The switching characteristics and the hysteresis can

only be programmed via

• the DeviceNet, Profibus, EtherCAT and RS485

interface (

→  [3], [4], [5], [6]).

The thresholds of the setpoints can be adjusted via

• the buttons on the gauge
• the diagnostic port (→  [3])
• the DeviceNet, Profibus, EtherCAT and RS485

interface (

assigned to a setpoint, Low Trip Point only can be
adjusted via the corresponding button on the gauge.

DANGER

DANGER: malfunction
If processes are controlled via the signal output,
keep in mind that by pushing an button the
measurement signal is suppressed and the cor-
responding threshold value is output instead. This
can cause malfunctions.
Push the button only if you are sure that no
damages can arise from a malfunction.
