♦ Cable shields must connect to ground only through the BW500 or BW500/L Motherboard
(TB15). They should not be grounded to the LVDT Conditioner Card enclosure or any other
location.
* Where separation between the BW500 or BW500/L and LVDT conditioner exceeds 150 m
(500 ft):
1. remove jumpers from BW500 and BW500/L terminal 11/12 and 13/14
2. run additional conductors from:
BW500 terminal 12 to integrator terminal block '+EXC'
BW500 terminal 13 to integrator terminal block '-EXC'
Note
•
LCA (Terminal 2) is jumpered to SHLD (Terminal 5), which internally connects to the load
cell circuit common.
•
Do not connect to the Speed Sensor (Terminal 17) common, it is isolated from the load
cell circuitry.

Constant Speed (No Sensor)
If a speed sensor is not used, a jumper or
contact closure must be co
nnected across
BW500 and BW500/L terminals 17 / 18 when
the conveyor is running. If a speed sensor is
used, ensure that the jumper is removed.
Note:
With contact closed or jumpered when
the conveyor is idle, the integrator will conti
n-
ue totalizing.
