VLT ® Automation Drive FC 300
Instruction Manual High Power
Manual Motor Starters
Provide 3-phase power for electric blowers often required for larger motors. Power for the starters is provided from the load side of any supplied contactor,
circuit breaker, or disconnect switch. Power is fused before each motor starter and is off when the incoming power to the drive is off. Up to two starters
are allowed (one if a 30-amp, fuse-protected circuit is ordered). Integrated into the drive's safe-stop circuit.
Unit features include:
• Operation switch (on/off)
• Short-circuit and overload protection with test function
• Manual reset function
30-Amp, Fuse-Protected Terminals
• 3-phase power matching incoming AC line voltage for powering auxiliary customer equipment
• Not available if two manual motor starters are selected
• Terminals are off when the incoming power to the drive is off
• Power for the fused protected terminals will be provided from the load side of any supplied contactor, circuit breaker, or disconnect switch.
24 V DC Power Supply
• 5 amp, 120 W, 24 V DC
• Protected against output overcurrent, overload, short circuits, and overtemperature
• For powering customer-supplied accessory devices such as sensors, PLC I/O, contactors, temperature probes, LEDs, and/or other electronic
hardware
• Diagnostics include a dry DC-ok contact, a green DC-ok LED, and a red overload LED
External Temperature Monitoring
Designed for monitoring the temperatures of external system components, such as the motor windings and/or bearings. Eight signal inputs are each
brought to individual modules, each configurable for a different type of signal. Modules can communicate with one another and can be monitored via a
serial communication bus network (requires the purchase of a separate module/bus coupler). Integrated into the drive's safe-stop circuit.
Possible input signal types:
• RTD inputs (including Pt100), 3-wire or 4-wire
• Thermocouple
Additional features:
• One universal output, configurable for either analog voltage or analog current
• Two output relays (N.O.)
• Dual-line LC display and LED dignostics
• Sensor lead wire break, short-circuit, and incorrect polarity detection
In addition to the eight universal inputs described above, two dedicated thermistor motor protection modules are also included. Features include:
• One Type A PTC thermistors input per module (2 modules total*)
• Fault diagnostics for wire breakage or short-circuits of sensor leads
• ATEX/UL/CSA certification
* Note: A third thermistor input can be provided by the PTC thermistor
option card MCB 112, if necessary.
