3C.7.4 I/O Configuration (Cont)
Pressing the button next to the selected input or output on the left of the display selects that function. The level of the selected state is
changed by pressing the selection button again (low = off / inactive, high = on / active).
For inputs, setting the level “low” means that the input is ignored during that state. Setting the level “high” requires that the
corresponding input is satisfied before the generator will advance to that state. For example, if the door interlock (DOOR ITLK) is set to logic
“low” for all states, then an X-ray exposure may be made without a door interlock closure.
Setting an output level “low” causes the relay associated with that output to be de-energized during the selected state. Setting the
level “high” will cause the associated relay to be energized during the selected state. For example, the Bucky 1 “start” output will be disabled if
BKY 1 START is set to “low” for all states.
The example below shows a TYPICAL input configuration.

1 = STANDBY STATE (shown low/inactive)
2 = PREP STATE (shown high/active)
3 = GEN RDY STATE (shown high/active)
4 = RAD EXP STATE (shown high/active)

tabs, the generator states are shown above the vertical grey / red bars (grey / white for Touchscreen
GenWare

). For inputs, grey indicates states where the input cannot be programmed. Only states that are shown in red (white) can be
changed. Outputs are programmable for each of the four generator states.
The logic level of the selected state is changed by clicking in the desired state column, to the right of the selected input or output (unchecked
= off / inactive, checked = on / active).
For inputs, an unchecked state means that the input is ignored during that state. A checked state (marked with an
X
) requires that the
corresponding input be satisfied before the generator will advance to that state.
For outputs, an unchecked state causes the relay associated with that output to be de-energized during the selected state. A checked
state (marked with an
X
) will cause the associated relay to be energized during the selected state.
