Selection No selection. The user is free to edit the values.
Factory setting Upper measuring limit or as per order specifications.
GTL Pressure applied for 4mA (LRV)
Navigation EF → I → GTL
Description The pressure value present is automatically adopted for the 4 mA current signal.
Parameter for which the current range can be assigned to any section of the nominal
range. This occurs by assigning the pressure lower range value to the lower measuring
current and the pressure upper range value to the upper measuring current.
The pressure lower range value and upper range value can be configured independently of
one another so the pressure measuring span does not remain constant.
The LRV and URV pressure measuring span can be edited over the entire sensor range.
An invalid TD value is indicated by diagnostic message S510. An invalid position offset is
indicated by diagnostic message C431.
The editing operation cannot result in the device being operated outside the minimum and
maximum sensor limits.
If the entry is not OK, it is rejected, the message "FAIL" appears on the local display and the
last valid value before the change is used again.
The measured value currently present is accepted as the value for 4mA anywhere within
the measuring range.
There is a parallel shift of the sensor characteristic so that the pressure present becomes
the zero value.
