4.13.3 Setting the MIN-Alarm

MIN-Alarm
10 %
The limits for the desired MIN-Alarm value can be set in 1 %
steps from 0 % to 130 %. This value applies to both the forward
and reverse flow directions.
Note:
The limit values for the MAX- and MIN-Alarms
incorporate a hysteresis of 1 %.
When MIN-Alarm is selected the contact is actuated when
the flowrate drops below the limit value set. If this occurs, a
downward pointing blinking arrow is displayed.
R
R
MIN-Alarm limit value = 10 %
For flowrates < 10 % a downward pointing blinking arrow is
displayed next to the direction indicator in the 1st line. If the
MIN-Alarm value is set to 0 %. the option is turned off and no
alarm arrow is displayed when the flowrate drops below the val-
ue.
4.14 Submenu "Prog. In-/Output"
Entry from table
In this submenu various in- and output functions can be
programmed for the contact terminals P7/G2 or X1/G2.
Output functions: Terminals P7/G2
Input functions: Terminals X1/G2.
For Profibus-Communication the contact input terminals
(X1/G2) are not available and the output functions are assigned
to terminals Ux/P7.

4.14.1 Contact Output Terminals P7, G2
(Ux, P7 for Profibus)
The functions which can be assigned to the output contact
terminals P7, G2 are listed below:
General alarm (Errors 0-9, A, B)
Empty pipe
F/R direction signal
No function
MAX-Alarm
MIN-Alarm
MAX/MIN-Alarm
Warning
*Can be configured to open or close. The selection is
made using the STEP/DATA keys.
Open function, i.e. the contact opens when actuated.
Close function, i.e. the contact closes when actuated.
4.14.1.1 General Alarm (Errors 0 to 9, A, B)
Entry from table
Terminals P7/G2
General Alarm
All errors detected (Errors 0 to 9. A. B) are signalled at the
terminals. During an error conditions the terminals P7. G2
(Ux, P7 for Profibus) are activated, in this case, opened.
4.14.1.2 Empty Pipe
Entry from table
When the parameter "Empty Pipe Detector" (Sect. 4.18.1) is
turned on, the current output is set to 3.8 mA, 0 % or 100 %
when an empty pipe condition is detected and the totalization
halted. The empty pipe contact is activated, in this case, opens,
and the messages "Empty Pipe" and "Error 0" are displayed.
