Measurement Conditions

The following information will help you configure your HydroRanger 200 for optimal
performance and reliability.

Response Rate

The response rate of the device influences the measurement reliability. Use the slowest
rate possible with the application requirements.
The response rate is also important to functions connected to the filling or emptying
indicators.

Dimensions [6 relay model]

The dimensions of the vessel, wet well, or reservoir (except empty and span) are only
important if you require volume.
Volume is required to report the level value in terms of volume. The pumped volume
function can also report pumped volume or pump efficiencies.

Failsafe

The failsafe parameters ensure that the devices controlled by the HydroRanger 200
default to an appropriate state when a valid level reading is not available.
• P070 – Failsafe Timer activates if an error condition is detected. Upon expiration of
the timer, relay status defaults to values based on P071.
• P071 – Failsafe Material Level determines the level reading if the Failsafe Timer
expires and the unit is still in an error condition.
• P129 – Relay Failsafe controls the reaction of each relay. See
43 for more information.
If Failsafe Operation activates frequently, see the
