ALSTOM | 42011-106-00 | A01 ITC_VIOM_VIOC VER.A01 | Industrial control circuit board.The ALSTOM 42011-106-00 is also known as an interface board module. Some of its features and functions include:
Programming mode: By default, all startup modes are set to false to allow customers to program the device. An error check has been added to ensure that the rated speed (when programming for a generator set) is less than the maximum speed.
Service mode: The minimum load hold has been changed to come from the breaker logic harvester input. The previous hold change command was selected under the “Speed Control Settings” header.
Speed setting ratio: The minimum adjustment range setting point rate for all speeds has been changed to 0.01 (from 0.1).
Auxiliary limiter or controller: Logic has been added to ensure auxiliary control in case of input failure. The Aux re-enable logic has also been changed. The circuit breaker disconnect logic has been changed to correct the generator disconnect auxiliary actuator output fault.
Auxiliary controller: The speed setpoint auxiliary bias logic has been changed to allow only when the speed setpoint reaches the maximum control value. Before this, the limiter could be controlled during extreme transient periods.
