Deltabar S
22 Endress+Hauser
Checks After entering all the parameters, check the safety function prior to the locking sequence by means of
the SIMULATION MODE parameter or by approaching the limit pressure, for example.
( Operating Instructions BA00274P/00/EN SIMULATION MODE parameter description.)
The entire safety function should be checked after each change to the Deltabar S as part of a safety
function, e.g. a change to the orientation of the device or the configuration.

The parameters must meet the following requirements:
• The pressure values for SET LRV and SET URV must be within the
sensor measuring range.
following graphics, point 1.
• The turndown, which is determined by the difference between the
pressure values for SET LRV and SET URV, must not be larger than
the maximum turndown (100:1 at factory).
following graphics, point 2.
• The value for PRESSURE FULL – PRESSURE EMPTY must not
fall below the minimum span (1% of sensor measuring range).
following graphics, point 3.

5)
1) Only from firmware version ≥ 02.20
2) Not for options with measuring range, e.g. 160/250 bar [2320/3625 psi])
3) For firmware versions ≤ 02.20.04, settings are reset to permitted default values once the SIL password is entered (heed "Warning" notice ä 13)
4) For firmware versions ≤ 02.20.04, the "Min. alarm" setting is only possible with the "Standard device configuration" method.
5) With the "Increased security during parameter entry" method, any simulation running is terminated automatically once the correct password has
been entered.
Parameter and menu path Permitted settings
• 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.
• When operating via the DTM, locking via the SAFETY LOCK menu is only possible in the online
mode.
• 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.
