8.2.2. Adjusting the dump valve sensor
1. Stop the conveying cycle by
disconnecting the dump valve
sensor from the controller. With the
dump valve sensor disabled, no
demand will be indicated, and
conveying will stop.
2. Connect an ohmmeter to PINS 2
and 3 of the dump valve sensor.
3. Release the nuts (A) of the dump
valve sensor (B) until the support
can be displaced.
4. Open the dump valve (C) so far that
the front tip of the outlet flap is
approx. 1.2” (30 mm) away from the sealing surface.
5. Displace the dump valve sensor (B) until the contact of the magnet switch is closed.
6. Tighten the nuts (A) of the dump valve sensor.
7. Check the adjustment: In case of free hanging dump valve (empty hopper loader) the
contact of the magnet switch must be closed.
8. If the dump valve sensor cannot be properly adjusted, replace the dump valve and
magnet or the sensor.
