Flush system (2.10.3.)
Controls an electrically operated flush valve on a pump to divert some pump output back into
the wet well to stir up sediment.
Note
•
If any of the following parameters are set to 0, this feature will not work.
• In Dual-point mode, a flush valve can be set up for each of the three available level inputs
[Sensor Mode (2.1.3.) (Page 163) = Dual-Point Difference or Dual-Point Average].
Single-point mode
Enter the device relay number of the pump with the flush valve. The activation of this pump
relay drives the usage of the flush system. Both Flush Cycles (2.10.3.3.) (Page 217) and
Flush Interval (2.10.3.4.) (Page 217) are based on the operation of this relay, and control any
relay set to Relay Function (2.8.1.4.) (Page 195) = Flush Valve.
Dual-point mode
The indexed relay is the one that controls the flush device. The value is the pump relay that
is watched by the flush system. Enter the pump relay value into the parameter at the flush
relay index.
Example: If you need to watch pump Relay 1 to control a flush valve on Relay 2 (with Relay
index 2 selected), set Flush Pump (2.10.3.2.) (Page 216) = 1.
Relay selector (2.10.3.1.)
Sets the relay index for all parameters applicable to this sub-menu. These parameters only
affect relays set to Relay Function (2.8.1.4.) (Page 195) = Flush Valve.
Flush pump (2.10.3.2.)
Picks the number of the pump relay which triggers the flushing device.

Related Relay Function (2.8.1.4.) (Page 195) = Flush Valve
Enter the device relay number of the pump with the flush valve. The activation of this pump
relay drives the usage of the flush system. Both Flush Interval (2.10.3.4.) (Page 217) and
Flush Cycles (2.10.3.3.) (Page 217) are based on the operation of this relay and controls any
relay set to Relay Function (2.8.1.4.) (Page 195) = Flush Valve.
