Terminals 1-2/A1-B1 and 3-4/A2-B2 are outputs of the 3-position enabling •
switch.
Terminals 5-6/A3-B3 are outputs of the monitor switch.•
The above operation characteristics show when the center of the grip style •
enabling switch button is pressed. Because two contacts are designed
to operate independently, pressing the edge of the button turns on one
contact earlier than the other contact, causing a delay in operation. To
avoid this, always press the center of the button.
