Position
Sensor out
of range
One or more of
the analog
variables
(position,
pressure or loop
current) does
not have
enough span to
calibrate
accordingly
Check:
The position sensor (Hall-effect sensor) connector and cable. .
See Figure 5-1 and find the connector J6 for local or remote
sensor connection for the ICoT 5400. See
Figure 6-3 and find the connectors J3 and J4 for remote
sensor connection for the ICoT 6400. The connector J2 is
used for local sensor connection for the ICoT 6400.

Magnet assembly:
o
For rotary magnets check if it is not rotated 90
degrees.
o
For linear magnets, check if the magnet assembly
center is matching the actuator mid position
•
Set-point stability, current generator, grounding issues,
cable shield is grounded properly, cables entry ground is
properly connected to a clean ground reference.
•
Pressure supply stability, actuator and tubing leaks.
•
Remove power for at least 1 minute, perform a factory
default initialization (see Section 9.2.2.4) and retry a full
auto CAL.
•
Grounding issues, cable shield is properly grounded;
positioner ground is properly connected to a clean
ground reference.
•
Sources of electromagnetic noise too close to the sensor
or to the positioner cables, like AC cables for motors,
inverters, etc.
