Example
: For the percent of angular travel, if the pulse width range is set to a range of 1.0-2.0 msec, then
selecting 50% of angular travel represents 1.5 msec or 90 degrees of travel.
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.
