1.4.2. Digital Output Enable
The
Enable Source
will determine whether the relay output will be commanded by the
Control
Source
. There are six different
Enable Responses
in which the enable signal can be used. These
responses are listed in Table 7, where the default value is highlighted.
Value Meaning
0
Enable When ON
1
Enable When OFF
2
Disable When ON
3
Disable When OFF
4
Enable When ON Else Keep State
5
Enable When OFF Else Keep State
Table 7: Enable Response
When the
Enable Response
is set to
Enable When ON
or
Disable When OFF,
the relay output will
be commanded according to the signal of the
Control Source/Number
and the
Output Type
only
when the signal of the
Enable Source/Number
is ON. Otherwise, the output is commanded to the
OFF state (
Output Type
selected).
Similarly, when the
Enable Response
is set to
Enable When OFF
or
Disable When ON
, the output
will be commanded according to the
Control Source/Control Number
and the
Output Type
only
when the signal of the
Enable Source/Enable Number
is OFF. Otherwise, the output is
commanded to the OFF state (
Output Type
selected).
In case the
Enable Response
is
Enable When ON Else Keep State
, the relay output will be
commanded according to the signal of the
Control Source/Number
and the
Output Type
only
when the signal of the
Enable Source/Number
is ON. If the Enable Source is OFF, the output will
keep the previous state.
Likewise, when the
Enable Response
is configured to
Enable When OFF Else Keep State
, the
relay output will be commanded according to the
Control Source/Number
and the Output Type
only when the
Enable Source/Number
is OFF. Otherwise, the relay output holds the previous
state.
A time delay for both states (ON, OFF) can be set by setting the
Enable Response Delay
parameter to true. The values of these time delays can be set with the parameters
Enable OFF
Delay
and
Enable ON Delay
. In this case, the delays are valid for the enable state and the control
state.
1.4.3. Digital Output Control
When the output is being commanded by the
Control Source
, the selected
Output Type
parameter determines what logic is used.
The
Output Type
parameter allows for flexibility in the response of the output. Table 8 shows the
options available for this parameter.
