Description | Unpacking When opening the transport packaging, there is a risk of damage from sharp edges, nails, staples, splinters etc. ♦ Unpack the fan carefully. ♦ Check the fan for obvious transport damage. ♦ Only remove the packaging shortly before assembly. Transport Safety information Warning: Electrical or mechanical hazards due to fire, moisture, short circuit or malfunction. ♦ Never transport the fan by the connecting wire, terminal box, impeller, protection grille, inlet cone or silencer.
| Description 5.3 Technical data Max. ambient temperature [°C] Table 2 Temperature types, page 4 Max. temperature of transported air [°C] Table 2 Temperature types, page 4 Sound pressure [dB] see data sheet, available in our online catalogue Voltage, current, frequency, enclosure class, weight see name plate of the fan The motor data can be found on the name plate of the motor, or in the technical documents of the motor manufacturer.
Name plate and type key | 6 Name plate and type key EN 12101-3 (2015) powered smoke and heat control ventilator 1 General data 2 Technical data 3 Temp./Time information/ only listed on smoke extraction fans 4 Certifications and QR— Codes 5 Manufacturer Address IV 50-4/8 (B) Type: Item no.: Serial.no: Date: Made In: 79013 1005405682-1 20210625 Germany 1 380-415V~ YY / Y Voltage: 50 Hz Frequency: 1,48 / 0,22 kW Nominal power at shaft (P2): 4,08 / 1,41 A Nominal current: 1458 / 736 r.p.m.
6 | Electrical connection Preconditions ♦ Ensure that the fan and all its components are undamaged. ♦ Ensure that the information on the name plates (fan and motor) matches up with the operating conditions. ♦ Fit the fans in such a way that there is sufficient access for installation, troubleshooting, maintenance and repair. ♦ A warning sign must be attached close to the air outlet, stating that the air outlet must not be covered. ♦ Protect against dust and moisture when installing.
Electrical connection | 8.1 Protecting the motor Important Damage to motor due to overcurrent, overload or short circiut. ♦ Lead-out temperature monitors must be integrated in the control circuit in such a way that, if a fault occurs, the motor cannot switch on again automatically after it has cooled down. ♦ Motor lines and temperature monitor lines should be laid separately on principle.
8 | Electrical connection 8.2 Wiring diagram IV Important Wrong connection can damage or destroy the motor. ♦ Use the information on the nameplate to select the correct connection diagram.
Electrical connection | IV...EC Important External voltage can damage or destroy the motor. ♦ Do not apply any external voltage which is not specified in this manual to the terminals.
10 | Electrical connection Control output reference (tacho) B = customer side A = fan side Important The applied voltage and the value of the pull-up resistor must be selected that the current does not exceed 20 mA. Frequency = speed (rpm) * 0,6015 Example: 669 Hz / 0,6015 = 1112,21 rpm -> 36 impulse / revolution open collector circuit 8.3 Variable-speed fans (Frequency converter / EC motor) Risk from resonant frequencies. ♦ Only operate the fan outside these speed ranges.
Commissioning | 9 Commissioning Warranty claims can only be made if commissioning work is carried out correctly and written evidence thereof is provided. Safety information ♦ Observe 2 Important safety information, page 1 Preconditions ♦ Installation and electrical connection have been correctly performed. ♦ Inlet and outlet are free. ♦ Before switching the fan on, check for externally visible damage and ensure that the protective equipment functions properly. ♦ Safety devices have been fitted.
12 | Troubleshooting/maintenance/repair Impeller rotates in wrong direction. Air output of fan too low Grinding sounds when starting or operating the fan Thermal contacts/ resistors have triggered Fan does not reach nominal speed Motor does not rotate Electronics/motor overheated AC motor Change direction of rotation (swap two phases in case of a 3– phase motor). EC motor Contact Systemair Wrong wiring configuration (e. g. Y instead of Delta). Check and possibly correct the wiring configuration.
Troubleshooting/maintenance/repair | 6 Overvoltage 0.25 0.25 2 9 Communication timeout Failure in the drive to motor communication. 0.25 0.25 2 10 Watchdog timeout Failure in the drive processor (Software) 0.25 0.25 2 11 Locked rotor 0.25 0.25 2 Note: For all other damage/defects, please contact Systemair. Defective safety-relevant fans (for Ex and smoke extraction applications) must be replaced completely.
14 | Cleaning Table 7 Activities for fans used for emergency operation. Activity Check (if present) Every six months Operational readiness of the fan unit Allow the fan to run for 1 hour X Operational readiness of the emergency system Allow the "emergency" system to run for 15 minutes X Function of the “emergency” control Test whether the “emergency” control effectively bridges all the other controls and switches X Spare parts ♦ Use original spare parts from Systemair only.
Deinstallation/dismantling | 13 Deinstallation/dismantling Deinstall and dismantle the fan in reverse order of installation and electrical connection. 14 Disposal ♦ Ensure material is recycled. Observe national regulations. ♦ The device and the transport packaging are predominantly made from recyclable raw materials. ♦ Disassemble the fan into its components. ♦ Separate the parts according to: • reusable material • material groups to be disposed of (metal, plastics, electrical parts, etc.
