6 Commissioning/start-up

6.9.1

Setting the scaling start value (Sc.Lo)

Example:
The device has a measuring range from -50 to +150 °C.
The device output signal is 0 to 20 mA.

How to proceed:

TIP!
The output signal can only be scaled on devices with analog output.

Setting range:

Measuring range

Factory-setting:

Measuring range start

Objective:

The range from 0 to 100 °C (customer scaling) is to be displayed on the out-
put side by 0 to 20 mA.

Setting:

Scaling start value (Sc.Lo) = 0
Scaling end value (Sc.Hi) = 100

Result:

At a temperature below 0 °C, the device indicates an error (measuring
range gone below) and provides the respective error signal (0 mA) on the
analog output.
At a temperature of 0 °C, the device provides 0 mA on the analog output.
At a temperature of 100 °C, the device provides 20 mA on the analog out-
put.
At a temperature exceeding 100 °C, the device indicates an error (measur-
ing range exceeded) and provides the respective error signal (22 mA) on
the analog output.
