6 Commissioning

Warning
• During commissioning, unexpected and hazardous conditions can arise in the entire installation due
to defective adjustments, defective components or incorrect electrical connections. Remove all
persons and objects from the hazardous area.
• Do not start the fan until all safety instructions (EN 50110, IEC 60364-1)have been checked, the fan
is out of range (EN ISO 13857)and danger can be ruled out.
A-rated sound power levels of over 80 dB(A) are possible, see product catalogue.
•
6.1 Before first-time start-up
Observe the following points before the initial start-up:
1. Installation and electrical connection have been properly completed?
2. Has any leftover installation material and other foreign material been removed from the fan area?
3. That safety devices -if necessary- are mounted (EN ISO 13857)?
4. The impeller is out of reach?
5. Are the drain holes (as far as available) open or respectively closed according to the suitable
installation position?
6. Connection data complies with the specifications on the rating plate?
6.2

During start-up

Observe the following points during start-up:
1. Check the direction of rotation, see rotation direction arrow on the fan blade, impeller base plate, support
plates on suction side or rating plate.
2. Ensure even, low-vibration running. Significant vibrations due to uneven running, e.g. due to transport
damage or improper handling, can lead to damage and subsequently to failure.
3. Fans are Systemair GmbH delivered balanced in compliance with DIN ISO 21940-11 for the corresponding
fan category as set out in ISO 14694. After installation, check the fan for mechanical vibrations and
resonances in accordance with ISO 14694. If the limit values for the corresponding fan category are
exceeded during start-up, see section f, the entire system must be checked and the vibrations reduced.
System start-up is not allowed until the limit values are observed.
a. Time frame for checking the vibration values:
On a new system or a new device
•
– If necessary in the event of factory acceptance.
– At the installation site at the time of proper start-up of the system or device at the latest.
b. Measuring device and sensors:
It is recommended that measurement is performed with a resolution based on the r.m.s. (root-mean-
•
square value), a measurement interval of 1 s and a ramp-up time of 180 s.
At the same time, precisely timed measurement of the speeds is necessary so that the vibration values
•
can be assigned to the speed.
• Perform the measurement over the entire fan speed range.
• Perform the measurement in all 3 axes, see Point c.
