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.
