Aztec AWT440
Multi-input transmitter
Introduction
—
Aztec AWT440 multi-
input transmitter
The Aztec AWT440 is a universal multi-input
transmitter that uses ABB's Aztec 400 range of
advanced digital sensors for monitoring the key
parameters in municipal and industrial water /
wastewater treatment.
The transmitter has multiple sensor capability that
enables it to control and display information from
up to 4 sensors.
These Commissioning instructions provide
installation and basic operating procedures for the
Aztec AWT440 transmitter.
For information on the sensor, including installation,
commissioning, operation and maintenance
procedures, refer to the specific sensor manual.
