Description / Explanation
Recommended Action
Temperature
High
Out of
Specification
Temperature above allowed limit .
Operation outside temperature limit (>80° C, 176° F) may
damage positioner components and violate electrical safety
certification requirements . Stop operating positioner .
Temperature
Low
Out of
Specification
Temperature below allowed limit .
Operation outside temperature limit (<40° C, 40° F) may damage
positioner components and violate electrical safety certification
requirements . Stop operating positioner .
Power Supply
High
Out of
Specification
Power Supply above allowed
limit . 4…20 mA / HART: Operation
above 22 mA Fieldbus / FoxCom:
Operation above 12 mA
Operation outside power supply limit (see PSS for details) may
damage positioner components and violate electrical safety
certification requirements . Stop operating positioner . Ensure that
the maximum power allowed supply is supplied to the unit .
Power Supply
Low
Out of
Specification
Power Supply below allowed limit .
4…20 mA / HART: Operation below
3 .8 mA
Fieldbus / FoxCom: Operation below
9 mA
Operation below power supply limit (see PSS for details) may
cause the positioner to go into failsafe . The communication to
the control system might be disturbed . Ensure that the minimum
power supply is supplied to the unit .
Air Supply
Pressure Alarm
Service /
Maintenance
Required
The Air Supply Pressure falls below
the configured Lower Limit .
Check if the adequate supply pressure is applied .
Output Pressure
Alarm
Service /
Maintenance
Required
The positioner cannot regulate the
Output Pressure .
Check pneumatics . Check tubing to the actuator . Check for
leakages caused by the diaphragm .
Drag Pointer
for Maximum
Temperature
—
Shows the maximum measured
temperature during operation .
Shows the exact value of the maximum temperature ever
measured to ensure that the High Temperature limits
(>80° C, 176° F) are not reached .
Drag Pointer
for Minimum
Temperature
—
Shows the minimum measured
temperature during operation .
Shows the exact value of the minimum temperature limit ever
measured to ensure that the Low Temperature limits
(<40° C, 40° F) are not reached .
Partial Stroke
Testing
—
The Partial Stroke Testings allows
to evaluate if an Emergency
Shutdown Device (ESD) will
operate in case of a safety
shutdown .
The Partial Stroke Test can be found under the Configuration/
Partial Stroke . This is where the Test can be configured and
activated . The Testing Status shows the evaluation of the test .
Testing Status
Good
Not Done
A Partial Stroke Test has not been executed yet .
Good
Running
Test has been started and is in progress .
Local Operation Restricted
Test is restricted . Either the valve is in control or the valve is not
fully open (100%) .
Good
OK
Test performed OK . The ESD capabilities have been tested and
showed that the valve is not stuck . The valve would move if a
safety system would close the valve .
Failure
Error
Test showed Error . The ESD capabilities cannot be guaranteed .
The valve is stuck and cannot move . The valve needs to be
inspected immediately!
