Average or Differential [MR 200 only]

For differential or average operation dual-point MultiRanger, set P001 to 4 (differential) or
5 (average) and connect two transducers of the same type.
All the relevant parameters are then indexed by the correct number:

Measurement Conditions

The following information will help you configure your MultiRanger 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 [MR 200 only]

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 MultiRanger 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
44 for more information.
If Failsafe Operation activates frequently, see the
7ML19981FB05 MultiRanger 100/200 – INSTRUCTION MANUAL
