Page 11: Installation
• The ACT2000C01 module and the mounting frame should always be installed, maintained, operated and removed by personnel with sufficient technical qualifications. The equipment should never be placed in damp areas, near splashing liquid, or in explosive or corrosive atmospheres. -
Page 12: Environmental Considerations
1 - Remove the blank panel covering the front of the empty slot chosen for installing the ACT2000C01 in the mounting frame. 2 - Insert the ACT2000C01 module into the front of the mounting frame. The edges of the card slide into two plastic guides inside the mounting frame. -

- As indicators of an error in the inputs: GPIO1 for the Main input (MAIN) and GPIO2 for the Reserve input (RES). This mode of use of the GPIOs is suitable for using two ACT2000C01 as an automatic switch for a pair of stereo audio signals. - Page 14 Albalá Ingenieros | Manual ACT2000C01 SWITCHING USE OF GPIOs GPIO1 GPIO2 MODE Full auto Main input Reserve input Half auto Close: Fail Close: Fail Manual Open: Ok Open: Ok Input selection Level Close: Reserve Open: Main When clossing When clossing...

Page 17: Operation
Albalá Ingenieros | Manual ACT2000C01 4. OPERATION This section describes the significance of the front panel indicators of the ACT2000C01 module and their remote control and monitoring ability. 4.1. Front panel description The appearance of the front panel and the elements it contains are shown in the following illustration. -
Page 18: Configuration From The Front Panel
The ACT2000C01 automatically selects the higher priority, error-free input at all times. In the case of an error present in both inputs, the ACT2000C01 stays with the input that was selected prior to the appearance of the error. The Main input is higher priority and the Reserve input is lower priority by default, however this can be inverter using the control software. -
Page 19: Semiautomatic Mode Operation
These values come programmed by default from the factory as zero and 500 ms, respectively. In addition, when an error occurs in one input the ACT2000C01 only switches to the other input if the other input has a valid signal. 4.3.2. Semiautomatic Mode operation This operating mode minimizes the amount of input switching. -
Page 20: Gpio Mode Operation
ACT2000C01 4.3.5. GPIO Mode Operation This mode of operation is suitable for using two ACT2000C01 as an automatic switch for a pair of stereo audio signals. The GPIO1 and GPIO2 terminals of each of two modules must be connected with the respective terminals of the other module. -
Page 21: Module Remote Control And Supervision
Albalá Ingenieros | Manual ACT2000C01 4.4. Module remote control and supervision The ACT2000C01 can optionally be remotely controlled/supervised. In order to perform remote configuration and supervision of the module an optional TL2000 family remote communications controller must be installed in the mounting frame. -

- Supervision of the status of the input signals being received. 4.4.1. Details of the ACT2000C01 registers The ACT2000C01 module provides control and status registers that can be read and written by means of specific commands described in the communication control module user manuals. - Page 23 Albalá Ingenieros | Manual ACT2000C01 GPI_OP_MODE 0x02 0x10 Allows selecting the GPI operation mode 0=Level, 1=Edge GPO_OP_MODE 0x02 0x20 Allows selecting the use given to GPOs 0=Signal status,1=Input selection GPIO_POL 0x02 0x40 Changes GPIOs polarity to normally closed 0=Normal, 1=Inverted...
