Under normal operating conditions, the analog output signal of the 815PT will remain
between 4mA and 20mA. In the event that the pressure goes beyond the normal
operating range of the device or in a fault condition, the 815PT will indicate the
condition on the 4-20 mA loop. The table below summarizes the 815PT loop current
with the associated fault indication.
