The Drive provides full rated output current continuously, 110% of rated current for 60 seconds and 160% of rated current for up to 0.5 second while starting. FLD = Furnished by Trane / Installed by Others Trane Equipment Submittal Page 5 of 41 Fanno Creek Bldg B September 13, 2006 Isolation is provided between the Drive's power circuitry and control circuitry to ensure operator safety and to protect connected electronic control equipment from damage caused by voltage spikes, current surges, and ground loop currents. Audible motor noise is minimized through the use of an adjustable carrier frequency. Carrier frequency is automatically adjusted to optimize motor and AC Drive efficiencies while reducing motor noise. Operating range, ambient temperature, -10 to 50°C (14 to 104 °F), 0 to 95% relative humidity, non - condensing, AC line voltage variation, -10 to +10% of nominal with full output. Protective Features Class 10 12t electronic motor overload protection for single motor applications is provided. Protection against input transients, loss of AC line phase, output short circuit, output ground fault, over - voltage, under - voltage, AC Drive over - temperature and motor over - temperature. All faults are displayed in plain English. Protection from AC Drive sustained power or phase loss. Full rated output with an input voltage as low as 90% of nominal. Continuous operation with reduced output with an input voltage as low as 164 V AC for 208/230 volt units, 313 V AC for 460 volt units, and 394 volts for 600 volts units. Semi - conductor rated input fuses to protect power components. A "signal loss detection" circuit senses the loss of an analog input signal such as 4 to 20 mA or 0 to 10 V DC, and is programmable to react as desired in such an instance. Default: After 10- second time out the Drive will shut off. Will function normally when the keypad is removed while the AC Drive is running and continue to follow remote commands. AC Drive catches rotating motor operating forward or reverse up to full speed. The AC Drive is rated for 100,000 amperes interrupting capacity (AIC). Includes current sensors on three output phases to detect and report phase loss to the motor. Identifies which of the output phases is low or lost. Continues to operate without faulting until input voltage reaches 300 V AC on 208/230 volt units, 539 V AC on 460 volt units, and 690 volts on 600 volt units Interface Features Off /Stop and Auto /Start selector switches provided to start and stop the AC Drive and determine the speed reference. On units with bypass, an AC Drive /Off /Bypass Hand selector switch will be provided in the unit control box. In case of an external current overload, a normally closed dry contact will stop the motor whether in DRIVE or BYPASS mode. In DRIVE mode speed reference is provided by a 0 to 10 V DC analog input. The display is programmable to display in 9 languages including English, Spanish and French. The display has four lines, with 20 characters on three lines and eight large characters on one line. The following points are controlled and /or accessible: AC Drive Start/Stop. Speed reference, Fault diagnostics, Meter points to include - Motor power in HP, Motor power in kW, Motor kW -hr, Motor current, Motor voltage, Hours run, DC link voltage, Thermal load on motor, Thermal load on AC Drive and Heatsink temperature. The AC Drive stores in memory the last 10 faults and related operational data. Four simultaneous displays are available, frequency or speed, run time, output amps and output power. The following displays are accessible from the keypad. Reference Signal Value, Output Frequency in Hz or percent, Output Amps, Motor HP, Motor kW, kW hour, Output Voltage, DC Bus Voltage, AC Drive Temperature in degrees, and Motor Speed in RPM. A quick setup menu with factory preset parameters is provided on the AC Drive eliminating the need for macros. A red FAULT light, a yellow WARNING light and a green POWER -ON light are provided. These indications are visible both on the keypad and on the AC Drive when the keypad is removed. The AC Drive includes a standard EIA -485 communication port and capability for future connection to a Modbus communication interface. If the temperature of the AC Drive's heat sink rises to 80°C, the AC Drive automatically reduces its carrier frequency to reduce the heat sink temperature. If the temperature of the heat sink continues to rise the AC Drive automatically reduces its output frequency to the motor. As the AC Drive's heat sink temperature returns to normal, the AC Drive automatically increases the output frequency to the motor and returns the carrier frequency to its normal switching speed. The AC Drive has temperature controlled cooling fans for quiet operation and minimized losses. Adjustments and Factory Default Settings AC Drive carrier frequency is adjustable in steps of not less than 0.1 kHz to allow tuning the AC Drive to the motor. Four, acceleration and four deceleration ramps are provided. Acceleration and deceleration time is adjustable over the range from 0 to 3,600 seconds to base speed. The shape of these curves is automatically contoured to ensure no -trip acceleration and deceleration. Factory Default: The Drive is programmed for an acceleration and deceleration time of 30 seconds. Four current limit settings will be provided. Factory Default: The Drive is programmed for 1 X rated current. If the AC Drive trips on one of the following conditions, the AC Drive will be programmable for automatic or manual reset: under - voltage, over - voltage, current limit and inverter overload.
