ON/OFF Control Module
To configure an ON/OFF control module on a device, first ensure that the desired output pin is not
associated with any input alarms and that it is set as
No Mapping
in the Output Mapping menu in the
Outputs
tab. The ON/OFF control module can be used with any selected output type including ON/OFF,
PWM, and SERVO. When enabled in PWM mode, ON corresponds to 100% duty cycle. When enabled in
SERVO mode, ON corresponds to 100% angular travel.
In the
Outputs Tab
in SYNC click on the
icon located to the right of the available outputs. Clicking the
icon will open the
Define ON/OFF Control
dialog box as seen below.
The
Enable Control
checkbox enables the ON/OFF control module. If this box is unchecked, the output will
be disabled but the module with all its settings will remain available to be enabled at a later time.
The
Inputs
dropdown lists the available input sources and will depend on how the device is configured in the
Inputs tab.
The
Setpoint
field sets the threshold for activating the ON/OFF control module. The unit of the Setpoint field
will be the same as the unit of the chosen Input.
The
Control Actions
dropdown has options for direct or reverse control. In direct mode, once the Setpoint
value is reached then the output will be set to ON. In reverse mode, once the Setpoint value is reached then
the output will be set to OFF.
The
DeadBand
field together with the direct or reverse control action configures a deadband range around
the Setpoint where the ON/OFF control does not toggle. The unit of the DeadBand field will be the same as
the unit of the chosen Input.
•
Example 1:
the setpoint is configured for a 50 Hz rate input with a deadband of 10 Hz with
direct
control action. The output will activate if the input rises above 60 Hz. Conversely, the output will
become inactive if the input falls below 50 Hz.
•
Example 2:
the setpoint is configured for a 50 Hz rate input with a deadband of 10 Hz with
reverse
control action. The output will activate if the input falls below 40 Hz. Conversely, the output will
become inactive if the input rises above 50 Hz.
The
Save
button saves and applies the configurations settings to the ON/OFF control module. The
Delete
button only appears for a previously saved ON/OFF control module and it removes the module and allows
other output types to be configured such as an alarm or mapping.
