Configuring a Relay Output/Digital Input Card (IQ250/260-IO1):
The
Relay Output/Digital Input Option Card
has:
· Two relay contact outputs for load switching
· Two wet/dry contact sensing digital inputs.
Accumulators
in the software count the transitions of the Inputs and Outputs.
For technical specifications and hardware installation, refer to Chapter 7 of this manual.
NOTE
: When installing a Relay Output/Digital Input card, we recommend you
reset the accumulators
for the card,
in order to prevent erroneous counts. See instructions on using the Reset Device Information screen to reset card
accumulators, later in this chapter.
An
example
use of the optional Relay Card is in monitoring the status of circuit breakers or relays in your electrical
system. The two status inputs could be used to monitor two circuit breakers, and the two relay outputs could be used
to sound an alarm upon the occurrence of a programmed out of limit condition (IQ 260, only). Relay outputs on IQ
250/260 can be manually triggered: see the “Performing Manual Relay Control” section, later in this chapter.
Click
Relay Assignments
to set the
limits/alarm conditions
(IQ 260, only) and
labeling and compression op-
tions
for the card’s
Relay Outputs
. From the
Relay Assignments
screen, you can:
• Configure up to
8 limits
for each of the two Relay
Outputs (IQ 260)
• Set a
Delay
and
Reset Delay
for the Outputs (IQ 260)
• Assign each Output an
Output Label, Open Label,
and
Closed Label
• Assign an
Accumulation Compression Factor
for
each output
I
MPORTANT!
First use the Limits screen to set up the
limits you want to assign to an Output. See
instructions earlier in this chapter.
NOTE:
The Limits functionality is only available for
the IQ 260. If you are connected to an IQ 250, you
will only see the Label and Accumulation
Compression Factor fields in this screen.
1. The
available Limits
appear in the
Limit ID
column.
To
assign
a
Limit
to an Output Relay:
Select
the
Alarm trigger
from the
pull-down
menu
next to the
Limit ID
. The options are:
•
Above Limit
(the Output is triggered when the Above Limit condition occurs)
•
Below Limit
(the Output is triggered when the Below Limit condition occurs).
You can assign the limit to one or both (or neither) of the Relay Outputs.
NOTE
: A Relay operates when any one assigned Limit is tripped, and stays in the Set condition as long as one
Limit is in the Alarm state.
2. You can enter
Set Delay
and/or
Reset Delay
. These values are the delay before the Output is changed:
Set
is
when the common is shorted to
Normal Open
(this is the
Set Condition
).
3. The
current Output Labels
are displayed in the screen. These labels are used for Logging. To
change
the
Output labels, click in the Labels field you want to change, and enter a new label. The fields that can be changed
are:
•
Output Label
– Label ID
•
Open Label
– Open state ID
•
Closed Label
– Closed state ID
