CCBU40 COMPACT CONTROLLER BOARD - PRODUCT AND WARRANTY INFORMATION

STARTING AND OPERATING THE CCBU40
Warnings:
•
The supply voltage should never 32Vdc. Exc32Vdc will lead to permanent
damage of the CCBu40.
•
The wiring and mechanical installation should be performed before powering up the CCBu40.
•
Configuration switches should be set to the desired configuration before power-up.
First, the CCBu40 should be powered on by a nominal supplying a voltage b24Vdc and +28Vdc.
Note: Maximum peak output power may not be available if the power supply peak current is below 10A peak.
After power-
up, the green “Power” indicator should light.
The CCBu4
0 startup is controlled with the “Enable” digital input on the supervisor connector. When the “Enable”
signal is high (3.3V) or undriven, the CCBu40 remains in standby, and power converters are not activated. In
this mode, no motion can be applied to the actuators. In standby, the “Fault” LED and “Fault” signal are set to
indicate that the system cannot operate. In this mode, the power consumption is reduced. When the “Enable”
signal is brought low (0V), the CCBu40 launches the startup procedure. If the startup is successful (no fault
detected), the CCBu40 starts operating normally and applies the user commands. The CCBu40 can be
deactivated at any time by bringing the “Enable” signal high (3.3V).
The board is capable to detect 3 fault conditions:
•
Overtemperature
•
Overload
•
Missing connector (no mechanism is connected)
Upon startup of the board, the conditions are tested. If a fault is detected the board will go to fault mode, and
the red LED “Fault” will light to indicate the fault condition. In addition, the “Fault” output will be set to the high
level (+3.3V). In fault mode, the power converters are deactivated, and the board will not function properly. Fault
mode is equivalent to standby mode. To regain functionality after a fault, the user has to reset the board:
The “Enable” input should be asserted high (3.3V), and then low (0V) again to try to restart the board. If the
startup procedure is successful, the board will operate properly.
Overtemperature condition is constantly monitored during the system operation. If the overtemperature
condition appears during the normal system operation, the board will go to the fault mode. The same principle
applies for the missing connector detection.
Note: The
communication becomes active as soon as the green “Power” indicator lights. The
communication remains active even in Standby or Fault condition.
