6.3. THE DISPLAY SHOWS THE MESSAGE "THE EQUIPMENT IS
BLOCKED (COM)"
The (COM) error indicates that there is no communication between the two KITs. This may
occur essesntially in the following cases:
1. Interruption in communication on the serial line between the Display Board (High Kit) and the
Brake Board (Low Kit): communication cabling is defective, replace cabling;
2. The SW of the Brake Board Firmware (FW) and/or the Brake Table is incorrect /corrupt:
example where the operator manually loads the FW and chooses the wrong one. The solution is
to re-load the Firmware (FW) (an action which is always possible for any Brake Board);
3. The SW of the Display Board is incorrect /corrupt: the High Kit SW has not been upgraded -
proceed with upgrading.
The error is displayed with a message on the display and recorded in the "Errors Log" section.
In order to re-instate communication between the High Kit and the Brake Board, proceed as follows:
(1) Check that the Serial Communication Cable (CU196) is intact, by using the Test Box Excite
and if necessary, replace it.
(2) Upgrade the SW on the Brake Board by loading: the Firmware (FW) and the Brake Table
and run the Standard Setting.
(3) Upgrade the SW on the Display Board.
(4)
Try and replace the Brake Board and the Display Board one at a time and check whether the
serial communication is re-enabled (you can use a standard network cable for the test).
If the Display Board is replaced, check that the upgraded SW version is installed or
proceed with the upgrade.
If the Brake Board is replaced, check that the correct SW version is installed or
proceed with the upgrading of the Firmware (FW), the Brake Table and the Standard
Settings.
