SETUP OF THE PM4100APD AS AN
ENERGY/POWER EVALUATION BOARD
The PM4100APD evaluation module comes with several
jumper selections, which allows the user to setup the module to
work for any of the devices mentioned. Tables 2 to 8 describe
the various jumper options. These tables should be used in
conjunction with figure 9, as well as the accompanying software
on disk (PM4100.exe) which will make it easier to locate the
jumper in question.
External connectors
The PM4100APD module connects directly to live and neutral
by means of a screw terminal (SCK1), and the current sensing
element is connected to CON2 as is shown in figures 5 and 6.
Connection diagram for CON3 and CON6 is shown in figures 7
and 8.
Programming the SA2002P must be done via an external
programmer/opto-isolator that connects to CON 3. There is
such a module available on request from SAMES, or a module
can be build as per information supplied in Figure 7.
Table 1 lists all the connectors available on the module.
