Override Outputs

You use the override display to manually override digital outputs as well as analog outputs.

Warning Warning

Unintended equipment operation

Do not override outputs without knowing the effect.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

There are basically two control modes:

  • Hand mode

  • Auto mode

You place an output in Hand mode when you want to manually override the output. Programs have no effect on the output in this mode. The meaning of the Hand mode for the different output types are described below.

You switch back to Auto mode when you want to remove the manual override. In Auto mode, programs control the output.

The Output Override screen is similar for the different output types. For more information, see Output Override Screen .

indicates that an output point is manually overridden. For more information, see Icons .

Override Analog Outputs

In Hand mode, you can manually adjust the analog value of an analog output.

Override Digital Outputs

In Hand mode, you can manually activate or deactivate a digital output by selecting one of the following options:

  • Hand On makes the output activated (on).

  • Hand Off makes the output manually deactivated (off).

Override Digital Pulsed Outputs

In Hand mode, you can manually adjust the duty cycle value of a digital pulsed output.

Override Tristate Outputs

In Hand mode, you can manually control a pair of tristate outputs by selecting one of the following override values:

  • On makes the first output active (on).

  • Off makes both outputs inactive (off).

  • -On makes the second output active (on).

Override Tristate Pulsed Outputs

In Hand mode, you can manually adjust the duty cycle value of a pair of tristate pulsed outputs by selecting one of the following override values:

  • [Value] percent makes the first output active (on) in [Value] percent of the pulse period.

  • 0 percent makes both outputs inactive (off).

  • -[Value] percent makes the second output active (on) in [Value] percent of the pulse period.

For example, if you select 10 percent, the first output is active (on) in 10 percent of the pulse period. If you select -10 percent, the second output is active (on) in 10 percent of the pulse period.
