Programming the IQ 250/260 IQ 250/260 Meter
3. Select
Group
for your
Output Channel
. The available
selections are as follows:
• Readings
• Demand
• Maximums
• Minimums
• Phase Angles
• THD
• Not Assigned.
4. Select
Item
for your
Output Channel
. The items are the available readings for the group you selected.
For
example
, as shown in the window above, Volts A-N is an item you can select when you have selected Readings
as the Group.
5. Click
OK
. The Output Channel you selected is displayed in the Assigned Channel field.
6. Enter
Low End
and
High End
for the channel.
NOTE
: For the Item selected for the Assigned Channel, the Output Card takes the value in the meter and outputs a
DC current within its range. The Low End is the lowest value, and the High End is the highest value. For example,
for VOLTS A-N and Bidirectional Mode, at Full Scale of 120V, the Low End is 115V and the High End is 125V. The
Analog Output Card will output –1 mA when the reading is 115V, 0 mA when the reading is 120V, and 1 mA when the
reading is 125V.
7. You can select either
Unidirectional
or
Bidirectional
for
Mode
.
8. Enter an
Update Rate
. The
suggested rate
is between 100 and 200 msec.
Configuring a 4-20 mA Output Card (IQ250/260-IO4):
The
4-20mA Output Option Card
is an
analog communication card
, which transmits a standard, uni-directional
4-20 milliamp signal.For technical specifications and hardware installation, see Chapter 7 of this manual.
An example use of the optional 4-20mA Output Card is in enabling the meter to communicate with an RTU (Remote
Terminal Unit).
Click
4-20 mA Output
.
Follow the instructions for configuring the
0-1 mA Card. The configuration of a 4-20 mA Card
is the same as a 0-1 mA Card, except that this card
can only be unidirectional
.
