Configuration Controls
Refer to Operation Step-By-Step
in the Technical Reference
section of this manual for
detailed information on
available software control of this
model.
Software Configuration Only via USB/Windows or USB-OTG/Android & Agility:
This transmitter drives separate isolated 2-wire loops proportional to sensor inputs
based on differential voltage measurements across the sensors at TB1 (channel 1)
and TB3 (channel 2), or on the differential voltage measure across its 24.9Ω current
shunt resistor for current input path A at TB1 or TB3 (DT236 only). No switches or
potentiometers are used to make adjustment to this transmitter. Its behavior as an
isolated signal amplifier/transducer is determined via programmed variables set
using a temporary USB connection to a host computer or laptop running a Windows-
compatible configuration software program specific to the transmitter model, or a
wired USB-OTG connection to an Android smartphone or tablet running Agility. The
USB software or Agility app provides the framework for digital control of all
configuration and calibration parameters, which are ultimately stored in non-volatile
memory of the unit.
LED Indicators, Red FLT1 & FLT2:
One Red FLT LED per output loop
w/continuously blinking red indicating the output load resistance is too high to drive
its current accurately, or the loop voltage level is too low to drive the loop resistance
at the desired current level. OFF is normal and this LED will only blink one time if
loop power is lost or the loop is opened.
