Badger Meter SRD/SRI Valve Positioners - Manual (Page 60)

TROUBLESHOOTING GUIDE
The components of the positioner are under constant
surveillance by the installed micro controller Errors detected
are displayed in LCD or indicated by the LEDs
Certain conditions (such as “Stroke limitation active”) are
displayed in LCD or indicated by the LEDs as message
Errors Detected During Initialization
After startup or reset, several initialization phases are passed
through which are shown in LCD or in the green LEDs If this
phase stops an error was detected
If after renewed reset
1) the indicator stops at error code,
the device is probably defective and should be sent to the
manufacturer for repair Stating the error code will help the
Repair and Service Dept
1) Execute reset by simultaneous pressing () (–) (+) keys, or by turn-off and restart of
input signal

LED indication for diagnosis, errors:
The following combinations are possible:
After start / reset: (X X X X = error code)
M 1 2 3 4
- X X X X Error detected during Init s. 11.1
Device in normal operation:
M 1 2 3 4
1 -
- - - Cyclical self-test detects errors s. 11.2
- - - - - diagnosis without LED inform s. 11.3
¾ x x x x flashing: message s. 11.4
Errors Detected During Self-Test
During cyclical self-test, certain components of the SRD are
under constant surveillance If necessary, trouble detection
is initiated in the electronics LCD or the red LED; output y1
becomes pressureless (‘fail safe position’)
If after reset
1) the display shows the error again the device
is probably defective and should be sent to manufacturer
for repair
LEDs

RAM / EPROM fault
Actuate “Reset”; send device-
to manufacturer if error re-
appears
1 = LED constant light
1) Execute reset by simultaneous pressing () (–) (+) keys, or by turn-off and restart of
input signal
