Note!
These error histories are available (Erroneous Message) at position GVH=037.
OVERTENSION
The tension on the measuring wire
exceeds the upper limit set at
position GVH=162 "OVER TENS.
SET."
Check if the displacer motion is blocked by clogging or
sticking.
To release overtensioning, access position GVH=371
"RELE. OVER TENS."
101
POWER FAILURE
The supply voltage falls below the
allowed value.
Check the power source.
124
RAM FAILURE
CPU RAM failure
ROM ERROR
EEPROM
Consult E+H Service.
132
SIFA ERROR
Error between communication board
and CPU board for digital output.
Replace the CPU board. Consult E+H service.
114
TEMP BELOW
RANGE
Indicates the measured temperature
data is below the fixed range of the
NMT temperature sensor.
TEMP COM OPEN
Indicates an open common line in the
NMT temperature sensor
TEMP COM SHORT
Indicates a shorted common line in
the NMT temperature sensor
TEMP OVER RANGE
Indicates the measured temperature
data is highter than the fixed range of
the NMT temperature sensor.
UNDERTENSION
The tension on the measuring wire
falls below the lower limit set at
position GVH=163 "UNDER TENS.
SET."
Check if the measuring wire is cut or the displacer is lost.
In this case, check the installation of the NMS5.
102
WIRE CALIB ERROR
The deviation of automatic wire
calibration exceeds its set limit.
Check wire and wire drum.
115
Z PHASE NO INPUT
The input of the Z phase signal from
the encoder is not available.
Replace the detector unit. Consult E+H
Service.
106, 112
MPU:XXXX*
(XXXX=text)
CPU error
The error might happen occasionally and might be regis-
tered in GVH=037 (Erroneous Message).
However, it is normally negligible. If it occurs frequently,
then consult E+H Service.
OPE.CODE ERROR
An illegal operation command is
accessed.
If the message occurs frequently, then consult E+H Ser-
vice.
LCD CHECK
Error between LCD (touch control)
unit and CPU boaed for digital
output.
Replace the touch control.
121
GAUGE TEMP.
The temperature inside the gauge
exceeds the limit.
Check if the ambient temperature stays within the limit.
If the application is a high temperature tank, then take
meadures to avoid heat tranfer from the tank to NMS5.
DRIVER ERROR
A motor driver error has occurred
