CAUTION!
Disconnect any external load cell power supply before connecting
load cells to the indicator. Failure to do so will result in permanent damage to the
indicator.
INSTALLATION, CONT.
Load Cell Connection
Load Cell Cable Connection for RFI Suppression
The load cell cable should be routed through the special metallic gland connector and the
shield wire must be connected to this gland connector for grounding and to eliminate RFI.
Refer to Figure No. 2 and Figure No. 3 for the appropriate gland connector.
1. If using a battery, remove the three acorn
nuts securing the Battery Access Cover to
the bottom of the indicator and remove the
battery.
2. After removing the battery, remove the 12
acorn nuts securing the back panel to main
housing.
3. Loosen and remove the metal gland
connector nut and remove the plastic insert.
4. Route the load cell cable through the nut and
plastic insert and into the enclosure.
5. With the load cell cable routed into the
enclosure, remove approximately 18 to 20
inches of the outer insulating jacket from the
cable exposing the internal wires.
6. Cut the shield wire so that it extends past the
outer jacket approximately 3/4 inch.
7. Remove 1/4" of insulation from the end of
each of the 4 wires (without sense leads) or 6
wires with sense leads (refer to figure No. 4).
8. Connect each of the wires to terminal block
P1 referring to labels on circuit board for
terminal connections. Refer to Figure No. 7
for terminal block location.
9. To terminate a wire, press down on release
bar for the terminal, insert wire into terminal
opening then allow release bar to return to its
original position, locking wire in place.
Repeat procedure until all wires are in place.
10. Route load cell cable wires through the two
cable clips provided on upper and left sides
of enclosure interior.
LOAD CELL TERMINAL BLOCK P1
TERMINAL NO. Function TERMINAL NO. Function
1 + EXCITATION 5 - SIGNAL
2 + SENSE 6 - SENSE
3 + SIGNAL 7 - EXCITATION
NOTE! If the sense leads are NOT used, you must install plug-in jumpers at J4 and J5
adjacent to the terminal block. These jumpers attach the sense leads to the excitation leads.
If sense leads ARE used (as in motor truck scales), these plug-in jumpers should be positioned
on one plug-in pin only or removed and stored for later use (see Figure No. 8).
