Pin 15 - 24VDC supplied by internal power supply
Pin 16 – for supplying the Outputs with 24 V for Sourcing Outputs or 24 V Return for Sinking
Outputs.
If an Input pin icon is Clear, it is OFF. If the pin icon is Dark, the pin is ON. If an output has an
arrow moving it to the Normally Open pin it is ON.
There is a horizontal cursor under the pins. Use the left or right keys to move the cursor. The
bottom left corner of the screen indicates cursor location and the pin's assigned element.
Manually control the E/S by forcing elements either ON or OFF. Applying a force means the
pin will always be in that forced state and does not toggle to the opposite state (even if the
system requires it to toggle). This is useful for troubleshooting signals that integrate with other
equipment.
Use the horizontal cursor under the pins to select the pin to be forced. Press the toggle button to
bring up the force menu.
Use the up or down arrows to choose the force required then press the toggle button again to
execute the selected force. When the force is no longer required, use the Force Remove
selection to remove the force and return the pin to system control.
If an Input pin icon is Clear, or the Output pin has no arrow, with a small F icon that means it is
forced OFF. If the Input pin icon is Dark, or the Output pin has an arrow, with a small F icon,
this means the pin is forced ON.
If a force is active when one of the keypad buttons is pressed to exit the Diagnostico Screen,
the force will remain active. Enter the Diagnostico Screen again to remove the force.
Press a keypad button to save changes and return to the Run screen.
