4.3.1 Adjusting the Setpoints SP1, SP2
The switching characteristics and the hysteresis can
only be programmed via
• the diagnostic port (→  [3])
• 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 ( →  [3], [4], [5], [6]).
If both a High Trip Point and a Low Trip Point are
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 <SP> button the
measurement signal is suppressed and the cor-
responding threshold value is output instead. This
can cause malfunctions.
Push the <SP> button only if you are sure that no
damages can arise from a malfunction.
