Physical Description (Personality Modules)
The CENTRON Personality Modules snap into the meter register mounting brackets to ease
installation of the board.
The LCD module is connected to the metrology board using the board-to-board connector.
The following information is sent to the LCD module from the metrology board:
 Line voltage
 Reference voltage
 Energy flow direction
 Energy pulse data
 Line frequency
A connector is located at the 12 o'clock position behind the LCD for resetting the energy
register. This is done using the ZRO-C2A Resetter.

Registers
Kilowatt Hours
The modules display energy in increments of whole values of kWh. Standard operation for
all modules is to add forward and reverse energy flow, thus providing uni-directional
operation. This feature is factory programmable and will only measure delivered energy. At
the time of order, the energy-only module can be selected to have a detent register.
Programmed at the factory, this feature will cease registration while the meter is inverted, or
power flow is otherwise reversed. The module can also be selected to have a net register.
This feature is factory programmable and will measure delivered minus received energy.
