4.5 Making connections
4.5.1 Compressed air connection
Connect the air hose [1] to the compressed air connection of the unit [2].
Check the operating pressure with the manometer [3] and if it is different set it
to 0.6 MPa.
Fig. 6: Connecting compressed air
No additional compressed air consumers may be connected to the unit, be-
cause this may reduce the operating pressure. If the operating pressure is
less than 0.6 MPa the loading precision may be affected.
NOTE
4.5.2
Electrical connection
Connect the gravimetric batch blending unit to the mains power-supply system.
Check that the unit functions after assembly (see 7.7 Startup).
Electrical supply must be a clean power source with nothing else on the cir-
cuit (for example self-loading loaders.) The unit must be grounded to a lug by
the sensor on the back of the unit.
NOTE
Edition: February 2007
The operating pressure must be at least 0.6 MPa (87.0 psi) (6 bar).
