Badger Meter SRD/SRI Valve Positioners - Manual (Page 68)

The SRD991 Status Overview screen was modified to be simpler with
a focus on the most important . This concept still includes status bits
in green (√) = good and red (X) = alarm, and in addition colored tabs,
highlighting the different areas where the alarm is active .

Valve Stuck
High Friction
Alarm
Control Diff OOL Fault / Device
Failure
This Alarm indicates a critical
state for the operation of the
device.
The friction of the Stem
packing has increased to a
level that the valve movement
is blocked and causes a
remaining control deviation .
The valve needs to be
inspected immediately .
Pneumatic
Failure
Supply- Pressure
Alarm
Control Diff OOL Fault / Device
Failure
This Alarm indicates a critical
state for the operation of the
device.
The supply pressure has
failed and caused a remaining
control deviation .
Check if the filters are
obstructed .
Restore the supply pressure
and check the control
behavior .
Actuator Leakage
/ Pneumatic
Failure
Output- Pressure
Alarm
Control Diff OOL Fault / Device
Failure
This Alarm indicates a critical
state for the operation of the
device.
The supply pressure can
be measured, but the
valve cannot be moved .
The positioner identifies a
remaining control deviation .
Check the pneumatics and the
piping to the actuator .
Failsafe
Power Supply
Low
—
Fault / Device
Failure
This Alarm indicates a critical
state for the operation of the
device.
The power supply is below the
specified range and causes the
valve to go in failsafe .
Power Supply below allowed
limit .
4…20 mA / HART:
Operation below 3 .6 mA
Fieldbus / FoxCom: Operation
below 9 mA
Correct the Power Supply to
the specified minimum limits .
4…20 mA / HART:
Minimum operating value
to turn off the alarm is > 3 .8
mA . The minimum specified
current is 4 mA .
Fieldbus:
Minimum operating value:
≈10 .5 mA ± 0 .5 mA (voltage
range 9…2V DC)
FoxCom:
Minimum operating value: ≈ 9
mA at 24V DC .
