The cable of the PT 100 sensor or a twisted shielded
cable should be used for the analog input cable. This
analog input cable should be wired separately from
power lines or any other lines which may induce noise.
The three wire method improves the accuracy of the
sensors by compensating voltage drops.
If there is electrical noise, connect the frame ground
terminal (FG) with the ground terminal.
Connect the ground terminal on the FX
with the grounded terminal on the base unit. Use
class 3 grounding on the base unit, if grounding is
possible.
Either an external or the 24V built-in supply in the
programmable controller may be used.
