Forward/Reverse Direction Signal Entry From Table; No Function; Max-Alarm Entry From Table; Min-Alarm Entry From Table - ABB COPA-XE Instruction Bulletin

4.14.1.3 Forward/Reverse Direction Signal
Entry from table
Terminals P7/G2
F/R-Signal
The forward and reverse direction is indicated by an arrow in
the display and signalled over the contact terminals
P7, G2 (Ux, P7 for Profibus).

4.14.1.4 No Function

Terminals P7/G2
No Function
When "No Function" is selected there is no signal over
Terminals P7, G2 (Ux, P7 for Profibus).
4.14.1.5 MAX-Alarm
Entry from table
Terminals P7/G2
MAX-Alarm
When this output function is selected a signal is sent to the
terminals when the flowrate exceeds the limit value set, in this
case the contact opens. Setting MAX-Alarm see Sect. 4.13.2.
4.14.1.6 MIN-Alarm
Entry from table
Terminals P7/G2
MIN-Alarm
When this output function is selected a signal is sent to the
terminals when the flowrate drops below the limit value set, in
this case the contact closes.
Setting MAX-Alarm see Sect. 4.13.3.
Electromagnetic Flowmeter
4.14.1.7 MAX/MIN-Alarm
Entry from table
Terminals P7/G2
MAX/MIN- Alarm
When MAX/MIN-Alarm is selected a signal is indicated on the
terminals P7, G2 (Ux, P7 for Profibus) when the flowrate is
outside of the limit values set in MAX-Alarm and MIN-Alarm, i.e,
when the flowrate is greater than the MAX-Alarm value or less
than the MIN-Alarm value.
In this mode it is also possible to indicate when the flowrate is
within the two limit values set in MIN- and MAX-Alarm. In this
configuration the MAX-Alarm value must be set smaller than
the MIN-Alarm value. When the flowrate is within this range, a
signal is indicated in the display and on the terminals P7, G2
(Ux, P7 for Profibus).
F
F
MAX-Alarm = 20 %
MIN-Alarm = 80 %
A blinking double arrow indicates that the flowrate is between
20 and 80 %.

4.14.2 Terminals X1/G2 (not available for Profibus)

The functions which can be assigned to the input contacts can
be selected using the STEP/DATA keys:
• External zero return
• External totalizer reset
• External totalizer stop (not available for HART-Protocol)
• No function
These functions are not available for Profibus-Communication.
4.14.2.1 External Zero Return
Entry from table
Terminals X1/G2
Ext. Zero Return
This input function can be selected for terminals X1/G2 to turn
off the outputs (current and pulse) when the flowmeter is empty
or during a cleaning cycle (CIP).
