Need help?Do you have a question about the ZIEHL-ABEGG Fcontrol Basic FSDM Series and is the answer not in the manual?
This document describes the Fcontrol Basic series FSDM2.5...50M, a frequency inverter designed for controlling fan speeds. It integrates a sine filter for 3-phase applications, making it suitable for a variety of industrial and commercial ventilation systems.
The Fcontrol Basic is a frequency inverter that provides precise speed control for fans. It operates by converting the incoming AC power into a variable frequency and voltage output, which in turn controls the speed of a connected 3-phase motor. The integrated sine filter ensures a clean sinusoidal output current, which is beneficial for the motor and the electrical grid by reducing harmonics. This device supports various input signals for speed control, including 0-10 V, 0-20 mA, and 0-100% PWM, allowing for flexible integration into different control systems. It is designed for continuous operation and offers features like motor protection, fault diagnostics, and options for external control and monitoring. The inverter is suitable for applications where precise and efficient fan speed regulation is required, contributing to energy savings and optimized ventilation performance.
The FSDM2.5...50M series covers a range of power outputs, from 2.5 A to 50 A, with corresponding motor power ratings. The rated voltage is 3~ 208...480 V (-15% to +10%), 50/60 Hz. The maximum output voltage is approximately 95% from the mains voltage, and the maximum output frequency ranges from 48.5 Hz (1-120 Hz). The U/f-characteristic curve is quadratic (linear). The switching frequency is 16 kHz. Ramp-up and ramp-down times are adjustable, ranging from 20 ms to 1 second for FSDM2.5...16 and 20 ms to 1 second for FSDM22...50. The current limit is 125% (100-130%). The power factor is 0.9.
Input resistance for speed setting signals varies depending on the type: 0-10 V input has R_i = 300 Ω, 0-20 mA input has R_i = 500 Ω, and PWM input has R_i = 210 kΩ. Digital input "D1" has an input resistance of approximately 4 kΩ, with a voltage range of high level: 10...30 V DC and low level: 0...4 V DC. The voltage supply for external devices is +24 V ± 20%, Imax 70 mA. Power loss in standby is approximately 10 mA (short-circuit-proof). The maximum contact rating of the relay is 2 A / 250 V AC. The maximum permissible ambient temperature for operation is 55 °C. The minimum permissible ambient temperature is 0 °C (if mains voltage is not switched off up to -20 °C). Permissible temperature range for storage and transport is -30...+80 °C. The installation height is 0...4000 m amsl. The maximum permissible output current is current indication name plate minus 5% / 1000 m. The maximum permissible line voltage is max. voltage indication name plate minus 12.9% / 100 m. Permissible relative humidity is 85% no condensation. The device complies with EMC standards EN IEC 61000-6-3 (domestic household applications) and EN IEC 61000-6-2 (industrial applications). Harmonics current compliance is according to EN 61000-3-2 (see Electrical installation / Harmonics current). The housing protection is IP54.
The maximum load dependent on line voltage and ambient temperature varies. For example, at 40 °C and 208 V (-15%), the FSDM2.5(A)M has a maximum load of 2.5 A, while at 50 °C and 480 V (+10%), it has a maximum load of 1.6 A. Similarly, the FSDM50(A)M at 40 °C and 208 V (-15%) has a maximum load of 50.0 A, and at 50 °C and 480 V (+10%), it has a maximum load of 46.0 A.
The Fcontrol Basic is designed for ease of use and integration. It features a clear terminal compartment for electrical connections, with designated terminals for line, motor, indication relays, and control signals. The device supports various fastening methods, including 3 or 4 points depending on the model, ensuring secure mounting. Cable inlet options are provided for different cable sizes, with provisions for both factory-installed step nozzles and attached cable inlets for cable glands.
Commissioning involves checking the mains voltage, ensuring correct connections, and verifying the rating plate data. The device includes diagnostic features with LED indicators for operational status and fault conditions. Faults such as phase failure, IGBT fault, DC overvoltage, intermediate overvoltage, IGBT cooling down period, communication fault, line voltage too low/high, motor fault, sine filter to hot, and overload fault are detected and indicated, with corresponding remedial measures provided in the manual.
The inverter offers flexible speed setting options. For FSDM2.5...16 models, speed can be set via external control signals (0-10 V, 0-20 mA, or 0-100% PWM) or an external potentiometer. For FSDM22...50 models, similar options are available. The analog input "E1" is configurable for fan speed control, supporting 0-10 V, 0-20 mA, or PWM signals. Digital input "D1" can be used to enable/disable the device. Relay outputs "K1" provide potential-free contacts for status indications. A bypass circuit is available for bypassing the inverter, which can be controlled manually or automatically. Optional add-on modules, such as AM-MODBUS, AM-PREMIUM, AM-CAN-OPEN, AM-LON, AM-PROFIBUS, AM-ETHERCAT, AM-PROFINET, and AM-BACNET, extend the device's communication capabilities and integration into building management systems.
Maintenance of the Fcontrol Basic primarily involves ensuring proper installation and addressing fault conditions as they arise. The device is designed for durability and long-term operation, but regular checks are recommended.
Safety Precautions: Adherence to safety instructions is crucial during installation, operation, and maintenance. This includes disconnecting power before working on the device, ensuring proper grounding, and using appropriate personal protective equipment. Only qualified electricians should perform electrical work.
Fault Diagnostics: The device's diagnostic system helps identify and troubleshoot issues. When a fault occurs, the LED indicators provide visual cues, and the manual details the specific fault codes and recommended remedial actions. This allows for quick identification and resolution of problems, minimizing downtime.
Motor Protection: The inverter includes motor protection features, such as thermal contacts (TB/TP) that can be connected to the device. These contacts monitor the motor's temperature and trigger a shutdown if overheating occurs, preventing damage to the motor. The manual specifies how to connect and configure these thermal protectors.
Cleaning and Storage: The device should be stored and operated within specified temperature and humidity ranges. Regular cleaning of the exterior may be necessary to prevent dust and debris buildup, especially in industrial environments. However, care must be taken to avoid damaging internal components.
Spare Parts: In the event of a component failure, only genuine spare parts from ZIEHL-ABEGG should be used. The manual emphasizes that non-original parts are not approved and may compromise the device's safety and performance.
Software Updates: While not explicitly detailed as a maintenance feature, the use of communication modules might imply the possibility of firmware updates or configuration changes via software, which could be part of a maintenance routine for advanced systems.
Overall, the Fcontrol Basic is a robust and reliable frequency inverter with comprehensive features for fan speed control, designed for both performance and ease of maintenance in various applications.
