB pioneered for the HVAC industry in 1994 – and resulted in added than 150,000 units (in the U.S., alone) affiliated to architecture automations systems, appliance these assorted communications protocols. “And now the ABB E-Clipse Bypass includes consecutive communications in the bypass mode” acclaimed Olson, “which agency that, for the aboriginal time, activity to bypass does not beggarly accident ascendancy but, rather, befitting ascendancy through all conditions!”
“In all antecedent designs, switching to bypass approach meant the VFD displayed as a bootless point on the architecture automation arrangement network,” acclaimed Olson. However, via the ABB E-Clipse Bypass, consecutive communications to the bypass ambassador now ensures there is no accident of advice or control, and no bootless point on the BAS network. “The VFD may alike be removed (and beatific aback to the branch for repair, for example) from the arrangement with no accident of communications,” said Olson. And the BAS arrangement still can alpha and stop the appliance and adviser amps, volts, and application hours – in bypass mode.
Multiple Abstracts Credibility from Bypass to Adept Ambassador Over 45 abandoned credibility of abstracts are announced amid the bypass and the BAS arrangement adept controller. For example, the abettor can adviser all safeties, damper end-switch proofs, and any added agenda inputs to the system. In addition, the abettor can alpha and stop the bypass over consecutive communications or force the arrangement into override mode.
Proof-of-flow, over-temperature conditions, or added arrangement warnings may additionally be displayed on the BAS adept controller. Finally, all faults can be displayed at the adept ambassador forth with alien arrangement displace adequacy via communications.
In 1997, ABB pioneered VFD consecutive communications pass-through I/O. Pass-through I/O enables users to adviser all agenda inputs on the capricious abundance drive, and ascendancy all broadcast outputs and analog outputs on the capricious abundance drive. The canyon through I/O now is broadly adopted by the added accelerating temperature-control contractors as a adjustment of abbreviation arrangement costs, according to Olson.
Why is this notable? For example, a BAS integrator now can use the VFD broadcast outputs to alpha a lag pump drive, accessible an a damper, or ascendancy any abetting accessory that appropriate a maintain-contact cease for operation. In addition, all agenda inputs such as damper-receipt affidavit contacts, safeties, or supply-fan run interlocks to the acknowledgment fan can be monitored over the architecture automation arrangement through the VFDs I/O.
However, appliance the VFDs I/O for ascendancy of the arrangement inherently meant that if the VFD was in a non-operational state, and any accessory accessories that were actuality controlled through the VFD’s I/O were additionally non-operational. “The ABB E-Clipse bypass addresses these concerns,” said Olson. “With the ABB E-Clipse bypass, I/O charcoal accessible to the BAS arrangement alike with the VFD removed. The BAS arrangement integrator/end user now has complete aplomb that alike if the drive were to fail, any accessory accessories actuality monitored and/or controlled appliance the arrangement I/O accessible is still anatomic – alike in the bypass mode.”
Easy-read Affectation The new ABB E-Clipse Bypass includes a dedicated, apparent English affectation for avant-garde annunciation. The affectation is able of advertence which (of up to four) altered assurance inputs accept opened. The user can accept from a predefined account of eight altered assurance names for affectation on the keypad and affectation on the BAS arrangement adept controller. For example, one agenda ascribe may be assigned the name “FireStat.” Another agenda ascribe may be programmed to affectation “FreezeStat.” In addition, the keypad will affectation (in English) all bypass diagnostic, admonishing and accountability indications.
Previous Appearance Chip into New Architecture All key appearance in ABB’s aboriginal E-Bypass accept been chip into the new design, according to Peter Walter, artefact business administrator for ABB HVAC drives. These appearance include: run-permissive chip (damper ascendancy with end-switch proof); drive absolute fast-acting fuses; proof-of-flow (broken belt) adumbration and action; motor distinct appearance protection; no contactor babble affirmed through a voltage altruism ambit of 30%, -35% of nominal voltage; two Fireman’s overrides; keypad ascendancy with one-line diagram and cachet adumbration LEDs; programmable Class 20 or Class 30 cyberbanking motor afflict protection; and selectable chiral or automated alteration from drive to bypass.
