By now the parameter settings are completed. Pressing “F” and “V/A” simultaneously will
exit system parameter settings mode and return to the metering data mode.
3.4 I/O Parameter Settings
For meters with I/O module, under system parameter settings mode, hold “F” key for 3 seconds to enter I/O settings mode. In I/O settings mode, key functions are the same as the
one in system parameter settings mode. “F” key is used to increase value by 1 for the flashing digit. “V/A” key is used to confirm the flashing digit and move the cursor. At the last
digit of the parameter, pressing “V/A” key will confirm and go to the next screen. On any
screen, pressing “F” and “V/A” simultaneously will exit I/O parameter settings mode and
return to the system parameter settings mode.
I/O module has two types: AO type and RO type.
For AO type module, it offers two channel AO, which can be selected as voltage or current
type. AO parameter can be voltage, current and power. AO upper and lower limits include
"sign" and "percentage" digit. The sign digit has three options: represents(+), represents(-), represents(±). The percentage digit's range is "0.00-1.00", representing "0%100%".
When AO parameter is set as voltage, the upper and lower limit setting is "0%-100%". When
AO parameter is set as current or power, there are four modes:“0% - +100%”;“0% - -100%”;“100 - +100%”and“0% - ±100%.
Note:
1. there is no "sign" digit when AO is set as voltage. "sign" digit is invisible when percentage is 0.
2. For limit setting,1.00 is 100%,0.00 is 0%,0.25 is 25%.
