5 Using Fan Control Series 591
See Figure 5. The system is designed to be used in a dry environment in
combination with other Nederman products for extracting fumes, smoke or dust.
5.1 Automatic regulation of fan
(Only products with sensor.) Fit the sensor clamp on the welding cable. Check
before welding begins that the sensor clamp is in place.
The sensor stops the fan automatically after completion of welding with a
delay time of approximately 1 min. (could be adjusted). The sensor responds to
welding currents from 8 to 400 A. The sensor has a LED (A) which indicates
when the sensor has received a signal.
5.2 Manual regulation of fan
The fan can be started or stopped with the switch B or with the switch on the
fume extractor hood.
WARNING! Risk of personal injury.
• Check, after the products has been installed, that there is enough suction
capacity in the ducting system before any work has begun. Check the fan
impeller rotation direction.
• The equipment is not to be used in an explosive environment.
