Notes:
1) The unit of Mains CT Primary is variable, which is A or mA, and depends on whether the Mains Current Type is Incomer or
Residual .
2) The
Dmd S.R. Time
and
Mthly Energy Log S.R Time
support the following two options:
a. A zero value means that the Self-Read will take place at 00:00 of the first day of each month.
b. A non-zero value means that the Self-Read will take place at a specific time and day based on the formula: Self-Read
Time = (Day x 100 + Hour) where 0 ≤ Hour ≤ 23 and 1 ≤ Day ≤ 28. For example, the value 1512 means that the Self-
Read will take place at 12:00pm on the 15th day of each month.
3) The LED Energy Pulse Modes are listed in the table below:
Value Parameter Value Parameter Value Parameter
0 Disabled 5 SM4 kWh 10 SM9 kWh
1 Mains kWh 6 SM5 kWh 11 SM10 kWh
2 SM1 kWh 7 SM6 kWh 12 SM11 kWh
3 SM2 kWh 8 SM7 kWh 13 SM12 kWh
4 SM3 kWh 9 SM8 kWh
Table 3-10 LED Energy Pulse Modes
4) Since the Mains Current Type can be configured as Incomer or Residual , the Current Alarm settings should be configured
accordingly. When Incomer is selected as the Mains Current Type , the Mains Current Alarm settings would be used for
alarming, and vice versa.
5) The available options for DIx Excitation would depend on the PMC-512-D Model. The 48VDC and -48VDC options are only
available for the hardware that is only equipped with 48VDC DI while the 220VDC, 220VDC, 110VDC and 110VAC options
are available for the 240VDC (max.336VDC) DI.

Notes:
1) If BLTO is set to 0, the Backlight Time Out is disabled, which means that the Backlight will always be on.
2) Auto-Scroll Setup allows users to select which SM and whether Analog Input would be displayed in Auto-Scroll Mode . For
Example, if the PMC-512-D is used for monitoring 9 branch circuits with SM1 to SM9, the remaining three SMs can be
disabled in the Auto-Scroll Mode to prevent unnecessary information from being displayed. The Parameter Categories and
their measurements are listed in the table below, and all of them are Enabled in Auto-Scroll Mode by default. The Parameter
Category Mains Circuit is always shown and cannot be disabled in Auto-Scroll mode.
