Indication and Resolution

RGYR

Loss of supply pressure The Positioner has determined that the supply pressure is below

15 psi. Check the supply pressure and if OK check the pressure sensor board connections

and replace pressure sensor board if necessary. Minimum recommended supply pressure is

30 psi for proper operation.

RYGG

Factory reset condition Recalibrate.

RYYY

Pilot relay non-motion alert Check to make sure the air supply is connected. Also check

the internal wiring harnesses for good connections. This error may be cleared by briefly

pushing the RE-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

Watchdog timer timeout (also listed as internal voltage reference) This is often caused

when intermittent operation occurs when connecting power. Remove power and then recon-

nect to clear. If problem persists it is a bad electronic assembly, replace.

RRYG

Internal temperature alert The internal positioner temperature is currently exceeding

operational limits of -40ºF (-40ºC) or 185ºF (85ºC).

RRYY

Piezo voltage error Bad electronic assembly, replace.

RRYR

Internal voltage reference error Indicates that the circuit board is drawing too much

power. Check internal wiring and connectors for electrical shorts—if no shorts are present,

replace the electronic assembly.

RRRG

Loss of Inter-PCB Communications Cycle power to restart.

RRRY

NV RAM checksum error The checksum of the internal data was not updated correctly.

Cycle power and complete a RE-CAL if error persists. Check internal data to verify correct

settings. If the error still occurs, replace the electronic assembly.

7.10 Version Number Checking

The version number of the embedded code may be checked at any time except during a calibration
by holding down the up arrow Jog button ( ). This will not alter the operation of the unit other than
to change the blink sequence to three blinks indicating the major version number. Holding the down
arrow Jog button ( ) will give the minor version number without affecting operation. The version
codes are interpreted by adding up the numbers assigned according to the following table:

Color

First blink value

Second blink value

Third blink value

Green

Yellow

Red
