Product information:
The device is used to detect adjustment device, and confirm to the
IEC60598-1 clause 4.14.3.
The adjustment device, equipped with the appropriate cable or cord
shall be operated in accordance with following table. A cycle of
operation is a movement from one extreme of the range to the other
and back to the starting position. The rate of movement shall not
cause the device to heat appreciably and shall not exceed 600
cycles per hour.
For adjusting devices that consist of a flexible tube, the range of
adjustment for this test is normally 135° in both directions from
the vertical. However, where this adjustment cannot be achieved
without using unreasonable force, the flexible tube is bent only to
the positions where it will remain by itself.
Test on adjusting devices:
Type of luminaire | Number of cycles of operation |
Luminaires intended to be frequently adjusted, | 1500 |
Luminaires intended to be occasionally adjusted, for example shop-window spotlights | 150 |
Luminaires intended to be adjusted during installation only, for example floodlighting luminaires | 45 |
