Time Out

Alarm

Indicates that functions in the

firmware took longer than expected.

This can be caused when intermittent

operation occurs when connecting

power.

Remove power and then reconnect to

clear this alarm. If the alarm persists

replace the main circuit board.

Ram Check-

sum Alarm

Indicates the check sum of the internal

data was not updated correctly. This

may affect the function of the posi-

tioner in various ways or not at all.

Error may clear with time. If error

persists, cycle power and complete a

QUICK-CAL. If the error still persists,

replace the main circuit board.

Electronic In-

ability to Fail

Safe Warning

Indicates that the peizo may be dam-

aged. This may prevent the proper

failure position upon loss of signal/

power. This condition may occur

briefly on an air-to-close valve that is

held for long periods of time in the

closed position, or and air-to-open

valve held in the open position.

If alarm persists for more than 30

minutes, the piezo assembly is

damaged and should be replaced.

Supply Pres-

sure Low

Alarm

Indicates that the supply pressure is

below the user set alarm limit. Low

supply pressure can cause poor valve

response or positioner failure. The

minimum recommended supply pres-

sure is 30 PSI (2.1 bar) for proper

operation. The unit will fail at less

than approximately 17 PSI (1.2 bars).

Low supply pressure indicates can

also be caused by pneumatic leak.

Regulate the supply pressure at the

positioner above 30 PSI (2.1 bar).

Recalibrate pressure sensors. Ensure

system air/gas supply is adequate.

Repair kinked supply tubing. Check the

pressure sensor board connections

and replace pressure sensor board if

necessary. Check for pneumatic leaks

in the actuator and actuator tubing.

Warning

Indicates the positioner has deter-

above the user set warning limit.

Regulate the supply pressure at

the positioner below the maximum

limit recommended for your actuator.

Recalibrate pressure sensors. Check

the pressure sensor board connec-

tions. Replace pressure sensor board

if necessary.

Warning

Indicates the supply pressure is be-

low the user set warning limit. Lows

supply pressure can cause poor valve

response or positioner failure. The

minimum recommended supply pres-

sure is 30 PSI (2.1 bar) for proper

operation. The unit will fail at less

than approximately 17 PSI (1.2 bars).

Low supply pressure indicates can

also be caused by pneumatic leak.

Regulate the supply pressure at the

Warning

Indicates the internal pressure sensor

the sensor connection has failed.

Port 1 Range

Small Warn-

ing

Indicates that during a pressure sen-

sor calibration, the range of applied

pressures to Port 1 was too small for

optimum performance.

Adjust the supply pressure to a higher

value so the positioner can properly

span the sensors, then recalibrate.

Briefly push the QUICK-CAL button

to acknowledge this condition and

the positioner will operate using the

current short stroke calibration values,

if valid.
