Installation Guide

Connecting to a Honeywell Mini-AT, Mini-Max, or EC-AT
With Itron remote modules, utilities can receive corrected and uncorrected consumption values
by installing two modules. The module for corrected reads is attached to the corrector's pulse
output. The module for uncorrected reads is attached to the input switch board. The corrected
pulse output is programmable, and the uncorrected pulse output is dependent on the connected
meter's drive rate.
Important! Some Honeywell 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.
This installation procedure requires a Honeywell mounting kit (Honeywell part number 22-1077).
The illustrations show connection to a Honeywell Mini-AT. Connection to the Honeywell EC-AT
and Mini-AT are similar to these instructions. See Honeywell product documentation for more
information.
1. Connect the corrected module wires to TB1 on the Mini-Max board following the Corrected module
connection information. Use Honeywell upgrade kit 40-2678-1 to provide the second pulse output channel
for the uncorrected endpoint.
2. Insert the remote module cable into the instrument's compression connector.
3. Strip one inch of the outer insulation from the cable.
Warning! Keep wires away from the rotating magnetic spindle in the
Honeywell Instrument.
