Prepare <strong>TNC</strong> for code number input<br />
Enter code number, acknowledge with ENT<br />
Soft key >TABLE< to display the tables<br />
Soft key >OUTPUT< to display the output table<br />
Now the logic states of the outputs are displayed on the screen. The states of the screen display must<br />
correspond to those of the test unit. If there is a difference, test the connecting cable for short circuit and<br />
measure the output current at interface (max. 100 mA for LE outputs, max. 1.2 A for PL outputs). If the<br />
output current is not exceeded and the connecting cable is in order, the output board is probably defective<br />
(00 to 030 of processor board, 032 to 062 of I/O board PL 400).<br />
