output or tag no.
Two-point process calibration (CAL): The device can be process-calibrated in 2 points to fit a given input signal . A low input
signal (not necessarily 0%) is applied and the actual value is entered via DRSL-DISPLAY/DRST-CM Then a high signal (not
necessarily 100%) is applied and the actual value is entered via DRSL-DISPLAY/DRST-CM. If you accept to use the calibration,
the device will work according to this new adjustment. If you later reject this menu point or choose another type of input signal
the device will return to factory calibration.
Process simulation function (SIM): In the menu point "EN.SIM" it is possible to simulate an input signal by means of the arrow
keys and thus control the output signal up or down. You must exit the menu by pressing 3 (no time-out).
The simulation function exits automatically, if the DRSL-DISPLAY/DRST-CM is detached.
Password (PASS): Here you can choose a password between 0000 and 9999 in order to protect the unit against unauthorised
modifications to the configuration. The unit is delivered default without password.
Language (LANG): In the menu "LANG" you can choose between 7 different language versions of help texts that will appear in
the menu. You can choose between UK, DE, FR, IT, ES, SE and DK.
Output function (OFUN): Here the output characteristics can be set to either Direct (DIR) or Inverted (INV) function. Output
type and range are set in the normal programming menu. If the selected output range is starting at zero, V-curved output
function (VFUN) can also be selected. The output characteristics will then be 100-0-100% on the basis of a linear 0-100% input
signal.
Auto diagnostics
The device performs an advanced auto diagnosis of the internal circuits - check tables on page 15.
