Installation and Operation
2.5
FRONT SIDE OF THE PCB – DETAILED DESCRIPTION
2.5.1
Shunts for Gain and FC selection (J11–J15)
Positions for both logic “high” and logic “low” are here for all gains and frequency con-
stant selections. The logic “high” positions are labeled J1H, and the “low” positions are
labeled J1L, as an example for Jumper 1. Do not short both the “high” and the “low”
positions for any of the jumpers.
2.5.2
Calibration Jumpers (J1–J10)
Calibration resistors for each of these jumper locations are located directly beneath the
associated jumper. When a shorting resistor or a jumper is in place, the associated
calibration resistor is shortened and bypassed.
2.5.3
Output Connections for Mechanical Counter and Calibration
(JP5-JP7)
JP5 and JP6 are the differential output drive for the mechanical counter.
JP7 is the calibration or microcontroller output that is connected to HF OUT on the
MCP3907 devices. An LED is supplied to assist in any optical calibration schemes.
2.5.4
Connection to Current Sensing Element (JP1, JP2)
These two connections lead directly through LRC filtering into Channel 0 of the
MCP3907 device. The schematic in Appendix A. “Schematic and Layouts” uses a
low cost shunt as current sensing element. The shunt resistance should be placed in
parallel with these two connections, between JP1 and JP2.
2.5.5
Connection to Voltage or Phase Line and Ground Reference
Point (JP3, JP4)
These two connections feed the DC power supply circuitry described in
Section 2.6.2 “DC Power Supply (C17, C16, U2, C18, D2)” . JP4 is connected to the
ground of the PCB, and JP3 to the high side of the DC power supply circuitry. JP3 is
also connected to the resistor divider that feeds the analog input of Channel 1 of the
MCP3907 device. This is the measuring voltage channel, connected to the differential
input in a single-ended fashion. See Section A.3 “Board – Schematic” for further
details.
