Kundendienst HEIDENHAIN DR JOHANNES HEIDENHAIIN GnlbH Di3292Traunieut~ W(O8669) 31-O SERVICE MANUAL TNC 407/415 Issue: 01.09.1995 Page 36 8.4 Checking the Power Supply (Power Supply Unit) Two low-voltage fuses are located on the power supply assembly. The fuse F 2.5A protects the output voltage of +24V BE ‘1, and the fuse F 4.OA protects the remaining voltages (see block diagram, section 8.3.1). If an error occurs in the power supply (all voltages are missing), first check the +24V at the supply line and then the lowvoltage fuses. By means of the test load unit, the power supply can be checked fast and easily. For this purpose the connectors to the power supply boards must be disconnected from the power supply and connected to the test load unit. The different values can be measured at the sockets of the test load unit with a multimeter. The values and their tolerances can be seen from the table in section 8.3. If the measured values deviate distinctly from the values in the table, the power supply assembly is defective. If no test load unit is available, the voltages can be measured at the measuring points on the processor board, the CLP board or the PLC graphics board. (Measuring points: see section 8.5) 1) The voltage of +24V BE is not required for the TNC 407/415. as the VDU has its own power supply, NOTE: Always switch off the main switch before engaging or disengaging any connectors The power supply unit does not function during free-run (basic load is required).
