100 PSI DEEP: A 100 psi pressure sensor with optional double range span setup. This
option is not produced any more but will be encountered on older installations that are
upgrading firmware. This option will be needed on any firmware upgrade if there is a D after
the firmware revision number and the installed sensor is a 100 PSI sensor, for example
V2.83D. To activate this item press the MENU key and an asterisk will appear in the right
most character in the display. If the item is already activated and the operator wishes to de-
activate the item, press the MENU key and the asterisk will disappear. Press Enter to save
this selection.
100 PSI 16 BIT: A 100 psi sensor is installed with the optional 16 bit A/D converter. Not
modifiable.
RELAYS: The optional relay module is installed. Not modifiable.
A OUT: The optional analog output module is installed. Not modifiable. Note this item will
show an asterisk if the optional Digital Communication Interface Controller is installed. This
is normal.
A IN: The LevelCom 100 is built to take input from an external 4-20 mA transmitter rather
than the typical internal sensor. Not modifiable. This option is obsolete and should not be
encountered.
HORN: The optional piezoelectric horn is installed in the machine. Not modifiable.
S G: The machine is built to read specific gravity. This option uses another sense line
system and must have another output valve built into the pneumatic manifold to function.
This item is configurable through this menu. To activate this item press the MENU key and
an asterisk will appear in the right most character in the display. If the item is already
activated and the operator wishes to de-activate the item, press the MENU key and the
asterisk will disappear. Press Enter to save this selection. It is important to verify that the
specific gravity sense line and valve are present. Activating this item on a standard
LevelCom 100 can lead to problems in normal operation and confusing error messages.
DIFF P: The machine is built to read the pressure in the tank above the liquid. This option
uses another sense line and must have another output valve built into the pneumatic
manifold to function. This item is configurable through this menu. To activate this item press
the MENU key and an asterisk will appear in the right most character in the display. If the
item is already activated and the operator wishes to de-activate the item, press the MENU
key and the asterisk will disappear. Press Enter to save this selection. It is important to
verify that the differential pressure sense line and valve are present. Activating this item on a
standard LevelCom 100 can lead to problems in normal operation and confusing error
messages.
PASSIVE GAUGE: The machine is configured to read a sense line only. It will not apply air
to the sense line. In rare instances two machines are used to read a single sense line. One
machine controls the air to the sense line, and operates normally. The other machine is
