9.1 Troubleshooting

The unit has many self-diagnostic options. 
It monitors itself automatically during operation. Warnings and faults are signalled via IO-Link. If a
process value fails, the other process values are still available.

Additional diagnostic functions are available via IO-Link.

Troubleshooting

Error

Unit faulty / malfunction

21.5 mA

Replace device.

Error

Supply voltage too low.

Off

Check the supply voltage.

Error

Parameter setting outside the valid range.

21.5 mA

Repeat parameter setting.

Error

Error in pressure measurement.

21.5 mA

Check pressure measurement.
Replace device.

Warning

Pressure range exceeded (≥ 105 % VMR*).

OU

Check pressure range.

Warning

Pressure range not reached (≤ -5 %MAW**).

OU

Check pressure range.

*VMR = final value of the measuring range.

**MAW = initial value of the measuring range

In case of a warning the analogue signal is as defined in the parameters [OU].
