Selection of units
After choosing the input signal type you can choose which process units should
be displayed in text line 2 (see table). By selection of temperature input the
process value is always displayed in Celsius or Fahrenheit. This is selected in
the menu point after selection of temperature input.
Safety readback
When the device is delivered with default configuration, the SIL function is
disabled. The safety readback function (loop surveillance) can be selected in
the menu O.RANGE, thus enabling the device to run in SIL mode. In order
to enable the SIL functionality, the menu item S4...20 mA must be selected.
Please note, however, that when safety readback is enabled, a sensor error
will be indicated as an error on the analogue output signal.
CJC
In the CJC menu you can choose between CJC connector and internal cold
junction compensation. The CJC connecter (PR 5910) must be ordered
separately.
Memory
In the memory menu you can save the configuration of the device in the 4501,
and then move the 4501 onto another device of the same type and download
the configuration in the new device.
