Speed Control Settings
The blower supports 0-10 VDC and PWM speed control. The maximum recommended PWM amplitude is 10 VDC. Connect all power and control wires strictly according to the wiring diagram.
Note
- Connect the power and control lines in the order shown in the wiring diagram to prevent damage to the fan.
- Do not connect the white signal wire directly to the red signal wire or an external DC power supply.
- If the fan does not operate after power-on, check the speed-control input voltage and wiring. Do not touch the impeller or rotor while energized.
- The fan takes several seconds to start. Keep clear of the impeller and rotor while energized or operating at low speed.
- The fan must be used only by persons with suitable knowledge or under the guidance of responsible safety personnel. Keep children away from the product.
- If the power cable is damaged, it must be replaced by the manufacturer.
- The motor is part of the fan and must not be operated without an impeller or load.
- After unpacking, repackage the product if it must be stored. Store it in a clean, ventilated warehouse at -40°C to +80°C and relative humidity not exceeding 95%, without corrosive gas, at least 15 cm above the ground.
- Read this technical specification carefully before use.
