Speed setting
- Full speed: short the red +10 VDC wire to the yellow VSP wire.
- 0-10 VDC: the fan starts above 1.0 VDC and stops below 0.5 VDC.
- PWM: 10 VDC +/-5% amplitude and 1-10 kHz. The fan starts above 10% duty and stops below 5%.
- Potentiometer: use a recommended 10 kOhm potentiometer between red +10 VDC, yellow VSP and blue GND.
Tachometer feedback: 5 pulses per revolution. Fan speed n = 60f/a, where f is output frequency and a is pulses per revolution. The customer supplies Vfg and the pull-up resistor; Vfg = 3.3-30 VDC and R must be at least 1000 x Vfg ohms.
Notes
- Connect the power and control lines strictly according to the wiring diagram to prevent fan damage.
- Do not connect the white signal wire directly to the red signal wire or an external DC power supply.
- If the fan does not run after starting, check the speed-control input voltage and wiring. Do not touch the impeller or rotor after power is applied.
- The fan takes several seconds to start. Do not touch the impeller or rotor while energized or operating at low speed.
- Before switching on, confirm that the motor is installed securely.
- Do not pull the power cable. A damaged cable must be replaced by the manufacturer.
- Do not drop or strike the motor.
- Do not flush the motor; reduced insulation performance can cause electrical leakage.
- For applications outside the agreed operating conditions, consult Blauberg and obtain confirmation before use.
- The motor housing may remain hot shortly after the fan stops. Prevent direct contact and burns.
- During installation, keep the housing free of debris and clean the interior if necessary.
- Before installation and operation, rotate the rotor by hand and confirm there is no collision, interference or jamming.
- The motor is part of the fan and must not operate without an impeller or load.
- After unpacking, repackage the product for storage. Store it in a clean, ventilated warehouse at -40 deg C to +80 deg C, below 95% RH, without corrosive gases, and at least 15 cm above the floor.
- Install the fan out of reach of children and do not allow children to use it.
- The final interpretation of this specification belongs to Blauberg.
Life, maintenance and warranty
- Design life is 50,000 hours, limited by the ball-bearing life at 40 deg C. Actual service life depends on temperature, humidity, installation, fan load and other operating conditions.
- Clean and maintain the fan every 3-6 months according to the operating environment.
- The complete fan has a two-year warranty from the purchase date, subject to the delivery date. Product-quality failures are eligible for repair or replacement; damage caused by improper disassembly, handling, human action, natural disaster or force majeure is not covered.
