Warning Description
ATT5 Maximum turndown exceeded
ILOC Menu locked over IO-Link
OL Overpressure, measuring range exceeded > approx. 3.125 % (display flashing)
PAS Prompt for password input
UL Underpressure, below measuring range < approx. 3.125 % (display flashing)
Error Description
ERR 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)
ERR1 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)
ERR2 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)
SC Short circuit detected at switching output 1 or 2
The switching output affected is inactive so long as the short circuit is present
