Trouble Shooting:
1.
Blower does not reach operating speed when starting:
1.1 Check that the incoming voltage and frequency corresponds with the motor data plate.
1.2 Check the connections on the motor terminal block.
2.
Motor starter cuts out blower:
2.1 Problem as per 1.1 and 1.2.
2.2 Incorrect setting on the motor starter.
2.3 Motor starter trips too fast.
Solution: Use a motor starter with a time delay trip (version as per IEC 947-4).
2.4 Blower is overloaded, i.e. pressure difference is too high.
Solution: Increase the inlet or outlet diameter of the application, on pipework increase the diameter of the pipework, avoid restrictions in the
line. Limit the pressure difference by limitation valves (optional extra).
2.5 Motor rating selected was too small.
Solution: If available use a blower with the next motor size (exchange of the motor only is not possible).
3.
Required pressure difference cannot be achieved:
3.1 Blower or motor rating selected was too small.
3.2 Filters are contaminated.
3.3 Pressure loss into pipework too high.
Solution: Use bigger pipe diameter, avoid restrictions.
3.4 Leaks on the system.
4.
Blower operates at an abnormally high temperature:
4.1 Ambient or suction temperature is too hot.
4.2 Pressure difference is higher than permitted.
4.3 Cooling air flow is restricted.
5.
Exhaust noise at (B
) and / or suction noise at (A
1
Solution: Use an additional silencer ZGD (optional extra).
Appendix:
Repair on Site: For all repairs on site an electrician must disconnect the motor so that an accidental start of the unit cannot happen.
All engineers are recommended to consult the original manufacturer or one of the subsidiaries, agents or service agents. The address of the nearest
repair workshop can be obtained from the manufacturer on application.
After a repair or before re-installation follow the instructions as shown under the headings "Installation and Initial Operation".
Lifting and Transport: To lift and transport units SKK above size 302 02 the eye bolt on the unit must be used.
The weight of the blowers is shown in the accompanying table.
Storage: SKK units must be stored in dry ambient conditions with normal humidity. We recommend for a relative humidity of over 80% that the
pump units should be stored in a closed container with the appropriate drying agents.
Disposal: The wearing parts (as listed in the spare parts lists) should be disposed of with due regard to health and safety regulations.
