2.2

Leveling

Select a location for the

Counterpart

that is reasonably level and free of vibrations and air currents. Adjust the

four corner feet on the scale base and refer to the bubble level on the inside frame. The base should not rock and
the feet should have solid contact with the surface.

Ensure the nut on each foot’s bolt is secured flush against the scale base.

2.3

Enclosure Disassembly

The

Counterpart

indicator enclosure must be opened

to connect cables for load cells, communications, and
digital inputs/outputs.

Before opening the unit, ensure the unit
is turned off and the power cord is
disconnected from the power outlet.

The power outlet must be located near the indicator to
allow the operator to easily disconnect power to the unit.

Ensure power to the indicator is disconnected, then
place the indicator on an antistatic mat. Remove the
four screws holding the top plate to the enclosure
body and set them aside. Gently lift the top plate away
from the enclosure and disconnect any cables and set
it aside.

2.4

Making Power Connections

The power source used for the

Counterpart

must be

properly grounded to an acceptable earth ground and
the outlet must be a grounded outlet. If the scale is
remotely mounted, the platform must be separately
grounded from the chassis ground screw located on
the bottom of the platform. Connect this screw with
18 gauge wire to the same earth ground system as the
AC power source. Failure to ground the base may
cause static buildup that could cause damage to the
electronics and/or give incorrect weight readings.

2.5

Load Cell Wiring

On all complete units, the load cell has been wired to
the CPU load cell terminal at the factory. Wire the
cable to the CPU board’s J1and J2 connector as shown
in Table 2-1.

If using a 4-wire connection, set JP1 and JP2
to ON. If using a 6-wire connection, set JP1
and JP2 to OFF.
