7000 Series When Critical Power Protection is Essential Automatic Transfer Switches THE POWER AUTHORITY
Critical Loads Demand Healthcare Facilities Commercial Buildings/Industrial Buildings Data Processing Telecommunications Centers Process Manufacturing As we become more dependent on the quality and reliability of electrical power, interruption or complete loss of power can create serious and even crippling financial losses, or impose dangers to life and safety.
The Recognized Leader in Power Transfer Switch Technology Offers the Most Advanced Automatic Transfer Switches in the World. 7000 Series ASCO Automatic Transfer Switches are the standard of the industry. High speed transfer of loads between alternate sources of power, regardless of ampacity size, is achieved by a reliable, field proven solenoid operating mechanism.
7000 Series Switching Solutions Closed-Transition Transfer Switching ASCO Automatic Closed-Transition Transfer Switches feature main contacts that overlap, permitting the transfer of electrical loads without power interruption. The switch 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.
7000 Series Switching Solutions Non-Automatic Transfer Switching ASCO Non-Automatic Transfer Switches are electrically operated units which are operated with manual control switches mounted locally or at remote locations. • Sizes from 30 through 4000 amperes. • Microprocessor based controller provides for addition of optional accessories. • Controller prevents inadvertent operation under low voltage conditions.
7000 Series Switching Solutions Automatic Transfer Bypass-Isolation Switching ASCO Automatic Transfer & Bypass-Isolation Switches are available in open transition, closed transition and delayed transition designs. The bypass and isolation features allow power transfer switches to be inspected, tested, and maintained without any interruption of power to the load. • Available 150 to 4000 amperes. • Bypass switch and transfer switch have identical electrical ratings.

7000 Series Microprocessor Controller The 7000 Series Microprocessor Based Controller is used with all sizes of Automatic Transfer Switches from 30 through 4000 amperes. It represents the most advanced digital based microprocessor control panel in the industry and includes, as standard, all of the voltage, frequency, control, timing and diagnostic functions required for most emergency and standby power applications.
7000 Series Microprocessor Controller Features • The same controller can be used for open, closed and • Selectable multi-language display (English, German, delayed transition control sequences. Digital microprocessor. Touch pad programming of features and settings without the need for meters, variable power supplies and reference manuals. Sixteen (16) selectable operating voltages available in a single Controller.
7000 Series User Controls and Indicators Control Switches and Indicating Lights for Conventional 2-Position Switches • 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).
7000 Series Transfer Control Center Screens Status System Status Normal OK Load on Normal Displays system status in clear, concise language. Message shown indicates normal source is acceptable and the load is connected to the normal source. Time Delay Status Source Status Normal Source Vab=480V....................ABC Vbc=480V.........Vunbal=1% Vca=480V................60.0Hz Displays voltage for each phase, frequency, phase rotation and voltage unbalance for both normal and emergency sources.
7000 Series Optional Accessories Time Delays Neutral Conductor Options 2C An extended time delay on engine starting. Adjustable from 0 to 60 min in 1 second steps. Factory set at 5 minutes. • Note: 7000 Series controller provides a similar standard time delay which can be extended to 60 minutes with an external 24 volt DC source. • • Solid neutral, with fully-rated terminals. (AL-CU) UL Listed. Conventional neutral switching pole. Overlapping neutral transfer contacts.
7000 Series Optional Accessories Data Monitor The ASCO PowerQuest Data Monitor is a microprocessor based metering device that provides real-time measurements of single and three phase power systems. The Data Monitor uses digital signal processing technology to measure voltage and current per phase; real, reactive and apparent power, and bi-directional energy. All measurements are viewed locally with a backlit liquid crystal display and can be displayed remotely with ASCO PowerQuest products.
VPi The ASCO PowerQuest VPi monitoring and control management system is available in a windows operating system that allows the monitoring and control of transfer switches and engine generators from a personal computer. With an ASCO modem connection, you can remotely access and/or control your emergency power system, from around the corner or around the world.
VPi Data Monitor Detail Screen • Voltage: phase to phase; phase to neutral and voltage unbalance. • 3 phase currents and neutral (optional). • Frequency. • Kilowatt hours - normal and emergency. • Status and control of (4) digital outputs. • Status of (8) digital inputs. • Device ratings: CT and PT ratio. Transfer Switch Detail Screen • ATS rating and identification data is displayed. • Allows remote testing and time delay bypass.
