Instruments
The plug-in connections on the Power Supply Board are called MOD 1,
MOD 2, MOD 3 and MOD 4, and are, respectively, the signal counterparts for output
1, output 2, output 3 and output 4, on the Controllers I/O terminals shown on figure 3.
The plug-in connection for the communication module is located on the CPU Board
and have no denomination. Any optional module should always be installed with the
component side facing the instrument display, as illustrated on figure 35.
DISPLAY
Outputs 1 and 2 as analog outputs (optional module code: MSAN-20)
Whenever output 1 is required to be the analog output (4 to 20mA, 1 to 5V or 0
to 10V) the optional module is plugged in the connection called MOD 1. In case an
additional analog output is required, a second module is plugged in the connection
called MOD 2.
The analog output optional module is provided with two locations for the
installation of jumpers: J1 and J2, as illustrated on figure 36.

To configure the analog output optional module for control outputs 4 to 20mA,
1 to 5V or 0 to 10V just install the jumper as specified on table 3.
