Processor features

The processor board is linked to an acquisition board dedicated to the function of the I/O pack or module. When input power is applied, the soft-start circuit increases the voltage available on the processor board. The local power supplies are turned on in sequence, and the processor reset is disabled.

After finishing self-test routines, the processor loads application code specific to the I/O pack or module type from flash memory. The application code reads board ID information to ensure that the application code, acquisition board, and terminal board are all correctly matched.

Auto-Reconfiguration

The Auto-Reconfiguration feature allows the operator to replace I/O packs without having to manually reconfigure each pack or module.

When the controller detects an I/O pack booting with a different configuration and the Auto-Reconfiguration feature is enabled, a reconfiguration file is automatically downloaded from the controller to the I/O pack. The bootload, baseload, firmware, and parameters are all reconfigured.

Unless it already has the latest version, each I/O pack is updated with the current configuration that matches the configuration used by the controller.

Analog Input Hardware

For all ten input channels, the PAIC accepts input voltage signals from the terminal board. An analog multiplexer block, several gain and scaling options, and a 16-bit analog-to-digital converter comprise the analog input section (DAC).

Depending on the input configuration, the inputs can be configured as 5 V or 10 V scale signals. When configured for current inputs, the terminal board includes a 250 burden resistor that produces a 5 V signal at 20 mA.

Analog Output Hardware

The PAIC has two 0-20 mA analog outputs that can operate at 18 V compliance in simplex or TMR mode. A 14-bit DAC sends a current reference to the PAIC’s current regulator loop, which detects current in both the PAIC pack and the terminal board.

Each analog output circuit also includes a normally open mechanical relay for enabling or disabling output operation. The relay is used in a TMR system to remove a failed output, allowing the remaining two PAICs to create the correct output without interference from the failed circuit.

When the suicide relay is deactivated, the output opens through the relay, short-circuiting the PAIC’s analog output from the terminal board’s customer load.

Hardware Tips and Specifications

This DS200TCEAG1B Emergency Overspeed Board has its own particular set of hardware component inclusions and specifications, as revealed in original Mark V Series instructional manual documentation. The General Electric Emergency Overspeed Board model DS200TCEAG1B features one microprocessor and multiple programmable read only memory (PROM) modules. It also contains 3 fuses, 30 jumpers, and a pair of bayonet connectors. The DS200TCEAG1B board monitors the Mark V Series drive for over speed and flame detection trip conditions and shuts down the drive as appropriate. The bayonet connectors in the assembly of this DS200TCEAG1B Emergency Overspeed Board are used to connect the board to other devices and boards in the drive; these male bayonet connectors on the end of the cables require some consideration before you connect www.cniacs.com them to the female connectors on the board, as detailed in depth in GE instructional manual materials. To remove a bayonet connector, hold the connector with one hand and with the other hand secure the board to keep it from bending or moving. Pull the bayonet connector out of the female connector on the board and put the cable aside until you are ready to connect it to the replacement board.

Several specific connectors and integrated circuits are incorporated into the assembly of this TCEA-abbreviated PCB. This DS200TCEAG1B Mark V Series printed circuit board’s circuits are tasked with various diagnostic functions relating to this DS200TCEAG1B PCB’s greater overspeed processing functionality. Some of these integrated circuits include the TCEA Flame Detection Circuits, the TCEA Turbine Overspeed Circuit, and the TCEA Automatic Synchronizing Circuit. Each of these circuits has been named in terms of their functionality to the greater DS200TCEAG1B printed circuit board and Mark V Series automated drive assembly.The various connectors made available to owners of the DS200TCEAG1B Emergency Overspeed Board comprise of:

The J7 PD Core Power Distribution Connector

.The JK TCEB Board Signal Connector

.The JL TCTG Board Trip Signal Connector

.The JW TCEB Board Flame Detection Signal Connector

.The JX1 and JX2 Daisy Chained IONET Connectors

Similarly to the integrated circuits discussed above, all of these connectors available in the assembly of this DS200TCEAG1B printed circuit board have been described in terms of their factory-printed nomenclatures and intended applications. All of the hardware in the assembly of this TCEA-abbreviated Emergency Overspeed Board should receive at least some basis of protection from the thick protective layer offered by this DS200TCEAG1B PCB’s normal style of PCB protective coating.
