Connecting Groscale To Compass - Priva Compass Installation Manual

support lock. The support plate onto which the weighing indicator is mounted is then slid onto the
support arm and bolted using the wing nut. Proceed as follows:
1. Fit the support lock, the support arm and the weighing indicator in such a manner that they do
not interfere with any existing overhead heating. This also applies to any cabling running to the
process computer and weighing platforms. The overhead heating needs to move freely either
in front or behind the unit.
2. Fit the weighing indicator at the correct operating height and check that the connecting cables
of the weighing platforms are sufficiently long.
3. Open up the weighing indicator and let the control panel hang from the earth-wires.
4. Feed the weighing platforms' connecting cable plugs around the back of the control panel and
plug them into connectors L1-L4. The sequence does not matter.
Make sure you place the plugs correctly when plugging them into the connectors and
that all pins are rightly inserted.
5. Push the connecting cable grommet into the holes in the edge of the housing.
6. Roll up excess lengths of cable and hang these onto the side of the weighing indicator.
Never shorten the cables of weighing platforms!

1. Unscrew the weighing indicator to open it and allow the operating panel to hang from the ground
wires.
2. On account of the removal of the weighing indicator during crop change, do not feed the
connecting cable to the process computer through the tube. Also remove this from behind the
operating panel, as well as the connecting cables of the weighing platforms. Position the supplied
grommet over the cable. This is absolutely necessary in order to achieve a watertight sealing of
the housing.
3. Connect the cores of the twisted pairs to the supplied plug in accordance with the table above.
4. Use two pairs per terminal for the power supply.
5. On the process computer side, the shielding of the connecting cable is connected to the earth
strap.
6. Fit the plug cap, slide the grommet to the correct length, fit a hose clip as strain relief and press
the grommet into the appropriate hole in the housing.
7. Feed the cabling through the cable glands.
8. Close the weighing indicator by screwing it tight.
Make sure that the 24VAC/24VDC and 0VAC/0VDC are electrically isolated from the DAC1gnd
and DAC2gnd. With the twisted pair, it can easily be mixed up, which leads to errors. Be sure
to check this again!
