Load Cell Cable Connection (Standard Gland Connector); Load Cell Connections With Over 30 Feet Of Cable - Cardinal 210 Installation And Technical Manual

Load Cell Cable Shield Wire Connection for RFI Suppression
After all terminations have been made,
1.
remove the excess cable from the enclosure.
Referring to Figure No. 5, fold the shield wire
2.
back over the plastic insert and then insert the
plastic insert (with the shield wire) into the
gland connector.
The shield wire is secured when tightening the
3.
gland connector nut.
Do not over-tighten the connector but make
4.
certain it is snug.
DO NOT USE TOOLS! Finger-tighten only!
5.
Load Cell Cable Connection
The following instructions describe the load cell connection should it be desired to route the
load cell cable through a standard gland connector.
Remove the 12 acorn nuts securing the back panel to main housing, and then loosen a
1.
gland connector for the load cell cable. Refer to Figure No. 2 for illustration of connector
layout.
Slip the single cable from the load cell or load cell junction box through the gland connector
2.
and into the enclosure.
Remove 3" of the outer insulation jacket then remove 1/4" of insulation from each of the 4
3.
wires and shield (without sense leads) or 6 wires and shield (with sense leads). Refer to
Figure No. 4.
Connect each of the wires to terminal block P15 referring to labels on circuit board for
4.
terminal connections. Refer to Figure No. 15 for terminal block location.
To terminate a wire, first press down on release bar for the terminal, insert wire into
5.
terminal opening then allow release bar to return to its original position, locking wire in
place. Repeat procedure until all of wires are in place.
Route load cell cable through the two cable clips provided on upper and left sides of
6.
enclosure interior.

NOTE: If the sense leads are NOT used, you must install plug-in jumpers at J6 and J9
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. 15).

Load Cell Connections with Over 30 Feet of Cable

For installations with over 30 feet of cable between the indicator and the load cells, sense
wires should be used. The sense wires must be connected between the +SENS, -SENS
terminals on the indicator and the +EXCITATION, -EXCITATION wires of the load cells or the
+SENS, -SENS terminals of the load cell trim board or the section seal trim board.
