3. CONNECTING THE LOADER CONTROL
BOARD OF THE Series 16i/18i/21i
99
The loader I/O board has I/O signals for controlling the loader main body.
DI = 6 points (general–purpose 24–V input)
DO = 8 points (general–purpose 24–V source output)
DI = 1 point (24–V input for emergency stop)
The six input signals and eight output signals are used to open and close
the hand at the end of the loader arm as well as to control air blow and other
operations. The emergency stop input signal is used to stop the loader in
an emergency, for example, when loader overtravel is detected (by
hardware) or if the hand fractures.
