Message
-49.5 ºC Indication of shorted element in NMT
temperature sensor
358.0 ºC Element is not enabled, or not installed
in NMT temperature sensor .
359.0 ºC Indication of open element in NMT
temperature sensor
ADC/SENSOR ERROR The signal from the A/D converter is
out of range.
ADJ. XXXCOUNTER Error of level data check by A, I, and/or
(X=A, I, Z or Z phase encoder.
combination)
A PHASE NO INPUT The input of the A phase signal from
the encoder is not available.
BELOWBOT. POINT Indicates NMS displacer position is
below lowest of NMT temperature
sensor.
DEVICE ERROR: DEV 1 The HART device 1 (or 2) gives an error
(or 2) signal.
DEVICE ERROR: NMT NMT53x gives an error signal.
DEVICE ERROR: NMT NMT53x temperature sensor is not
available.
DEVICE ERROR: NRF NRF560 gives an error signal.
DISPL CALIB ERROR The deviation of automatic weight
calibration exceeds its set limit.
ELEM 0 RANGE OVER Indicates the reference resistance
element (ºC) on NMT electronics is out-
of- tolerance.
IMPOSSIBILITY Operation is impossible because there
is no weight table.
LOCAL ERROR: DEV1 NMS5 cannot access the local HART
(or 2) device 1 (or 2).
LOCAL ERROR: NMT The signal from NMT53x temperature
sensor is not available.
LOCAL ERROR: NRF NMS5 cannot access NRF 560.
MINTENANCE GVH157 Service Mode = ON
MEM. ERROR Defect in the memory that is specially
used for custody transfer sealing.
MPU RESET Power to the CPU module fell below
minimum value.
MPU: START ACT* Power to NMS5 was turned OFF/ON.
OVERTENSION The tension on the measuring wire
exceeds the upper limit set at
position GVH162 "OVER TENS. SET."
POWER FAILURE The supply voltage falls below the
allowed value.

11.2 Error and status messages

Cause Remedy
Check GVH450 through GVH459 to see element.
Check GVH482 Total number of elements
Check GVH450 through GVH459 to see element.
Consult E+H Service.
If the message appears frequently, then consult E+H Service.
Replace the detector unit. Consult E+H Service.
Check the HART device 1 (or 2) .
Check the connection of NMT53x. Check the register of the
temperature sensor at position GVH362 "CONNECTION
NMT."
Check NMT53x. Error messages are available in NMT53x
manual.
Check NRF560. Error messages are available in NRF560
manual.
Check build-up or deposit on the displacer.
Check the connection of the HART device to NMS5. Check
the registration of the device(s) in matrix group G5/6.
Check the connection of NMT53x. Check the register of the
temperature sensor at position GVH362 "CONNECTION
NMT."
Check the connection of NRF560 and register of the tank
side monitor at position GVH361 "CONNECTION NRF."
Set GVH157 = OFF
Replace the CPU board. Consult E+H Service.
If the message occurs frequently, then consult E+H
Service.
Check if the displacer motion is blocked by clogging or
sticking.
To release overtensioning, access position GVH371 "RELE.
OVER TENS."
Check the power source.
