Menu/Enter
The Menu/Enter button moves right in
the menu tree, if there is an item to the right.
If there is no item to the right, the Menu/
Enter button saves the user’s changes
to (non-volatile) memory and exits the menu
tree. This button also allows the user to Zero
the unit from the live display with a (2-second)
long button press. Press Menu/Enter with
a long button press. The word ‘ZERO’ will
flash briefly. The unit is now zeroed and will
then return to the main menu (live pressure
readings).
MAIN MENU SELECTIONS:
A OUT
– Analog Output: Allows user to
choose output signal.
DAMP
– Dampening: Allows user to vary
the response time of the GXLdp output. The
digital display and the analog output are both
updated with the use of the DAMP function.
RECAL
– Recalibration: Allows user to per-
form a field calibration of the zero and span
setting of the GXLdp.
RESET
– Reset: Allows user to reset the
GXLdp to its original factory settings.
ZERO
– Zero: Allows the user to perform a
user zero offset of the GXLdp
SWITC
(Optional) – Switch function: Allows
the user to enable and set one or two
NPN
or
PNP
switch outputs.
A OUT: Analog Output
Analog Output choices are selectable through
the menu.
There are five Analog Outputs to choose from:
4-20 mA, 0-5 Vdc, 0-10 Vdc, 1-5 Vdc, 1-6 Vdc .
a. 4-20 mA is designated by ‘mA’
b. 0-5 Vdc is designated by ‘V0-5’
c. 0-10 Vdc is designated by ‘V0-10’
d. 1-5 Vdc is designated by ‘V1-5’
e. 1-6 Vdc is designated by ‘V1-6’
Please note that 4-20 mA output can be
powered up by a 2-wire or 3-wire Input
Power Supply, while a Voltage output must be
powered by a 3-wire Input Power Supply.
If 4-20 mA output is selected and the SWITCH
function is activated, the unit requires a
3-wire Input Power Supply. The GXLdp can
automatically detect if the input power is a
2-wire or a 3-wire device.
The current Analog Output default can be
seen on the digital display of the main menu
using one of the designations noted above. A
new unit ships with mA (4-20 mA) set as the
default.
