for the Toggle Valve. However, prior to teaching the offset, the toggle
valve bit configuration must first be completed.

of the screen.
2. Select "Configuration" to configure the
toggle bit (the internal I/O instruction to
turn on the solenoid for the toggle
bracket).
3. Enter the desired I/O bit to turn on the
air solenoid i.e. will cause the toggle
bracket to shift. Select Output Bit 7
for EXT_SOLENOID_B or Output Bit 6
