Wiring Dual Modules to a Mercury Instrument
This section includes the information to wire dual endpoints to a single Mercury Instrument. Installation
requires the correct programming parameters (see Code Settings on page 38).
With Itron 2.4GZ OpenWay remote mount gas modules, utilities can receive corrected and uncorrected
consumption values by installing two modules. The module for corrected reads is attached to the instrument's
pulse output. The module for uncorrected reads is attached to the input switch board. The corrected pulse
output is programmable; the uncorrected pulse output is dependent on the connected meter's drive rate.
Important Some Mercury Instruments have two pulse outputs so the
uncorrected pulse output could be connected to the additional output, but the
connection should be to the input switch board in case the instrument battery
fails. Counts will be collected if the uncorrected pulse is connected to the switch
board since the board is not dependent on battery power.
