Configuring a Single-Parameter Light Alarm
In this scenario, the Con TROLL PRO monitors a tank using an RDO
®
PRO Probe. The
Con TROLL PRO turns on an aerator when the dissolved oxygen (DO) concentration
falls below 4 mg/L. The light tower shows green when the DO is above 4 mg/L (aerator
off), and yellow when the DO is below 4 mg/L (aerator on).
The RDO PRO Probe is wired as Probe A. Relay 1 is used to implement the control
and display function.
