Getting Started
There are three input power options for the SGD-O transmitter:
●
12 Vdc version (standard)
●
24 Vdc (optional)
●
115/230 Vac (optional)
The transmitter power cable is configured to operate the 12 Vdc version
only. In order to use the power cord for 24 Vdc or 115/230 Vac,
modification to the power cord is required. This procedure is described in
the SGD-O installation guide.
Caution
Before setting up or calibrating the gauge, verify that proper input
voltage is being supplied to the transmitter. Also verify the power cord is
configured properly for the required power input.

With the direct access method, users input codes for parameters that need
to be changed or codes to issue commands to the transmitter. This method
allows you to bypass the menu structure and directly access a specific menu
item. In order to use the direct access method, you must know the direct
access code (DAC or the keypad code) for the desired parameter or
command. The parameter DACs have six digits, and the command DACs
have one, two, or three digits. Appendix E provides a list of commonly
used parameter and command DACs.
Note
This manual provides instructions using the direct access method, as
it is a more efficient way to access menu items.
