Outputs Menu (Relay Outputs - Set Point 1) - Seko K500 TB Manuel D'installation

C1) Probe typology
This functional allows the user to select whether to use the Turbidity probe or the Suspended
Solids probe.
C2) Unit of Measure
This function allows the user to select the unit of measure from amongst NTU, FTU, g/l and mg/l.
Based on the type of probe connected, certain units of measure will be disabled. This will be
indicated on the display during the configuration phase:
C3) Range
This function allows for the selection of the instrument's operating range. Based on the model of
the connected probe, the available ranges include:
The correlation between the measurement probe, the unit of measure and the range of
measurement is indicated in section 2.2.1.

The programming parameters of Set Point 1 determine the functioning logic of a Relay 1. The logic
of Relay 1 can be programmed in the following manners:
D1) Threshold
By setting the Set Point as Threshold, the Relay can be programmed to ON (relay activation) or
OFF (relay deactivation). The free programming of these two values allows the user to create a
hysteresis suitable for any type of application.
By programming an ON value higher than the OFF value (fig. 12.a), an UPWARD threshold
functionality can be obtained: (when the value exceeds the value of ON, the relay is enabled and
remains active until the value descends below the value of OFF).
