Error Code
-49.5 ºC
Indication of shorted element in NMT
temperature sensor
Check GVH=450 thru GVH=459 to see element.
358.0 ºC
Element is not enabled, or not
installed in NMT temperature sensor .
Check GVH=482 Total number of elements
359.0 ºC
Indication of open element in NMT
temperature sensor
Check GVH=450 thru GVH=459 to see element.
ADC/SENSOR ERROR
The signal from the A/D converter is
out of range.
Consult E+H Service.
107
ADJ. XXXCOUNTER
(X=A, I, Z or combina-
tion)
Error of level data check by A, I, and/
or Z phase encoder.
If the message appears frequently, then consult E+H Ser-
vice.
A PHASE NO INPUT
The input of the A phase signal from
the encoder is not available.
Replace the detector unit. Consult E+H Service.
122
BELOWBOT. POINT
Indicates NMS displacer position is
below lowest of NMT temperature
sensor.
DEVICE ERROR: DEV
1 (or 2)
The HART device 1 (or 2) gives an
error signal.
Check the HART device 1 (or 2) .
130, 131
DEVICE ERROR: NMT
NMT 53x gives an error signal.
Check the connection of NMT 53x. Check the register of
the temeperature sensor at position GVH=362 "CONNEC-
TION NMT."
250
DEVICE ERROR: NMT
NMT 53x temperature sensor is not
available.
Check NMT 53x. Error messages are available in NMT
53x manual.
233
DEVICE ERROR: NRF
NRF 560 gives an error signal.
Check NRF 560. Error messages are available in NRF 560
manual.
240
DISPL CALIB ERROR
The deviation of automatic weight
calibration exceeds its set limit.
Check build-up or deposit on the displacer.
120
ELEM 0 RANGE OVER Indicates the reference resistance ele-
ment (ºC) on NMT electronics is out-
of- tolerance.
IMPOSSIBILITY
Operation is impossible because there
is no weight table.
LOCAL ERROR: DEV1
(or 2)
NMS5 cannot access the local HART
device 1 (or 2).
Check the connection of the HART
device to NMS5.
Check the registration of the device(s) in matrix group
G5/6.
232
LOCAL ERROR: NMT
The signal from NMT 53x tempera-
ture sensor is not available.
Check the connection of NMT 53x. Check the register of
the temperature sensor at position GVH=362 "CONNEC-
TION NMT."
111
LOCAL ERROR: NRF
NMS5 cannot access NRF 560.
Check the connection of NRF 560 and register of the tank
side monitor at position GVH=361 "CONNECTION NRF."
113
MINTENANCE
GVH157 Service Mode = ON
Set GVH157 = OFF
