Relay Controlled By Communications; Tracking Pump Usage; Rake (Screen) Control - Siemens HydroRanger 200 HMI Operating Instructions Manual

7.9.4.10

Relay controlled by communications

A relay can be controlled directly by a remote system through communications. No other
control schemes can then be used with a relay configured this way. Communications can be
used to force status of some control relays, such as pumps.

Rake (screen) control

Rakes or screens are mounted on the inflow channel of the wastewater treatment plant to
prevent debris from clogging the equipment. When material builds up on the screen, a level
differential is created, and the water level is higher in front of the screen than behind it. When
this differential reaches the programmed setpoint, the device activates a relay to operate
mechanical rakes that clean the screen and ensure a steady flow.
