Colors identifier indication and resolution
YGRY 23 Analog output span too small - The span must be calibrated to a range greater than 3.0 mA. 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.
R - - - Any sequence starting with a red light indicates that there is an operational problem with the unit.
RRYY 25 Piezo voltage - (bad electronic assembly - replace.)
RYYR 26 Relay not operating – Most Likely the Air supply is disconnected. Could also be due to a bad pneumatic relay, failed
electronics, or a loose or bad connector from the electronics to the relay.
RYRY 27 Relay failed – Could be due to a bad pneumatic relay, failed electronics, or a loose or bad connector from the
electronics to the relay.
RGRR 28 Position Deviation – Indicates that he position has exceeded a fixed 20% error between command and position
for a period of time 5 times longer than the recorded stroke time. This error is usually seen when the positioner is
first mounted and powered up before a stroke calibration has been done. If the positioner is properly calibrated,
the air supply is correct, and the linkage is properly adjusted this error normally indicates that there is a mechanical
problem in the positioner, actuator, or valve that is preventing the valve from stroking properly. If a regulated air
supply connected to the actuator properly strokes the valve this indicates a bad positioner and should be replaced
if a calibration does not clear the error.
