7. Follow-up
After switching off the current stage, the fan turns off after the set run time. The
length of the overrun time is adjusted by the DIP switches 3 and 4 (6, 10, 15, 21
minutes). If you switch between stages, the delay time will be ignored. By
simultaneous shut down of the both stages, applicable delay time can be ignored. As
always, the technical signal is faster, so the controller response will depend on the
last signal.
Cleaning
Safety instructions listed in Chapter 1.2 should be observed!
- Before cleaning always ensure that the fan is isolated from the power supply and
secured against restarting!
- Clean cover, protective guard and visible housing parts (the external housing of the
fan) with a damp cloth!
- Do not use any aggressive or paint solvent cleaning agents!
- High pressure cleaners or water sprays should not be used!
Cover dismantling
1. Isolate the fan from the power supply and secure against restarting.
2. Pull the side pieces (cover plates) of the upper part of the housing outwards (see
Fig 1/Fig 2) to un-latch it and upwards until the cover plate is opened.
