R - - - Any sequence starting with a red light indicates that there is an operational problem with
the unit.
RGRR 25 Position Deviation - The position has exceeded user defined error band between com-
mand and position.
RYGG 26 Initializing, or LED test mode - This sequence should only be visible for 3 sequences
when powering up the unit.
RYYY 27 Hall sensor non-motion - Check to make sure the air supply is connected. This error may
be cleared by briefly pushing the Quick-Cal button, which will force the positioner to use
the parameters from the last good calibration. If the positioner still does not operate
replace the pneumatic relay assembly.
RYYR 28 Hall sensor lower position - Check to make sure the air supply is connected. This error
may be cleared by briefly pushing the Quick-Cal button, which will force the positioner to
use the parameters from the last good calibration. If the positioner still does not operate
replace the pneumatic relay assembly.
RYRY 29 Hall sensor upper position - Check to make sure the air supply is connected. This error
may be cleared by briefly pushing the Quick-Cal button, which will force the positioner to
use the parameters from the last good calibration. If the positioner still does not operate
replace the pneumatic relay assembly.
RRGG 30 1.23v reference - Bad electronic assembly, replace.
RRGR 31 12-bit A/D reference - Bad electronic assembly, replace.
RRYG 32 Temperature limit - The internal positioner temperature is currently exceeding operational
limits of -40ºF (-40ºC) or 185ºF (85ºC).
RRYY 33 Piezo voltage - Bad electronic assembly, replace.
RRYR 34 Board current high - Check internal wiring and connectors for electrical shorts, if no
shorts bad electronic assembly, replace.
RRRG 35 12-bit D/A reference - Bad electronic assembly, replace.
RRRY 36 EEprom checksum error - The checksum of the internal data has become corrupted.
Cycle power and complete a Quick-Cal if needed. Check internal data to verify correct set-
tings. If the error still occurs, bad electronic assembly, replace.
