The Asco Series 7000 service entrance power transfer switch combines manual power switching with a disconnect and overcurrent protective device on the utility source. This Asco 7000SE manual (non-automatic) transfer switch is ideal for mission critical applications with single phase loads up to 1000A.

TRANSFER SWITCH FEATURES

  • Electrically operated with manual control switches mounted locally or at remote locations.
  • Microprocessor based controller prevents inadvertent operation under low voltage conditions and allows for addition of optional accessories.
  • Low control circuit operating currents allow for long line runs between remotely mounted manual control switches and the transfer switch.
  • Source acceptability lights inform operator if sources are available to accept load.
  • Standard in-phase monitor can be activated for transferring motor loads.
  • Reliable and field-proven solenoid operating mechanism for high speed transfer of loads.
  • Conventional Open Transition (break-before-make) two-position transfer configuration. (Closed and Delayed Transition configurations available - see below.)
  • Optional Bypass Isolation models available - see below.
  • Programmable microprocessor controller with keypad and LCD display.
  • Industrial grade user interface with integrated controls and indicating lights.
  • High withstand and close-on ratings including short time withstand current rating for optimum flexibility in circuit breaker coordination.
  • Front replaceable main and arcing contacts.
  • Standard ground conductor connections.
  • Four auxiliary contacts, two contacts closed when switch is in normal position and two contacts closed when switch is in emergency position.
  • Centrally located terminal block for all customer control connections.
  • Local/remote communications capability for interfacing with ASCO PowerQuest® communication products.
  • Options of solid, switched, or overlapping neutral conductor - see below.
  • UL 1008 Listed and CSA Certified.
  • NEMA 1 indoor enclosure standard (with numerous other options - see below).

SERVICE ENTRANCE FEATURES

  • Meets all National Electric Code requirements for installation at a facility’s main utility service entrance.
  • Generally are installed at facilities that have a single utility feed and a single emergency power source.
  • Ground fault trip protection provided.
  • Circuit breaker offers utility disconnect and overcurrent protection.
  • Standard Ampere Interrupting Capacity (AIC) Rating of 65kA.
  • Disconnect link on Neutral.
  • Disconnect link on Ground.
  • Ground and Neutral Bus - all silver-plated copper.
  • Solderless screw type terminals for External Power Connections.
  • Internet enabled monitoring and control.
  • UL 891 Listed.

CONTROL FEATURES

Asco Series 7000 Microprocessor Controller

  • asco4000-controller-in.jpgAdvanced digital microprocessor.
  • Voltage, frequency, control, timing, and diagnostic functions.
  • Microprocessor logic board is separated and isolated from the power board to improve electrical noise immunity performance and assure compliance with rigorous transient suppression standards.
  • Allows the user to easily access detailed information on: system, power source parameters, voltage, frequency and time delay settings, optional feature settings, historical event log, and system diagnostics.
  • A four line, 20 character LCD has a backlit display which enables easy viewing under all conditions (see Asco 7000 Brochure below for screen shots).
  • All screens can be navigated using only six buttons.
  • Touch pad programming of features and settings without the need for meters or variable power supplies.
  • On-board diagnostics provide control panel and ATS status information to analyze system performance.
  • Displays and counts down active timing functions.
  • Selectable multi-language display (English, German, Portuguese, Spanish, or French).
  • Password protection to prevent unauthorized tampering of settings.
  • For more detailed information, see 7000 Series Microprocessor Controller.

Asco Series 7000 User Interface

  • Manual transfer control switch for transferring load from normal to emergency, and back again.
  • Switch position indicating lights (16 mm, industrial grade LEDs).
  • Source acceptability indicating lights with true indication of the acceptability of each source, as determined by the voltage, frequency, voltage unbalance, and phase sequence settings of the control panel (16mm, industrial grade LEDs).
  • See diagram in the pictures above for layout.

Closed Transition Option

  • Features main contacts that overlap, permitting the transfer of electrical loads without power interruption.
  • Transfers in a make-before-break mode if both sources are within acceptable parameters.
  • Control logic continuously monitors source conditions and automatically determines whether the load transfer should be open (conventional non-overlap mode) or closed transition.
  • Closed-Transition transfer within 5 electrical degrees is achieved passively, without control of the engine generator set.
  • No additional control wire runs are required between the ATS and engine generator set governor.
  • Protective relaying may not be required under normal operation since the contact overlap time is less than 100 milliseconds (consult your local utility on protective relay requirements).
  • Extended parallel time protection standard. User interface provides visual indication when the pre-set extended parallel time has been exceeded. The controls automatically open the emergency or normal main contacts. Separate contact also available to shunt trip to an external breaker.
  • Failure to synchronize indication standard. User interface visually displays a failure to synchronize alarm if the time delay settings is exceeded, during closed transition transfer operation.
  • Transfer switch lock out with user interface indication standard. Prevents transfer in either direction if the extended parallel time is exceeded.
  • User interface alarm reset button. Resets extended parallel and failure to synchronize alarms.
  • Closed Transition bypass pushbutton on user interface allows transfer between sources in an open transition mode.
  • Please see the Asco 7000 Brochure below for withstand ratings (p5), screw-type terminal connections (p22), and dimensions/weights (p9).

Delayed Transition Option

  • Designed to provide transfer of loads between power sources with a timed load disconnect position for an adjustable time period.
  • Applications include older style variable frequency drives, rectifier banks, and load management applications.
  • Utilizes reliable, field proven solenoid operating mechanisms.
  • Mechanical interlocks to prevent direct connection of both sources.
  • Indicator light (LED type) for load disconnect position.
  • Adjustable time delay for load disconnect position.
  • Please see the Asco 7000 Brochure below for withstand ratings (p5), screw-type terminal connections (p22), and dimensions/weights (p9).

Bypass Isolation Option

  • Available in Open Transition, Closed Transition, and Delayed Transition configurations.
  • Allows the primary transfer switch to be inspected, tested, and maintained without any interruption of power to the load.
  • Provides redundant power transfer in the event the transfer switch is disabled or removed from service.
  • Bypass switch and transfer switch have identical electrical ratings.
  • Heavy duty mechanical interlocks prevent undesirable operation.
  • Bypass contacts carry current only during bypass mode.
  • Transfer switch is drawout design for ease of maintenance (see p6 of the Brochure below for details).
  • Bypass and isolation handles are permanently mounted. The bypass switch has dead front quick-make, quick-break operation for transferring of loads between live sources.
  • Bypass switch is fully rated for use as a manual 3-position transfer switch.
  • Bypass and isolation functions are simple, requiring a total of two operating handles.
  • No toggle switches, push buttons, selector switches or levers are required for bypass-isolation operation.
  • Mechanical indicators show bypass and transfer switch positions.
  • For more information and visual demonstration, please see these Asco 7000 Bypass Isolation videos.
  • Please see the Asco 7000 Brochure below for diagrams (p7), withstand ratings (p5), and screw-type terminal connections (p22). Please call for dimensions and weight information.
