The control input bits can be tested by applying a trigger voltage to an input and
watching changes in the status of the associated function under the SIGNAL I/O
submenu:
EXAMPLE: to test the “A” control input:
1. Under the DIAG SIGNAL I/O menu (See Section8.1.3), scroll through the inputs
and outputs until you get to the output named 0) CONTROL_IN_1.
2. Connect a jumper from the
“+” pin on the appropriate connector to the “U” on the
same connector.
3. Connect a second jumper from the “” pin on the connector to the “A” pin.
4. The status of 0) CONTROL_IN_1 should change to read “ON”.
