FOXBORO 0303458A Output logic card

Transformer Input Board The board must be supplied at X80 connector with:
1A, 50 Hz with accuracy class 0.5 at the 1A current inputs pins
0,2A, 50 Hz with accuracy class 0.5 at the 0,2A current inputs pins, normally on input channel 7 and/or 8
100 V RMS, 50 Hz. with accuracy class 0.5 at the voltage inputs Note During the calibration procedure all signals used calibration must be in phase! 6.3.3.2 Sensor Input Board The board must be supplied at the X81…X88 connectors at the same time with signals of 2V, 50 Hz with an accuracy class 0.5

In this case the board must be supplied at
X80 current inputs with 1A, 50 Hz with accuracy class 0.5
X80 voltage inputs with 100V, 50 Hz. with accuracy class 0.5
X81..X86 with 2 V, 50 Hz accuracy class 0.5 Before starting the calibration procedure, the protection unit housing must be grounded. Beside that, the shielding screw on the analog input board must also be in.

Remote HMI self test

 The following test procedure is applicable since the implementation of the software version 4B 01. To carry out the test the following steps must be done: Connect the power supply to the connector X10. Take care of the voltage level of the HMI. Switch on the power supply of the HMI Local Control Unit. The connection to the Central Unit shall be removed.

After entered 8th channel input settings the calibration procedure starts automatically the calculation of calibration factors and after some seconds, it ends. The report shows at the corresponding input lines the calibration result with channel accuracy. In case of wrong connections to the input a phase error will be reported. The following figure shows the returned messages of the calibration procedure in case of phase error.

By pressing the return key a “Stand alone” mode on the LCD display is shown. The test can be run individually or all together in sequence by selecting the corresponding menu line. In this case the e-key with the ABB code must be inserted in its plug and loop back cable must be inserted in X20 and in the optical interface in advance.

Serial ports test 

This test is performed by connecting the loop-back cable, cable that is normally used for the connection between PC and HMI Local Control Unit, between the port X20 and the optical connector on the HMI front panel.

Each keyboard buttons has to be pressed one by one, no matter the order. When a button is pressed the “PRESSED” string is displayed in the corresponding page line. When all buttons have been pressed, after 1-second delay, the test ends with OK result. If after 15 seconds not all buttons have been pressed, the test ends with FAIL result. After finishing the test, the HMI test page will be displayed again automatically.
