Rice Lake IQ 700 Configurable Weight Indicator - Manual (Page 11)

Installation and Wiring 7
The standard connection is designed for 4-wire (non remote sensing) use. To convert to 6-wire (remote sensing)
applications, cut the two PC traces on either end of TB1 as shown in Figure 2-6.
Figure 2-6. Load Cell Wiring From Indicator
NOTE: The load cell shield wire should be connected
to one of the load cell cable clamp screws located on
the load cell mating connector.
Shielding is connected at only one end
(typically at the indicator end). If
connected at the strain gauge end,
disregard Figure 2-7.

2.9 Standard Surge Protection Board
The IQ 700 digital indicator comes with a factory installed surge suppression board. The suppression board stops
the flow of excess voltage to the CPU board and attaches to TB1 on the CPU board just by pressing it onto TB1 and
tightening the connector screws.
