ASSEMBLY
The Indicator housing has liquid-tight cable
connectors for load cell, communication (I/O),
and AC power, as shown.
To open the housing, remove two screws on
either side, and gently fold the front panel away
from the rear panel.
Pass the load cell cable through the liquid-tight
connector and the large ferrite bead attached to
a plastic clip. Remove the screws holding the
switch cover plate. Connect the load cell cable
and wires as indicated on the diagram below.
Adjust Jumpers to match the load cell:
For a 2 mv/v load cell: short W1.
For a 3 mv/v load cell: open W1.
For a 4-wire load cell with no sense wires:
short both W2 and W3. For a 6-wire load cell
with sense wires, open W2 and W3.
For a load cell with an extra ground shield
wire, connect the shield wire to “GND” on J2.
