Function Description
J1 is used to select the energy direction ( DIRI pin). The three options available are:
P18 should not be left floating and must be connected to one of the options described above.
J2 is only used to select bi-directional energy measurement when connected to P18
These are test points placed next to the digital pins of the SA2002E
Not fitted This is the current sense input ground. If a current transformer is used for current sensing the two
pins of J5 must be connected.
Connects the impulse to VSS. If a stepper motor is connected to JP3 then J6 should be left open.
Analog ground test point (see figure 1)
Positive supply test point (Vdd) (see figure 1)
Used to select the R2, R1 and R0 pins of the SA2002D for the various rated conditions. Refer to table 1 for the
possible settings
Used to select between normal and configure / test modes. For normal operation connect P9 to Vss.
Used to select between 220V and 110V mains systems (See figure 3). Leave open for 220V mains.
Negative supply test point (Vss) (see figure 1)
Used to select fast calibration mode. Connecting P7 to Vdd selects fast calibration mode. For normal operation
P7 must be connected to Vss
