Conditions for safe
measuring mode
"Increased security during parameter entry" method:
The device checks whether certain operating steps have been performed beforehand or whether
impermissible parameters have been configured.
The "Increased security during parameter entry" method is no longer possible after the following
operating steps:
• Position adjustment performed or measuring range set on site without using the onsite display.
• Following a download
• After a configuration backup using HistoROM
®
/M-DAT
• After a reset, apart from after the reset code "7864"
• After performing sensor recalibration (observe note, ä 22.)
• Following current trimming
• For the "LEVEL SELECTION" parameter, the "Level Easy Height" or "Level Standard" option was selected
(permitted setting for LEVEL SELECTION is "Level Easy Pressure").
The "Increased security during parameter entry" method is only possible again if a reset (code "7864")
is performed, thereby resetting all the parameters to the as-delivered state.
The reset (code "7864") must be performed to use the "Standard device configuration" method.
Permitted parameter setting
Only certain settings are possible for some parameters. If a setting that is not permitted has been
selected for one of these parameters, the "Increased security during parameter entry" method is not
possible. This method is possible once more as soon as the permitted setting is selected for the
parameter.
• If the device has assumed a fault condition, i.e. an alarm is output and the current output
assumes the set value, the cause of the fault must first be eliminated.
• "Level" operating mode, "Level Easy Pressure" level selection: The PRESSURE EMPTY and
PRESSURE FULL parameters are only displayed for the "Dry" CALIBRATION MODE.
If you have performed a wet calibration, you subsequently have to select the "Dry" option by
means of the CALIBRATION MODE parameter. You can read out the
corresponding values for the PRESSURE EMPTY and PRESSURE FULL parameters here.
• The sensor can only be recalibrated by Endress+Hauser Service. All parameters, except the
parameters for a sensor recalibration, are reset with the "7864" reset code. Therefore, the
parameters have to be checked prior to locking via the SAFETY CONFIRM. menu.
