Typical Error Conditions
The PIE 525Plus is supplying the loop voltage. A calibrated
transmitter is limiting the loop current to 12.00 mA. An
additional 0.51 mA is not controlled by the transmitter and
is leaking somewhere in the loop.
The PIE 525Plus is supplying the loop voltage. There is a
control loop error. This may be a transmitter (set for
upscale burnout) with a bad or missing sensor, or a short
in the loop. The red ERROR LED will also flash.

Note:
Many loops with installed transmitters will normally
indicate 0.01 to 0.02 mA leakage without significant control
problem. Unstable readings may indicate loose connections or
the presence of moisture.
