NOTE:
If [``no] is selected
for [`In2] none of
the other input 2
prompts will
appear.
Input 2
Select sensor type for input 2. This selection must match the sensor
type connected to terminals 18, 19 and 20. See Appendix for more infor-
mation about sensors.
• Changing the value of [`In2] changes all other prompts to the facto-
ry default values, except the Communications and Lockout menus,
the [`C_F] prompt in the Global Menu and the [`dFL] prompt in the
Calibration Menu. If you change the value, the default warning
[dFLt] will flash in the upper display.
• Changes do not take effect automatically after five seconds; you must
press the Mode key µ to enter the sensor type change and advance to
the next prompt.
[`In2] This prompt and other Input 2 prompts appear only on controllers
equipped with input 2 hardware (not 98_ _-_0_ _-_ _ _ _).
