Flush Systems (P170 to P173) [6 relay model]
Please note that these parameters apply to the HydroRanger 200 6 relay model only.
Use this feature to control an electrically operated flush valve on a pump to divert some
pump output back into the wet well to stir up sediment.
Single Point Mode
Enter the HydroRanger 200 relay number of the pump with the flush valve. The activation
of this pump relay drives the usage of the flush system. Both P172 Flush Interval and P171
Flush Cycles are based on the operation of this relay and control any relay set to P111 =
64, 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 One to control a flush valve on Relay Two you would set
P170[2]=1.
P170 Flush Pump [6 relay model]
Picks the number of the pump relay which triggers the flushing device.
Enter the HydroRanger 200 relay number of the pump with the flush valve. The activation
of this pump relay drives the usage of the flush system. Both P172 Flush Interval [6 relay
model] and P171 Flush Cycles [6 relay model] are based on the operation of this relay and
controls any relay set to P111 = 64, Flush Valve.

• 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
