Proservo NMS5
Diagnostic : BELOW BOT. POINT
(FLASHING ON ANY
DISPLAY)
SW v 4.20 or Later ?
No
Adjust G4V8H6 from
0 -500 mm.
This will create an offset for
temperature elements.
Diagnostic : DEVICE ERROR: DEV1 (2)
(FLASHING ON ANY
DISPLAY)
Refer to HART device
Operating Manual
Diagnostic : DEVICE ERROR: NMT
(FLASHING ON ANY
DISPLAY)
Check G4V8H0 for NMT
Diagnostics codes, refer to
NMT Operating Manual.
Diagnostic : DEVICE ERROR : NRF
(FLASHING ON ANY
DISPLAY)
Refer to NRF Operating
Manual.
Endress+Hauser
Meaning:
Shorted element in NMT
temperature
Yes
Set G4V9H8 = ON
Note!:
If displacer position gose
lower than (Elem 0 position
+ G4V8H6), BELOW BOT.
POINT will display.
Meaning:
An error has occurred at the
HART device.
Meaning:
An error has occurred at the
NMT temperature sensor.
Meaning:
An error has occurred at the
NRF tank side indicator.
Diagnostic : DISPL CALIB ERROR
(FLASHING ON ANY
DISPLAY)
Yes
Buildup on displacer ?
No
Increase G1V8H5, or
adjust Hall sensors and
recalibrate.
Diagnostic : ELEM 0 RANGE OVER
(FLASHING ON ANY
DISPLAY)
Yes
G4V4H7 = 0.0 C ?
No
Yes
G4V4H7 <+/-9.9 C ?
No
Record Temperature matrix
data, exchange temperature
electronics.
Diagnostic : IMPOSSIBILITY
IMPOSSIBILITY
OPERATION
Adjust Hall sensors and
make weight table.
10 Diagnosis and Troubleshooting
Meaning:
Measured weight of the
displacer exceeds
allowable limit:
G1V8H4 >=G1V8H5
Clean displacer, wire, wire
drum, adjust Hall sensors,
recalibrate
Meaning:
The A-phase signal output
from the encoder, or input
to CPU. is abnormal.
20 outputs = 360 degrees.
Loose connector J3 behind
NMS terminal block. Check
connector.
At G4V7H1 select element
0, then at G4V4H7.
Repeat for all elements.
Meaning:
Operation impossible
because a valid weight table
does not exist.
