Example: Relay Settings For High and Low Level Indication
With the sensor mounted at 52.5 in. off of the floor looking down. An
indication is needed if the material being monitored is detected closer than 13 in.
or lower than 39 in. from the sensor. Relay number 1 will be used to activate an
alarm.
To program the DCR-WEB for this application, the following modes must be
set:
MODE VALUE

If it is desired that the relays be wired in a fail-safe configuration so that the
relays are closed during normal operation and open if the material is detected
outside of the normal window of operation. This setup also provides for alarm
indication in the event of a loss of power to the sensor.
