Wiring Dual ERT Modules to a Mercury Instrument
This section includes the information to wire dual ERT modules to a single Mercury Instrument. Installation
requires the correct programming parameters (see Code Settings on page 35).
With Itron 100G Datalogging FN remote ERT modules, utilities can receive corrected and uncorrected
consumption values by installing two endpoints. The ERT module for corrected reads is attached to the
corrector's pulse output. The ERT 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 corrector 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.
Dual Remote ERT Modules Mounted on a Mercury Instrument
To install dual 100G Datalogging FN remote ERT modules to a Mercury Instrument Mini-Max
Case Volume Corrector using Mercury Kit 22-1077
1. Place the Mercury Instrument volume corrector in shutdown condition and disconnect all power from the
Mini-Max main board.
2. Remove the battery pack from the volume corrector and set it aside.
3. Remove the four screws from the main board and the board from the enclosure. Set the board aside.
4. Remove the two hex screws from the input switchboard and the switchboard from the enclosure and set it
aside. You will re-install the switchboard later.
Warning The battery pack, main board and switchboard may be damaged if left in the Mercury
Instrument volume corrector while completing this installation.
