This screen shows the state of inputs 1 to 8 from left to
right. See Figure 4.5. Since inputs are pulled high when
they are not connected, test an input by shorting it to con-
troller common and making sure this screen shows the cor-
rect state for that input.
Figure 4.5 Digital Inputs Screen
When you are done testing digital inputs, press YES or NO
to advance to the next screen, or press BACK to return to the
MANUAL I/O TEST menu.
Test Digital Output
Select one of the digital alarm outputs to test. You will test
the output on the next screen.
You cannot force the state of an output enabled for control.
Selectable values: Any output from 1 to 34 that is not en-
abled for closed-loop control or for the Serial DAC clock and
GA, the global alarm output.
Digital Output Number
This screen appears only if you selected an output that is
not in use for control at the TEST DIGITAL OUTPUT screen.
Use this parameter to manually toggle a digital output on
or off to test it. Toggling an output ON sinks current from
the output to the controller common. Toggling the output
OFF stops current flow. All tested outputs are set to OFF
when you exit the MANUAL I/O TEST menu.
You cannot toggle outputs enabled for control. To test a
control loop output, first disable it using the SETUP LOOP
OUTPUTS menu.
Selectable values: ON or OFF.
