In addition, you may configure any relay independently and program it to
activate pumps or control valves.
As process alarms, alarm logic (high or low activation or USP*) and
deadband are user-programmable. Customer-defined failsafe operation is
supported as a programmable menu function to allow all relays to be
energized or not energized as a default condition upon powering the
transmitter. You may program the USP* alarm to activate when the
conductivity is within a user-selectable percentage of the limit. USP*
alarming is available only when a contacting conductivity measurement
board is installed.
