Message Meaning Solution
Comp range
error
An unknown
error has
occurred during
calibration
Check:
 Remove power for at least 1 minute and retry
 Remove power for at least 1 minute, perform a factory default
(see Appendix I) and retry a full auto CAL
 Call factory for additional support
Valve stuck Problems in the
movement
detection during
calibration
Check:
 Hall sensor connector and cable, especially if remote (see
Figure 3-4, connector J8)
 Magnet assembly.
o For rotary magnets check if it is not rotated 90
degrees (see figures 3.2, 3.3 and 3.4).
o For linear magnets, check if the magnet assembly
center is matching the actuator mid position (see
figures 3.5, 3.6 and 3.7)
 Pressure supply stability
 Actuator and tubing leaks
 Manifold and transducer assembly are tightly coupled to the
enclosure and there are no leaks
 Check if the cable between the inner canister and the
pneumatic transducer assembly is tightly connected
 Actuator/Valve assembly integrity
 Try to repeat a full auto CAL
 Call factory for additional support
Not possible
to set down
gain
The calibration
of the position
sensor could not
find a proper
gain to work
with the current
Hall sensor and
magnet
assembly
Check:
 Hall sensor connector and cable, especially if remote (see
Figure 3-4, connector J8)
 Magnet assembly is in correct position.
o For rotary magnets check if it is not rotated 90
degrees (see figures 3.2, 3.3 and 3.4).
o For linear magnets, check if the magnet assembly
center is matching the actuator mid position (see
figures 3.5, 3.6 and 3.7). Check if the proper fail-down
or fail-up magnet is being used (figure 5.1)
 Try to repeat a full auto CAL
 Try to replace the Hall sensor and/or the magnet
 Remove power for at least 1 minute and retry
 Remove power for at least 1 minute, perform a factory default
(see Appendix I) and retry a full auto CAL
 Call factory for additional support
