Acknowledge warnings and errors with confirmation button.
The user must ensure a regular change in pressure and thus a proportional output signal change. The
pressure transmitter does not have any diagnostic function for detecting a static signal as a result of an
instrument error.

Description
Internal error (restarting the instrument or resetting to factory settings can provide a solution)
The analogue output controls the alarm signal ≤ 3.6 mA (4 ... 20 mA output signal) or ≥ 11 V
(0 ... 10 V output signal) in accordance with NAMUR43
The switching outputs keep the current switching state (output open or closed)
Instrument temperature exceeded/too low or power supply too low
The analogue output is output. There are limitations with respect to accuracy (temperature influence) and
maximum analogue value (power supply too low)
The switching outputs keep the current switching state (output open or closed)
Sensor defect detected, check whether high overload pressure is present (can be detected as sensor defect), if
necessary, restart instrument or exchange of instrument is needed
The analogue output controls the alarm signal ≤ 3.6 mA (4 ... 20 mA output signal) or ≥ 11 V
(0 ... 10 V output signal) in accordance with NAMUR43
The switching outputs keep the current switching state (output open or closed)
Short-circuit detected at switching output 1 or 2
The switching output affected is inactive so long as the short-circuit is present
