Display and Outputs
|
The
LCD display shows the type of sensor that is being monitored, the data
reading and the
|
engineering units. The display also indicates if
either relay has been triggered since last
|
reset, which relay was triggered and whether the maximum
or minimum limit was exceeded.
|
Two separate relays are provided for controlling all types of
external devices including
|
samplers, alarms,
mixers, pumps, control valves, floodgates and telemetry systems. Each
|
relay is independently programmable to trigger on maximum
and/or minimum levels in one
|
of three
different modes.
