SETTING UP THE PM2005M/P MODULE

JUMPER DESCRIPTION

Power Supply Jumpers

The power supply jumpers are used to disconnect the on-

board power supply, allowing the metering section of the circuit

to be powered from an external power supply if required.

Voltage Selection Jumpers

These jumpers are used to select between 115V and 230V

operation. When closed the jumpers will half the series

resistance in the voltage divider to the voltage sense inputs.

Connects VDD to the metering circuitry.

Connects VSS to the metering circuitry.

GND connection point.

Connection point between the power supply

GND (N) and the SA2005 GND

Module Setup Jumpers

Setup for use with the SA2005M

Please note that only one jumper

should be closed at any one time. Closing more than one

jumper may short circuit the power supply.

The following jumpers (S1 and S9) are used to set the various

dividing ratios, resolution and summing modes.

Jumpers S1 to S3 set the rated conditions dividing ratio (pin

RA of the SA2005M).

Jumpers S4 to S6 set the calibration LED resolution (dividing

ratio) as well as the summing mode (pin RE of the SA2005M).

Please note that only one jumper should be closed at any

one time. Closing more than one jumper may short circuit

the power supply.

Jumpers S7 to S9 sets the dividing ratio (counter resolution,

pin IM of the SA2005M) for the SA2005M’s motor drive output.

Please note that only one jumper should be closed at any

one time. Closing more than one jumper may short circuit

the power supply.

Set-up for use with the SA2005P

Jumpers S1 to S9 must be removed (open), so as not to

influence the functionality of the IIC bus operation. Jumper S10

may be used on certain IIC EEPROMS to protect the data

written to the EEPROM. This jumper must be opened when

programming the EEPROM.
