7.9 Override Output
The Override Output feature allows you to manually change the state of any digital output to ON or
OFF, overriding automatic control by the AC4 (the default setting for all outputs). This menu also
allows you to release the manual override, returning any output to automatic control.
There are two ways to override automatic control of outputs:
• Use the Override Output menu, as described in this section, to turn any output ON or OFF.
• Use the hardware switch on the circuit board to force all four outputs ON at the same time
(see Item F - Manual Override Switch (outputs) in 1.6 - Controller Board Overview).
After an output is forced manually ON or OFF, it remains in that state until returned to automatic
control through this menu.
Table 20 summarizes the four types of control, including the abbreviated message that appears on
the LCD and in log reports.
To force an output point ON or OFF or return it to automatic control:
Log In and Choose Override Output
• From the Main Menu, use the arrows
↑↓ to choose System and
Control, then press Enter ↵ (see 7.1 - Login for help).
• Enter your password at the Login screen.
• From the System and Control Menu, use the arrows
↑↓ to choose
Override Output, then press Enter ↵.
Select an Output
The Select Output menu, shown at right, displays the current status
of all four outputs.
• Use the arrows
↑↓ to choose the output you want—for example,
Device_1—and press Enter ↵.
Turn Output ON or OFF / Return to Automatic
• From the Override Output menu, use the arrows
↑↓ to choose one
of these options:
• AUTO - return to automatic control
• FORCE ON - manually turn this output ON (operating)
• FORCE OFF - manually turn this output OFF
• Press Enter ↵.
