7.1
Initial Settings
All of the initial settings are required for NMS5 in most case. However, depending on NMS5 specification,
some settings may not be required. Set Access code 51 at GVH039 before applying the initial settings.
7.1.1
System Calendar/Clock (GVH193 to 197)
Calendar/Clock values are set at factory (Japan Standard Time) prior to delivery. Change the data to reflect
local time.
7.1.2
Density Values (GVH005 to 007)
Caution!
Always set GVH=005 Upper Density for actual density data, in LPG and any application where the actual den-
sity is 0.7000 g/ml or less. failure to set this data may result in level gauge malfunction.
Density values for 3 liquid phases are set to 1.000 g/ml prior to delivery. Change the data to reflect actual den-
sity values. For tanks with only one liquid phase, set Upper Density. For tanks with 2 or 3 clear phases, set
Middle and Bottom densities too. Note: minimum difference between phase
settings should be at least 0.100 g/ml. *GVH005£GVH006£GVH007
Example:
•
GVH005 Upper Density: 0.758
•
GVH006 Middle Density: 0.880
•
GVH007 Density Bottom: 1.000
7.1.3
Tank Height (GVH140)
Tank height value is set to default value at factory prior to delivery. Tank height is the reference height, usually
a gauging hatch on the tank that is used during manual level measurements. Change GVH140 to equal the
reference height.
Note!
GVH141 "Dip Point Offset" will
automatically
change to reflect the difference in height between the reference
height and the NMS5 reference position.
