sames
For module calibration use Channel Sel. (below) to switch to
one of the two channel permanently. Calibrate the channel and
switch to the next channel. Calibrate the channel and set
Channel Sel to automatic for normal meter operation. This is
equal to the SA9607P’s Kc parameter, which is used for
channel balance.
Channel Sel.
The channel select parameter selects the source for energy
metering. (SA9607P’s CS parameter). The options are ‘0’ for
automatic, ‘1’ for channel 1 and ‘2’ for channel 2.
Earth Leak
The modules earth leakage compensation value is set up with
this parameter. (SA9607P’s Ne parameter). The options are ‘0’
for a factor of 0.15, ‘1’ for a factor of 0.076 and ‘2’ for a factor of
0.032.
LIST MEMORY
The memory map, as calculated from the settings in the
program, is listed by pressing “l”. It does not show the content
of the EEPROM.
WRITE TO EEPROM
Pressing “w” writes to the EEPROM. The EEPROM on the
PM9607AP module will be updated with settings specified by
the program.
DEVICE RELOAD TRIGGER
Pressing “t” triggers a reload. The SA9607P is triggered and
reloads the parameters from the EEPROM. The SA9607P will
reload the parameters every 1132 seconds.
PCB DESIGN
The module represents a Class 1 meter and is designed to
demonstrate the functionality and performance of both the
SA9607M and the SA9607P single phase metering circuits.
The SA9607M requires external settings and gain adjustment.
The SA9607P allows for complete digital calibration without
any external adjustments. The board can be configured for
either of the two ICs by means of jumper settings.
The module is a demonstration unit as well as a reference point
for the meter manufacturer. All the digital pins of the device
have at least one test point. Jumpers isolate LED’s and
counters from the device
GROUND PLANE
The groundplane, which is connected to neutral, protects the
device from external noise and is used to connect the power
supply bypass capacitors C1 and C2. On the current input
resistors and the CT termination resistor loops are introduced
to cancel out the signal induced by the transformers magnetic
field.
The 5V supply is de-coupled and routed directly to the power
pins of the IC. P2 is connected with a separate track to the VSS
pin of the SA9607.
READ FROM EEPROM
The contents of the EEPROM is displayed by pressing “r”.
QUIT THE PROGRAM
The program is exited by pressing “q”.
